i.e. when wrap-width > 0. This was only being done for non-grid cases.
So, ComboBoxes in grid mode did not indicate their selection when popped
up and required users to keynav from ‘nothing’ (at the top-left) to the
item they wanted to select. By selecting the active item in advance, now
it’s highlighted & acts as the starting point for keynav around the grid
This previously only mentioned its effect on the displayed value, and
even after the previous commit, its rounding of the actual value upon
change still reads like too much of an afterthought. Worse, it wasn’t
mentioned at all in the doc for the @digits parameter. Change this to
emphasise rounding always occurs and the displayed value is secondary.
Whether it should is an open question, but for now, the documentation
should clearly indicate that currently rounding is only applied upon
changes to the value, not to the existing value when ::digits changes.
This is already clear in the doc for the underlying Range::round-digits.
https://bugzilla.gnome.org/show_bug.cgi?id=358970
The documents state that gtk_scale_set_digits() “causes the value of the
adjustment to be rounded off to this number of digits, so the retrieved
value matches the value the user saw.” Note the lack of any condition.
But in fact, if draw-value was false, rounding was disabled on the base
Range, so values that weren’t displayed weren’t rounded. This made the
docs wrong and made an apparently cosmetic detail alter functionality.
Fix by ensuring the number of digits set on Scale is always propagated
along to gtk_range_set_round_digits(), thus rounding to it in all cases
when the value changes, regardless of whether the value is displayed.
This doesn’t address the other idea from Bugzilla: that changing the
number of digits should clamp the _existing_ value if it’s more precise.
This contradicts digits docs in the base Range, but the above from Scale
can be read as implying it’ll happen. For now, that’s an open question.

GtkFileChooserButton installs a handler for the popped-up signal, which
refilters the menu, in order to hide the “(None)” item from the popup
if it was previously selected in the ComboBox. This oddity means that:
• Until recently, this item would be selected in the menu shell, which
would then be popped up and change the selection away from that item.
This was therefore redundant (more on which below!) but benign.
• After the patch for https://bugzilla.gnome.org/show_bug.cgi?id=771242
however, this causes a critical assertion fail, as now we stash the
originally selected item in a pointer so that it can be selected only
after realisation/popup – but by that stage, the model has just been
refiltered and the previous pointer no longer refers to a valid item.
This commit works around this problem by, after popping up the menu,
getting the active item again, in case a popped-up handler has gone and
invalidated the pointer to the active item that we saved before popup.
If a handler does this, everything done to find/use the original item is
pointless. But this avoids the ugly critical in FileChooserButton, while
not harming every other ComboBox that doesn’t mess with its model while
popping up (hopefully the vast majority), and it’s very difficult to
imagine a way to check if the active item is /going to/ be hidden later)
Previously, for compatibility with GTK 3.0, we allowed specifying
numbers without units and interpreted them as pixels, even when the CSS
specification didn't.
Remove that now that we can break API.
This reverts commit 4875c689a0.
This was a thinko. Writable is not actually settable from the
application side, but only for the user, from the backend side.
Elsewhere we already go through the keymap to get modifiers so we
should do the same here. In fact, this was relying on xkb modifier
mask values being bitwise compatible with GdkModifierType which isn't
necessarily true.
https://bugzilla.gnome.org/show_bug.cgi?id=770112
Gtk+ treats MOD1 as a synonym for Alt, and does not expect it to be
mapped around, so we should avoid adding GDK_META_MASK if MOD1 is
already included to avoid confusing gtk+ and applications that rely on
that behavior.
https://bugzilla.gnome.org/show_bug.cgi?id=770112
When a subsurface is used as a parent of a popup, GDK needs to traverse
up to the transient-for as the next parent, to properly find the parent
used by the popup positioner. This is because the parent of a popup
must always either be an xdg_popup or an xdg_surface, but traversing
the "parent" (in GDK terms) upwards from a subsurface will end up on
the fake root window before we hit the actual parent (in Wayland terms).
https://bugzilla.gnome.org/show_bug.cgi?id=776225
Instead of having 3 different shaders for the different clipping
versions, just have one shader and use a preprocessor define to use
different clip functions.
That preprocessor define is set in the Makefile.
Also use foo.frag and foo.vert as the file extensions instead of using
foo.frag.glsl and foo.vert.glsl, as that's what glslc suggests as
extension.
That way we don't need to move the clip rounded rect manually through
the vertex shader into the fragment shader but can just look at the push
constants.
Simplifies shaders a lot.
Passing a rectangle with zero width or height to xdg_shell-v6
set_anchor_rect() will cause a protocol error and terminate the client,
as with gedit when pressing the Win key.
Reason for this is because the rectangle used to set the anchor comes
from gtk_text_layout_get_iter_location() which uses the pango layout
width/height, which can be empty if there is not character at the given
location.
Make sure we don't use 0 as width or height as an anchor rectangle to
avoid the protocol error, and compensate the logical position of the
given rectangle if the size is changed, so that the actual position
remains as expected by the client.
https://bugzilla.gnome.org/show_bug.cgi?id=777176
Images with just an aspect ratio, but without a size, should be scaled
to be fully visible in the given area.
But we scaled them to completely cover the given area, which made them
partially invisible.
Reftest included.
gtk_snapshot_pop() => removed
gtk_snapshot_pop_and_append() => gtk_snapshot_pop()
So now there is no way to get a rendernode out of the snapshotting API
until you gtk_snapshot_finish().
... and use it.
The function is a bit awkward because it requires 2 calls to
gtk_snapshot_pop(), but once you accept that, it's very convenient to
use, as can be seen by the 2 implementations.
This is a free-form tab that can contain information about the
system environment. To see it, set GtkAboutDialog::system-information
to a non-NULL value.
https://bugzilla.gnome.org/show_bug.cgi?id=776604
The Mesa Vulkan drivers need XInitThreads() being called, because their
implementation has to use threads.
And I don't want to make the call depend on if Vulkan is compiled in
because that makes GTK's X11 behavior depend on compile-time flags, so
it's always called.
This way, we ensure that files that are built during make always get
properly listed. And we ensure that creating the resources actually
depends on them.
We already take ints when setting the translation, so it can't
currently take any other values. Additionally, I was seeing large
costs in int -> double -> int for the rects in
gtk_snapshot_clips_rect(), as all callers really are ints (widget
allocations) and the clip region is int-based.
This change completely cleared a 2% rectangle_init_from_graphene from
the profile and is likely to have nice performance effects elsewhere
too.
The width/height/aspect getters are called a lot, and almost all
callers already verify it from _gtk_css_image_get_concrete_size (),
so just skip these checks.
This means we allocate the collect data with the state, avoiding
an extra allocation. Also, a union means every state object
is the same size and we could reuse the state objects.
This was showing up quite high on the profiles, and there is
no real reason for copy to normalize, as the source is a
GskRoundedRect which should be normalized already unless
you did something very strange (and then you should have normalized
manually).
Simgle image cross-fade opacity was computed the wrong way, which caused
weird fade-in/out animations, for example in flat buttons.
I messed this up when porting cross-fades to snapshot().
Since the demise of theme engines, we can no longer hit
the case of id >= GTK_CSS_PROPERTY_N_PROPERTIES. So don't
check for this in a very frequently called function.
Using an image() fallback from svg to png doesn't make too
much sense, since the svg is always used (unless librsvg is
not present), while the png icon is faster and cheaper to
load and thus preferable.
Also, "ie" wasn't very clear, but fixing that to "i.e." would cause
truncation of the summary when processed by bindings using doxygen. So,
I replaced it with "in other words", which is no _less_ clear, at least.
It was suggested that the project files to be moved to win32/, so that we can
have one less layer of directories we need to go down into to reach the project files.
Tell people about what happens when generating projects when Visual
Studio 2013 or later is required, and mention that the .headers are
only needed when headers need to be copied.
So we can set the css name of a widget to something that's not related
to the class name. If the css-name property is set to NULL, we will
still fall back to the one set using gtk_widget_class_set_css_name which
is alwasys non-NULL since GtkWidget itself sets it to "widget".
Instead of relying on --generate-dependencies and the resource file,
actually list the resources in Make variables.
Fixes make not building new shaders because they're not inside the
resource file.
See the implementation of gtk_entry_create_layout():
pango_attr_list_splice() is used to add the PangoAttrList of the preedit
string. And that is done *after* applying the PangoAttrList of the
"attributes" property.
https://bugzilla.gnome.org/show_bug.cgi?id=776868
We now have GTK_CSS_AFFECTS_CONTENT for properties that have an effect
on content rendering.
Using GTK_CSS_AFFECTS_ICON is wrong for icon-transform and icon-filter
as they don't change the icon, just how the icon is rendered, so we use
GTK_CSS_AFFECTS_CONTENT for those.
We also introduce GTK_CSS_AFFECTS_POSTEFFECT for opacity and filter -
properties that affect the whole drawing of the widget by applying an
effect after everything is said and done.
...which treats the first '.' in doc comments as the end of the summary.
So, e.g., in gtkmm, get_kinetic_scrolling() is currently summarised as
"Changes the behaviour of @scrolled_window wrt." Not very informative!
No need for a period there & anyway, the phrase "wrt to" is superfluous,
and we have space to actually say "with regard to", so just do that now.
Instead of
-gtk-icon-effect: dim;
-gtk-icon-effect: hilight;
we now use
-gtk-icon-filter: opacity(0.5);
-gtk-icon-filter: brightness(1.2);
respectively.
This node essentially implements the feColorMatrix SVG filter. I got the
idea yesterday after looking at the opacity implementation.
It can be used for opacity (not sure if we want to) and to implement a
bunch of the CSS filters.
Since the status of the GDK broadway backend is more or less unsupported,
drop the projects that build gtk4-broadwayd and gdk-broadway, and update
the projects to not to refer to them.
However, keep the Broadway configs for now as we will later transform
them to become configs for Vulkan, so bascially besides "installation"
parts and output settings, they will do the same as their Release|Debug
counterparts with no support for Broadway.
...but disable them for now. Configs will be added for the projects to
support Vulkan-enabled builds which will then enable the builds of these
sources. Extra commands and items will be needed for the GSK resources
along with ensuring GSK_RENDERER_GSK being defined for the build of GDK,
GDK-Win32 and GSK so that the builds of Vulkan-enabled builds can be done
properly.
Filter out the Vulkan sources from the 'dist hook' rules in
gsk/Makefile.am as we don't want to in turn include them twice in the
projects when the 'make dist' is performed on a system with Vulkan
builds enabled.
If the signal handler ends up changing the label text,
the link is no longer around to update the css node.
Check for this possibility to avoid a crash here.
One cannot use #if...#endif within macro calls in Visual Studio and
possibly other compilers, and there are more uses of VLAs that need to be
replaced with g_newa().
There were also checks for the clip type in gskvulkanrenderpass.c which
were possibly not done right (using the address of the type value to check
for a type value), which triggered errors as one is attempting to compare
a pointer type to an enum/int type.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
This adds support to the GDK Win32 backend so that we can support Vulkan
context creation for use in the GSK Vulkan renderer, so that we can test
it on Windows platforms as well.
https://bugzilla.gnome.org/show_bug.cgi?id=776544
Use g_newa() instead of VLAs, as VLAs may never be supported by some
compilers as it became optional in C11 and there are concerns about their
implementations in compilers that do support it.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
Forces a full redraw every frame.
This is done generically, so it's supported on every renderer.
For widget-factory first page (with the spinner spinning and progressbar
pulsing), I get these numbers per frame:
action clipped full redraw
snapshot 0ms 7-10ms
cairo rendering 0ms 10-15ms
Vulkan rendering 3-5ms 18-20ms
Vulkan expected * 0ms 1-2ms
GL rendering unsupported 55-62ms
* expected means disabling rendering of unsupported render nodes,
instead of doing fallback drawing. So it overestimates the performance,
because borders and box-shadows are disabled.
It's faster to render once for every rectangle in the clip region than
rendering the outline of the clip region.
Especially because this reduces the time necessary to build up the frame
data.
In widget-factory (where we have 3 rectangles), this leads to a 5x
speedup in the rendering time rendering alone.
Snapshotting time goes from 10ms to ~1ms, which is another huge
improvement.
Note: We interpolate premultiplied colors as per the CSS spec. This i
different from Cairo, which interpolates unpremultiplied.
So in testcases with translucent gradients, it's actually Cairo that is
wrong.
Homogeneous branches repeated the calculation/assignment of the initial
space available to children. This avoids that by shuffling some code.
Perhaps more importantly, in doing that, I ended up with some ambiguous
names, and Company and I realised how vague the pre-existing naming was.
"size" becomes "extra_space", as this is what it represents. Conversely,
"extra" becomes "size_given_to_child" (albeit still given out in two
different ways depending on whether the Box is homogeneous). My hope is
that these sections of code are now somewhat less baffling than before!
This is now tracking the clips added by the clip nodes.
If any particular node can't deal with a clip, it falls back to Cairo
rendering. But if it can, it will render it directly.
Now that every call to GtkCellArea is a snapshot call and no more cairo
calls are left, move the actual differentiation between Cairo and
Snapshot down to the cell renderer.
Little tool that creates a bunch of test files to throw add the
rendernode binary.
They should really be part of a testsuite, but we have none, so OI just
put them here.
Only keep the version that calls gsk_render_node_draw() if people
specify the --fallback option.
The actual renderer selection works just as for regular GTK. The easiest
way to influence it is setting the GSK_RENDERER environment variable.
... and implement it for the Cairo renderer.
It's an API that instructs a renderer to render to a texture.
So far this is mostly meant to be used for testing, but I could imagine
it being useful for rendering DND icons.
That code doesn't do anything.
And what the code should be doing (clearing the abckground) isn't
necessary as cairo drawing is guaranteed to clear the surface.
This does a conversion to/from GBytes and is intended for writing tests.
It's really crude but it works.
And that probably means Alex will (ab)use it for broadway.
I had originally thought I'd use GskShadow for box-shadow, but didn't in
the end.
So now it's only used for text-shadow and icon-shadow, and those don't
have a spread.
VLAs are not supported by Visual Studio and possibly other compilers that
are supported by GTK+-3.90+, and probably never will be, although it is a
C99 specification, and it became optional for C11. It is also not a part
of the newer compiler requirements that are listed out for GTK+-3.90.x.
There exist concerns about the implementation of VLAs in compilers that
support them as well, so change it to a g_newa() approach.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
Instead of a separate allocation for any arrays in the render node
we allocate these as part of the render node itself, using C99
flexible arrays.
This leads to less allocations, which is nice, but the major reason
for this is that it allows us to change the allocation scheme further
in the future. For instance, we want to do stack-like allocation so
that all the render-nodes for an entire frame are allocated in one
(or a few) chunks.
Instead of constantly recalculating this (especially recursively for
parents!) we do it only on construction, because everything is
immutable anyway. Also, most nodes had a bounds already and can
use the new parent member instead.
We also do direct access to the node bounds rather than calling
gsk_render_node_get_bounds in various places, which means
we do less copying.
This causes the snapshotting algorithm to dump all widget nodes into
their own container node. We then name that group accordingly (ie
"GtkSwitch<0xdeadbeef>") so you can easily see which node belongs where.
The feature is toggleable in the inspector's visual tab.
There's a few problems with it, becuse GtkSnapshot optimized container
nodes away if they are not needed, so we are losing some widgets...
When the first/last color stop is not at 0%/100%, we need to start the
repeating at their offsets and not at 0%/100%.
Attached reftest demonstrates the problem.
Instead of making people intiialize a rectangle and then applying border
radius manually, provide a constructor that does it for them.
While doing that, also allow people to instead request the padding box
or the content box.
Refactor all relevant code to use this new constructor.
... and make the icon rendering code use it.
This requires moving even more shadow renering code into GSK, but so be
it. At least the "shadows not implemented" warning is now gone!
The node draws a solid CSS border, which can be used to cover everything
but dashed and dotted borders (double, groove, inset, ...).
For different border styles, we overlay multiple nodes and set their
colors to transparent for sides with non-matching styles.
This way we can pass the command pool around.
And that allows us to allocate and submitcustom buffers.
And that is necessary to make staging images work.
It turns out, some simple getters - such as
gdk_drawing_context_get_clip() - love copying things before returning
them.
I guess somebody has to burn cycles...
When the background-clip of the background is smaller than the
background-clip of blended images, not pushing a group is wrong.
Test testing exactly that included.
This uses the new push()/pop() mechanism to its fullest extent when
implementing transitions. It's fun to inspect the results in the
inspector.
Crossfades don't work yet, they continue using a Cairo fallback.
A side effect of the stack conversion is that widget-factory now uses
snapshots for a lot more things.
It is now possible to call push() subfunctions for simple container
nodes with just a single child. So you can for example
gtk_snapshot_push_clip() a clip region that all the nodes that get
appended later will then obey.
gtk_snapshot_pop() will then not return a container node, but a clip
node containing the container node (and similar for the transform
example).
This is implemented internally by providing a "collect function" when
pushing that is called when popping to collects all the accumulated
nodes and combine them into the single node that gets returned.
To simplify things even more, gtk_snapshot_pop_and_append() has been
added, which pops the currently pushed node and appends it to the
parent.
The icon rendering code has been converted to this approach.
This code makes renderers fall back to Cairo rendering if they don't
know how to handle a render node's type.
This allows adding new render nodes with impunity.
Instead of appending a container node and adding the nodes to it as they
come in, we now collect the nodes until gtk_snapshot_pop() is called and
then hand them out in a container node.
The caller of gtk_snapshot_push() is then responsible for doing whatever
he wants with the created node.
Another addigion is the keep_coordinates flag to gtk_snapshot_push()
which allows callers to keep the current offset and clip region or
discard it. Discarding is useful when doing transforms, keeping it is
useful when inserting effect nodes (like the ones I'm about to add).
Instead of having a setter for the transform, have a GskTransformNode.
Most of the oprations that GTK does do not require a transform, so it
doesn't make sense to have it as a primary attribute.
Also, changing the transform requires updating the uniforms of the GL
renderer, so we're happy if we can avoid that.
I'm about to move children handling to the container node, which means
the generic code can no longer assume children APIs existing.
So rewrite the treemodel to work without it.
gsk_render_node_get_bounds() still exists and is computed via vfunc
call:
- containers dynamically compute the bounds from their children
- surface and texture nodes get bounds passed on construction
In the brave new world of refactored render nodes, this function doesn't
really make any sense anymore. We could turn it into a vfunc, but I
don't think it's useful.
Especially because even in the brave old world, this function was
causing a vastl overallocation of nodes when the GL renderer needed render
targets.
If we ever feel, we need this function again, we can readd it later.
But nobody is using it other than for overriding opactiy. And you can
just override opacity directly if you care.
Creating render nodes is fire-and-forget, so all one should do is create
a container, append, append, append and then send it off to the
renderer. So there's no need to replace, insert between or anything
else.
We want to split nodes into containers and nodes that do actual drawing.
So pushing nodes that do drawing is exactly the wrong thing.
Also fix up GtkPopover. There's no need for it to push anything.
When we generate the Visual Studio 2013 projects, we need to remove the
*.vs12.sourcefiles and *.vs12.sourcefile.filters that are generated during
the process, so that 'make distcheck' won't complain about leftover files.
When running uninstalled tests with GtkApplication on an autobuilder with
a fake session bus, warnings will cause the tests to abort. The GNOME
session manager, the Xfce session manager, and the Inhibit portal are all
not needed for normal operation of GTK, so we should not log warnings if
they are not found.
As well as not being present on a fake session bus, it's also not
expected that they'll be present on all platforms.
https://bugzilla.gnome.org/show_bug.cgi?id=774784
... with gtk_list_box_get_row_at_y. It would be nice to avoid the
'find' versus 'get' discrepancy since we are planning to expose it as
public API.

