Calling gdk_device_get_direction can trigger a
notify::direction emissions, since the X11 backend
determines the direction on demand. Prevent that by
forcing the direction to be determined ahead of time.

For some of the a11y states, calling gtk_accessible_reset_state
can change the type of the state value from boolean or tristate
to undefined.

Currently, the GdkSurfaceX11 implementation relies that the upper
layers hid the surface before destruction, and that no
GdkSurfaceClass.compute_resize happened between them. If these
circumstances happened, there would be a compute_size timeout left
dangling after the surface got destroyed, poking at incorrect data
later on. Something that looks like this was reported in the
recent mutter-x11-frames "SSD frames server":

It perhaps makes sense to warn in these situations, but either way
it sounds like gdk_surface_x11_finalize() could enforce the correct
behavior by ensuring there is no dangling timeouts/data. This commit
does that.
8455b9ac74 seems to have introduced a problem where we can wind
up focusing no widget at all if the `while (parent)` loop doesn't
find a widget it can successfully move the focus to. This 'fixes'
that by falling back to doing the previous thing if we make it
all the way through that loop without moving the focus. Thanks to
@coreyberla for a hint to improve the implementation.

There's 2 things broken here:
- The mask was calculated on top of the GDK button (i.e. skipping
4-7 buttons), so GDK_BUTTON4_MASK and GDK_BUTTON5_MASK were not
assigned. This is now calculated on the (continuous) BTN_ evcodes
so it is guaranteed that the next 2 physical buttons (i.e.
back/forward) get these two places in the mask assigned.
- Furthermore, these buttons would be pushed to places in the
modifier mask that they didn't belong to. It is now checked hard
that only the first 5 buttons enable a modifier flag.
Overall, this ensures that no event masks with bonkers values are
forwarded, and that no stale implicit grabs are left after additional
buttons are pressed.

We can get spurious focus-out/-in pairs when
the editable label is in a popover that gets
a Wayland keyboard enter event as a result of
clicking the editable label.
A timeout isn't a great solution, but nothing
better is available right now.
Fixes: #4864
Only clear a queued move_focus if the widget
we are focusing is actually visible.
This was happening in some cases when popovers
are dismissed by clicking outside, and it was
causing us to miss proper focus updates that
were already queued.
This partially undoes changes from 3dbf5038fa.
That commit did two things:
1) Move the focus update to after-paint time
2) Change from grabbing focus to the visible parent
to calling move_focus (TAB)
The second part did have the unintended consequence
of moving focus laterally.
Fixes: #4903
Empty/zero bounds are sent by the Wayland compositor if there are no
valid bounds to report, e.g. if there are no connected monitors. Report
this to GTK, which uses this to clamp calculated sizes, as INT_MAX, so
that clamping isn't done until there are actual valid bounds to clamp
to.
This fixes clients sometimes shrinking to their minimum size during
hotplugs or after having suspended the session.
(cherry picked from commit b3a3a6ceb1)
We shouldn't assume there is always a monitor to derive bounds from.
If there is no monitor, pass empty bounds, as this matches what
xdg_toplevel.configure_bounds do in this case.
(cherry picked from commit 148c133674)
Even though the argument is non-nullable, GTK sometimes incurs in that
by itself by destroying the surface while the event is in flight. This
is the case of popping down a GtkDropdown. When this happens we simply
ignore the crossing event, but we should let it through instead, the
compositor did not send it in vain and we possibly still have pointer
state to undo.
Drop the surface checks, so that the event is propagated along GTK.
Doing reset() on the text widgets after commit and delete_surrounding
is still too eager for some IMs (e.g. those that expect being able
to commit text while keeping a preedit buffer shown).
However, reset() is more of a "synchronize state" action on Wayland,
and it is still desirable to do that after changes that do come from
the IM (e.g. requesting the new surrounding text and cursor/anchor
positions). Notably here, the text_input protocol may still come up
with a preedit string after this state synchronization happens.
Shuffle the code so that the text widgets do not reset() the IM
context after text is deleted or committed, but the Wayland IM does
apply its practical effects after these actions happen. This keeps
the Wayland IM fully up-to-date wrt text widget state, while not
altering the ::commit and ::delete-surrounding-text behavior for
other IM context implementations.

The X11 backend can mark modifiers like Shift as consumed even if they
aren't actually active, which seems to be something to do with making
shortcuts like `<Control><Shift>plus` and `<Control>plus` work as
intended regardless of whether the plus symbol is obtained by pressing
Shift and a key (like `+/=` on American, British or French keyboards)
or not (like `*/+` on German keyboards).
However, this can go badly wrong when the modifier is *not* pressed.
For example, terminals normally have separate bindings for `<Control>c`
(send SIGINT) and `<Control><Shift>c` (copy). If we disregard the
consumed modifiers completely, when the X11 backend marks Shift as
consumed, pressing Ctrl+c would send SIGINT *and* copy to the clipboard,
which is not what was intended.
By masking out the members of `consumed` that are not in `state`, we
get the same interpretation for X11 and Wayland, and ensure that
keyboard shortcuts that explicitly mention Shift can only be triggered
while holding Shift. It continues to be possible to trigger keyboard
shortcuts that do not explicitly mention Shift (such as `<Control>plus`)
while holding Shift, if the backend reports Shift as having been
consumed in order to generate the plus keysym.

Commit adba0b97 fixed missed pointer crossings by using a helper function that
was already present and looked like did everything that was needed. However
this function was oriented to keyboard focus and it also did update the related
widget state. Doing these changes on pointer-based crossing was misuse, and
could cause weird interactions with keyboard focus management.
Fix this by using gtkmain.c gtk_synthesize_crossing_event() that is in fact
oriented to pointers.

Instead of passing an event and figuring out coordinates from it, pass
directly the toplevel coordinates so that we can use this outside event
handling.
All callers have been updated to pass the coordinates, in practical effects
they were already based on the GtkNative.
When widgets go mapped/unmapped, we repick but don't generate crossing
events. Since there could be stateful controllers that use those in
the previously picked widget (e.g. GtkEventControllerMotion), skipping
those breaks their state.
Ensure to send the relevant crossing events on every situation that
changes the pointer focus, so these controllers get a fair opportunity
to undo their state.

When reordering notebook tabs, updating the sensitivity state of the
arrow buttons is necessary if the tab is moved to the beginning or

Currently, the wayland IM context sends zwp_text_input_v3.commit from
a number of places, and some of them with partial data. In order to
make client state updates "atomic" and complete, make the communication
happen over an unified notify_im_change() function that happens on
a narrower set of circumstances:
- The GtkIMContext is reset
- The GtkIMContext is just focused
- The gesture to invoke the OSK is triggered
- The IM context is reacting to changes coming from the compositor
Notably, setting the cursor location or the surrounding text do not try
to commit state on their own, and now will be flushed with the corresponding
IM update or reset. But also, these requests won't be prevented from
happening individually on serial mismatch, instead it will be the whole
state commit which is held off.
With these changes in place, all client-side updates are notified
atomically to the compositor under a single .commit request.

We need to free the queued context list in dispose
if we didn't get to register the contexts, and we also
need to free the list properly when we do get to
register them.
This showed up in valgrind as leaked GList structs.
Only the scroll velocity factor is backported here, the scroll unit
event API is notably missing, so this implicitly applies to all smooth
scroll events.
The number also accounts for the 1/10th factor applied in GDK, compared
to the code in main.
Don't return to the main loop, instead force a run of the paint idle.
The paint idle will know to skip all the phases that aren't requested.
This is critically important becuase gdksurface.c assumes the
FLUSH_EVENTS and RESUME_EVENTS phases are matched, and we cannot
guarantee that if we return to the main loop and let various reentrant
code change the frame clock state.
This would lead to bugs with events being paused and never unpaused
again or even crashes.

DnD under Windows needed 3 fixes to work with Gtk.DropTarget.
1. The droptarget_w32format_contentformat_map list never gets
filled so the gdk_win32_drop_read_async throws
"No compatible transfer format found".
This is an easy fix and done the same way in the win32 clipboard code.
2. After a drop no gdk_drop_emit_leave_event gets emitted.
This causes a second drop to trigger a bunch of assertion
'self->drop == drop' failed because the first drop is still active.
This is also an easy fix and done the same way by the macos backend.
3. Handling gdk_drop_status/gdk_drop_get_actions interaction.
In gtk_drop_target_do_drop the code
```gdk_drop_finish (self->drop, gdk_drop_get_actions (self->drop));```
calls the finish operation with the actions of the drop which triggers
```g_return_if_fail (gdk_drag_action_is_unique (action));```
in gdk_drop_finish. The code assumes that GdkDrop::actions gets
narrowed down by calling gdk_drop_status. This is hard to assure
because at the same time gdk_drop_get_actions is used by
gtk_drop_target_accept to figure out if a drag is accepted.
GdkDrop::actions serves a double purpose here as the supported source
actions and the currently agreed on action. Both the x11 and the
wayland backend get this wrong somewhat too. Under wayland/x11 when
a drag coming from a source that supports both MOVE and COPY is
first hovering a drop target that only supports COPY it is afterwards
no longer accepted by other drop targets only accepting MOVE.
Under x11 this is permanent for this drag but with wayland the drag
recovers when hovering other widgets. The win32 backend now sets the
supported source actions before any enter/move/drop and narrows them
down in gdk_win32_drop_status.
The patch only touches the win32 backend and fixes all three issues,
for me restoring DnD under windows.