Fix the build after the branch wip/alexl/simplify-gdkwindow was merged, as
there are some changes that broke things in the Windows backend, namely:
-gdk_win32_input_shape_combine_region() should not be removed at this
point (though it is a stub--otherwise GDK/Win32 will crash)
-Some more code need to be removed due to the removal of items in the
above-mentioned merged branch
Also, like the X11 backend, do not allow the creation of native child
windows, and stop checking for subsequent child windows
(GDK_WINDOW_CHILD), so that we can clean things up a bit.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
It does weird clipping that
(a) nobody likes
(b) is hard to support in the new rendering world.
So we take the easy way out.
The actual frame is now drawn by the frame node around the label.
GtkCellView has a gadget, so peopl can do all their shenanigans with
CSS.
And the original use case (overriding the background so that the
cellview's GdkWindow shares the background color of the combobox) is
outdated since we have transparent backgrounds.
We're not currently using this, and dropping it allows us to loose
a bunch of code which leads us towards the goal of having GdkWindow
only for toplevels (and reparenting makes not sense for toplevels).
We can't really support these on e.g. wayland anyway, and we're trying
to get rid of subwindow at totally in the long term, so lets drop this.
It allows us to drop a lot of complexity.
For subsurfaces, the new state which includes the input shape is not
applied by the compositor if the subsurface is in effective synchronous
mode.
So we need to apply the input shape once parent surface is in effective
desynchronized mode, which is when it's committed, otherwise the input
shape may never be applied if the widget is not using being_paint() /
end_paint() to draw on its subsurface, like clutter does.
We do that only for empty input shape as those won't need update when
the subsurface is resized, for all other non-empty input shape, the
client still has to use begin_paint()/end_paint() for the input shape to
be applied.
https://bugzilla.gnome.org/show_bug.cgi?id=774534
It's using a GtkCssPositionValue, even though that name is wrong. But
the functionality of managing 2 lengths is exactly what we want.
Nobody is using this yet.
- Recognize "gl" as well as "opengl" for the GL renderer
- GSK_RENDERER=help now works
- g_warning() for an unrecognized renderer (typo detection!)
- g_print() the actual renderer that is used (and error messages when
selecting) when a GSK_RENDERER is given, so you'll notice if your
renderer isn't taken.
Previously, code would work fine with --disable-vulkan if the Vulkan
headers were installed - code would happily just use them as they're
installed in /usr/include.
By creating unlimited render objects, we would never wait on the GPU.
This would mean that if the GPU was the bottleneck, we would fill its
queue with render commands faster than it could process them.
And because the nvidia binary driver and my code work surprisingly well
and bugfree, this lead to exhaustion of RAM. I had 50GB of swap
configured and my hard disk was quicker as swap storage than my GPU was
at processing the commands, so stuff still filled up.
At that point my computer became rather unresponsive and I decided to
reboot it, so I that could write this patch.
Add SURFACE and TEXTURE operations. This way, we actually render more
than one node every frame because not everything is a fallback node
anymore that gets composited with its children into a cairo surface.
Instead of pushing the root matrix, push the world matrix for the
current node. That way, the bounds we emit as vertices are actually
properly transformed.
First, we collect all the info about descriptor sets into a hash table,
then we use its size to determine the amount of sets and allocate those
before we finally go ahead and use the hash table's contents to
initialize the descriptor sets.
And then we're ready to render.
We can let the GPU do its stuff without waiting. The GPU knows what it's
doing.
Which means we now get a lot of time to spend on doing CPU things (read:
we're way better in benchmarks).
The old behavior is safer, so we want to keep it around for debugging.
It can be reenabled with GSK_RENDERING_MODE=sync.
And move the actual rendering code there.
A RenderPass is a collection of operations on the same target that
get executed one after another. It roughly targets VkRenderPass or
rather the subpasses of a VkRenderPass.
For now, only the infrastructure is there. No real stuff is happening.
This is refactoring work.
GskVulkanRender is supposed to be the global object for a render
operation, ie GskVulkanRenderer.render() will create this object for
what it does.
The object will be split into stages that perform the operations
necessary to create a drawing.
Instead of using a staging iamge, we require the final image to be
linearly allocated and have host-visible memory.
This improves performance quite a bit.
The old code is still there and can be enabled with a simple change
to a #define in gskvulkanimage.h
Instead, complain if somebody calls gdk_x11_window_get_xid() on a
non-native window.
We cannot make random windows native anymore because there's no GSK
renderer associated with them, so we cannot draw them.
We can now upload vertices.
And we use this to draw a yellow background. Which is clearly superior
to not drawing anything.
Also, we have shaders now. If you modify them, you need glslc installed
so they can be recompiled into Spir-V bytecode.
1. Output Vulkan status in summary
2. Add missing "test" call
3. Check for glslc
The glslc check will be necessary later for the code that automatically
compiles the Vulkan glsl source to Spir-V.
Nothing happens if glslc is not available - unless you modify the glsl.
gdk_window_create_vulkan_context() now exists and will return a Vulkan
context for the given window. It even initializes the surface. But it
doesn't do anything useful yet.
Adds the gdk_display_ref_vulkan() and gdk_display_unref_vulkan()
functions which setup/tear down VUlkan support for the display.
Nothing is using those functions yet.
These only exist for the window dragging which does not exist anymore
currently. It will be reintroduced later in a form that does not require
these handlers.
I read the code as if (use_gl) instead of if (!use_gl) and commented it
out in bddfd7bb41. That broke drawing on
Wayland without OpenGL completely.
Whoops.
Now it's back.
There were some parts that need some updates after the refactoring in
GDKGL, so that the code will continue to build and run.
For gdkwindow-win32.c, comment out the parts where we check for use_gl
(which was removed), since we are going to move all drawing to OpenGL,
but don't remove/disable the whole portion as that transition is not
complete at this point.
There a is new GDKGL function that checks for the damaged area of the back
buffer, but since the notion of "damage" is for *NIX (GLX/EGL for
Wayland/mir), meaning that there is no such extension for Windows in this
regard, so we can't support this on Windows as-is, at least for now.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
This is a way to query the damaged area of the backbuffer.
The GL renderer uses this to compute the extents of that damage region
(computed via buffer age) and use them to minimize the area to redraw.
This changes the semantics of GL rendering to "When calling
gdk_window_begin_frame() with a GL context, the area by
gdk_gl_context_get_damage() needs to be redrawn and every other pixel of
the backbuffer is guaranteed to be correct.
After gdk_window_end_frame() on a GL-drawn window, the whole backbuffer
must be correct.
We can always glXBufferSwap() now because of this.
... instead of a gl context.
This requires some refactoring in the way we mark the shared context as
drawing: We now call begin_frame/end_frame() on it and ignore the call
on the main context.
Unfortunately we need to do this check in all vfuncs, which sucks. But I
haven't found a better way.
That way we can capture both the actual changes (clip region) and the
area that was redrawn (render region), which in OpenGL might not be
identical.
Nothing shows the render region yet though...
Reenable GL drawing, but do it without Cairo.
Now, the context passed to gdk_window_begin_draw_frame() decides how
drawing is going to happen. If it is NULL, Cairo is used like before.
If a context is passed, Cairo may not be used for drawing and
gdk_drawing_context_get_cairo_context() is going to return NULL.
Instead, the GL renderer must draw to the GL backbuffer and
end_draw_frame() is then swapping that to the front.
The GskGLRenderer has lost the texture it used to render to and adapted
to render directly to the backbuffer instead.
The only thing missing is for GtkGLArea to gain back a performant way to
render. But it didn't have one since the introduction of GSK, this
patchset doesn't change anything about it.
The new rendering avoids two indirections (the GSK renderer's texture
and the GDK double buffering surface).
It improves icon count in the fishbowl demo by 30%.
This way, we can query the GL context's state via
gdk_gl_context_is_drawing().
Use this function to make GL contexts as attached and grant them access
to the front/backbuffer for rendering.
All of this is still unused because GL drawing is still disabled.
No visible changes as GL rendering is disabled at the moment.
What was done:
1. Move window->invalidate_for_new_frame to glcontext->begin_frame
This moves the code to where it is used (the GLContext) and prepares it
for being called where it is used when actually beginning to draw the
frame.
2. Get rid of buffer-age usage
We want to let the application render directly to the backbuffer.
Because of that, we cannot make any assumptions about the contents the
application renders outside the clip area.
In particular GskGLRenderer renders random stuff there but not actual
contents.
3. Pass the actual GL context
Previously, we passed the shared context to end_frame, now we pass the
actual GL context that the application uses for rendering. This is so
that the vfuncs could prepare the actual contexts for rendering (they
don't currently).
4. Simplify the code
The previous code set up the final drawing method in begin_frame.
Instead, we now just ensure the clip area is something we can render
and decide on the actual method in end_frame.
This is both more robust (we can change the clip area in between if we
want to) and less code.
This is a temporary switch-off of the GL dawing code that will make
things keep running. All GL related code (like the GSK renderer or
GtkGLArea will now fall back to software.
Wayland subsurfaces can have other native window parents, but those need

GtkListBox is not a windowed widget anymore so we can't use
gtk_widget_get_window. Just directly access priv->view_window instead to
get the right window.
For a menu mode CB with wrap_width == 0 and an active item, that item is
selected in gtk_combo_box_menu_popup. Selection causes the MenuShell to
activate and hence take a grab. This was done before the menu was popped
up. A patch distributed in Debian sid - after being proposed on our BZ -
revealed that on the 1st popup of any such ComboBox, within grab_add,
the MenuShell's toplevel's GdkWindow is NULL. This causes a Gdk-CRITICAL
assertion fail on the 1st time opening any such CB, on Debian and if
that patch were merged to GTK+. By selecting after popup, we ensure the
MenuShell is realised before its grab_add and so avoid the critical.

This way, we don't spam criticals when GL is not available. Instead, we

The functions gdk_pixbuf_get_from_window() and
gdk_cairo_set_source_window() are unreliable and depend on the windowing
system (they work great on X11 and Win32, less so on Quartz and Wayland).
With the switch to new drawing API and OpenGL, we can definitely no
longer support a generic way to snapshot windows.
People should either write windowsystem-specific code or draw their
widgets directly - like with gtk_widget_draw() - if they need to get a
rendering.
The tests read a nonexisting colorprofile, try to convert stuff read
from the window into it, do things that gdk-pixbuf should test and
then aren't even integrated into the testuite.
Sheesh.

This can be triggered on workspace switches, and on hidpi results in

Just to avoid having to do NULL checks when calling
widget_class->snapshot. We were crashing with drawing areas who don't
have a draw or a snapshot vfunc (woot!).
We need so subtract the allocation from the clip to get the clip offset,
not the other way around.
This was screwing in particular with marks on GtkScale, because GtkScale
mark clip computation is broken and always returns (0,0) which makes
scales have a waaaaay too large clip.
But that's another bug.
And use this to cull widgets and gadgets that are completely outside the
clip region.
A potential optimization is to apply this clip region to cairo contexts
created with gtk_snapshot_append_cairo_node(), but for that we'd need to
apply the inverse matrix to the clip region, and that causes rounding
errors.
Plus, I hope that cairo drawing becomes exceedingly rare so it won't be
used for the whole widget factory like today (which might also explain
why no culling happens in the widget factory outside the header bar.
The equivalent to cairo_matrix_multiply (a, b, c) is
graphene_matrix_multiply (c, b, a).
graphene_matrix_multiply (a, b, c) may not be called with b and c being
the same matrix.
Grips have long been unused in GTK, so remove all support for them.
This removes the GTK_STYLE_CLASS_GRIP and the special
gtk_render_handle() code for drawing those grips.
This allows renderers (or anyone really) to attach "render data" to
textures. Only the first render data sticks.
You can gsk_texture_set_render_data() with the key you will use to
look the data up again, and if no data has been set yet, yours will be
set.
You can retrieve this data via gsk_texture_get_render_data() later on.
If your data has been cleared, NULL will be returned.
When gsk_texture_clear_render_data() is called (which the texture will
call when it is finalized), your destory notify will be called and you
have to release your render data.
The GL driver uses this to attach texture ids to GskTextures.
We do no longer bind textures to a renderer, instead they are a way for
applications to provide texture data.
For now, that's it. We've reverted to uploading it from scratch every
frame.
The snapshot vfuncs must only append at most a single node,
otherwise things are going to break if the widget is the root node.
Unfortunately there is no code that can check this in a generic fashion,
so we'll have to debug this on a case-by-case basis.
This happens in regular code paths for example when trying to render the
empty text string. We don't want to store a surface on the render
node in such a case (so actual rendering isn't slowed down), but we do
want to return a working cairo context that is not in an error state
(so the cairo rendering can continue without error messages).
We want to unrealize the renderer only after all widgets have been
unrealized. Otherwise, the widgets cannot release rendering resources
like textures.
Note that this implementation does not respect GDK windows at all. If
your widget requires respecting them, you should write your own
snapshot implementation and not chain up.
We now look at which of get_render_mode, draw or snapshot vfuncs is the
latest to have been overwritten in the class tree and then use that one.
This allows GtkContainerClass and GtkBinClass to override all of them
for without screwing things up.
and gtk_snapshot_render_frame() to be direct replacements for the
old gtk_render_*() functions.
Use them to replace Cairo usage completely in gtk_window_snapshot().
We now try to emulate cairo_t:
We keep a stack of nodes via push/pop and a transform matrix.
So whenever a new node is added to the snapshot, we transform it
by the current transform matrix and append it to the current node.
Unlike other container widgets, GtkStack would allocate its children
prior to moving its windows, which might prevent further valid size
allocation signals to be emitted.
Re-order the size allocation of child widgets to be performed after
moving the GtkStack windows.

We are currently truncating job names to 255 bytes, because that's the
maximum allowed length of job-name attribute in CUPS. This is a CUPS
limitation that GtkPrintOperation shouldn't need to know, and it
shouldn't affect other backends, that might have other limitations or
even no limitation at all. This has another side effect, that what you
set as GtkPrintOperation:job-name could be different to what you get if
the property is truncated, this is not documented in
gtk_print_operation_set_job_name(). So, I think the job name should be
truncated by the CUPS backend, right before setting the job-name
attribute.