On Wayland it is a protocol violation to upload buffers with
dimensions that are not an integer multiple of the buffer scale.
Until recently, Mutter did not enforce this. When it started
doing so, some users started seeing crashes in GTK apps because the
cursor theme ended up with e.g. a 15x16 pixel image at scale of 2.
Add a small sanity check for this case.
Not updating shadow size unconditionally would lead to shadow size not
being set on map, which would lead mutter to think that we are a Window
without extents and then become confused when we suddenly set some.
Make sure that doesn't happen by always having shadows set on map, just
like GTK3.

Previously, there was an issue with glitching after showing/hiding a

This allows the user to navigate via tab the links in a label and exits
the widget after the last link, when moving forward, and first link,
when moving backward.
This also ensures that ellipsised links arn't focused.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4681
The `has-tooltip` property gets set to `false` for label with links if no
link is selected. This makes sure to only change the property to `true`
but never to `false`.
Instead of populating the properties right away (when the widget might
not have been allocated yet, and hence cannot know the right values),
the widget should queue an allocation, where it will populate the
values.
For reasons that only apply to the old serial handling, asking for
the surrounding after IM changes resulted in lazy handling of
commit() afterwards.
With the recent interpretation of serials, this problem became more
apparent, since it is in fact very likely that the last interaction
step after an IM change is notifying of the changed surrounding
text after the IM change was applied.
Make handling of surrounding text similar to caret position changes,
always commit() after the state change, but skip through non-changes.
This makes the compositor state fully up-to-date after an IM change.
The gesture as connected currently on the child GtkText is easily overridden
by the parent editables (and gently done so in the attempt to consume all
clicks).
Connect this gesture to the parent editable widget in these cases, so the
gesture can cohabit with the click-consuming one. It's not part of the same
group, but it won't be abruptly cancelled.

This fixes two issues with the offscreen rendering code for nodes with
bounds not aligned with the pixel grid:
1.) When drawing to an offscreen buffer the size of the offscreen buffer
was rounded up, but then later when used as texture the vertices
correspond to the original bounds with the unrounded size. This could
then result in the offscreen texture being drawn onscreen at a slightly
smaller size, which then lead to it being visually shifted and blurry.
This is fixed by adjusting the u/v coordinates to ignore the padding
region in the offscreen texture that got added by the size increase from
rounding.
2.) The viewport used when rendering to the offscreen buffer was not
aligned with the pixel grid for nodes at coordinates not aligned with
the pixel grid. Then because the content of the offscreen buffer is not
aligned with the pixel grid and later when used as textures sampling
from it will result in interpolated values for an onscreen pixel. This
could also result in shifting and blurriness, especially for nested
offscreen rendering at different offsets.
This is fixed by adding similar padding at the beginning of the
texture and also adjusting the u/v coordinates to ignore this region.

We may well be using an EGL context that does not support Desktop (W)GL on
Windows, such as in the case of using libANGLE. So, check whether WGL is
supported for this running instance before trying to query WGL extensions.
This will get rid of warning messages from libepoxy.
Otherwise a stray scroll controller may prevent others from getting hold

WebKit's GTK 4 port can give us textures with an internal format of
GL_RGBA with GL_UNSIGNED_NORMALIZED and a bit-depth of 8. This fixes
warnings for every GdkGLTexture created/delivered to the GskGLRenderer.
The format is essentially the same as GL_RGBA8 since it is normalized
between 0.0..1.0 for 8-bit components.
Fixes#4783
When surface depth switches from non-high-depth to high-depth (or vice
versa) the current surface has to be destroyed before a new one can be
created for this window. eglDestroySurface however was getting passed a
GdkDisplay, rather than the EGLDisplay it expects. As a result the old
surface did not get destroyed and the new surface could not be created
causing rendering to freeze.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4773
If using the opacity CSS property the renderer cannot optimize these
handles without the use of offscreens due to the use of both a border
and rgb render node.
Instead, we can apply the alpha to the color values and get the same
effect in a way that the GL renderer can optimize without the use of
offscreen textures for a sizeable reduction in runtime overhead.
Currently the GtkIMMultiContext may stick to a delegate GtkIMContext
that no longer applies after the multicontext is dissociated from
any widget.
Handle set_client_widget() so that it can handle changes between
widgets from 2 different display, but also so the delegate is made
NULL whenever the context has a NULL widget.
Doing so, any new client widget results in a new delegate IM context
lookup from the right GdkDisplay and GtkSettings, which avoids any
mix up.

Ensure that resolution of the subproject occurs via the dependency
interface, not the "poke at subprojects manually" interface, and make
that actually work via --wrap-mode=forcefallback.
There's no need to mark it as not-required and then manually invoke
subproject(), since fallback should work correctly and it is always
needed.
However, if fallback was performed (or forced) it would error out since
get_variable() was instructed to only use pkg-config while the relevant
variable was exported by the subproject as an internal fallback
dependency.
We had code to do it and it never actually got used correctly. This ensures
that the popup services are attached to the parents so that they get proper
stacking orders when displayed. Additionally, it fixes popups from being
shown as their own windows in Exposé.
If we are clicking through the shadow of a window, we need to take special
care to not raise the old window on mouseUp. This is normally done by the
display server for us, so we need to use the proper API that is public to
handle this (rather than CGSSetWindowTags()). Doing so requires us to
dispatch the event to the NSView and then cancel the activcation from
the mouseDown: event there.
If we closed a key window in response to events, we need to denote another
window as the new key window. This is easiest to do from an idle so that
we don't clobber notification pairs of "did resign"/"did become" key
window.
We have a sorted set of surfaces by display server stacking, so we can
take the first one we come across that is already mapped and re-show it
to become key/main.
If we have server-side decorations we might need to request a layout in
response to the resize notification. We don't need to do this in other
cases because we already handle that in the process of doing the resize
(and that code is that way because of delayed delivery of NSNotification).
If we are using NSWindow titled windows, we don't end up waking up the
frame clock when the window is resized on the display server. This ensures
that we do that after getting a notification of resize.
There are cases we might want to consume a NSEvent without creating a
GdkEvent or passing it along to the NSApplication for processing. This
creates a new value we can use and check against to propagate that without
having to do out parameters at the slightly odd invalid pointer value for
a GdkEvent (similar to how MMAP_FAILED is done).
This can get in the way of how we track changes while events are actively
processing. Instead, we may want to delay this until the next main loop
idle and then check to see if we have a main window as the NSNotification
may have come in right after this.
We want to ensure that we recalculate the sort order of windows before
processing the motion. Generally this would be done in response from the
display server in GdkMacosWindow, but I've seen it possible to race there.
We need to handle the case where we might be racing against an incoming
configure event due to how notifications are queued from the display
server. Rather than calling configure (and possibly causing other things
to move around) this just queries the display server directly for the
coordinates that we care about.
Additionally, we can display:NO as we are in control of all the display
process now using CALayer.
We failed to handle the toplevel with transient-for case here which could
cause our X/Y calculations to be off in other areas such as best monitor
detection.
We do actually need the parent frame clock here because it is the way we
ensure that we get layout called for our popup surfaces at the same time
as the parent surface.
This doesn't appear to happen much, but if it does it is nice to setup
the window placement initially. Generally, transient-for is set after
the creation of the toplevel rather than here.
The GdkMacosBuffer object already has storage for tracking the damage
region as it is used in GdkMacosCairoContext to manually copy regions from
the front buffer to the back buffer. This makes the GdkMacosGLContext also
use that field so that we can easily drop old damage regions when the
buffer is lost. This happens during resizes, monitor changes, etc.
This helper is useful to ensure we are consistent with how we keep a
window clamped to the workarea of a monitor when placing windows on
screen. (This does not affect snap-to-edges).
If _gdk_macos_surface_move_resize() was called with various -1 parameters
we really want to avoid changing anything even if we think we know what
the value might be. Otherwise, we risk messing up in-flight operations that
we have not yet been notified of yet.
This improves the chances we place windows in an appropriate location as
they don't et screwed up before window-manager placement.
We need to bring the application to the foreground in multiple ways, and
this call to [NSApp activateIgnoringOtherApps:YES] ensures that we become
foreground before the first window is opened. Otherwise we end up starting
applications in the background.
Fixes#4736
If we are double buffering surfaces with IOSurface then we need to copy
the area that was damaged in the previous frame to the back buffer. This
can be done with IOSurface but we need to hold the read-only lock so that
we don't cause the underlying IOSurface contents to be invalidated.
Additionally, since this is only used in the context of rendering to a
GdkMacosSurface, we know the life-time of the cairo_surface_t and can
simply lock/unlock the IOSurface buffer from begin_frame/end_frame to have
the buffer flushing semantics we want.
To ensure that we don't over damage, we store the damage in begin_frame
(and copy it) and then subtract it from the next frames damage to determine
the smallest amount we need to copy (taking scale factor into account).
We don't care to modify the damage region to swapBuffers because they
already have the right contents and could potentially fall into another
tile anyway and we'd like to avoid damaging that.
Fixes#4735
This can be used to lock a surface for reading to avoid causing the
surface contents to be invalidated. This is needed when reading back from
a front-buffer to the back-buffer as is needed when using Cairo surfaces
to implement something similar to BufferAge.
Previously, a single CVDisplayLink was used to drive updates for all
surfaces across all monitors. It used a 'best guess' rate which would
allow for updates across monitors of mixed rates. This is undesirable for
situations where you might have a 144hz monitor as it does not allow for
reaching up to that frame rate.
Instead, we want to use a per-monitor CVDisplayLink which will fire at the
rate of the monitor down to the level of updates we require. This commit
does just that.
When a surface crosses onto a new monitor, that monitor is used to drive
the GdkFrameClock.
Fixes#4732
Using the mode allows better detection of refresh rate and refresh
interval for the CVDisplayLink bridge to GdkFrameClock. Using it can help
ensure that our 144hz displays can actually reach that rather than falling
back to just 60hz.
This will also need future commits to rework the displaylink source to be
per-monitor.
When the fingers are placed on the touchpad, we get a scroll event with
the phase NSEventPhaseMayBegin. We can use this to synthesize an is_stop
event. This results in the scrolledwindow stopping scroll with stop
gestures.
This can cause another warning as well, however, which should be addressed
from #4730.
Fixes#4733
Windows can end up on different monitors despite having a parent or
transient-for ancestor. We want them to be driven by the CVDisplayLink
for the best-monitor, and so this needs to be unshared.
Currently we're using a display link that is for all active displays which
is just the display server trying to find some timings that try to overlap
as many as possible.
That was fine for a prototype, but we really need to do better for
situations with mixed frame rate (such as 60hz and 120hz promotion
displays). Additionally, the 144hz external monitor I have will never
reach 144hz using the current design.
This is just the first step in changing this, but the goal is to have
one of these attached to each GdkMacosMonitor which we can then use to
thaw surfaces specific to that monitor.
We will eventually be needing additional feedback from the display server
which would be nice to keep away from the rest of GdkMacosDisplay for
cleanliness sake. Particularly for feedback from mission control and other
environment factors that requires private API for proper integration.
When using server-side-decorations, we need to avoid potential cycles with
compute-size as it may not have the new sizing information yet. We can
just short circuit during "live resize" to get that effect.
Fixes poor window resizing from top-left on titled windows.
This doesn't give us appropriate results if we use the window delegate.
Instead, we need to adjust the frame at the same time we change the
style mask so that we end up in the same location.
Previously we had issues on macos where the overshoot would keep showing.
To fix this we need to actually use discrete events instead of the
generated deltas from macOS in the scroll wheel case. Additionally, we need
to drop the kinetic momentum events from macOS and rely on the gtk kinetic
events which are already happening anyway. We also need to submit the
is_stop event for the GDK_SCROLL_SMOOTH case when we detect it.
To keep the discrete scroll events correct, we need to alter the hack in
gtkscrolledwindow.c to use the same path as other platforms except for
when a smooth scroll event is in place. In the future, I would imagine that
this falls into the boundary of high-precision scrolling and would share
the same code paths as other platforms.
With all of these in place, kinetic scrolling with overshoot appears the
same on macOS as other platforms.
When creating new windows, it is better if we create them with a slight
offset to where they were created before so that they are visible to the
user separately from what they might be overshadowing.
We were missing the surface offset (e.g. shadows) at the time of expressing
the text caret location in surface coordinates. Add this offset so the
coordinates are as expected by the compositor.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4668
Tools like gtk4-launch can't set surface on the activation token so
don't require it. If the compositor requires it we can't do anything
about it anyway. This avoids a critical:
(gtk4-launch:23497): Gdk-CRITICAL **: 17:07:24.704: gdk_wayland_surface_get_wl_surface: assertion 'GDK_IS_WAYLAND_SURFACE (surface)' failed
Fixes: be4216e051 ("gdk/wayland: Support the xdg-activation wayland protocol")
Signed-off-by: Guido Günther <agx@sigxcpu.org>
Currently, we have all the plumbing in place so that GTK consumes the
startup notification ID when focusing a window through the xdg-activation
protocol.
This however misses the case that a window might be requested to be
focused with no startup ID (i.e. via interaction with the application,
not through GApplication or other application launching logic).
In this case, we let the application create a token that will be
consumed by itself. The serial used is that from the last
interaction, so the compositor will still be able to do focus prevention
logic if it applies.
Since we already do have a last serial at hand, prefer xdg-activation
all the way over the now stale gtk-shell focusing support. The timestamp
argument becomes unused, but that is a weak argument to prefer the
private protocol over the standard one. The gtk-shell protocol support
is so far left for interaction with older Mutter.
The simplify and validate commands can function
without a display connection, only preview absolutely
needs one. Allow this, by using gtk_init_check().
The trickery we do with objcopy and ld to speed up
resource inclusion does not seem to work right on
32bit Arm, so just skip it there.