The GApplication platform data may contain a startup ID that on X11

For wayland clients, the startup notification ID is currently only set
from the DESKTOP_STARTUP_ID environment variable. As that variable is
only set for clients launched via exec(), startup completion is not
indicated correctly for DBus-activated applications unless an explicit

uses gdk_notify_startup_complete().

This enables HiDPI support for GTK+ on Windows, so that the
fonts and window look better on HiDPI displays. Notes for the current
work:
-The DPI awareness enabling can be disabled if and only if an application
manifest is not embedded in the app to enable DPI awareness AND a user
compatibility setting is not set to limit DPI awareness for the app, via
the envvar GDK_WIN32_DISABLE_HIDPI. The app manifest/user setting for
DPI awareness will always win against the envvar, and so the HiDPI items
will be always setup in such scenarios, unless DPI awareness is disabled.
-Both automatic detection for the scaling factor and setting the scale
factor using the GDK_SCALE envvar are supported, where the envvar takes
precedence, which will therefore disable automatic scaling when
resolution changes.
-We now default to a per-system DPI awareness model, which means that we
do not handle WM_DPICHANGED, unless one sets the
GDK_WIN32_PER_MONITOR_HIDPI envvar, where notes for it are in the
following point.
-Automatic scaling during WM_DISPLAYCHANGE is handled (DPI setting change of
current monitor) is now supported. WM_DPICHANGED is handled as well,
except that the window positioning during the change of scaling still
needs to be refined, a change in GDK itself may be required for this.
-I am unable to test the wintab items because I don't have such devices
around.

Now that GTK+ is built as a single DLL, and the .lib that is built is
gtk-4.lib, we need to update the autotools sections in generating the
NMake Makefile snippets so that we can have the correct commands and flags
for building the .gir files, which will all now link to gtk-4-vsXX.dll (or
so).
As with the autotools builds, use gtk-4 as the name of the .lib file that
is produced from the build.
Actually this is already done with GTK-3.x with the autotools builds,
but this update is not done there as gtk-3.0.lib/gdk-3.0.lib/gailutil-3.0.lib
was used for such a long time that changing it there might have caused
trouble for people there.
Update the project configs to build GDK/GSK as a static lib and include
them into the GTK+ DLL as a monolithic DLL, which is in line with what is
done in the autotools builds, since the code changes needed for Windows
builds for a monolithic build are now in place.
Now that the autotools build folded the GDK/GSK bits into the main GTK+
DLL, there are some updates that need to be done for this. We need to:
-Fold the DllMain() of GDK-Win32 into the main GTK+ DllMain(), as we need
the HINSTANCE to register the window. We can't have two DllMain()'s in a
single DLL.
-Remove the GDK rc(.in) files, as that is not used anymore. Make the GTK+
.rc(.in) file load the gtk.ico GTK+ logo file instead so that we still
get the GTK+ logo for the application icon by default. Update the
autotools build files as well.
-Revert commit b9f9980 as LRN pointed out in comment 25 in bug 773299, as
GTK+ is now a monolithic DLL, and we ought not to export this private

This is a problematic struct, and giving direct access to it
has kept us from making improvements to GtkTextView. Drop it
from the public API, together with the auxiliary APIs. If
it turns out that this functionality is needed, we should add
individual getters.
We now record all render operations and display them.
Warning: This is very brute force, you can't clear the recordings or
turn recording off. And this thing easily records 25MB per recorded
frame, so be careful to not run out of memory and get your browser
killed. ;)
This one introduces the Recording object which is essentially a single
instance of something that happened.
The RenderRecording is an instance of an actual rendering operation.
The GLSL versions are:
OpenGL 2.1: #version 110
OpenGL 3.0: #version 130
OpenGL 3.2: #version 150
OpenGLES 2.0: #version 100
OpenGLES 3.0: #version 300 es
So we need to check the version of the GdkGLContext if we want use the
appropriate version, especially for legacy OpenGL contexts, which can be
both 3.x and 2.x.
This ensures that the drawing does not extend the actually drawn area.
It also ensures that our math is sane, because the math assumes the clip
area cannot extend the window. After all, before GTK4 it always was like
that.
Fixes a bunch of drawing bugs when the clip area does indeed extend too
far.
We want to have the coordinate system of the created cairo surface to be
identical to the coordinate system of the node's bounds. For that, we
need to translate the cairo surface by the bounds' origin.
In that case, we can't just rely on the stack allocation being big
enough. Especially, the child can actually be bigger than the current
stack allocation, so take that into account when positioning it.
The typical UI file has a lot more <property> tags than it has
<requested> or <interface> tags, etc. so order the string comparisons
according to this expected case.
We need an overridable entry point for GskRenderer to create Cairo
surfaces.
Implementations of GskRenderer can override create_cairo_surface() to
create efficient surfaces, possibly with zero copies involved, depending
on the GDK backend.
Switch code to use gdk_display_is_composited() instead.
The new code also doesn't use a vfunc to query the property but rather
requires the backend to call set_composited()/set_rgba() to change the
value.
Also add properties for those two properties.
The first property is equivalent to checking if an RGBA visual exists,
the 2nd is equivalent to gdk_screen_is_composited().
This reverts commit 8e29222d95.
This needs more work - spin buttons need to be converted at
the same time, and we should make sure that text still appears.
Update the GDKGL implementation:
-Allow legacy contexts to be created.

which also adds support for anti-aliasing
In fact the changes here are required for GTKGL to work properly on

Note that creation of gles contexts is not done here, as the system does
not support such contexts directly on Windows, but only through means such
as ANGLE, which is a totally different issue here.

Add the needed custom build steps to generate the GResource and
enumeration sources that is needed for the build, and make sure that the

This follows what happens in the autotools builds.
Also fix some project namespaces and the install project where there is a typo
in a project dep, which may cause a problem during the build.
Includes the ability to turn on updates in the inspector. Animations are
now run via a tick function which allows us to neatly overlay a
semi-transparent red rectangle and fade it out over time.
It also probably enables way more, but somebody with more UI neatness
than me needs to figure out what it eanbles first...
Before, we would immediately invalidate the GdkWindow of the widget, now
we call the parent's GtkWidgetClass.queue_draw_child() function.
This allows the parent to track redraw queueing of children.
By default GtkWidgetClass.queue_draw_child() will again chain up to its
parent while respecting the GdkWindow hierarchy for clipping.
GtkWindow is then the only widget actually invalidating the GdkWindow.
This essentially moves redraw queueing from GDK to GTK.
For some reason we end up allocating the colorplane widget
before it is realized, and then never initialize the surface.
Fix this by explicitly doing it on realize.

This adds the initial MSVC build items needed to build GSK under Visual Studio,

-The NMake snippets to build the introspection files for GSK.
-The .bat files to call glib-mkenums to generate the enumeration sources.
We now need C99 features from the compiler which are only supported by
Visual Studio 2013 and later, so drop the MSVC 2008~2012 projects, and make
the baseline supported Visual Studio version be 2013. Update the build files
as a result.
GTK+-3.89.0 and later will require C99 features that is only supported on
Visual Studio 2013 and later, so prepare build/Makefile.msvcproj for this.
We still keep the 2008~2010 stuff here as this strives to be a shared module,
and there are projects using this that still supports building on pre-2013
Visual Studio.
These complicate a lot of GdkWindow internals to implement features
that not a lot of apps use, and will be better achieved using gsk.
So, we just drop it all.

Now that the use_es field is an int with a possible negative value, we

will be fixed to 3.0. If that happens, we need to set the legacy bit on
the GdkGLContext, since that bit will be used to determine the version
and type of GLSL shaders that will be used by application and toolkit
code alike.
With best-effort, try to use gdk_window_move_to_rect() more often, when
all pieces fit together. For the non-legacy paths to be triggered for
when gtk_menu_popup_for_device() or gtk_menu_popup() were used, the
following conditions must be met:
1) There is no custom positioning function specified
2) The menu is attached to a widget (using gtk_menu_attach_to_widget())
3) There is a associated grab device
https://bugzilla.gnome.org/show_bug.cgi?id=772922
xdg_shell v6 allows grabless popups, whose behavior is not that
different from override redirect windows with no grab to take
keyboard input (and pointer events outside).
This means we can relax the requirement to have a grab before
creating an xdg_popup. The warning is still useful to have so
people stop relying on gdk_window_show();gdk_device_grab() being
an ok pattern to popup a window, it's been moved to wayland
implementation of gdk_device_grab() instead, so we warn if trying
to grab a GDK_WINDOW_TEMP window that's already visible.

Newer versions of Automake warn about forward compatibility when the
build uses sources in sub-directories without the subdir-objects option.
Both GTK+ and GDK have an almost-but-not-quite non-recursive Automake
layout, with sources in sub-directories contributing to the build of a
top-level object.
In theory, just adding subdir-objects to AM_INIT_AUTOMAKE would be
enough, but the test suite references sources in a different top-level
in order to build tests that verify the implementation of private data
structures. This is not really allowed when using subdir-objects and out
of srcdir builds. In order to fix this case, we require some ad hoc
rules to create symbolic links in the appropriate build directory.
the darker bottom border used on buttons looks bad on circular ones
so now a gradient clipped on the border-box and a transparent
border is used in that partcular case.
See https://bugzilla.gnome.org/show_bug.cgi?id=771205 for details.
$button_fill contains the background-image property value of
buttons, having it readable outside the drawing mixin allows, for
example, stacking background images in an easier way.
This updates all the projects files to be be named appropriately as we move from GTK-3.x to 4.x,
and updates the autotools files so that things are distributed and generated properly.
Also remove deprecated/gtkstatusicon-quartz.c from gtk/Makefile.am, as that was causing 'make dist'
to fail as that file has been removed.
This fixes 'make dist' with the updated existing project files in proper order.
Note that this does not include the new GSK, which will be added later, so the project files do
not yet build the whole stack on Visual Studio at this point.
Make the Makefile.am targets for generating the Visual Studio projects re-generate the
project files and the header listings whenever the Makefile.am's that include
build/Makefile.msvcproj changes, so that whenever a source/header is added, they will
be reflected in the projects and in the property sheets that are used to copy the
headers.
Also ensure that these are applied to the vs11, vs12 and vs14 projects when this
happens, as they are copied and processed from the Visual Studio 2010 projects.
While porting GTK to GskRenderer we noticed that the current fallback
code for widgets using Cairo to draw is not enough to cover all the
possible cases.
For instance, if a container widget still uses GtkWidget::draw to render
its children, and at least one of them has been ported to using render
nodes instead, the container won't know how to draw it.
For this reason we want to provide to layers above GSK the ability to
create a "fallback" renderer instance, created using a "parent"
GskRenderer instance, but using a Cairo context as the rendering target
instead of a GdkDrawingContext.
GTK will use this inside the gtk_widget_draw() implementation, if a
widget implements GtkWidgetClass.get_render_node().
We're going to need to allow rendering on a specific cairo_t in order to
implement fallback code paths inside GTK; this means that there will be
times when we have a transient GskRenderer instance that does not have a
GdkDrawingContext to draw on.
Instead of adding a new render() implementation for those cases and then
decide which one to use, we can remove the drawing context argument from
the virtual function itself, and allow using a NULL GdkDrawingContext
when calling gsk_renderer_render(). A later commit will add a generic
function to create a transient GskRenderer with a cairo_t attached to
it.
Renderers inside GSK will have to check whether we have access to a
GdkDrawingContext, in which case we're going to use it; or if we have
access to a cairo_t and a window.
GskRenderNode is, at its core, a write-only API; you're supposed to set
up the render nodes instead of querying them for state.
Querying render nodes is left to the GskRenderer implementation.
Add a should_propagate function for render nodes. Eventually,
this is meant to avoid creating render nodes for child widgets
that are outside the parents clip area. Since we don't have
that information available right now, just filter out nondrawable
children for now.
Change get_render_node to return nodes that are sized to the clip
area and expect to be placed at the clip position; change
gtk_container_propagate_render_node to place child render nodes
accordingly, and change gtk_css_gadget_get_render_node to return
nodes that are sized accordingly as well.
We store the vertices in (unscaled) window coords (but the item size
is still scaled to match the texture size). Also, the
projection/model-view multiplication order is switched so that the scale
is applied at the right place.
The renderer will always use nearest-neighbor filters because it renders
at 1:1 pixel to texel ratio.
On the other hand, render nodes may be scaled, so we need to offer a way
to control the minification and magnification filters.
If we already have a GL texture we definitely don't want to use
gdk_cairo_draw_from_gl() to draw on a Cairo context if we're going
to take the Cairo surface to which we draw and put it into an OpenGL
texture.
The details of the modelview and projection matrices are only useful for
the GL renderer; there's really no point in having those details
available in the generic API — especially as the Cairo fallback renderer
cannot really set up a complex modelview or a projection matrix.
Instead of using the background as the gadget's node, we add a
non-drawing node that can be used to apply offsets; all other nodes are
children of the "box" node.
Just like we reuse texture ids with the same size we can, at the expense
of a little memory, reuse vertex buffers if they reference the same
attributes and contain the same data.
Each VAO is marked as free at the end of the frame, and if it's not
reused in the following frame, it gets dropped.
The child-transform is useful only if we also provide clipping to the
parent nodes, otherwise children will just be drawn outside of the
parent's bounds.
We'll introduce child transforms either at a higher layer, or once we
add clipping support to GskRenderNode.
This is the first example of indirect rendering involving
a box gadget. For now, we iterate the child gadgets manually,
and rely on gtk_container_propagate_render_node for the
child widgets. Eventually, we may want a better solution
here.
...and implement it for GtkCssGadget and GtkCssCustomGadget.
This allows us to decide on a per-object basis if a custom
gadget needs a render node for content or not.
The custom gadget draw function has the side effect of informing
the gadget machinery wether to draw focus or not. Bring the
draw function back, just for its boolean return value. We may
want to find a better solution for this.
I don't think this should stay in the code long-term, but it
is useful for debugging. It helped me track down some suspicious
placements of render nodes.
Give all nodes the same detail about the owner widget.
This reveals that every GtkCssCustomGadget gets a
DrawGadgetContents node, even if their draw_func is NULL.
We may want to come up with a better solution for that.
When creating the GskRenderNodes for the gadgets we should not translate
the coordinates inside the Cairo context, but we should tweak the
coordinates of the anchor point.
This is still not enough to get an appropriate rendering, as the result
is still slightly offset to the left.
Instead of passing the size of the buffer, we should pass the number of
quads; we know what the size of a single quad structure is, so we can do
the multiplication internally when creating the VAO.
This allows us to print the quads for debugging purposes.
GtkWidget.create_render_node() sets up a GskRenderNode appropriate for
rendering the contents of a widget, including its bounds,
transformation, and anchor point.
The naming is consistent with other scene graph libraries, as it
represents an additional translation transformation applied on top of
the provided transformation matrices.
We can also simplify the implementation by applying the translation when
we compute the world matrix.
We keep the textures used inside a frame around until the end of the
following frame; whenever we need a texture with the same size, and
it's not marked in use, then we just reuse the existing texture.
We were allocating a surface thats big enough for the clip, and
we were setting the transform for that, but then GtkContainer
was overriding the transform with the one for the allocation.
Also, we were drawing at the clip position, not the allocation
position.
This was overwhelming other useful debug output, so make it
opt-in. We print the render items for both opengl and transforms,
since the matrices bleed into each other, otherwise.
Since we use an FBO to render the contents of the render node tree, the
coordinate space is going to be flipped in GL. We can undo the flip by
using an appropriate projection matrix, instead of changing the sampling
coordinates in the shaders and updating all our coordinates at render
time.
We need to apply a scaling factor whenever we deal with user-supplied
coordinates, like:
- when creating textures
- when setting up the viewport
- when submitting the scene
Render nodes need access to rendering information like scaling factors.
If we keep render nodes separate from renderers until we submit a nodes
tree for rendering we're going to have to duplicate all that information
in a way that makes the API more complicated and fuzzier on its
semantics.
By having GskRenderer create GskRenderNode instances we can tie nodes
and renderers together; since higher layers will also have access to
the renderer instance, this does not add any burden to callers.
Additionally, if memory measurements indicate that we are spending too
much time in the allocation of new render nodes, we can now easily
implement a free-list or a renderer-specific allocator without breaking
the API.
We cannot implement GtkWidgetClass.get_render_node() in GtkContainer
without breaking the fallback path that renders a widget to a single
render node rasterization. For GtkContainer subclasses we should provide
a simple API, similar to gtk_container_propagate_draw(), that gathers
all the render nodes for each child.
If a node is non-opaque and has a non-zero opacity we need to paint its
contents and children first to an off screen buffer, and then render the
resulting texture at the desired opacity — otherwise the opacities will
combine and result in the wrong rendering.
We're not going to use separate rendering lists soon, and the way we
render items is less similar to a gaming engine and more similar to a
simpler compositor. This means we don't need to perform a two pass
rendering — opaque items first, transparent items later.
Use appropriate names, and annotate the names with the types — 'u' for
uniforms, 'a' for attributes. The common preambles for shaders are split
from the bodies, so we need some way to distinguish the uniforms and the
attributes just from their name.
We want the GL driver to cache as many resources as possible, so we can
always ensure that we're in a consistent state, and we can handle state
transitions more appropriately.
Drop the texture parameters handling from the texture creation, and
associate them with the contents upload. Also, rename the function to
something more in line with what it does.
We want to add the list of FBOs tied to a texture; this means we cannot
trivally copy the Texture structure when adding it to a GArray. We're
also going to have more textures than VAOs, so it makes more sense to
use a O(1) access data structure for them.
We can use the GL_ARB_timer_query extension (available since OpenGL
3.2, and part of the OpenGL specification since version 3.3) to query
the time elapsed when drawing each frame. This allows us to gather
timing information on our use of the GPU.
The clip rectangle may have non-zero offsets, so we need to ensure that
the GskRenderNode associated to the rendered area is translated by those
same offsets.
For the root node we do not need to use blending, as it does not have
any backdrop to blend into. We can use a simpler 'blit' program that
only takes the content of the source and fills the texture quad with
it.
We should use ShaderBuilder to create and store programs for the GL
renderer. This allows us to simplify the creation of programs (by moving
the compilation phase into the ShaderBuilder::create_program() method),
and move towards the ability to create multiple programs and just keep a
reference to the program id.
We should keep the ShaderBuilder around and use it to query the various
uniform and attribute locations when needed, instead of storing those
offsets into the Renderer instance, and copying them. This allows a bit
more flexibility, once we have more than one program built into the
renderer.
The GL renderer should build the GLSL shaders using GskShaderBuilder.
This allows us to separate the common parts into separate files, and
assemble them as necessary, instead of shipping one big shader per type
of GL API (GL3, GL legacy, and GLES).
GskShaderBuilder is an ancillary, private type that deals with the
internals of taking GLSL shaders from resources and building them,
with the additional feature of being able to compose shaders from a
common preamble, as well as adding conditional defines (useful for
enabling debugging code in the shaders themselves).
Using GObject as the base type for a transient tree may prove to be too
intensive, especially when creating a lot of node instances. Since we
don't need properties or signals, and we don't need complex destruction
semantics, we can use GTypeInstance directly as the base type for
GskRenderNode.
We need a virtual function to retrieve the GskRenderNode for each
widget, which is supposed to attach its own children's GskRenderNodes.
Additionally, we want to maintain the existing GtkWidget::draw mechanism
for widgets that do not implement get_render_node() — as well as widgets
that have handlers connected to the ::draw signal.
This commit changes the way GskRenderer and GskRenderNode interact and
are meant to be used.
GskRenderNode should represent a transient tree of rendering nodes,
which are submitted to the GskRenderer at render time; this allows the
renderer to take ownership of the render tree. Once the toolkit and
application code have finished assembling it, the render tree ownership
is transferred to the renderer.
Whenever the render tree changes we want to drop the RenderItem arrays,
as each item contains a pointer to the GskRenderNode which becomes
dangling once the root node changed.
The surface-to-GL upload logic has become more complicated with the
addition of the GLES code paths; it's more logical to have a public
utility function that can be called from GDK users, instead of copy
pasting the whole thing multiple times.
GSK is conceptually split into two scene graphs:
* a simple rendering tree of operations
* a complex set of logical layers
The latter is built on the former, and adds convenience and high level
API for application developers.
The lower layer, though, is what gets transformed into the rendering
pipeline, as it's simple and thus can be transformed into appropriate
rendering commands with minimal state changes.
The lower layer is also suitable for reuse from more complex higher
layers, like the CSS machinery in GTK, without necessarily port those
layers to the GSK high level API.
This lower layer is based on GskRenderNode instances, which represent
the tree of rendering operations; and a GskRenderer instance, which
takes the render nodes and submits them (after potentially reordering
and transforming them to a more appropriate representation) to the
underlying graphic system.
This is an attempt to get rid of gdk_window_new() for more specific use
cases. These 2 are for client-side windows - regular ones and input-only
ones resepectively.
So far all those functions just call into gdk_window_new().
On windows you might not have a theme installed by default which
means that when trying to create the context quark it will fail.
If then we try to replace a NULL key in the hash table it will crash.

Just like GLib, GTK+ would benefit from getting warnings and errors from
the compilers.
We check various, common warnings, especially for a future use of C99;
additionally, we promote some warnings to errors, in order to ensure
that simple mistakes are caught during the development phase, before
they are submitted to the code repository.
Use a static array for the known icon sizes, now that we don't allow
registering custom icon sizes any more. This allows us to cut a one-off
allocation that makes Valgrind sad.
The update tracking code was ugly and using deprecated drawing APIs. It
was also in the wrong place.
So instead of trying to keep it working, I'll remove it. We need to find
a better way to put it and make it work there.
This API was only used in GtkModifierStyle and GtkStyleProperties and
they are both on their way out.
CSS properties must now be set using strings via the regular parser API.
And replaces its usages in GtkTextView/GtkStyleContext with a hard-coded
0.04 which was the default value for cursor-aspect-ratio. Also remove
the public gtk_draw_insertion_cursor which used draw_insertion_cursor
which in turn looked up cursor-aspect-ratio
And with it, gtk_widget_get_visual() and gtk_widget_set_visual() are
gone.
We now always use the RGBA visual (if available) and otherwise fall back
to the system visual.
The cursor was set using gdk_window_set_cursor() even in
gdk_window_new().
So instead of having yet another flag, just make the users of that flag
call gdk_window_set_cursor() directly after the window was created.
X11 was the only backend to support it and people can just override it
using XSetClassHint() directly.
The docs already advertised the function as "Do not use".
Keep the existing call to XSetClassHint() in place, so that we keep
setting the same values as in GTK3.
... and gdk_screen_get_window_stack().
Those functions were originally added in
5afb4f0f11 but do not seem to be used as
they are not implemented anywhere but in X.
As GDK is not meant to fulfill window management functionality I'm going
to remove these functions without replacements.
... and gdk_screen_get_width_mm() and gdk_screen_get_height_mm() and
the shortcut counterparts that call these functions on the default
screen.
Modern display servers don't provide an ability to query the size of a
screen or display so we shouldn't allow that either.
Nobody ever does a NULL check there so all that causes is crashes. So
we better return a non-primary monitor than NULL.
Fixes gdk-wayland always returning NULL.
gtk_widget_destroy() removes widgets from their container. However
_internal_ widgets must be unref'ed using gtk_widget_unparent() instead.
This is symmetric with the fact that these widgets were ref'ed by direct
call to gtk_widget_set_parent(). It's also the method that was used in
gtk_headerbar_destroy().

> Due to Gtk+ keeping a reference to the window internally,
> gtk_window_new() does not return a reference to the caller.

Caller(s) aren't expecting a need to delete help_overlay themselves
once they've installed it. (E.g. see gtk_application_window_added()).
I didn't notice any direct precedents, but there's a parallel in the
current implementation of gtk_container_destroy() which uses
gtk_widget_destroy() on any added widget.
This avoids leaking 100s of kB per window, when I tested nautilus.

This allows the use of a "text-direction" hint set to one of "none", "rtl",
or "ltr" to enforce the text direction of a "horizontal-buttons"
display-hint.
This is useful when a menu has buttons that map to physical space in the
UI and therefore must match the application widgetry.

ClutterEmbed on Wayland uses a subsurface and relocates it on configure
events, but when placed within a scrolled window, no configure event is
emitted and the ClutterEmbed subsurface remains static.
Emit a configure event for native windows in GdkWindow's internal
move_native_children() so that custom widgets relying on configure
events such as ClutterEmbed can relocate their stuff.
Similarly, when switching to/from normal/maximized/fullscreen states
which change the shadows' size and possibly shows/hides a header bar,
we need to emit a configure event even if the abs_x/abs_y haven't
changed to make sure the subsurface is size appropriately.

to hilight drop target there is a wildcard selector which turns
the border and shadow to green, this clearly shouldn't happen when
the whole window is a drop target.
...by putting it in a stack. The busy_spinner and eject_button are
mutually exclusive, but only the latter was coded to ensure that its
visibility did not cause the rest of the row to reflow. By putting both
widgets in a stack and setting child_visible on that, the row allocates
enough space to show one - or none - at once, avoiding any misalignment.

Calling eglGetDisplay forces libEGL to guess what kind of pointer you
passed it. Different EGL libraries will do different things here, and in
particular glvnd will do something different than Mesa. Since we do have
an API that allows us to explicitly type the display, use it.
The explicit call to eglGetProcAddress is working around a bug in
libepoxy 1.3, which does not understand the EGL concept of client
extensions. Since it does not, the normal epoxy resolver for
eglGetPlatformDisplayEXT would not find any provider for that entry
point, and crash when you attempted to call it.

Setting the shadow width earlier as done with commit 4cb1b96 to address

prevents clutter-gtk from relocating its child widget correctly.
To avoid this issue, revert commit 4cb1b96 but make sure the values
passed as min and max size is never negative in Wayland as this is a
protocol error.
With this, the min/max size will be wrong for a short amount of time,
during the state transition, until the shadow width is updated from
gdk_window_set_shadow_width().
This approach is much safer and less intrusive than changing the
size_allocate logic in gtk.
This reverts commit 4cb1b9645e.

After checking for rendered_surface, the call to gtk_css_node_get_style

Endless OS on armv7hl, and this error:

Should avoid randomly colored symbolic icon bits when circles are

Otherwise, with CSD, we could have a discrepancy where gtk uses the
right values for the shadows whereas the gdk backend still uses the old

computed (which, in Wayland, leads a protocol error).

The GLib main loop blocks on MsgWaitForMultipleObjectsEx to
determine if there are any incoming messages while also allowing
for background tasks to run. If all available messages are not
processed after MsgWaitForMultipleObjectsEx has signaled that
there are available, CPU usage will skyrocket.
From my limited understanding (by inspection of profiling
under Visual Studio):
Key is pressed - MsgWaitForMultipleObjectsEx unblocks, and
sends message to GDK's event handler. Some event is now queued.
g_poll unblocks, calls the g_event_dispatch which finally
resolves to gdk_event_dispatch. This then calls
_gdk_win32_display_queue_events, but since a message is already
queued, it fails to call PeekMessage and returns immediately.
At the next iteration, g_poll again calls MsgWaitForMultipleObjectsEx
which queues yet another event and returns almost immediately, since
there are events available which haven't been processed by PeekMessage.
The dispatch function is then called and the process repeats.

The main corpus of the documentation for gtk_window_get_size() is still
full of X11-isms, so we should port it to something that is more
backend-agnostic. Additionally, having some examples would be nice for
application authors looking at a way to appropriately use this function.
If somebody decides to use gtk_widget_set_double_buffered() in the
middle of a draw() then there's the risk of calling end_draw_frame()
with an invalid pointer.
Some overeager compilers may warn about the double_buffered bit field
changing values and leading to a potentially uninitialized variable.
In order to avoid compiler warnings or crashes, we can simply store the
value of the double_buffered bit field at the beginning of the rendering
and use that instead of the actual bit field.

Not all occurrences of this warning can be fixed today, so put it behind

A popup may have moved and resized when configured. Make sure every
layer knows about this and call gdk_window_move_resize() with the

The result of move_to_rect, received from the xdg_popup.configure
event, needs to be translated to the correct coordinate space; that is
from real parent window geometry to coordinates relative to the gdk
window set as transient-for.
https://bugzilla.gnome.org/show_bug.cgi?id=771117
Use a helper to translate a coordinate from non-real GdkWindow parent
to window geometry coordinate space of the real GdkWindow parent,
meaning the coordinate space of the GdkWindow of the parent used as a
xdg_popup parent where (0, 0) is inside of the shadow margin.

Move the code used for calculating the result of move_to_rect

If an application umaps the toplevel from its popup callback, this can

The fix for bug 767468 had some unintended side-effects. This is

Analogous to (un)mount operation, we now keep a reference around
during the ongoing operation and make use of the destroyed flag
to check if we are still alive or if we have been cancelled as
a result of the widget being destroyed.
https://bugzilla.gnome.org/show_bug.cgi?id=764979
Since we hold on to a reference during (un)mount operations, we
don't trigger the cancellation of operations in finalize anymore.
Instead we now override the GtkWidget's destroy() and cancel any
ongoing operations there.
https://bugzilla.gnome.org/show_bug.cgi?id=764979
The current code wrongly assumes that cancellation can only happen
as a result widget finalization, and consequentially does not
properly recover from it. Therefore if the operation is cancelled
as a result of user interaction, the entry is will stay disabled
and the spinner will keep spinning. This is fixed by removal of
the early bail out in case of cancellation.
https://bugzilla.gnome.org/show_bug.cgi?id=764979
During mount and unmount opertions we keep a reference to the

This reverts commit 6af5033386.
Scrolled window behavior of propagating child natural sizes
has now been made optional, so there is no need to work around
this by setting a hard coded maximum content height anymore.
This reverts commit 76af907676.
The behavioral change described in the migration guide
has now been made optional with new scrolled window API,
so no need to mention this in the migration guide.
This reverts commit 37e913d76b.
This is no longer needed since the natural size propagation of
scrolled window children is now an optional behavior. Reverting
this also makes the widget factory scrolled window sizes behave
the same as with the gtk+ 3.20 branch.
In gtkscrolledwindow.c, the return type of _get_propagate_natural_width()
and _get_propagate_natural_height() were accidentally gint instead of
gboolean, fixed to match the type correctly declared in the header file.
The code always assumed that getting a row at a certain 'y' was
possible but if the list box has more empty space than rows then a
valid row may not be retrieved.

When a popup is mapped but will not be the top most popup (for example

Since we're using _get_rect_coords in size-allocate when allocating the
size of the child widget, use the newly introduced _get_rect_for_size to
calculate the difference between the passed size_for and the one we're
supposed to pass on to the child widget.
When calculating the requested size of a popover, we need to do the
exact same same thing _get_rect_coords did, but not for the
current popopver allocation. Add _get_rect_for_size that can be used for
this purpose
Making propagation of child natural sizes mandatory (or default, even) was
evidently a mistake as this causes dynamic content in a scrolled window
to resize it's parent when the scrolled window is competing for space
with an adjacent widget.
This patch instead adds API to control whether natural width and
height of the child should be propagated through the scrolled windows
size requests.
There was a return between a push/pop of an error trap, and
this managed to trigger the 'unpopped trap' warning in the
displayclose test now. Fix this.
Add an API that enables an application to, given an exported window
handle, set its own window as a transient of the window associated with

There is annoying interference between formatting the value
(for which we set the number of digits to show) and the small
frame-to-frame value changes that we do for autoscrolling.
To work around this, turn off the digits-based rounding entirely
and format the value ourselves with ::format-value.
And rename it to "Touch and Drawing Tablets", since it's no longer about
"axes" really.
As for pad support in the demo, just keep it "simple", make the
controller handle all pad devices, and make all the actions have the
same callback.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
The wayland tablet protocol allows notifying the compositor with
descriptions of the actions performed by each tablet element. This
API call allows to hook up in to this wayland-specific feature.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
These devices are kind of an strange case. Their "master" device is
the keyboard, because they share toplevel focus with it, regardless
of stylus focus. Nonetheless, they are only expected to send the
GdkEventPad* set of events.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
This is a subclass of GdkWaylandDevice that implements GdkDevicePad,
all pad features are looked up from the info obtained through the
tablet v2 interface.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
This GdkEventController is a helper object to handle pad events,
it allows setting a mapping to action names, to be triggered in
the given action group.
In order to help on places where advanced mapping/configurability
of pad features is not desirable, this controller also allows
passing a NULL pad device, meaning it will listen on all pads,
and/or passing -1 on mode/index, so an action applies to all
modes/features (eg. strips/rings).
https://bugzilla.gnome.org/show_bug.cgi?id=770026
This is an interface meant to be implemented by the "pad" devices.
This device-specific interface exposes the mapping of all pad features,
it allows retrieving:
- The number of buttons/rings/strips
- The number of groups
- The number of modes a group has
- Whether a given button/ring/strip belongs to a given group
https://bugzilla.gnome.org/show_bug.cgi?id=770026
We want the same treatment for those, the event will be emitted on the
toplevel, which will then decide what to do with the event.
It just doesn't make much sense to propagate those up/down the hierarchy,
when we want specifically one action being triggered from those.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
GDK_PAD_BUTTON*,RING and STRIP will be emitted respectively when
pad buttons, rings or strips are interacted with. Each of those
pad components belong to a group (a pad can contain several of
those), which may be in a given mode. All this information is
contained in the event.
GDK_PAD_GROUP_MODE is emitted when a group in the pad switches
mode, which will generally result in a different set of actions
being triggered from the same buttons/rings/strips in the group.
https://bugzilla.gnome.org/show_bug.cgi?id=770026
An xdg-popup requires a serial that the compositor will compare against
its own serial and will dismiss the popup if it doesn't match.
gtk+ uses either a pointer or touch serial for its helper function
_gdk_wayland_seat_get_last_implicit_grab_serial() but if the menu is
triggered before the user has had any pointer or touch interaction with
the client, using a keyboard shortcut, there is neither pointer nor
touch serial available, and gtk+ will use 0 as the default.
As a result, the compositor will instantly dismiss the xdg-popup. In
this case, gtk+ should use the keyboard serial instead.
Track keyboard serial as well and use the keyboard serial as the value
if there is no newer pointer or touch serial available.