This one can be used for both premultiplied and non-premultiplied alpha
formats, since alpha is always 255. It is useful for opaque PNG upload
on both cairo and GL renderers.
That way, all permutations are possible. Previously it was only useful
in the cairo renderer, which required rgba8 → premultiplied bgra8, while
the GL renderer required rgba8 → premultiplied rgba8. Now both are
available.
This was only useful when building for AArch32 without -mfpu=neon, on
AArch64 or with -mfpu=neon gcc is smart enough to do the auto-
vectorisation, leading to code almost as good as what I wrote in
1fdf5b7cf8.
It appears that NVIDIA does not implement EGL_EXT_swap_buffers_with_damage
on their EGL implementation, but does implement the KHR variant of it.
This checks for a suitable implementation and stores a pointer to the
compatible implementation within the GdkGLContextPrivate struct.
We were looking at GtkWidget:has-focus from
event controller signal handlers here, but
the widget property is only changed after
the event controllers.
Update the :has-focus property of the focus
widget when the active status of the window
changes.
We change the property after generating the
GDK_CROSSING_ACTIVE crossing events.
This may come from different sources at around the same time, e.g.
a hold gesture while on overshoot. Avoid doing that if an
animation is already set.

When large viewports are passed to gsk_renderer_render_texture(), don't
fail (or even return NULL).
Instead, draw multiple tiles and assemble them into a memory texture.

CI currently fails with "fatal error LNK1318: Unexpected PDB error; OK (0) ''"
Google tells me it might be related to hitting a memory limit. Let's try
disabling debug for now.
Instead of performing keyboard layout substitution whenever we find a matching