At the time of move_to_rect() is called, not all state may have been set
up on the impl gdk window, causing the position to sometimes be
slightly offset due to drap shadow margins. For now, work around this
by postponing the processing of the move_to_rect() parameters until
showing, when its more likely that all state (such as shadow margin)
has been set correctly.
https://bugzilla.gnome.org/show_bug.cgi?id=769402
The Wayland backend manages a set of fake root coordinate spaces, where
each non-relative positioned toplevel (i.e. not popups, popovers,
tooltips etc) make up the basis of separate fake root coordinate spaces.
This means that the Wayland backend doesn't have the abilitiy get a
proper root coordinate when querying on a non-toplevel GdkWindow. To
avoid this issue, first find the toplevel, while translating the anchor
rect coordinates so that they are in the toplevel window coordinate
space. Then use this toplevel to translate the coordinates to root
window coordinate space.
https://bugzilla.gnome.org/show_bug.cgi?id=769402
The position of each transient-of will be in fake-root coordinate
space; thus we should not accumulate all the positions making it an
offset; each window is already in fake root coordinate space.
https://bugzilla.gnome.org/show_bug.cgi?id=769402
When using the set transient-for as a popup parent, fetch the effective
toplevel instead, otherwise we will position against the wrong
coordinate.

The effect of transitions-enabled=true can now be
achieved using gtk_popover_popup/popdown and the effect
of transitions-enabled=false can be achieved using
gtk_widget_show/hide.
https://bugzilla.gnome.org/show_bug.cgi?id=769706
Since not chaining up in gtk_widget_show/gtk_widget_hide is not allowed,
we can't just implicitly delay the hiding in GtkPopover's hide
implementation. Fix this by introducing gtk_popover_popup() and
gtk_popover_popdown() to show or hide a popover with transition and
revert GtkPopover's show/hide implementation to apply their effect
without the transition.

The order in which tooltips are created, drawn, shown and then positioned,

The GtkHeaderBar gadget implementation was subtly broken: it called
gtk_widget_set_allocation both in gtk_header_bar_size_allocate (with

the content allocation of the main gadget). Dropping the second call
fixes the render node conversion for GtkHeaderBar.

Pick the W32 API for possible deadkey+<something> combinations
and prefer these to other sources of deadkey combos.
Specifically, if W32 API supports at least one combo for a particular
deadkey, only use that data and do not attempt to do other, unsupported
combinations, even if they make sense otherwise.
This is needed to, for example, correctly support US-International
keyboard layout, which produces a combined character for <' + a>
combo, but not for <' + s>, for example.
This is achieved by stashing all the deadkeys that we find in
an array, then doing extra loop through all virtual key codes and
trying to combine them with each of these deadkeys. Any combinations
that produce a single character are cached for later use.
In GTK Simple IM context, call a new GDK W32 function to do a lookup
on that cached combination table early on, among the "special cases"
(which are now partially obsolete).
A limitation of this code is that combinations with more than
one deadkey are not supported, except for combinations that consist
entirely of 2 known deadkeys. The upshot is that lookups should
be relatively fast, as deadkey array stays small and the combination
tree stays shallow.
Note that the use of ToUnicodeEx() seems suboptimal, as it should
be possible to just load a keyboard library (KBD*.DLL) manually
and obtain and use its key table directly. However, that is much more
complicated and would result in a significant rewrite of gdkkeys-win32.
The code from this commit, though hacky, is a direct addition to
existing code and should cover vast majority of the use-cases.
https://bugzilla.gnome.org/show_bug.cgi?id=569581
This changes the group/level semantic.
Previously W32 backend used "group 0/1" to denote "AltGr OFF/ON"
and "level 0/1" to denote "Shift is OFF/ON".
Now "group" means "keyboard layout" and there can be up to 255 groups,
while AltGr and Shift are combined into a single level enum that
takes values between 0 and 4.
Unlike X, W32 doesn't do effective group overriding, meaning that
it will never tell the caller that a different group was actually
used (even for universal keys, such as Enter), because key symbol
table is completely fabricated and there's no point in trying to
save a few of kilobytes of RAM by not duplicating universal key
records for all groups.
Also contains many whitespace changes (tab elimination, fixed
indentation) and cleanup (axed a few global variables, these are
now accessed via the default keymap).

GTK+ has two directories for translations: the default 'po' and the
additional 'po-properties' for the GObject properties translation
domain.
Since the content of the translations directories are filled by
autoreconf and gettext, and are duplicated between the two gettext
domains we use, we should handle this ad hoc inside git.mk, instead of
trying to catch up by adding po-properties files in GITIGNOREFILES.
The contents of the macro directory are too complicated for git.mk to
handle: the contents are filled by autotools and may change between
systems or autotools releases; and we additionally ship our own m4
macros.
To avoid unnecessary noise on the `git status` output we should simply
add an ignore file specifically for the macro directory.
The new positioning-related properties had some quality of
implementation issues, such as incorrect initial values and
excessive change notification. This broke the notify test.
It tried to set the expand state if either xexpand/yexpand where true.
Due to a missing queue_compute_expand when adding a child it actually
only computed the expand state in case a child queued after being added
or in case a child had the expand property set (see optimization in
gtk_widget_set_parent)
In my case this broke layouts as a child of GtkCombBox started setting
an exand flag with 3.20 which queued a compute_expand, which in turn
propagated an expand child props set for a cell in the same table up
and overrode the expand child prop of a parent GtkBox.
This removes the custom compute_expand implementation to match the
behaviour of GtkBox (don't propagate child prop expand flags
but let child expand flags override the child props) and not get random
expand behaviour depending on whether and when child widgets set their
expand state.

GtkShortcutLabel is a widget that displays a single

Scroll history must refer to a timespan for the values to be valid, otherwise
we return FALSE, in this case the stored event(s) should be discarded anyway.
It could be the case that the last scroll event is received long after any
previous scroll event, in this case the last scroll event discards all "old"
scroll events, and scroll_history_finish() returns FALSE because there's no
time/offset deltas in the scroll history.
This is desired so we don't trigger the deceleration effect if there was no
effective velocity, we still must reset the installed scroll cursor, so take
it out of this if() condition.
I thought I needed ot rearrange the ordering of the animation-direction

On X11, device_query_state() uses XIQueryPointer() which will return a
child window only if the pointer is within an actual child of the given
window.
Wayland backend would return the pointer->focus window independently of
the given window, but that breaks the logic in get_device_state() and
later in gdk_window_get_device_position_double() because the window is
searched based on coordinates from another window without sibling
relationship, breaking gtkmenu sub-menus further down the line.
Fix the Wayland backend to mimic X11's XIQueryPointer() to return a
child only if really a child of the given window.
That's the most sensible thing to do to fix the issue, but the API here

Our property parser stops at the first match when looking for
enums, so we need to order our values so that we don't end up
with prefixes of longer names being found first.
I noticed this when the parser tried to interpret
background-blend-mode: color-burn; as "color, with junk at the end".
It also affects animation-direction, which is also fixed here.
After introducing the CSS blend mode enum values and including
the background-blend-mode CSS property, it is very important to
actually provide an example of the new feature.
This patch adds a new demo to gtk3-demo which shows how the
background-blend-mode CSS property works.
https://bugzilla.gnome.org/show_bug.cgi?id=768305
CSS supports blend modes, in which a series of layers are
merged together according to the given operation or set of
operations.
Support for blend modes landed on Cairo, which exposes all
the commons and also the exquisites blend modes available.
Adding support for blend modes, then, is just a matter of
using the available Cairo operations.
This patch adds the background-blend-mode CSS enum property,
and adapts the background rendering code to blend the backgrounds
using the available blend modes when they're set.

I was struggling to understand why calling
gtk_print_unix_dialog_set_manual_capabilities (...,0)
was not having the expected effect of hiding the preview
button. The initial capabilities were not applied at all.
This has most notably impact in selection buffers, because those were
shared across all selection atoms. This turned out wrong on 2 situations:
- Because the selection atom was set at SelectionBuffer creation time, the
GDK_SELECTION_NOTIFY events generated will have unexpected info if the
buffer is attempted to be reused for another selection.
- Anytime different selections imply different stored content for the same
target.
This is better separated into per-selection buffers, so it's not possible
to get collisions if a same target is used across different selections.
https://bugzilla.gnome.org/show_bug.cgi?id=768177
The sanitize_utf8() function has been copied from X11 so both
backends behave the same. This allows interaction with older clients

commit 0015ebc4a8 reworked

This partly reverts 9f5b9c0e07, which

double click -- but those widgets which have it set to FALSE shouldn't
maximize the window.

...or warning style class applied.
This particular style bit wasn't converted to the saner 3.20 way
so `entry:selected` used in place of `entry selection`.

we used to style infobars by using the .info, .question, .warning
and .error selectors directly, which used to be ok when we had just
styleclasses all over the place, now it needs to be more specific
or it interferes with everything with those styleclasses applied
like entries.
The header bar currently ignores the expand property on its
children. This commit changes the code to honor that property.
It divvies up any free space and distributes it equally to packed
children (with any left over space given out a pixel at a time
on a first come, first serve basis).
This commit also adds support for the title widget to be made
expandable.
It accomplishes this by using up the padding the title widget
is centered with.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
In order to support the expand property on children, we're
going to need to look at the size of the packed children
on each side of the title widget, up front, before allocating
them (to compute how much extra allocation each expanded child
gets).
This commit lays the groundwork for that analysis by splitting
the size calculation of each side of the header bar outside
of the loop that allocates each child of the header bar.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
With a headerbar, the widget in the center may be a label, constructed
internally, or a custom widget, constructed externally. The size
allocation code needs to handle either case the same way for the most
part. There's more than one place in the code that checks which of
the two widgets to use and does some operation on the selected one.
This commit simplifies the code by checking up front which one is the
center (title) widget and storing that in a temporary variable,
This allows reducing duplicated logic later on in the function.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
There's some extraneous MIN() calls that have predetermined answers.
This commit drops them and then simplifies a few redudant checks into
one MIN call.
https://bugzilla.gnome.org/show_bug.cgi?id=724332
The size allocation code maintains an array of two elements,
to track the allocation of children packed into the two sides
of a header bar. Sometimes this array is indexed with 0 and 1,
and sometimes its indexed with GTK_PACK_START and GTK_PACK_END.
The latter happen to have the values 0 and 1, respectively, but
that's not really obvious.
For clarity, this commit changes the code to index those arrays
consistently, sticking to 0 and 1 across the board.
It's only possible to have a label or a custom title, not both.
The size allocate code confusingly treats them as independent.
That is confusing, because, as the code is written, it makes it
look like the space for the custom title isn't getting accounted
for.
This commit else-ifies some parts of the size allocate code for
clarity.
Firefox does a bunch of interesting things with GTK.
If the top-level GtkWindow does not have a "csd" style class associated,
Firefox will happily draw the contents of the container used to render
HTML and XUL directly on the top level's GdkWindow; on the other hand,
if a "csd" style class is found, the MozContainer will create a new
child window, and draw on it.
Then, Firefox will proceed to disable double buffering on both the
top-level window and the MozContainer (unless they are backed by the
same GdkWindow, in which case only the top-level will be
single-buffered) *and* it will add a GDK_EXPOSURE_MASK flag to the
MozContainer events for good measure (even if this is only needed for
GTK+ 2.x).
After landing the GdkDrawingContext API in GdkWindow, GTK enabled
automatic double buffering on all top-level windows backed by a native
surface, ad most users of single buffering rely on child widgets instead
of top-levels, and we'd still like to have the same double buffering
behaviour for all top-levels on all backends. Obviously, with Firefox
disabling double buffering on the top-level window, the change broke
their drawing mechanism.
Ideally, Firefox could be fixed to not disable double buffering on the
top-level window when MozContainer has a separate GdkWindow — i.e. the
CSD case — but since we did introduce a slight change of behaviour in
fringe users of the GTK+ API, let's keep backwards compatibility with
the old code for a little while longer, and create an intermediate Cairo
context unbound from the GdkDrawingContext, like we used to do until
GTK+ 3.20.
And ensure it's still visible before returning the keyboard focus to it.
Because of the extra ref, add a dispose handler that will ensure the
ref is lost (by popping down), although this should be already ensured
through other paths (eg. when the popup widget loses visibility).
This fixes a possible crash in dispose paths, where we might be restoring
focus on an already destroyed widget, and at a time where, if the toplevel
is being itself disposed, no new focus should be set.
https://bugzilla.gnome.org/show_bug.cgi?id=767849
If there are widget margins set, the whole popover will be displaced.
However the calculation of the tail position doesn't have this into
account, ending up with the tail being detached from the popover if
the margin grew too big.
We should not render the arrows invariably next to the GdkWindow edge,
but optionally displaced inside it depending on the widget margins.
Fixes the gtk3-demo "Popovers" demo case, whose GtkEntry popovers set
widget margins for some reason.
https://bugzilla.gnome.org/show_bug.cgi?id=767851
do_sort will crash if sort_func is not defined. Instead of adding a check
there in the hot path, just check for sort_func before invalidating the
sort of the underlying GSequence.
I noticed that some of the gestures did not show up in the
search results in the builder example in gtk3-demo, because
they share the same title and don't have an accelerator to
disambiguate. Include the shortcut type to handle this case.
Set a max-content-width on some of the scrolled windows to
keep things looking mostly the same, now that GtkScrolledWindow
passes along the natural size of its child.
The cellrenderer signals might be taking the grab somewhere else, at which
point it's dubious we should attempt to take the keyboard focus into the
treeview.
This concretely breaks popovers triggered from cellrenderer signals on
button press, because the treeview will attempt to grab focus
inconditionally then.

Previously a style cascade's parent could not have a parent itself. That
represented the two levels at which you could add a style provider: at
the screen level, with gtk_style_context_add_provider_for_screen(), and
at the style context level, with gtk_style_context_add_provider().
This commit changes no functionality, but this change will be necessary
for adding style providers in the future that apply to a subtree of the
widget tree. It relaxes the requirement that a style cascade's parent
must not have a parent, since in the future a style context may be
affected by any number of parent widgets' style contexts.

Debian stable currently ships with a 3.16 kernel, so
it doesn't have memfd available.
This commit adds shm_open fall back code for that case
(for now).
https://bugzilla.gnome.org/show_bug.cgi?id=766341
We currently use syscall() directly to invoke memfd_create,
since the function isn't available in libc headers yet.
The code, though, mishandles how errors are passed from syscall().
It assumes syscall returns the error code directly (but negative),
when in fact, syscall() uses errno.
Also, the code fails to retry on EINTR.
This commit moves the handling of memfd create to a helper function,
and changes the code to use errno and handle EINTR.
https://bugzilla.gnome.org/show_bug.cgi?id=766341
When disposing a GdkDrawingContext we should unset the association
between the instance and the Cairo context; this avoids stale pointers
in case a reference that has acquired on the Cairo context survives the
lifetime of the GdkDrawingContext.
This is a bit of fallout from 34feba1, now that we resolve
the has_indicators value earlier than realize, it becomes
possible to call gdk_window_move_resize() before realization.
Just added the appropriate checks.
Instead of associating the GdkWindow that created the GdkDrawingContext
we can directly bind the Cairo context to the GDK drawing context.
Cairo contexts created via gdk_cairo_create() go back to not having a
GdkWindow associated to them, like they did before we introduced the
gdk_window_begin_draw_frame() API.
https://bugzilla.gnome.org/show_bug.cgi?id=766675
Instead of giving out Cairo contexts, GdkWindow should provide a
"drawing context", which can then create Cairo contexts on demand; this
allows us to future proof the API for when we're going to use a
different rendering pipeline, like OpenGL.
https://bugzilla.gnome.org/show_bug.cgi?id=766675
Existing code drawing on a GDK window has to handle the direct drawing
and the buffered drawing by itself, by checking the window type and
whether or not the window is backed by a native windowing surface. After
that, the calling code has to create a Cairo context from the window and
keep an association between the context and the window itself.
This is completely unnecessary: GDK can determine whether or not it
should use a backing store to draw on a GdkWindow as well as create a
Cairo context, and keep track of it.
This allows to simplify the calling code, and enforce some of the
drawing behavior we want to guarantee to users.
https://bugzilla.gnome.org/show_bug.cgi?id=766675
The maximum content size does not increase the minimum request
but only ensures that both minimum and natural requests do not
exceed the maximum setting.
Widgets should support size requests before being realized in general,
otherwise this can cause flicker/resize at initial display time as
the toplevel window can make a request before realize/allocate.
This also makes the added testsuite/gtk/scrolledwindow.c test work again,
this was broken because we only ever calculate whether we are going
to use overlay scrollbars once the scrolled window is realized (and
the test case does not realize any window).
This patch does a couple of things:
o Removes the obscure 'extra_width' and 'extra_height' variables
making the request code exceedingly difficult to read
o Fixes the max-content-size properties introduced in bug 742281
so that they do not grow the minimum request.
o Cleanup of request code in general:
- min/max content sizes are clamped around the child request as needed
- scrollbar requests are only added in one place, after child request
sizes are calculated and without the extra_width/height thing.

With the FTS5 query syntax, when using quotes to delimit the search phrase
the '*' token must happen after the quote, or will otherwise be considered
a character to match, go through the tokenizer, and end up ignored in
result.
This reverts commit 0943c9f6b2.
The commit caused unexpected breakage in gtk3-widget-factory,
and also broke the just-added max-content-size properties.
Needed to adjust this again after applying commit 4e5ecb7
for bug 742281. Now that we also have max content size properties,
pushed the addition of possible scrollbar sizes to after the
clause which clamps the child request size into min/max content
sizes.
Commit a01fe14 changed the behaviour of popovers when the focus leaves
them to stop child popovers being hidden when the focus leaves their
parent. However they are now a bit too reluctant to hide - if the
focus passes to an unrelated popover the first popover is not
hidden. Also if the focus passes to another widget that does not
perform a gtk grab then the popover isn't hidden until the user
presses a non-movement key or clicks outside the popover.
The solution is to go back to checking if the focused widget is a
descendant of the popover, but to include popovers and their related
widgets in the ancestry chain.

This patch causes the scrolled window default behavior to change in
such a way that the natural size request of the child is unconditionally
reported, which probably should have been the case since day 1.
This should not cause significant fallout since a scrolled window is
normally used to expand/fill, eating up remaining space for scrollable
content - it will however cause the scrolled window to compete for
additional space with siblings, proportionally to the size of the
scrolled window's content.
gtk_tree_view_get_path_at_pos() mistakenly identifies the first
pixel of all but the first column in a tree view as belonging to
the previous column.

The GtkScrolledWindow has support to set the minimum content size (both
width and height) which controls the minimum space allocated, but does
not exposes any way to control the maximum size the content can grow.
After the introduction of GtkPopover, which always uses the minimum
size of it's children widgets, the lack of max-content-width and -height
properties became a concrete use case.
This patch introduces the GtkScrolledWindow::max-content-width and
-height properties. The properties will alter the minimum size of
the scrolled window, making it grow up to the set value. They also
respect the previously set ::min-content-width and -height.

GtkHeadeBar checks the window type hint to determine if the regular
buttons such as menu, maximize or iconify should be visible in the
header bar.
However, an application may very well use a "normal" toplevel window and
set it transient and modal afterwards. In such a case, the iconify
button would remain visible, and the user can hide the window, but being
a modal, the parent window would remain insensitive.

whether or not the regular toplevel buttons should be visible in the

Calling gdk_gl_context_realize() should always result in a valid result,

If the popover's relative-to widget is unparented/reparented, we end
up unparenting/reparenting the popover as well. In that case, at the
moment of reparenting, the widget might have been visible (and is

gtk_widget_set_parent() will map the widget if the parent is mapped
and the widget is both visible and child-visible. As we currently

map all children that are added to a mapped stack, even when they
are not actually shown. Avoid this by setting the child visibility
before adding the child, so widgets are only mapped when shown.

GtkScrolledWindow leans towards using the minimum size of its child
widget, unless the scrollbar policy is GTK_POLICY_NEVER. This is
probably fine for most GtkScrollable implementations out there.
Especially when using GTK_SCROLL_MINIMUM, which is the default for all
implementations inside gtk+.
However, this is not good for GTK_SCROLL_NATURAL children. eg.,
VteTerminal's minimum size is 1x1 and natural size is the number of
visible rows and columns requested by the user. We really want to use
the natural size unless the user has resized the window to change that.

there is more to it when there actually isn't.

When we are beginning to calculate the height, if the vscrollbar_policy

Simply put, this should be the mirror image of the corresponding width
calculation code.

GTK used to not emit GtkWidget::style-updated on widgets that weren't
realized. This sped up construction of complex widgetry in the early
days of GTK3 where we instantly invalidated on every change.
We don't do that anymore, so in theory (and in my limited testing with
widget-factory) this shouldn't be a prolem anymore.
What is a problem though is that postponing style-updated leads to 2
problems:
(1) Unrealized widgets will not emit style-updated which may cause them
to not properly update their state and return wrong values from
get_preferred_width/height() etc
(2) Emitting style-updated during realize can happen too late.
When a widget is not made child-visible by its parent (common
examples: notebook, paned) it will also not be realized when the
parent is initially shown. However, when they get realized later
(after a resize of the parent), they will emit style-updated (and
potentially queue a resize) during size-allocate.

We're measuring both the width of the minimal and the maximal value for
the value gadget, but only give the value the minimal width for its

Fix this by assigning the width of the value gadget to the value layout
and letting pango align the text inside the layout.

Menus are placed vertically by definition, it does not make much sense
to support horizontal axis for scrolling.

On X11, we get both smooth and emulated scroll events, whereas other
backends such as wayland will give smooth events only with touchpad
scrolling.
Discard emulated scroll events so that we get consistent behaviours
between backends.
Allow for both horizontal and vertical smooth events for scrolling so
that horizontal scrolling still works without emulated scroll events as
well, again for consistency between gdk backends.

Some compilers we support, such as pre-2013 Visual Studio, does not support

Split out the part where we generate/update the caches for the GSchemas

Children tend to call back into the scrolled window while being removed
and that doesn't work too well if the scrolled window is destroyed
already as Christian Hergert found out.
Consolidate the .lib's that we need to link to for GDK and GTK+ into the
property sheets, and also link to setupapi.lib as that is needed by
the port to the new GdkMonitor API.
WINBOOL is MinGW-specific, so change it to BOOL, which is universally
available.
Also, Visua Studio is more picky on where __stdcall (WINAPI) is placed, so
fix that to be in-sync with what is done in the other sources.
This only used by luck before. We are changing a property from the
::notify handler for that property. Now that GtkRevealer is notifying
the property when it stops animations on unmap, we end up in a life
lock situation where we never make it out of the notify queue.
Fix this by not restarting the animation if the widget is unmapped.
Depending of float rounding during target calculation, the size of the
GtkRevealer can be set to zero will the animation is not finished.
If the GtkRevealer is in a GtkPaned, it will be hidden and so the animation
will be stopped before it is finished.
In this case, force the emission of the child-revealed signal to let
client code know the animation is finished.

This was another very frequent use of qdata. Since we typically
have only one or two display objects, storing the display-settings
association in a simple array is faster than using object data
or a hash table.
Use of g_signal_handlers_disconnect_by_func() needs to do more work than
necessary to find all the matching handlers. Instead, just hold on to the
signal identifier and remove it directly so we hit the fast path.
Not terribly ground breaking in terms of performance gains, but its done
enough to be worthwhile.

Christian Hergert reported seeing webkit crashes with recent
GTK+. The stacktrace points at the CSS machinery calling into
GtkSettings to get the font name, and then getting surprised
by a property notification that triggers style validation.
To avoid this, query the font name xsetting right away when
we get set a screen.
The active keyboard grab can be spared then. This way the passive
key grabs allow other key combinations (eg. alt-tab) that are not
mandatory to grab here.
This will almost certainly overwritten before the widget gets
to the screen, but while we are doing this, we might as well
use the same state that we initialize the widgets state to.
Instead of creating 2 pango layouts in every draw() and on in
_get_content_size (and calling into gettext twice in both cases), just
keep the layouts around and create them in only one place.
I was somehow under the misconception that we'd get GdkEventSettings
events for all the xsettings at startup. That is not in general true,
so we need to make sure that we check for the xsettings value before
we use them, or derived fields. Update all the private getters to
do so; and fix settings_update_font_values() to cope with font
descriptions that might miss the family or size.
I mistakenly assumed that gtk_settings_init was already doing
something to trigger a notify for all properties. It doesn't,
so we have to ensure that settings_update_font_values() is
called at least once.

The wayland specification for discrete step information for scroll and
other axes reads:
| The discrete value carries the directional information. e.g. a
| value of -2 is two steps towards the negative direction of this axis.
mutter sets a value of 1 for SCROLL_DOWN events and -1 for SCROLL_UP
events.
gdkdevice Wayland backend does the opposite, it translates a positive
discrete value as SCROLL_UP and a negative value as SCROLL_DOWN, which
ends up inverting the scrolling direction.
Fix the logic in gdkdevice Wayland to use a positive value as
SCROLL_DOWN and a negative value as SCROLL_UP so that it matches mutter
and weston logic.

The fallback code for rendering builtin checks, radios
and expanders was using border parameters. With the generic
gadget borders using the same parameters, this was giving
double borders.
Before commit 6c1bee2377 we were setting an attribute of GtkNotebook
to track the pressed button if the pressed button happened on the
tab itself.
Later in the motion handling code we were checking whether the private
pressed button attribute was set or not in order to handle a tab dnd
or not.
In commit 6c1bee2377 the code changed and set the pressed button
variable unconditionally, which means, a motion event from within the
tab content triggered a tab reordering.
This happened only if the children hierarchy have a widget that bubbles
up both button press event, which sets the private pressed button
attribute; and motion events, which started the tab dnd checking the
private pressed button attribute.
A widget that experienced the regression was GtkListBox.
In order to fix it, set the button pressed variable only when it press
the tab itself, not the content.

We only keep one align flag per child, so it seems odd to
keep separate h/v expand flags. Just keep one expand flag
and interpret it according to orientation. Allow setting
the expand flag for child widgets too, though, so we can
make widget expand without interfering with the recursive
widget expand flag.
Update all callers.
Use the new possibility of expanding child widgets to make
the label of check and radio buttons expand. This fixes
unexpected behavior of these widgets in RTL in some places.

In RTL, we want to interpret GTK_ALIGN_START and _END

If the monitor vfuncs are not implemented in a display class,
fall back to providing a single monitor object representing
the entire screen. This is not meant to be 'good enough', it
is just to provide some implementation until all backends
implement the monitor vfuncs. When that is the case, the
fallback should be removed.
If there was a piece of text in the cell, then when the edit
entry is shown for that cell, it should have a piece of text
in it roughly at the same location.
Therefore, when child widget is enlarged (child preferred
size exceeds cell size), extra width should be added by
extending either left or right edge depending on text direction.
If after that the child sticks outside of the treeivew visible region,
try to push it back inside (breaking its alignment with the
cell), again, giving preference (i.e. adjusting it last)
to either left or right edge depending on text direction.

NoSymbol is not a valid GDK symbol (it only has the concept of
VoidSymbol, for some reason, which is neither the same thing nor

apps is unlikely to produce anything useful.
In particular, this meant VTE would scroll to the end of the buffer when
pressing Fn (required for Page Up/Down on Macs), as it was receiving a

Instead, we reuse our previous source and update the ready time to our

The documentation clearly says that the widget is not destroyed,
but we were in fact failing to keep it alive, since it was still
a child or the icon_window when we destroy that. Fix this by
reparenting the icon_widget out before. Also, deal with the
possibility that the application might destroy the widget
halfway through, for whatever reason.
I added a new test function, but didn't actually use it.
No wonder I couldn't reproduce the lifecycle issues with

This patch renames all occurrences of "wayland_display" to

We perform lots of gadget allocations that require allocating a
GtkBuiltinIcon. One notable example is the scrollbar for a scrolled
window.
In the process of doing this, we often calculate baseline information that
isn't necessary. With how much this code path gets exercised, its worth
catching the result for the common case, which is that the font-description
has not changed and we are using the default language the application
was started with.
This simply caches the previous result and verifies that we can reuse it
with pango_font_description_hash() and a simple language check.

This allows us to decide when the R and B color channels should be
flipped with a much better granularity.
For instance, when using GLX_EXT_texture_from_pixmap to create a GL
texture from a surface we don't need to swap the R and B channels, as
the internal representation of the texture data will already have the
appropriate colors.
We also don't need to flip color channels when blitting from a texture.
Cairo surfaces are in BGRA format, but we upload them as RGBA buffers on
GLES; this means that the R and B channels are flipped in the texture
data.
Instead of doing a costly channel flip before putting them on the GPU,
we can flip the values inside the GLSL shader we use specifically for
GLES.
We cannot use GL_BGRA and GL_UNSIGNED_INT_8_8_8_8_REV when reading back
from the frame buffer in the software fallback path, as they do not
exist on OpenGL ES.
This will make the slow path a bit slower, because of the implicit
format conversion.
When uploading a Cairo image surface to a GL texture we cannot use
GL_BGRA and GL_UNSIGNED_INT_8_8_8_8_REV on OpenGL ES, as they do not
exist in the core spec.
On some platforms we can ask the GL context machinery to create a GLES
context, instead of a GL one.
In order to ask for a GLES context at GdkGLContext realization time, we
use a bit field like we do for forward compatible, or debug contexts.
The 'use-es' bit also changes the way we select a default version,
because OpenGL and OpenGLES versions differ.

When decelerating the kinetic scroll, we can get into a position where it
looks like we are stuttering. This happens because the amount we move is
so little that it takes multiple frames to make forward progress by one
pixel.
This prevents that by detecting when we have reached the slow stutter of
the deceleration and simply stops the deceleration phase immediately.

This has several benefits:
- Less code in GtkApplication. The accels handling is something
self-contained, and GtkApplication now delegates the work.
- For the accels functions, there is now a distinction between static
functions and functions in the gtkapplicationaccelsprivate.h header,
which makes the code easier to understand, because we have a good
overview just by reading the header.
- The struct _GtkApplicationPrivate is now easier to find instead of
being in the middle of the file.

These will become the functions present in the

If we get gdk_wayland_seat_flush_frame_event() with no previous event to be
flushed, we fallback into the scroll event checks. However, there's no check
performed there as to whether it really scrolled, so it'd always send a smooth
scroll event with 0/0 deltas in this case.
This should be mostly harmless, but still, we should only end up emitting scroll
events if those really happened.
The frame event is also meant to compress wl_pointer.leave events, at this

Worth noting that gtk css font-size will still behave differently than the

Because of our port of css animation and css transition to
progress tracker, we should not think of animated styles as
immutable objects that can map any timestamp to css values.
Rather, timestamps can correspond to different values depending
on the value of GTK_SLOWDOWN over the course of the animation.
To keep animated styles and style animations totally immutable,
we will not share styleanimations between animatedstyles, and
make a new copy of a styleanimation for each timestamp.
Not the ideal solution for this problem, but in practice leads to
much better performance on lower end hardware.
Stack does a double draw on the first frame of its animation, of
both the old contents (into a cairo surface) and the new contents.
Homogeneous stacks only need to reallocate contents on the first
frame.
On lower powered hardware where our frames will be a good deal
slower than the refresh rate anyway, we can assure a smother
experience by waiting a frame to start tweening where frame duration
will be more consistent.

On wayland, such axes are per-tool, we must update device capabilities
on the fly as new tools enter proximity, first the slave device so
it matches the current tool, and then the master device so it looks
the same than the current slave device.
Only the management of tablets and tools is added so far. No tablet events
are yet interpreted.
As it's been the tradition in GTK+, erasers are split into their own device,
whereas the rest of the tools are meant to be routed through the
GDK_SOURCE_PEN device. Both pen/eraser devices are slaves to a master
pointer device, separate to wl_pointer's. This is so each tablet can
maintain its own cursor/positioning accounting.

This will enable multiple "pointers" to have separate data here.
Will come out useful when adding support for tablets, as they
will have a separate cursor for all purposes.
On wayland we get separate master/slaves for each tablet, we will
need to receive crossing events for each master pointer if there's
more than one around.
Axis labels are very X specific, and are not really possible to port to other
backends such as Wayland. As such, it makes more sense to use GdkAxisUse and
GdkAxisUseFlag in order to determine the axis capabilities of a device and draw
their axes.

Because there are multiple different types of styluses that can be used with

on slave/floating devices whenever the tool they are interacting with
changes. These notifications may also work as a sort of proximity events,
as the tool will be unset when the pen moves too far.
For backends, gdk_device_update_tool() has been included, all that should
be done on their side is just calling this whenever any tool might have
changed.
GdkDeviceTool is an opaque object that can be used to identify a given
tool (eg. pens on tablets) during the app/device lifetime. Tools are only
set on non-master devices, and are owned by these.
The accounting functions are made private, the only public call on
GdkDeviceTool so far is gdk_device_tool_get_serial(), useful to identify
the tool across runs.
This fixes a bug that was introduced by db1b24233e.
The reason why 0:0 coordinates were passed was that SWP_NOREPOSITION was
misinterpreted as SWP_NOMOVE. That is not the case - SWP_NOREPOSITION
prevents owner Z-order change, not the window position change.
gnome-control-center is calling gtk_window_resize() on configure-event
signals which leads to a busy loop.
Avoids such a busy loop by not re-configuring a window with the same
size, unless this is coming from and xdg-shell configure.