This broke with the previous fixes for initial window positioning. We need
the initial positioning so that tails will be displayed correctly when the
popover surface is displayed.
If the size changes, we need to relayout the tiles. Otherwise we can keep
using what we had before. Generally, that shouldn't happen, but the
previous check was failing in a number of ways.
It looks like, particularly on the M1, we might need to double buffer the
contents of the IOSurface<->OpenGL texture bindings. This doesn't appear
to show up on the Intel macbooks I've tried, but I've seen it in the wild
on an M1.
If we have a 2x scale laptop with a 1x scale external display, we would
need to create a new IOSurface for the external display once it crosses
a boundary, otherwise we won't have something capable of displaying
correctly on the second monitor.
This provides a major shift in how we draw both when accelerated OpenGL
as well as software rendering with Cairo. In short, it uses tiles of Core
Animation's CALayer to display contents from an OpenGL or Cairo rendering
so that the window can provide partial damage updates. Partial damage is
not generally available when using OpenGL as the whole buffer is flipped
even if you only submitted a small change using a scissor rect.
Thankfully, this speeds up Cairo rendering a bit too by using IOSurface to
upload contents to the display server. We use the tiling system we do for
OpenGL which reduces overall complexity and differences between them.
A New Buffer
============
GdkMacosBuffer is a wrapper around an IOSurfaceRef. The term buffer was
used because 1) surface is already used and 2) it loosely maps to a
front/back buffer semantic.
However, it appears that IOSurfaceRef contents are being retained in
some fashion (likely in the compositor result) so we can update the same
IOSurfaceRef without flipping as long as we're fast. This appears to be
what Chromium does as well, but Firefox uses two IOSurfaceRef and flips
between them. We would like to avoid two surfaces because it doubles the
GPU VRAM requirements of the application.
Changes to Windows
==================
Previously, the NSWindow would dynamically change between different
types of NSView based on the renderer being used. This is no longer
necessary as we just have a single NSView type, GdkMacosView, which
inherits from GdkMacosBaseView just to keep the tedius stuff separate
from the machinery of GdkMacosView. We can merge those someday if we
are okay with that.
Changes to Views
================
GdkMacosCairoView, GdkMacosCairoSubView, GdkMacosGLView have all been
removed and replaced with GdkMacosView. This new view has a single
CALayer (GdkMacosLayer) attached to it which itself has sublayers.
The contents of the CALayer is populated with an IOSurfaceRef which
we allocated with the GdkMacosSurface. The surface is replaced when
the NSWindow resizes.
Changes to Layers
=================
We now have a dedicated GdkMacosLayer which contains sublayers of
GdkMacosTile. The tile has a maximum size of 128x128 pixels in device
units.
The GdkMacosTile is partitioned by splitting both the transparent
region (window bounds minus opaque area) and then by splitting the
opaque area.
A tile has either translucent contents (and therefore is not opaque) or
has opaque contents (and therefore is opaque). An opaque tile never
contains transparent contents. As such, the opaque tiles contain a black
background so that Core Animation will consider the tile's bounds as
opaque. This can be verified with "Quartz Debug -> Show opaque regions".
Changes to Cairo
================
GTK 4 cannot currently use cairo-quartz because of how CSS borders are
rendered. It simply causes errors in the cairo_quartz_surface_t backend.
Since we are restricted to using cairo_image_surface_t (which happens to
be faster anyway) we can use the IOSurfaceBaseAddress() to obtain a
mapping of the IOSurfaceRef in user-space. It always uses BGRA 32-bit
with alpha channel even if we will discard the alpha channel as that is
necessary to hit the fast paths in other parts of the platform. Note
that while Cairo says CAIRO_FORMAT_ARGB32, it is really 32-bit BGRA on
little-endian as we expect.
OpenGL will render flipped (Quartz Native Co-ordinates) while Cairo
renders with 0,O in the top-left. We could use cairo_translate() and
cairo_scale() to reverse this, but it looks like some cairo things may
not look quite as right if we do so. To reduce the chances of one-off
bugs this continues to draw as Cairo would normally, but instead uses
an CGAffineTransform in the tiles and some CGRect translation when
swapping buffers to get the same effect.
Changes to OpenGL
=================
To simplify things, removal of all NSOpenGL* related components have
been removed and we strictly use the Core GL (CGL*) API. This probably
should have been done long ago anyay.
Most examples found in the browsers to use IOSurfaceRef with OpenGL are
using Legacy GL and there is still work underway to make this fit in
with the rest of how the GSK GL renderer works.
Since IOSurfaceRef bound to a texture/framebuffer will not have a
default framebuffer ID of 0, we needed to add a default framebuffer id
to the GdkGLContext. GskGLRenderer can use this to setup the command
queue in such a way that our IOSurface destination has been
glBindFramebuffer() as if it were the default drawable.
This stuff is pretty slight-of-hand, so where things are and what needs
flushing when and where has been a bit of an experiment to see what
actually works to get synchronization across subsystems.
Efficient Damages
=================
After we draw with Cairo, we unlock the IOSurfaceRef and the contents
are uploaded to the GPU. To make the contents visible to the app,
we must clear the tiles contents with `layer.contents=nil;` and then
re-apply the IOSurfaceRef. Since the buffer has likely not changed, we
only do this if the tile overlaps the damage region.
This gives the effect of having more tightly controlled damage regions
even though updating the layer would damage be the whole window (as it
is with OpenGL/Metal today with the exception of scissor-rect).
This too can be verified usign "Quartz Debug -> Flash screen udpates".
Frame Synchronized Resize
=========================
In GTK 4, we have the ability to perform sizing changes from compute-size
during the layout phase. Since the macOS backend already tracks window
resizes manually, we can avoid doing the setFrame: immediately and instead
do it within the frame clock's layout phase.
Doing so gives us vastly better resize experience as we're more likely to
get the size-change and updated-contents in the same frame on screen. It
makes things feel "connected" in a way they weren't before.
Some additional effort to tweak gravity during the process is also
necessary but we were already doing that in the GTK 4 backend.
Backporting
===========
The design here has made an attempt to make it possible to backport by
keeping GdkMacosBuffer, GdkMacosLayer, and GdkMacosTile fairly
independent. There may be an opportunity to integrate this into GTK 3's
quartz backend with a fair bit of work. Doing so could improve the
situation for applications which are damage-rich such as The GIMP.
There are situations where our "default framebuffer" is not actually
zero, yet we still want to apply a scissor rect.
Generally, 0 is the default framebuffer. But on platforms where we need
to bind a platform-specific feature to a GL_FRAMEBUFFER, we might have a
default that is not 0. For example, on macOS we bind an IOSurfaceRef to
a GL_TEXTURE_RECTANGLE which then is assigned as the backing store for a
framebuffer. This is different than using gsk_gl_renderer_render_texture()
in that we don't want to incur an extra copy to the destination surface
nor do we even have a way to pass a texture_id into render_texture().
The GtkFileCHooserNativeQuartz injects a NSComboBox into the NSSavePanel
(which is displayed in a remote process since 10.15 whether or not you are
a sandboxed application). The style has changed and we need more space
here to not clip part of the combobox out of view.
I tried every size from 22 to 30 and this seemed to look the most natural
without skewing the location of the text within the combobox.
Previously, the popover would cause the window to go into the :backdrop
state which is not what we want for consistency with other platforms. This
fixes that by walking up the surface chain when we get notified of
loosing or acquiring "key" input from the display server.
If the rendering operation is over an opaque region, we can potentially
avoid clearing a large section of the framebuffer destination. Some cases
you do want to clear, such as when clearing the whole contents as some
drivers have fast paths for that to avoid bringing data back into the
framebuffer.
One may be using IJG libjpeg or libjpeg-turbo to build GTK, and their
build files may or may not generate pkg-config files for us. To make
things easier, we can make use of CMake's built-in support for finding
IJG libjpeg or libjpeg-turbo.
The CMake build files for libtiff may or may not generate pkg-config
files for us, so we can use Meson's CMake support to help us find
libtiff, as CMake has built-in support for finding libtiff.
Add a variable in meson.build that covers Visual Studio-like compilers,
so that we can use it to help us find depedencies using CMake rather
than via pkg-config, where applicable.
Change the existing use case for finding libpng accordingly.
We might have panels with controls in them where the window is running in
another process. The control could have a wrapper window which we would
see from this process. This can happen with the GtkFileChooserNative, but
any NSSavePanel in macOS 10.15+ is out of process (not just sandboxed
applications).
This significantly cleans up how we handle various move-resize, compute-
size, and configure (notification of changes) in the macOS GDK backend.
Originally when prototyping this backend, there were some bits that came
over from the quartz backend and some bits which did not. It got confusing
and so this makes an attempt to knock down all that technical debt.
It is much simpler now in that the GdkMacosSurface makes requests of the
GdkMacosWindow, and the GdkMacosWindow notifies the GdkMacosSurface of
changes that happen.
User resizes are delayed until the next compute-size so that we are much
closer to the layout phase, reducing chances for in-between frames.
This also improves the situation of leaving maximized state so that a
grab and drag feels like you'd expect on other platforms.
I removed the opacity hack we had in before, because that is all coming
out anyway and it's a bit obnoxious to maintain through the async flows
here.
This fixes GTK's NSWindow for toplevels so that they are allowed to enter
fullscreen. We were already handlign the state transitions from the
setStyleMask: halper, but we didn't previously tell the window we are
allowed to transition into that.
There is a bit of a mismatch here in that GTK doesn't have any such flag
that determines if a window is "allowed" by policy to enter fullscreen
since window managers on Linux are free to do that at will.
This makes it easier to figure out those values (which are mentioned in
the GtkApplication documentation) rather than working that out from the
way they're generated (or documented as being generated).
If we have GStreamer on macOS we likely have support for CGL to get an
OpenGL context we can use. This provides the missing pieces to get
accelerated video playback in gtk4-widget-factory working.
This more than halves the total runtime of this function since the
previous commit, from 8.36% to 4.02%, and is most likely memory
bandwidth limited on this specific board now.
I tried to do a SSE2 version as well, but couldn’t find any equivalent
of the LD4/ST4 ARM instruction.
On x86 on a Kaby Lake CPU, this makes it go from 6.63% of the total
execution time (loading some PNGs using the cairo backend) down to
3.20%.
On ARM on a Cortex-A7, on the same workload, this makes it go from 57%
to 8.36%.
We want our tracking area to be limited to the input region so that we
don't pass along events outside of them for the window. This improves the
chances we click-out of a popover with a large shadow.
This still doesn't let us pass-through clicks for large shadows on top-
level windows though.
We only should be asserting in static functions. Furthermore, this function
did not need to have GDK_BEGIN_MACOS_ALLOC_POOL as nothing is being
allocated there which would cause pooling to get used.
This needs to handle the boundary case where the value is exactly equal
to the edge of a rectangle (which gdk_rectangle_contains_point() does not
consider to be containing). However, if there is a monitor in the list
that is a better match, we still want to prefer it.
When using an external mouse on MacOS, the scrolling behavior is
reversed from the user's scrolling preference. Additionally, it is
noticeably sluggish.
This commit fixes both issues by negating the deltas and multiplying
them by 32 before constructing a new scroll event. 32 seems to be the
"traditional" scaling factor according to [Druid], but I'm not sure
where that value actually comes from. Regardless, scaling the deltas by
this amount makes scrolling feel a lot more responsive in the GTK demos.
Scrolling with a trackpad is not affected by either issue because it
triggers a different code path that uses more precise deltas, and
already negates them.

We currently list everything as a dependencies, regardless of whether
it actually is; this is a source of confusion for users that read the
GTK documentation.
Gi-docgen has a new "related" key in the project configuration which
allows us to list libraries that are merely related to the namespace
we are documenting; the "dependencies" key is used to document the
actual namespace dependencies, now.
This was causing us to draw the same background content twice which is a
significant amount of bits to flip in the GPU for maximized windows,
especially twice.
This updates GtkPopover to use the new GtkNative abstraction for
reporting opaque regions of the window, in hopes that it can speed
up compositors for things like animated lists, menu transitions,
and more.
Fixes#4689
This switches to using the new GtkNative machinery for updating the
opaque region. Some amount of local calculation is still required for
determining when we should apply shadows, and this inherits what was
done previous for that.
Related #4689
This abstracts the machinery to update the opaque region for a GtkWindow
into GtkNative so it may be used from other native impelementations such
as GtkPopover.

Some Windows keymaps have bogus mappings for the Ctrl modifier. !4423 attempted
to fix this by ignoring the Ctrl layer, but that was not enough. We also need to
ignore combinations of Ctrl with other modifiers, i.e. Ctrl + Shift. For example,
Ctrl + Shift + 6 is mapped to the character 0x1E on a US keyboard (but it should
be treated as Ctrl + ^). Basically, always ignore Ctrl unless it is used in
conjunction with Alt, i.e. as part of AltGr.

We don't want to risk having something really weird come out if we have a
WCG colorspace, so instead only do the performance hack on systems where
the output is likely reasonable.
We will want to eventually just be drawing in the appropriate colorspace,
but that is not available yet.
When using software rendering w/ cairo, assume we're drawing in
the best-monitor's colorspace rather than RGB to avoid colorspace
conversions on every frame.
Instead of relying on cairo_t to perform drawing from our backing
image surface to the Core Graphics context, we can convert the
cairo_image_surface_t into a CGImageRef without having to copy
data if we are certain of the alignment of the image up front.
Without this, there are many situations, based on the size of the
window that could cause cairo to take a slow path and malloc/copy
the data to ensure that alignment.
The previous commit titled "macos: align image surface rowstride to
16-bytes" ensures that this invariant is true so that our drawing
code can assume we can reference the framebuffer from the
cairo_image_surface_t using a CGDataProvider.
Since GdkMacosCairoContext and GdkMacosCairoSubview are coordinating,
we can also setup the transformation/scale early when drawing the
cairo_image_surface_t instead of when copying it to Core Graphics.
Furthermore, the CGImageRef is created with an RGB colorspace so
that we are not performing colorspace conversion to the output
device. We don't get color matching between displays, but we don't
expect that anyway, particularly with the software renderer.
When creating a cairo_image_surface_t we want both the framebuffer pointer
and each row to be aligned to 16-bytes so that Core Graphics will use more
optimal paths.
However, cairo_image_surface_create() will not guarantee that the rowstride
is aligned to 16-bytes so we must do that ourselves.
We need to avoid conflating the managing of frame callbacks from
the freeze/thaw mechanics and ensure we don't perform extra thaw
requests at the wrong time.
Some keymaps on Windows contain bogus mappings for Ctrl+key for certain
keys, e.g. Ctrl+Backspace = Delete, or Ctrl+[ = 0x1B. These are never
used on Windows, so we should ignore them.
Fixes#4667
GTK's old key symbol list is missing a few symbols like the per mille
sign that is included in some keyboard layouts. This commit updates
gdkkeyuni.c to match libxkbcommon's current key symbol list.
From the GCC manpage:
> Wimplicit-fallthrough=5 doesn't recognize any comments as
> fallthrough comments, only attributes disable
> the warning.
So, check for the =5 version after checking for the simple version. This
way we get -Wfallhrough with clang and -Wfallthrough -Wfallthrough=5
with GCC, which works.
Hold gestures are used to bring existing gestures on touchpad
semantically closer to touchscreen gestures.
Touchpad gestures observe hold gestures with a matching amount of
fingers and emit their begin and end signals when fingers are detected
or removed on/from the touchpad.
When a hold cancel event is detected, it is required to wait a few
milliseconds until the next event(s) are received to avoid emitting
multiple begin signals.
Part-of: <!3454>
Handle hold events:
- GDK_TOUCHPAD_GESTURE_PHASE_BEGIN: scroll-begin is emitted.
- GDK_TOUCHPAD_GESTURE_PHASE_END: A hold gesture ends only when all
fingers are lifted from the touchpad without movement, so
scroll-end is emitted right away.
- GDK_TOUCHPAD_GESTURE_PHASE_CANCEL: A hold gesture is cancelled when
some fingers are lifted/put down or movement is detected. In this
case, scroll-end is emitted after a small timeout only if
GDK_SCROLL wasn't detected.
Part-of: <!3454>
Since the addition of GdkEventSequence in touchpad events, these
are now stored in the gesture using that sequence. This bit of touchpad
gesture handling was however missing to be updated, still looking up
the special NULL sequence.
Use the last sequence here, which will be the one coming from touchpad
gesture events.
Despite touchpad gestures having a sequence, these must use the logical
pointer focus. Avoid using the sequence for GtkPointerFocus lookups with
those events, in order to ensure those events make it all the way to the
intended target.
This is fallout from adding GdkEventSequence information to touchpad
gestures.
This change is done for 2 reasons:
- The logic to request this phase when compressing scroll events is
slightly broken. If there are multiple scroll events that are
coalesced into one, the surface frame clock will not get this request.
The worst case is having >= 2 scroll events on every frame, as the
compressed event will be left in the queue, and be further compressed
on future events.
- Even scroll events aside, this phase is requested in oddly specific
places that are not enough to cover all events, others do rely on
unrelated GdkFrameClock activity that happens to flush the events
as well.
Unify this phase request so it explicitly happens on the arrival of any
event. This ensures that events (compressed or not) will be handled
promptly after arrival.
Currently when the widget is realized after the focus in event the input
method isn't activated as enable is never sent. The call trace is
gtk_text_focus_changed ->
gtk_im_context_focus_in ->
gtk_im_context_wayland_focus_in
which returns early as self->widget is NULL since it's set up in
gtk_text_realize() via gtk_im_context_set_client_widget(). Handle that
case by invoking gtk_im_context_focus_in() from gtk_text_realize() too.
A case where the above happens is a GtkSearchEntry in a GtkSearchBar.
E.g. in gtk4-demo when starting the demo and then hitting the search
button right away.
Remember the current context on focus-in even though the text-input
isn't set up yet. This helps in the case where the text-input is not yet
created but a widget already got focused. Without that the enable()
invocation in text_input_enter() woulnd't be invoked leaving the input
method disabled.
This fixes
gtk4-demo --run=search_entry
which would initially not show the on-screen keyboard when e.g using
phoc/sway as compositor.
As per Benjamin's suggestions, cleanup the previous implementation on
initializing the GLES context on Windows, so that we use more items that are
already in GDK proper and integrate two functions into one.
Instead of first trying to explicitly ask for a WGL 4.1 context, ask for
the WGL context version that matches what is reported via
epoxy_gl_version(), so that we get the maximum WGL version that is
supported by the graphics drivers, and make sure any WGL contexts that
are shared with this (initial) WGL context are created likewise.
We can try to do a default-bog-standard 3.2 core WGL context creation
if the need arises, but let's leave that alone for now.
The EGL context that we are actually creating must have matching OpenGL/ES
versions and allowed GL API set with the previously-created EGL context
that will be shared with it so that they can interoperate together, if
applicable.
This will fix the situation by making sure that we request for the
OpenGL/ES version and OpenGL API set that match with what we have in our shared
EGL context. Otherwise, the newly-created EGL context assumed a OpenGL/ES 2.0
context that supported desktop OpenGL, which may not be what we wanted, such as
in the case of libANGLE.
We are now able to create EGL contexts properly on Windows, but not GLES. This
tries to fix things by doing the following:
* Record the GL context type in a more proper fashion, using an Enum. This
makes things a bit cleaner.
* Force GLES-3.0+ contexts, since libANGLE requires this to properly work with
the shaders-its 2.0 contexts don't work well with our shaders.
Since now we have the shaders working on Windows under GLES with libANGLE using
a 3.0+ context, drop the check to fall back to the Cairo renderer when GLES is
being used.
We only save the size when we transition from floating to fixed, so that
we can restore the size to the one prior to being fixed.
However, we should not restore to this size whenever we see a 0x0 size
from xdg_toplevel, as it can do that any time it doesn't care about the
size, e.g. when the surface is floating and just changing state.
Fix this by only using the saved size when transitioning from fixed to
floating, not when staying floating while previously floating.

Make GtkIMContextIME ignore ASCII control characters just like other
IMContext implementations (e.G. GtkIMContextSimple). Fixes bogus
characters appearing in text input fields (old bug 676077).
The actual code that does the IM context code handling on Windows now uses the
native Windows APIs to handle keystrokes, so this patch is no longer needed, as
it was found that it instead caused issues.

This reverts commit fd6ce9975e.
gdk_wayland_toplevel_inhibit_idle() contained a contradictory assert
that always fail. More specifically, in the branch that is supposed to
create the idle inhibitor, there is an assertion that it must already
exist and that the refcount must be greater than zero. This causes a
crash on WMs/DEs that use the ZWP idle inhibit manager protocol such as
KDE Plasma and Sway. Fix this by just asserting that the refcount is
zero instead.
GtkBuilder uses GMarkup, which defines a boolean attribute value as:
- yes/no
- true/false
- 1/0
The ITS file for GtkBuilder UI definitions is only using the first pair,
likely because Glade only ever used those values. GTK's own tools, though,
will typically simplify the full yes/no and true/false strings to 1 and 0,
to minimise the parsing time.

Various transforms are normalized with their next transform, and if they
end up being the identity transform will return NULL.
For example a translation by (x,y,z) and followed by (-x,-y,-z) will
result in NULL.
This makes the hotspot of DND surfaces work when using the Vulkan and
OpenGL renderers.
This bumps the CI image used to the newly built image. This is needed to
install a new enough libwayland-client.so needed for wl_surface.offset.
This is done by adding wayland as a meson subproject, building it
on-demand if the version in the system is not new enough. As
libwayland-client.so is pulled in implicitly when linking to gtk4, the
compile step needs LD_LIBRARY_PATH set to make ld find the right library
to link to.
For some users, GetKeyboardLayoutNameA() returns an alias instead of the
fully resolved keyboard layout identifier. In that case, we have to
query the registry to resolve the alias before we can look up the DLL
path.

Contrary to what you can read on the internet, SGCAPS keys don't work
by having capslock toggle the KBDCTRL bit, they actually have two
consecutive table entries, the first of which is for the normal
version and the second of which is for the capslocked version.
Background: SGCAPS is short for Swiss German caps because Swiss German
was the first layout to use this feature. For keys with the SGCAPS flag,
capslock has a different effect than pressing shift. For example:
Shift + ü = è, CapsLock + ü = Ü, CapsLock + Shift + ü = È
DLL loading failures should not happen under normal circumstances, but
we should at least try not to crash and and print better diagnostic
messages if they do happen.
See https://gitlab.gnome.org/GNOME/gtk/-/issues/4610
Previously, we treated CapsLock and KanaLock as part of the global
keyboard state, much like NumLock and ScrollLock, rather than using
the supplied modifier mask. This was because GDK does not have a
modifier mask for KanaLock, only for CapsLock, so it would not have been
possible to properly support it.
However, this approach ended up causing problems, with certain keyboard
shortcuts not registering when capslock was active. This was first
observed in Inkscape [0] and appears to affect shortcuts consisting of a
single key (like 'a') with no additional modifiers (wheareas shortcuts
like 'ctrl+a' work).
So now we are using the supplied GDK_LOCK_MASK instead, and dropped
support for KanaLock, which we probably don't need anyway (since regular
text input should be handled by the IME input module -- the keymap is
mainly for shortcuts and keybindings, where you don't really want
KanaLock).