A naive way to perform an action on all parent nodes of a given node
could be to do:
while(gtk_tree_model_iter_parent(model, &iter, &iter)) {
/* perform some action on iter here */
}
However, since gtk_tree_model_iter_parent() will initialize the iterator
pointed to by the second parameter before performing the lookup, this
will not work.
Explicitly document this behaviour.

We use a label_sizing_box to make sure the headerbar can always contain
both a title and a subtitle without resizing when showing/hiding either
of them, but we should only do that for the height; the min width of the
label_box can be larger than that of the label_sizing_box.
Commit cdc580463e made it so that
unresizable windows can't be smaller than a set default size but it
lost the logic to ensure these windows remain at least big enough to
comply with their requisition.

When we invalidate a window we need to also invalidate all child windows
that are native (non-native are automatically invalidated as we track
invalidation once per native window only). This was done in a pretty
inefficient way, recursing over the entire tree.
This makes the invalidation much faster by only looking at the native
children of the native window we're in, filtering out those that
are not a descendant of the client side window we're interested in.
Given that there are very few native subwindows this is much faster.
We were missing all of the status directories, and a few sizes.
This was causing us to not find image-missing on systems without
hicolor icon theme (this basically only happens on Windows).

e8aa9b0440 introduced a new debug mode
that highlights resizes. Unfortunately it has the side effect of
always queueing redraws even when the debug mode is not enabled.
Make the redraw conditional.
Currently only one kind of decorative window is in use - the shape
indicator that is shown when snapping windows to the edge of the screen.
When normal toplevel class is used, its window procedure expects certain
motions from GDK (passing user data to CreateWindowEx(), registering
handle in a hash map etc), and might crash if that is not done.
Dumb window doesn't require anything, it can just be.
https://bugzilla.gnome.org/show_bug.cgi?id=763013
Now halfleft/halfright/fullup snaps do hug screen edges as intended.
Documents AeroSnap behaviour when snapped windows are drag-resized
(currently this implementation handles this in a very simplistic way).
Don't believe GTK when it tells us that window shadow is 0, preserve
previous values (but do remember that GTK wants no shadow, in case
we need that).
Fixes a couple of bugs in unsnapping (check offset against the half
of the window; don't put pointer in the middle of the window vertically
if it still fits in the top half).
https://bugzilla.gnome.org/show_bug.cgi?id=763013
Implements gdk_win32_window_set_shadow_width().
Uses shadow width/height to adjust max tracking size, allowing
windows to be drag-resized to cover the whole desktop.
Also uses SM_C*VIRTUALSCREEN instead of SM_C*MAXTRACK.
https://bugzilla.gnome.org/show_bug.cgi?id=763013
Indicator is a bare layered click-through native window,
painted completely by GDK, including animation.
This commit also isolates some of the more spam-ish debug logging
under ifdef.
This commit also changes the system metric used for maximal window
height for the snapping purposes. Turns out, SM_CYMAXTRACK is way
too large, use SM_CYVIRTUALSCREEN instead.
https://bugzilla.gnome.org/show_bug.cgi?id=763013
This implements the part of AeroSnap that snaps windows when you
drag them (while moving or resizing) to the edge of the screen.
It also fixes drag behaviour for snapped and maximized windows
(if such windows are dragged, first they must be unmaximized/unsnapped).
Note that this code does not take into account the shadow width, and
because of that the under-pointer-position-preserving window moves
might not look as such for maximized windows, which lack the shadow
when maximized, but do have the shadow when unmaximized.
This commit also doesn't cover some corner-cases the same way AeroSnap does.
Also, the snapping indicator (which is supposed to be a window shape that
shows where the window will be if the drag op is stopped at its current
point) is not being drawn, all routines responsible for its creation,
moving and drawing are stubs.
https://bugzilla.gnome.org/show_bug.cgi?id=763013
This is what AeroSnap does. If a window is being unsnapped on
a new monitor, check if the work area is large enough for the
window to fit in its normal size. If the window fits, just
reposition it so that the ratio of
left-window-edge-to-screen-edge / right-window-edge-to-screen-edge
remains the same, without scaling the window.
https://bugzilla.gnome.org/show_bug.cgi?id=763013
It works exactly like AeroSnap.
Except for shift+win+left/right, which is left for AeroSnap
to handle (AeroSnap takes action before we get the message,
so there's no way for us to override it).
The only thing that doesn't work is shift+win+left/right on
a maximized window, for reasons unknown at the moment.
This only implements winkey+stuff behaviour of AeroSnap,
not the drag-to-the-edge-and-something-funny-happens one.
https://bugzilla.gnome.org/show_bug.cgi?id=763013
If a layered window was hidden and is made visible, erase its
contents before showing it. GDK will schedule a redraw, but until
then we generally don't want to show old contents.
https://bugzilla.gnome.org/show_bug.cgi?id=763783
This is achieved by sending undocumented message WM_SYSMENU
to the window.
Before doing that, the window is given WS_SYSMENU style
(to enable window menu) and some combination of
WS_MAXIMIZEBOX (for "Mazimize" item)
WS_MINIMIZEBOX (for "Minimize" item)
WS_SIZEBOX (for "Size" item)
depending on which operations are currently permissible.
WM_SYSMENU is processed by DefWindowProc(), which results
in showing the window menu. We remove extra styles
at the first opportunity (WM_INITMENU message), as they
alter the way our window is rendered.

While this commit was found to make emacs windows shrink (and it was
reverted in the gtk-3-20 branch for that reason), that was the only
observed breakage, while the reversal broke several of our unit tests.
Closer study of the emacs sources revealed that it does some really
unsupportable things like doing its own X event handling behind GTK+'s
back and freely mixing sizes of GtkWindows and GdkWindows obtained in
various ways. I've filed a bug against emacs with suggestions for how
to avoid the shrinking window, regardless of this commit.
Original commit message:
It seems this branch is not needed anymore. It was originally added in
1999 to support gtk_widget_realize(), but all those reasons seem
obsolete today.
Instead just call gtk_widget_realize().
If you end up at this commit when bisecting:
There is no bug that made me remove this code, it was purely meant to be
cleanup / dead code removal. I seem to have introduced a new bug or
bisecting wouldn't have let you here. So it seems we should just revert
this commit.
Since we are really only interested in the center point of the
slider allocation, the pre-computed slider geometry is perfectly
fine, just use it always. This avoids the complication with
gadget visibility.
The slider gadget may be turned invisible as side-effect of
gtk_range_calc_slider(). If that happens,
gtk_css_gadget_get_content_allocation() returns { 0, 0, 0, 0},
which leads us to calculate a negative allocation for the highlight
node. Avoid this, by just reusing our already calculated slider
allocation in this case (it is not technically the same as the
content, allocation, but the difference hardly matter here.

These functions are supposed to return the numbers of consecutive
1 bits in each components mask as precision. However, due to a
copy-paste mistake when this code was moved around in
commit 70d689cddd, the precision
was always reported as zero. This affects only a few applications
that directly set window background on X11 windows, such as emacs.

Error codes can be easily looked up in an error code list

The trash is monitored for state changes - going from empty to non-empty and the
other way round. Monitoring is done by handling change signals from a regular
file monitor. On each signal, an enumeration of the trash contents is started in
order to see if it is empty or not. This causes issues when many files are
trashed, because the gvfs trash backend is flooded with enumeration requests,
resulting in CPU usage spikes. In order to fix this, the "item-count" attribute
of the trash should be queried instead.
Replace asynchronous enumeration with asynchronous information query and update
the trash state based on the "item-count" attribute. Emit state change signal
only when the state actually changes.

gtk+ currently depends on the scaling factor and the cairo device scale
of both the backend surfaces and image surfaces to be equal.
Until now we didn't apply a cairo device scale at all and depended on the
automatic scaling of CGContexts. This works when drawing with cairo but
fails in case of image surfaces, which get requested at a too small size.
To make the quartz backend behave more like the X11 one, set the cairo device
scale on the surface in gdk_quartz_ref_cairo_surface(). As this conflicts
with the default scaling done by CGContext (we would get double scaling)
undo the CGContext scaling using CGContextScaleCTM().
This patch is based on the following patches by Brion Vibber:

When loading a per-theme settings.ini file, look for it in
the same directory where we found the gtk.css file for the

$prefix/share/themes/THEME/gtk-3.0/, even if the css was
loaded from somewhere else.
https://bugzilla.gnome.org/show_bug.cgi?id=641354
With this change, we now look in

Now that GdkWaylandDeviceData is gone, the functions prefixed
"gdk_wayland_device_" and taking a GdkWaylandSeat as first

It's the same than gdk_device_get_seat() nowadays. Also, rename the
usages of GdkWaylandDeviceData to GdkWaylandSeat in the functions
affected by the removal.

When animating, we might be changing the size allocation of the previous
stack child. However, we were not querying the size in the process
meaning you would often see warnings about allocating the size without
knowing what it should be.
This simply adds an innocuous size request, since responding to last_child
sizing requests is not all that critical in the transition.

backdrop wasn't in the mix, added and adjusted other widgets
styling not to be overridden by it when not needed.
Spotted a typo making the backdrop base color white in the process.
Using UpdateLayeredWindow() on iconic windows brings them *back* from
their iconic (minimized) state. That is bad.
As a precaution, also don't use SetWindowPos() on iconic windows.
This means that iconic windows can't be moved. That is fixable
by using SetWindowPlacement(), but there is no pressing need to do so,
as there are very few cases when windows need to be moved while minimized.
https://bugzilla.gnome.org/show_bug.cgi?id=763835
Some applications set both a default size on their gtk window and a size
request on the corresponding gtk widget.
Until now, the default size was ignored for fixed size windows, so this
had no effect and remained unnoticed, but with the recent change for
client-side decorations, the default size is now used even for fixed size
windows, which can cause the resulting fixed size window to be much
smaller than expected with the size request.
For fixed size windows, if we have both a size request and a default
size set, prefer the size request as before.

if (orientation) doesn't make a lot of sense but C doesn't complain and
instead evaluates orientation to TRUE for GTK_ORIENTATION_VERTICAL
(since that's 1), thus inverting the value sizes.
commit c3dc0d80f1 fixed the behavior of
GtkContainer widgets requesting an IMMEDIATE resize-mode.
However, GtkWindow has been stomping on resize-mode during realize()
since commit addcc64b9c. The combination
of factors that led to this not being a visible problem during all this
while is uncertain, but this now causes the Shell to continuously try to
relayout its ShellEmbeddedWindow (a GtkWindow subclass).
This commit separates the resize-mode as set internally by GtkWindow
from the one set with the external API, so that GtkWindow only changes
it when it had not been set before by the subclass.

The implicit grab may be finished so the pointer lies on top of the other

The way gdk_drag_status() may be called multiple times during the
processing of drag and drop events throughout the widget hierarchy
brings some superfluous messaging going in, esp. when it's the last
request the one we want to honor, yet we emit messaging requests on
all.
This is barely appreciable in the X11 backend, but due to the design
of the wayland protocol, quick series of changes like this it have
some self-amplificating consequences which may end up flooding the
connection.
We can delegate this to a late "commit" call, performed within GDK
event management. This way gdk_drag_status() calls may be cached
and only result in windowing messaging once per ::drag-motion or
::drag-data-received event. Emitting the final status will also
avoid spurious action changes on the compositor and the other peer.
https://bugzilla.gnome.org/show_bug.cgi?id=763298
Besides the ::drag-failed handling in order to trigger the window creation
hook, add some handling of the application/x-rootwindow-drop mimetype, so
the same effect is achieved if the tab could be dropped in a destination
accepting this mimetype.
https://bugzilla.gnome.org/show_bug.cgi?id=763387
This makes toplevels pseudo-transparent wrt this mimetype, so if
the drag source offers this mimetype and not another that was
managed by the destination-side widget hierarchy, the window will
be an acceptable target for this mimetype, allowing it to trigger
whatever is meant to in the source side.
https://bugzilla.gnome.org/show_bug.cgi?id=763387
This code:
> gdk_window_get_root_origin (window, &x, &y);
> x -= root_x;
> y -= root_y;
> pointer_window = gdk_device_get_window_at_position (device, &x, &y);
was meant to find the child gdk window at coordinates root_x and root_y.
These 4 lines had 2 bugs:
1) x = x - root_x (same for y) is wrong, it should be x = root_x - x
2) gdk_device_get_window_at_position() does not give you the window
at position x and y. It gives you the window under the device
(mouse pointer) and the returns the device coordinates in x and y.

Don't make the popup follow the slider while it is open; that

We were not taking the scrollable borders into account when
requesting size for the scrolled window, which could lead
to underallocating the scrollbars at size allocation time
when we *did* take the borders into account.
This is most notable with treeviews, where we have the
headers as borders, and was causing the treeview-crash-too-wide
reftest to fail.
This test has a word that wouldn't fit in the room we have with
a window width of 100, and then we get clipped in the one case
but not the other. Make the window a little wider, so it fits.
The tree walk holds a tree iter, which will become invalid
when we either remove the row that it points to or remove
all rows.
Reset the tree walk in those cases to avoid a crash that
was pointed out by Bastien Nocera.
MacOS provides the NSEventTypeMagnify which is very similar to the
Gtk ZOOM gesture and NSEventTypeRotate which is very similar to the
Gtk Rotate gesture. Those two event sequences are translated to a
sequence of GDK_TOUCHPAD_PINCH events. This sequence is then detected
in the upper gtk layers as Gtk Zoom/Rotate Gestures.

When compressing window state events, we didn't free the discarded

We previously considered any click inside the trough if it
hit an area that the slider might cover. Bring this behavior
back; the trough of scales is otherwise just too narrow to
hit easily with a click.
Consider this bug:
1. Open a file chooser; switch it to $HOME
2. Start typing "~/Dow" with some file that *does* exist in your $HOME
3. Delete the inline-completion selection (e.g. the "nloads" after "~/Down").
4. While you are at "~/Dow_" hit Tab. No completion will occur.
This happens because of the following.
Say the GtkFileChooserEntry is in the process of loading $HOME,
because _set_base_folder() was called. If the entry contains no text,
then the FULL_PATH_COLUMN of the file system model will be set to
unprefixed filenames from $HOME, like
.ssh/
Documents/
Downloads/
somefile.txt
Later we avoid reloading the folder if g_file_equal(old_folder, new_folder).
However, the FULL_PATH_COLUMN gets populated in completion_store_set()
out of the actual filenames that GIO returned, plus the chooser_entry->dir_part.
If the user starts typing "~/Dow" then dir_part changes to "~/", *but*
the folder won't be reloaded since it is also $HOME. However, the completion
machinery assumes that FULL_PATH_COLUMN will contain prefixed entries like
~/.ssh/
~/Documents/
~/Downloads/
~/somefile.txt
So, we add an invariant that chooser_entry->dir_part and
chooser_entry->current_folder_file must change at the same time, and
must not get out of sync: If any of them changes, then the
completions are regenerated.
A gtk_surface.present request was added to gtk_surface which takes
timestamp from some input event, and uses that timestamp to figure out
whether the window can be presented or not. If we don't have a
timestamp, we should just give up instead of making up our own,
otherwise we might steal someones focus.
https://bugzilla.gnome.org/show_bug.cgi?id=763037
The gtk_shell protocol used some half baked unstable protocol semantics
that worked by only allowing binding the exact version of the
interface. This hack is a bit too confusing and it makes it impossible
to do any compatible changes without breaking things.
So, instead rename it to include a number in the interface names. This
way we can add requests and events without causing compatibility issues,
and we can later remove requests and events by bumping the number in
the interface names.
https://bugzilla.gnome.org/show_bug.cgi?id=763001
The adjustment double properties allow values from -G_MAXDOUBLE
to G_MAXDOUBLE, which leads to overflow when calculating
max - min / 10. To avoid that, simply use a fixed page_size of 1.0.
The contents node was not getting state updates at all, and the
trough node was missing some state updates as well, because we
were not calling update_trough_state() in all the places where
it is needed.
This request actually means nothing to the upper GDK layers,
we used to preempt a GDK_SELECTION_REQUEST event, but this is too
eager, and not like things work in X11.
Originally in wayland, this event may be used for feedback purposes.
We however don't perform any mimetype-based feedback, so we can
safely ignored.
This makes data_source_send() the only place where we actually
trigger GDK_SELECTION_REQUEST, this one is conceptually the same
than the X11 selection request event.
...hopefully when needed.
By default I assume a left hand side placement on ltr languages
and the opposite in rtl, for other placements left/right style
classes can be used.
Under Wayland, popovers use subsurfaces, and we end up getting
configure events for these delivered to the toplevel they're in.
To avoid triggering resize loops, ignore configure events that
are not for the toplevel window itself.