We are no longer using PangoFT2 APIs in this demo, so make sure that we build

Like what was done on gtk/language-names.c, acquire the language names via the
native Windows NLS APIs, eliminating a run-time dependency on iso-codes on
Windows.
Instead of relying on the iso-codes package, use the native Windows NLS APIs to
acquire the localized (translated) language names so that we do not need to
incur an extra runtime dependency on Windows. It's not coverering 100% of the
languages that we would like to support through this, but should cover much of
the things that are required.
We aren't really using PangoFT2 for [language|script]-names.c, and are
always using items from them, so make sure they are being built.
Also always include the pangoft2 dependency in gtk_dep if it is found.

Without building the demos, nothing gets installed into $prefix/share/icons/hicolor. Which makes running

libpng wants to receive samples in either RGB or RGBA order, whether
each sample is big-endian or not. This resolves test failures in

Modifying the test to show the color in use and write out the PNG bytes
to a file, and running the memorytexture test on s390x, produces a PNG
that loads with the correct color values in GIMP (on an x86_64 machine),
which seems like evidence that this is the correct change and not just
compensating errors.

If we have a GDK_ACTION_MOVE, we need to delete the selection. However,
previously this only worked when the drop target and drag source were

Instead, we stash marks for the duration of the operation so that we can
delete the appropriate selection when completing the move.
That way we ensure that the GL context(s) get disposed, which they
previously weren't due to them still being the current context.
This also implicitly adds testing of gLContext destruction, which
previously wasn't ever done by any test.

If the application window is measured with for_size -1 horizontally,
this code clearly passes something lower to the parent class measure()

This has lots of issues:

But it's better than nothing, so better get it committed.
After performing an action such as undo/redo, we need to actually scroll
to the position where the operation occurred.
I do note that the scroll here seems to often get invalidated if it is
pages away, and we never make the full scroll. But I've seen this all over
the place elsewhere too and that needs to be handled, most likely, as a
more comprehensive fix for scrolling during line validation.

We finish the write to the output stream long after the stream has been

We also use that property to always request flushes when the stream is

We need to be very careful when writing data, because if we aren't, sync
functions will be called on the output stream and X11 does not like that

significant amount of memory when called a lot.
That said, it shouldn't be getting called this much but given the current
state of affairs elsewhere in GtkActionMuxer, this brought temporary
allocations down from 9MiB to 9KiB in gnome-text-editor after showing
the context menu a few times.

I saw this coming across through a ffi boundary in Sysprof, and we wanted
to keep most things within GDK using native marshalling to improve
profiler results when frame pointers are not used.
Instead of allocation width for height for width for height or whatever
that code was doing, actually allocate the size we were given or the
requested size, whatever is larger.
Don't just pass on measure() calls, but actually behave in the way we
behave during size allocate.
This should improve cases where GtkScrolledWindow is used with GTK_POLICY_NEVER.
When loading .mp3 files the duration is initially unknown. Before this
change it was reported as a large integer (since GST_CLOCK_TIME_NONE is
-1). Now it's correctly reported as 0.
We want this to take precedence in the wayland platform to other
modules that might be loaded via the IO extension point. None of
those is going to bode well in this platform.

When returning surrounding context to input methods,

Update the affected input method tests.
For libANGLE to work with our shaders, we must use "300 es" for
the #version directive in our shaders, as well as using the non-legacy/
non-GLES codepath in the shaders. In order to check whether we are
using the GLSL 300 es shaders, we check whether we are using a GLES 3.0+
context. As a result, make ->glsl_version a const char* and make sure
the existing shader version macros are defined apprpriately, and add a
new macro for the "300 es" shader version string.
This will allow the gtk4 programs to run under Windows using EGL via
libANGLE. Some of the GL demos won't work for now, but at least this
makes things a lot better for using GL-accelerated graphics under Windows
for those that want to or need to use libANGLE (such as those with
graphics drivers that aren't capable of our Desktop (W)GL requirements in
GTK.
.. when creating the surface (with the HWND associated with the
newly-created surface) as well as destroying the surface (with NULL,
since the HWND is going to be destroyed), so that we can tie the EGL
calls to the HWND that we want to do the EGL stuff.
If we set the placeholder text before setting a buffer, we end up with
both the placeholder *and* the buffer's contents visible at the same

We use gtk_gesture_get_last_event() underneath at places that need to
work during ::proximity emission. Since GtkGesture only tracks events
while there are button/touch presses involved, this is not going to
bring the right result there.
Use gtk_event_controller_get_current_event() consistently inside,
which always pokes at the event being handled (which is the correct
intent here).
In some circumstances (e.g. activating with a stylus something that
closes a window), we can receive zwp_tablet_tool.proximity_out without
receiving a zwp_tablet_tool.up beforehand.
In those cases, we are not expecting neither .up nor .button, so
reset the stylus device button modifiers on proximity_out.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/4103
We are looking up the seat logical pointer modifiers (i.e. the wl_pointer),
not the ones for the tablet tool device. This breaks accounting further
along in GTK leaving stuck implicit grabs.

The idea of within-margin is to scroll as little
as possible to bring the mark within the margins
defined by the factor. The code was achieving
that when scrolling down, but not when scrolling
up. This change makes things symmetrical.
Fixes: #4325
Update the functions that were updated in the previous commit to have all
GdkSurface variables named as 'surface' instead of the GTK-3.x-era window, to
make things more consistent across the board. Also fix formatting a bit.
Make the toplevel surface respond to size computations unless it is just being
created, or maximized, made fullscreen or underwent an AeroSnap operation.
This will ensure that the surface size is properly computed in time, so that
surfaces can be resized as needed.
This will fix issues 3728 and 3799.
On Windows with nVidia drivers at least, when we create a legacy context
via wglCreateContext(), we may still get a (W)GL 4.x context. Allow
such contexts to also use GLSL version 130 instead of 110, so that
things do continue to work.
It turns out we can't just use the size returned
by the memory stream as-is, since it may contain
unfilled garbage at the end, which utf8 validation
will choke on. So, cut it off at the first '\0'
we find.
When the iter is at the end of the buffer,
gtk_text_view_get_iter_location returns a
rectangle with width 0, which in turn makes
gdk_rectangle_intersect return FALSE.
Avoid that by always giving the rectangle
non-empty dimensions.
Fixes: #4503
As far as I can tell, the code here is redundant and probably ended up
this way for historical reasons. A drag surface without
`->is_drag_surface` would be created if `gdk_display_create_surface`
were called with `GDK_SURFACE_TEMP`, but drag surfaces never seem to be
created that way.
In `gtk4-demos`, drag and drop and popovers seem to be working normally
with this.
Setting variations to their default value causes
them to show up in the serialization of the font
description - a font description has no idea about
the default values, so can't filter them out.
Avoid that.
Try to compute a min size that matches the current aspect ratio.
This means that when interactively resizing, we adapt the min size to
the current window area dynamically.
And that means that we always have a min size that is large enough, but
users can interactively cause it to be small-width x large-height,
large-width x small-width or anything inbetween.
Printing the affected widget leads people to assume that it is to blame
for the error. However, the widget is the object the function is being
called on, not the caller. And the caller is doing it wrong.
Usually the caller is the parent widget, so we could print that one, but
it's only usually, it can be an issue propagating from a grandparent and
it doesn't tell you from where the function is called (allocation or
measuring), so you need a debugger anyway.
So don't put anything there instead.
When the stack is homogeneous in only one direction, the other direction
may produce min sizes to small for all children. Make sure to query at
least the min size for those.
If halign=fill, force adjustment to height-for-width.
If valign=fill, force adjustment to width-for-height.
Otherwise look at request mode.
This way we don't try to adapt the filled dimension and only adjust
the one that is not set to fill.
It's not expensive to check it because we'll cache the dfault size
request anyway, and people do it wrong a lot.
As a bonus, don't do any return_if_fail(), just use the min size
instead.
Ensure that we take the DPI scaling into account so that surfaces will
be placed at their correct positions upon an AeroSnap operation on HiDPI
displays.
Also, use the X coordinate of the surface as-is during snap up so that
we do not inadvertently move the surface to the very left. Also fix the
AeroSnap indicator drawing for snap up so that it is drawn at the
correct places.
Since we are updating these functions, make the old GdkWindow-era
variable names to match better the names we use nowadays.
g_log_writer_standard_streams just puts all the logs
out onto stderr and stdout if we don't stop it. Pango

now showing up, making all the reftests fail.
When the compose file is a symbolic link, take the link itself's
modification time into account (in addition to its target's) in
determining whether to invalidate the compose cache.
This is useful e.g. on NixOS systems where the compose file might point
to a store path with an irrelevant modification time, and we want the
cache to expire when the symlink itself changes.
This grab-induced crossing event may come from outer means while there are
buttons pressed (e.g. WM window drags/resizes in X11), the implicit active
state should be undone in that situation.
Also, separate the handling of GDK_LEAVE_NOTIFY, as it's fundamentally

I forgot to remove the '-Werror=' part from all the extra warnings, so
the warning/error flags we generated were '-Werror=-Werror=warning-flag'

We only want to determine the size pixel-exact, not pango-unit-exact, so
don't spend lots of time wondering if text is half a pixel or a quarter
pixel wider.
Do kep them for debug and debugoptimized builds though.
Keeping -Werror flags in release builds causes issues with forward
compatibility, when new compiler releases or different toolchains
suddenly cause those warnings to be emitted during compilation.
While we certainly want those issues to be investigated and fixed, they
should not prevent anyone from building GTK until they are.