The sidebar in the object page was using up more space than it deserves.
Replace it with a combo box in the subheader. Now that we have more space,
put the CSS node tree and the style properties in the same page again.
And add a default color like it was before.
This also fixes other issues with scale values interacting with scale
mark labels, which were buggy at least since 3.18.
When opening the value editor for any GtkAdjustment properties
in the inspector, the popover stretches out for miles, since
it reserves enough space to draw MAXDOUBLE. This is not useful.
Limit the space we reserve to 8 digits.
This removes the event_poll_fd global variable and the (ab)use of
get_default_display. It is also more consistent with other backends.
Also store display
This is not much of a test, tbh. But it will give us a convenient
dump of all GTK+ settings in continuous, which helps with tracking
down test failures that might depend on settings.

One important aspect of non-resizable windows that we need to preserve
is that they shrink when their content requires less size.
Previous changes to allow the default size to be applied to fixed size
windows would have prevented all fixed size windows from shrinking when
their content requires less size.
Allow shrinking for fixed-size windows unless a default size was
specified.
https://bugzilla.gnome.org/show_bug.cgi?id=762974
It does not make sense to pass a for_size into the size allocation
machinery that is smaller than the min-size in that direction.
Warn if it happens, so we can track it down when it occurs.
added a min-height/width compensation too when in fine-tune mode,
so scale with marks and no labels doesn't make the scale node grow
when in fine-tune.
added a scale node padding compensation for the trough growth in
fine-tune mode, so now the scale node doesn't grow anymore when
mark labels are present.
We were failing to do that, leading to progress not disappearing
anymore after it was initially shown, in the gtk3-widget-factory
entry progress example.
Fixes bug 763023: in certain circumstances, XRRGetOutputInfo will return
a null pointer. This commit adds a check to detect and handle this
return value.
If animations are disabled, the only difference we need to make is that
we don't have to start the transition. Size requests should remain the
same.
https://bugzilla.gnome.org/show_bug.cgi?id=762996
Previous commit to address the default size introduced a regression
with fixed size windows if no default size was given, the resulting
window would end up much smaller than its actual content.
kind of a workaround, this approach is pretty unmaintainable, I
hope we'll get a CSS property for spacing directly on the parent
container (a toolbar in this particular case).
See https://bugzilla.gnome.org/show_bug.cgi?id=762397
If a window is not resizable (with gtk_window_set_resizable ()),
the size given with gtk_window_set_default_size() is ignored.
The solution to this would be to use gtk_widget_set_size_request() but
that's a GtkWidget API and therefore does not take into account the
client side decorations when in use with GtkWindow.
Refactor the code so that gtk_window_set_default_size() (which is a
GtkWindow API) gives the expected result on non-resizable windows as
well.

Will make GTK+ more willing to use CSD for all normal windows without
being asked to. Lack of desktop composition will, of course, prevent
it from using CSD (in theory).
GTK_CSD=0 will force CSD to NOT to be used whenever
possible (i.e. in cases where CSD is not specifically requested
by a window, by design).
https://bugzilla.gnome.org/show_bug.cgi?id=759899
Otherwise WM-dependent default cursor is used, which does not
match our theme. Worse, later GDK will realize that we have
our own left_ptr cursor and will apply it after all, making
the discrepancy even more noticeable.

* Explicitly grab the device, setting appropriate cursor on it.
* Fix gdk_device_virtual_set_window_cursor() to just set the
cursor, without trying to check that mouse is over the given
window. Also prevent it from immediately resetting cursor.
* Alse take into account things that happen in other parts of
GDK - don't look for replacement cursor, GDK already did that,
and don't create a default arrow cursor instead of NULL,
GDK-W32 already did that up the stack as well.
Warn about inappropriate cursor == NULL argument instead.

When a gtk_widget_queue_allocate() on some widget increases the clip,
widget->parent's clip was not updated. This appraoch naively just
unions widget's new clip with widget->parent's clip.
This of course only works if widget and parent share the same GDK
window. In the cases where they don't we can't do anything and need a
better fix.
Fixes label-text-shadow-changes-modify-clip.ui reftest.
Toplevels are now true layered windows that are moved,
resized and repainted via UpdateLayeredWindow() API call.
This achieves transparency without any extra effort,
and prevents window size and window contents desychronization
(bug 761629).
This also changes the way CSD windows are detected. We now
use window decorations to detect CSDiness of a window,
and to decide whether a window should be layered (CSD windows should
be) or not.
Decorations are now stored in the window implementation,
not as a quark-based property of the window-as-gobject.

Normally works only on CSD windows, non-CSD windows continue
to use WM modal loop for drag-resizing and drag-moving. However,
if it is activated on non-CSD windows, it does work.
Has the advantage of being completely immune to AeroSnap.
AeroSnap only worked partially on CSD windows, with the only part
that worked being "don't let users drag window titlebar outside of
the desktop". Now AeroSnap doesn't work on windows moved by
this code at all, which is good, since they currently don't work
well with it due to the way shadows are drawn.
It's possible to also re-implement AeroSnap (or something similar),
but that is a story for another commit.
This code was originally intended to fix the problem of window
size and window contents desynchronization, but failed to achieve
that result in the end. Nevertheless, it serves as a foundation for
other changes to the way window resizing works.

key repeat is handled client side, which means stalls in the compositor
dispatching key release events can lead to fictious repeat events.
This commit ties key repeat to a server roundtrip to ensure the client
and server are in sync.
https://bugzilla.gnome.org/show_bug.cgi?id=757942

deliver_key_event is sometimes called from a timeout handler and
sometimes called directly. We currently erroneously return TRUE
(G_SOURCE_CONTINUE) in the case where it's called directly, but to
no ill effect, since we ignore that return value. In the future,
we're going to need to call it directly in other parts of the code
where the return value would be relevant and handling TRUE, would
require adding redundant code.
Instead, this commit just changes the code to always reset the timer
manually, and never rely on glib's ability to automatically reset
the timer by returning TRUE. This makes the code smaller, too, since
there's less special casing required.
https://bugzilla.gnome.org/show_bug.cgi?id=757942
The check is not working for many containers anymore as they are not the
direct parents of their children. We want to allow this behavior in more
places.
We are actually not using the crypt() in GDK-Broadway for quite a while,
so the code implementation for MSVC is actually not used. So, it's time
to get rid of this.
Search also for the headers in include/gio-win32-2.0, as gio.h will
include those headers at some point, and arrange the include paths in a

We create and destroy gadgets inside the levelbar hierarchy here,
and if we don't explicitly remove their CSS nodes from the parent,
they stick around.
According to xdg_shell, an xdg_surface.configure with size 0x0 should
be interpreted as that it is up to the client to set a size.
When transitioning from maximize or fullscreen state, this means the
client should configure its size back to what it was before being
maximize or fullscreen.
This problem currently only occurs on weston because weston sends a
configure with size 0x0 when transitioning back from maximize or
fullscreen.

gdk_display_list_devices is deprecated and all the backends
implement the same fallback by delegating to the device manager
and caching the list (caching it is needed since the method does
not transfer ownership of the container).
The compat code can be shared among all backends and we can
initialize the list lazily only in the case someone calls the
deprecated method.
https://bugzilla.gnome.org/show_bug.cgi?id=762891
The way this method is used from the GtkRange subclasses doesn't really
work well when the slider properties change as a consequence of e.g. a
style class being applied (e.g. the fine-tune style class).
In fact, there's no need to read the minimum slider size out of band,
and we can obtain the same result in a way that always work by setting a
private property on GtkRange.
Since we can use negative margins, we should not use the margin box
for the slider area. Use the border box instead, since that's what is
typically mapped to the visible area.
This commit introduces another node, called "contents", that holds the
main contents of the range. This allows for the main gadget itself to
span across the whole surface of the widget now.
The staging buffer gets allocated any time begin_paint is called
on the window. This can happen even with an empty paint region,
so we should cope with that situation. At the moment we crash
trying to post a runtime warning.

GtkWidget uses gtk_container_foreach() to iterate over children and
check whether they need their allocation reset.
However, that leaves out internal children, such as scrollbars of a
GtkScrolledWindow. Use gtk_container_forall() instead.
gdk_display_add_seat was prepending new seats to the list, which
was effectively making the added seat the new default. Since that
is probably not intended, append to the list.
Setting label-yalign should affect the border gadget, but we need to
compensate for its position by moving the child down or up, depending on
the border gadget's position, so the child never moves.

Except for the init function, all the visual related code is made

we avoid keeping other static variables and instead store the info

It just looks wrong if the file chooser comes up with
"Other Locations" ellipsized. Treat it like the other
fixed entries. We only want to ellipsize bookmarks, because
their length is unpredictable.
We now draw real Windows 95 buttons.
Also split out a draw_edge() function that is supposed to emulate
Windows' DrawEdge() function. I guess we'll need it in other places,
too.
So far, this only reworks the tabs at top implementation.
Windows doesn't have support for theming tabs at left/right/bottom
so we need to figure out what to do there. Wine falls back to
unthemed code.
This is necessary for GtkNotebook so that the stack is always drawn
before the header.
And that is necessary so that the active tab can use negative
margins to overdraw the border of the stack to create a gap and
simulate old GTK2-style visuals for notebooks.
:active is reserved for "mouse button down on node", so we have to use
something else. And stack switcher and radio buttons use :checked for
the active widget, so it makes sense to use :checked for the active tab,
too.
Themes have been adapted.
TODO: Implement :active for tabs.
I am testing GTK+ master against mutter 3.19.90, so I'd

1f74f12d9 rendered entry of keypad decimal mark unuseable for
several national keyboard layouts, this commit amends that, at
least for W32, and makes GTK+ behave more or less the same way
W32 behaves.
The patch works like this:
- When typing the first character at the keyboard or when switching
keyboard layouts, the decimal mark character will be cached in the
static variable "decimal_mark" within gdkkeys-win32.c
- in case of WIN32, gdk_keyval_to_unicode() asks gdkkeys-win32.c for the
current decimal_mark when converting GDK_KEY_KP_Decimal.

1) MSDN says that the coordinates of the maximized window
must be specified as if the window was on the primary display,
even if nearest display where it ends up is not the primary display.
So instead of using nearest display work area verbatim,
use it only to account for taskbar size, while using
primary display top-left corner (0:0) as the reference point.
2) MSDN says that max tracking size is a system property, we
should just call GetSystemMetrics() and use that.

This is a hack because we can't really rtesize the buttons.
Instead, we draw the background only over the area that they would
be drawn if they were drawn by Windows. The button is still selectable
outside of this area, but what can you do...
The way we were adjusting baselines if min-height forces
a size increase was not quite working as intended. Redo
it in a simpler way: just split up the excess and count
half of it for above the baseline and half below.
This fixes button labels in dialogs appearing too low.
It is clearly not the intention that the baseline of icons is at
the very top. The visible effect of this was that spin buttons were
higher than expeted, because the box gadget was trying to line up
the baseline of the text with the top of the buttons, forcing extra
height to be requested.
Just don't set a baseline at all for now.
That would imply the pixelcache monitors the style context for changes
and it doesn't do that.
Its only use case was opacity checks, so add
gtk_pixel_cache_se_is_opaque() instead.
We were updating the whole places sidebar when the trash changed.
This effectively removes all rows and create new ones for every trash
state change.
Although when using GtkTreeView it was somehow ok, with the new
implementation with GtkListBox this effectively locks the UI while the
trash operations are being performed.
When performing operations for i.e. 100 files, the UI can be locked
for more than 1 minute since gvfs-trash usually takes time.
To fix this just update the icon of the trash when the state of the
trash change instead of the whole sidebar.

This adds vendor and product id and axes. This reveals that
the GDK backends have quite different quality when it comes
to returning meaningful information here.
When size_allocate is overridden in widgets, but draw is not,
we can end up drawing a gadget that has not been given a size.

Text handles use to connect to the first GtkScrollable up the hierarchy
so they can be repositioned when scrolling. It makes more sense to look
up the first child of a GtkScrolledWindow, it must be an scrollable too,

text handles.

... if the child is concealed and the transition type is set to NONE.
In this case, both preferred width and preferred height should be 0, but

On Visual Studio, unlike MinGW, manifest files are embedded via
including the manifest file as a resource file in the projects, not
via the .rc file. This means that the line in the .rc file that
specifies the manifest file would cause trouble, so that line gets
removed when the full gtk3-win32.rc is generated on Visual Studio builds,
otherwise 2010+ Visual Studio will complain when compiling the .rc file.
Also, the inclusion of winuser.h will cause warnings during the
compilation of the .rc file.
Fix this by isolating the Win32 resource portions of gtk-win32.rc.in to
gtk-win32.rc.body.in and:
-On MinGW, construct the full gtk-win32.rc by doing the winver.h and
winuser.h inclusion first, then append the contents of gtk-win32.rc.body,
and then appending the line to embed the manifest file.
-On Visual Studio, simply copy the gtk-win32.rc.body to gtk-win32.rc,
and generate the full libgtk3.manifest file.

The first check was the wrong way around.
The second check made the function look wrong. Invalid ID is actually
the special case that should be handled first, so write the function
like that.
We were forcing the size to be at least min-height, but we left the
baselines as they were, which had the effect of making text e.g
in entries 'stick to the top'.
With this change, we adjust the baseline to keep the ratio of
baseline to height unchanged.
The code for adjusting the center widget allocation in case
of uneven sides never worked right in RTL. This was finally
noticed for tabs with close button, which commonly use a
centered label.
The significant change here is a memory leak fix in init_xrandr15.
The rest of the changes makes init_xrandr13 and init_xrandr15 more
parallel, and simplifies init_multihead.
GdTaggedEntry needs that. Though there's probably a bunch of work left
inside GdTaggedEntry to make it look cute again (like storing the area
it reserves for itself to allocate tags in).
Add a gtk_shell.set_startup_id request, so the application can communicate
to the compositor the startup id that it received through the
DESKTOP_STARTUP_ID envvar, or other means.
When running with a Wayland compositor which doesn't support the
xdg_shell interface, gtk+ will segfault while trying to access the
corresponding wl proxy.
Check for xdg_shell support and do not use Wayland if not present, so
that it can fallback to X11, hoping that Xwayland is usable.

we use to animate "all" in the transition, this seems to trigger
some weird gtk sizing issue, restricting the transition to just
the needed properties fixes.
We were notifying when an unmount operation was performed. However,
creating notifications from the gtk+ library is not that expected, and
makes notification handling difficult to do from the application point
of view since we cannot dismiss those notifications.
This cause issues like notifications of unmount drives stay there after
a system reboot, which confuses the user.
Instead of that, remove the notification handling for mount operations
on gtk+ and instead create a new signal on the gtkplacessidebar in order
to inform applications using it about an operation about to start.
Only drawback about this is that the GtkFileChooser loses its
notifications when unmounting, that although we could use the new signal
to do it, we actually don't want to notify from any part of gtk+ for
now.

Some of the translated strings in the cups printbackend are short

message contexts to avoid translation problems.
There is no point in attaching and then committing the same buffer if
there was no damage. This will also make us do less unnecessary backfill
read backs, for the cases where we paint with an empty paint region.
https://bugzilla.gnome.org/show_bug.cgi?id=762120
If a after-paint was scheduled but nothing was painted, for example when
the it was scheduled by a subsurface wanting to update its position,
we'd still try to read back from the backfill cairo surface and update
the committed cairo surface reference even though no buffer was
attached.
Fix this by adding a new state, 'pending_buffer_attached', which is only
true if a buffer was attached during frame. Only when this is true will
the backfill be read back and the committed cairo surface reference be
updated.

The following changes were done to (hopefully) achieve backwards
compatibility while allowing themes to change the size of the indicator.
(1) Deprecate the property.
(2) Change the default value of the property to 0. If it is not 0,
use the property's value for the indicator size. This should make
all programs that actually set it keep the size they set it to.
(3) If set to other values than 0, use min-width/min-height of the
check/radio node to size the indicator. This allows themes to change
the size.
(4) Fall back to the previous default size of 16px. This way themes that
do not set the size keep the same behavior.
...the sizing is still off, waiting for Benjamin to add the magic,
probably the icon shadow is missing, not sure since it's blurry.
This needs to be reverted in case the sizing won't get fixed.
That way we can let ::cancel callers to override the visual
result of the operation (eg. when detaching notebook tabs on
NO_TARGET).
Also, document gdk_drag_drop_done() so it is mentioned that
this is a one-shot call.
https://bugzilla.gnome.org/show_bug.cgi?id=761954
We should conform to a minimal set of reasons for the gtk side to emit
a better GtkDragResult than GTK_DRAG_RESULT_ERROR. This fixes the notebook
tab DnD feature, where we rely on GTK_DRAG_RESULT_NO_TARGET.
In the wayland side, unfortunately we can't honor either NO_TARGET nor
USER_CANCELLED, we don't know of the latter, so we could return false
positives on the former.

Sometimes default tab labels ("Page <n>") get created on-demand,
and in that case, we were forgetting to put them below the tab

heuristics for when to give notebooks background in Adwaita fail
in some cases. So, make sure to always place the label below the
tab node.