We have a tight coupling with pango, whenever new
pango API appears, our build usually breaks. So

Assume a vbox with 2 wrapping labels saying
Hello World
Hi Ho
being measured for their minimum width for 3 rows of text.
This should be layouted like
Hello
World
Hi Ho
and measured accordingly.
However, previously this was layouted as
Hello World
Hi Ho
with 1.5 lines being assigned to both labels.
That will obviously not compute the above wrapping which clearly
results in a smaller min width.
A reftest testing exactly this was included.
... when they are wrong.
Instead, remove them.
Or in other words: GTK4 does not have a fill child property anymore, so
we don't need to run the measuring loop above to determine the size.
This reverts commit cf7fa931d3.
We store the baseline in the cache and we do not know if baselines might
be queried in the future. So always store them.
No reftest because I don't know how to write one.
premature optimization == √😈
Having a short text and a large max-width-chars should request the
natural width of the text, not the limit from max-width-chars.
This caused huge message dialogs.
Reftests added.
Instead of translating font-variant-caps directly
to OpenType features, translate them to a PangoVariant,
now that that enumeration reflects all the css values.
This allows pango to emulate Small Caps for fonts that

When scrolling embedded widgets out of view,
they sometimes get left behind because we don't
reallocated them. To avoid that, move _all_ children
out of view in size_allocate, and let the current
child allocation plumbing move the visible ones

Non-root widgets should unrealize their ATContext, if they have one,
when they are unrooted, as they don't have a connection to a top level
any more.
Fixes: #4421
Use the debug envvar 'GDK_DEBUG=gl-egl' to determine whether we want to try to
initialize EGL first before trying WGL, as a means for people to more easily
enable EGL support on Windows to test EGL there (such as to debug the shaders,
for instance)
This will clean up the EGL code in GDK-Win32, as well as fixing crashes caused
by using an invalid EGL context in gdk_gl_context_make_current() as we did not
store up the EGL context in the correct place (lost during the transition to
the common EGL initialization code).
On the Windows/libANGLE side, the initialization of EGL has now fully moved to
the common code in GDK, but we will still default on WGL for now. Help is
really appreciated for fixing the shaders on libANGLE!
We need to ensure that gdk_display_get_egl_display() is available even if EGL
is not enabled in the build, so that things will continue to link and work.
For builds without EGL, just return NULL.
This will port the EGL code in GDK-Win32 to use the common GDK code to
initialize EGL. However, at the current state, although EGL is
correctly initialized, this code is disabled for now since
gdk_gl_context_make_current() fails as the shaders do not work for EGL
via libANGLE on Windows.
We can now clean things up in gdkglcontext-win32-egl.c as a result.
Use a label that is long enough to require wrapping and force it into a
hardcoded width. Use a sentence where all the words have the same size
to not get unwanted wrapping behavior.
Also append a 2nd row to check that the first row gets the proper height
allocated.
Found by Marco Melorio.
The width of a logical rect after line breaking is sometimes not
wide enough to cause line breaking to break at the exact same points.
(Is that by design or a bug in Pango? I don't know.)
So don't use the width, and only relyon values we actually set to
pango_layout_set_width().
Don't just use the natural size as the max size, the natural size
is the ideal size, not necessarily the maximum size.
Also check the nat size for opposite min size.
For size -1 in the opposite orientation, GtkBoxLayout used to measure
the children based on their min size in the box's orientation instead of
-1. That wasn't really intended, but was a side effect of how the sizing
code did (not) distribute extra size above the minimum size.
This is clearly not what we want.
What we want is measuring the orientation as is for size -1. Then we
want to just take the maximum of all children and use that.
A reftest is incldued that ensures a vbox wraps a label just like an
hbox does.
The old code couldn't properly do height-for-width because it only
computed the widest and smallest layout instead of looking at the actual
passed in for-size.
The label-sizing reftest has been adapted as the label code is now smart
enough to always display the whole text and no longer requests a too
small width-for-single-row when wrapping.
Ping/pong serials are not meant to be interpreted as user input serials
(e.g. those given back later to the compositor on grabs). As a matter
of fact, Mutter uses a different count (i.e. timestamps) in these, so
using these serials may confuse the compositor into denying certain
operations like DnD.
This reverts commit ba44e7a228.
The change was meant to revert to old GTK3 behavior but it actually
broke new GTK4 behavior that is in use where max-width-chars is used to
determine an ideal size, but where we don't want to limit the width to
that size.
So what happens is the reintroduction of GTK3-style lots of whitepsace
bugs, and we really don't want those.
We also don't want to break backwards compat if we can avoid it.
So let's revert this.
The reftest that was made for this purpose has been adapted.
Fixes#4399
Instead of using GL_BACK, use GL_BACK_LEFT, because the spec demands
this (many drivers don't).
Also move the call from the GDK backends into the GLContext code, as
this is a generic EGL issue (nvidia being the main driver in need of
this call, see 9c4c4eaaa1 for a longer
discussion).

The larger check works well in the headerbar, but not inline in various UI elements. This reverts the larger check since the latter is more common. For selection mode, a separate larger icon (selection-mode-symbolic) has been added to adwaita-icon-theme.

Have square images in the following sizes:
* 20
* 100
* 150
* 200
* 300
and place them in a can-shrink Picture allocated at the sizes:
* 200x100
* 100x200
and set align to center/center.
That's 10 combinations and they should all do the right thing.
This fixes fallout from 3742fabae0 where
we would no longer allocate widgets to their natural size when
align flags where used.
GtkPicture wants to be allocated at 100% in that case, so a picture with
a 100x100 image inside a 200x200 window should be allocated 100x100.
The new adjustment code now does the following (for width-for-height
instead of height-for-width, swap width and height in the following):
1. query the minimum width for the allocated height
2. query the natural width
3. compute the maximum of (1) and (2)
4. set the widget width to the minimum of (3) and the allocated
width.
5. compute the natural height for (4)
6. set the widget height to the minimum of (5) and the allocated height.
But don't call it too early, we only want to call it once we have
prepared the target.
This way, we guarantee that a GL context is always available and that it
is bound to the correct target.
This CSS:
calc(5px+3px)
is wrong because it gets broken to:
calc( 5px +3px )
which is 2 numbers inside the calc, and what you want is:
calc( 5px + 3px )
but you need to add a space to get this, like so:
calc(5px + 3px)
which is the recommended way to write calc() statements.
So whenever we encounter an error, check if the next token is a signed
number and if so, include it in the error message.
This is an alternative to gdk_surface_create_gl_context() when the
context is meant to only draw to textures.
This is useful in the testsuite or in GStreamer or with GLArea,
basically whenever we want to do GL stuff but don't need to actually
draw anything on screen.
A bunch of code will need to be updated to deal with context->surface
being NULL.

This was suggested by Matthias Clasen as an alternative to MR !3929
When adjusting allocations, don't query height for the current width,
but query it for the adjusted width.
And adjust width not to the width-for-any-height, but to
width-for-allocated-height.
Even when we have tons of width available, still do the wrapping at
max-width-chars.
This is what happened in GTK3, too, but it happened automatically
because GTK3 did for_size = MIN (for_size, nat_size) and GTK4 does not.
So we do this manually in the label now.
Fixes the label-sizing.ui reftest.
Ideally this would be using box layout, but it overrides measure() so it's
not possible - so reimplement it instead. Fix an accidentally int division
along the way.
Make it use gdk_memory_texture_from_texture().

detect if an image contains an alpha channel.
This is a port of the fix in the quartz backend to the new macOS backend.
From the original commit:
In macOS-12.sdk CGContextConverSizeToDeviceSpace returns a negative
height and passing that to CGContextScaleCTM in turn causes the cairo
surface to draw outside the window where it can't be seen. Passing the
absolute values of the scale factors fixes the display on macOS 12 without
affecting earlier macOS versions.
Don't pass texture + rect, but instead have
gdk_memory_texture_new_subtexture()
and use it to generate subtextures and pass them.
This has the advantage of downloading the a too large texture only once
instead of N times.
Close widget-factory and observe:
Thread 1:
* acquire main loop
* handle close button
* close window
* dispose video and media stream
* stop GstPlayer
WAIT on pipeline stopping
Thread 2:
* prepare next image in pipeline
* hand image to GtkGstSink
* create GdkTexture from image
* gdk_gl_texture_new() determines format
WAIT on acquiring main loop
Sounds like a deadlock?
Indeed, so don't do that.
It does not belong in GdkGLContext, it's a renderer thing.
It's also the only user of that API.
Introduce gdk_gl_context_check_version() private API to make version

It turns out glReadPixels() cannot convert pixels and you are only
allowed to pass a single value into the function arguments. You need to

Otherwise if we hide and show a window we recreate a new surface,

Make a deep texture, if the render nodes have
high depth content.
For now, we use 32F here for the deep format,
since using 16F causes small rounding errors
that break the memorytexture roundtrip tests.
Look at the framebuffer and the rendernode to
determine what format to use for intermediate
textures.
Our preference here is to use fp16, if we have it
and it makes sense for the framebuffer we're given.
Add private api to find out if the content
of a render node should be considered 'deep'.
The information is collected at creation time,
so there is no tree-walking involved when we
are using this information in the renderer.
Currently, this comes down to whether there are
any texture nodes with high depth textures in the subtree.
In the future, we may want to allow marking gradient
nodes in this way as well.
For MemoryTexture, this is a simple change.
For GLTexture, we need to query the format at texture creation. This
sounds like a bad idea and extra work until one realizes that we'd
need to do that anyway when using the texure the first time - either
when downloading, or when trying to use it in a rendernode, where we
will soon need that information to determine if the texture prefers high
depth.
The term "hdr" is so overloaded, we shouldn't use them anywhere, except
from maybe describing all of this work in blog posts and other marketing
materials.
So do renames:
* hdr => high_depth
* request_hdr => prefers_high_depth
This more accurately describes what is going on.
Also, now make gdk_memory_convert() the only conversion functions
and allow conversions between any 2 formats by going via a float[4].
This could be optimized via fast-paths, but so far it isn't.
If EGL supports:
* no-config contexts
* >8bits pixel formats
* (optionally) floating point pixel formats
Then select such a profile as the HDR format and use it when HDR is
requested.
Forces request_hdr = TRUE for all requests.
Backends should also use this when choosing whether to honor HDR
requests for low quality compositors - as long as the compositor
pretends to support HDR, shovel HDR at it.
Unify the X11 and Wayland EGL contexts.
This is a bit ugly to implement, because I don't want to create an
interface and I can't make them inherit from the same object, because
one needs to inherit from X11GLContext and the other from
WaylandGLContext.
So we have to put the code in GdkGLContext and make sure non-EGL
contexts can't accidentally run it. This is rather easy because we can
just check for priv->egl_context != NULL.
Quietly export this function mainly for the benefit
of libadwaita, which can can use this to install its
implementation of the gtk-inspector-page extension
point.
We have a global GdkGLBackendType now, just set it.
This way, using the variable forces the backend type, and we don't need
special code handling the env vars in the backends.
It also means setting the env var will now "work" on GDK backends that
don't even support that GL backend and simualte another GDK backend
having registered that GL backend already. So you can run
GDK_DEBUG=gl-wgl gtk4-demo
on test what Wayland will do when WGL is in use.
It is necessary to signal the search engine that we are finished and
that we found something for it to reliably show the results. It would
sometimes work anyway since it is sufficient if any backend signals
completion. However if GtkSearchEngineModel was the only backend
returning results then things would break.
The recent change to faster resource generation

hand, we are missing a bunch of links to existing types and symbols.
On Visual Studio-style builds, it is likely that we do not have pkg-config
files for libpng, so improve the search for libpng by using CMake's built-in
mechanisms for looking for libpng. This, however, means that we need to use
'png' rather than 'libpng' for the package name to search for.
Include the appropriate headers as some function prototypes were moved lately.
Also, re-order the include order of the gdk/*private.h headers alphabetically
in the files that were updated.
We don't really need a bus-address property
that gets copied for every single object.
We keep the address in object data on the
display anyway. Just use it from there.
This gets rid of a nice amount of strdups
at startup.
We were only applying <binding> elements when the
object is constructed, which can be triggered by
various things (e.g. a <style> element). Defer
this until we reach </object>, so we can be sure
that we pick up all the bindings.
Testcase included.
Fixes: #4147
The GtkBuilder parser constructs the object e.g.
when handling a <binding> element. There may be
more <property> elements after it, which we were
just not applying. Fix that by always applying
property when we see </object>. To do that, we
need to track the applied status per property.
Test included.
Fixes: #4208
Calling gtk_widget_class_bind_template_child does
*not* give you a reference that you need to unref.
It manages the reference for you. So calling
g_clear_object on such a member is wrong.
Creative people managed to create an X11 display and a Wayland display
at once, thereby getting EGL and GLX involved in a fight to the death
over the ownership of the glFoo() symbolspace.
A way to force such a fight with available tools here is (on Wayland)
running something like:
GTK_INSPECTOR_DISPLAY=:1 GTK_DEBUG=interactive gtk4-demo

We want to group in more than one undo group when removing a selection
and replacing it with a new character or characters, unless we're
replacing a single character. In that case, the natural thing is to treat
it as an atomic change.
We don't want to allow new items to be grouped into a previous action
group after the end_user_action() is called. This ensures that we add a
barrier action in those conditions.
Fixes#4276
On Windows, GLES is not that widely available unless one installs wrapper
libraries such as libANGLE, so GLES/EGL support on Windows is used more like
a fallback mode if Desktop OpenGL (WGL) support is inadequate on the system.
Hence, unless one forces WGL or EGL, we will first try to initialize WGL, and
then try to initialize GLES if enabled and if WGL initialization failed, and
then just return whatever the last result we can obtain from these
initialization attempts, since unlike X11 EGL contexts, we do not have
separate modes for WGL except for legacy and non-legacy contexts.
We were setting the WGL pixel format in GdkWin32Display too early, so the code
does not bail out correctly when we retry establishing the WGL context.
Fix this by pushing back setting the WGL pixel format only after it passes the
shader availability check.
Should fix issue #4257.
When pressing the keyboard arrows to move around when the insertion point is
hidden, it causes an assertion error in blink_cb.
Insertion point blinks should only be scheduled when blinking is enabled and the
insertion point is visible.
Closes#4275
This change removes the assertions limiting replacement strings in the compose table to be less than 20 characters.
The limit seems arbitrary, is not required, will break some users' setups, and problems with it result in applications not launching.
Fixes#4273
The gtk_window_set_buildable_property implementation
was only used to set the unused builder_visible flag.
Remove both the flag and the vfunc.
This means we no longer have any set_buildable_property
implementations and could eventually drop that vfunc and
the support for it in GtkBuilder.
Add a private GdkPaintable implementation that
loads a texture in a thread, and does not show
anything until the texture is loaded. This avoid
blocking on image loading in the main thread.
Silly optimization to get rid of
gtk_main_do_event

created any inspector window in the first place.
gtk_file_chooser_widget_get_choice() is supposed to return the option
id of the choice, but it currently is returning the option label.
Return the option id instead.
When choices are added to the file chooser widget, the options of
that choice are stored object data under the "options" key. However,
gtk_file_chooser_widget_set_choice() was checking for "choices".
Retrieve the options from the "options" key stored data object data.
This reverts commit 87af45403a.
I've found that this change is needed to ensure that the
bounding boxes of text nodes encompass all the glyphd drawing.
Without it, we overdraw the widget boundaries and cut off
glyphs.
We are rendering the glyphs on a larger surface,
and we should avoid introducing unnecessary
rounding errors here. Also, I've found that
we always need to enlarge the surface by one
pixels in each direction to avoid cutting off
the tops of large glyphs.
We can't have other test pop up windows, and possibly
stealing focus and preventing us from getting data
offers. So, run the clipboard test in isolation.
For 2D transforms, we can read the scale
factors more directly off the matrix.
This should eventually be moved out into a
function to decompose a 2D transform into
scale + rotation + skew + translation.
Since we report width and height as integers, the
default implementation of this introduces rounding
errors. This shows up in the node-editor, as having
uneven scale factors like sx=1.0 and sy=1.0035.
Text nodes don't handle uneven scales like that well
and overdraw.
1. Change INSUFFICIENT_MEMORY to TOO_LARGE
GTK crashes on insufficient memory, we don't emit GErrors.
2. Split UNSUPPORTED into UNSUPPORTED_CONTENT and UNSUPPORTED_FORMAT
So we know if you need to find an RPM with a loader or curse and
the weird file.
3. Translate error messages, they are meant for end users.
We were going via GLoadablieIcon/GInputStream for everything previously
and we have no API for that with GdkTexture.
With this commit, gdk-pixbuf isn't used anymore when starting
widget-factory for anything but SVG.
When loading, convert all >8-bit data to
GDK_MEMORY_R16G16B16A16_PREMULTIPLIED.
When saving, save all 8-bit formats as 8-bit RGBA,
and save all >8-bt formats as 16-bit RGBA.
Use our own loader to (de)serialiaze textures
to and from png and tiff.
We still fall back to gdk-pixbuf for handling all
the other image formats, and for pixbufs.
This is a companion to gdk_texture_save_to_png, using
the tiff format, which will let us avoid lossy conversion
of HDR data, since we can store floating point data.
Add support for the tiff format, which is flexible
enough to handle all our memory texture formats
without loss.
As a consequence, we are now linking against libtiff.
Using libpng instead of the lowest-common-denominator
gdk-pixbuf loader. This will allow us to load >8bit data,
and apply gamma and color correction in the future.
For now, this still just provides RGBA8 data.
As a consequence, we are now linking against libpng.
Color values must be divisible by 15 to be convertible into U8 and U16
values with the same result. 0x80 is not one of these values, so switch
it to 0x99.
We avoid an offscreen if we know the child node
can 'handle' the transform. Shadow nodes can if their
child node does - either the child node is a text node
in which case the shortcuts we take for shadow nodes
will work fine with the transform (we just render the
text node offset), or the child is not a text node,
in which case we render the shadow to an offscreen
anyway.
This change makes the label-shadows reftest pass with
the GL renderer, not by fixing the issue but by avoiding
it.
For shadow nodes, we try pretty hard to avoid
rendering shadows, and and we have a shortcut
that just renders text offset, but we can try
harder to do nothing - if the text is offset
by zero, we don't need to draw it at all.
Tests that overdrawing of content inside an opacity node happens before
the opacity is applied.
This is broken in the GL renderer and causes the opacity.ui reftest to
fail.
We need to use an offscreen whenever there is overlapping
children somewhere in the tree below, just checking the
direct child of the opacity node is not enough.
Fixes: #4261
This also switches the rendering code from using gsk_render_node_draw()
to gsk_renderer_render_texture().
Some tests are broken with the GL renderer, so this patch forces the
Cairo renderer until they get fixed.
The test used to test that GtkBox ordered it's children left-to-right in
CSS, no matter the text direction or pack-type.
But there is neither a pack-type anymore nor does GTK4 do that.
So that test has been broken for yers, it just didn't render anything
wrong.
GLES only allows downloading float if the texture matches specific
criteria and I'm too lazy to determine them, so always fall back.
And the custom stride fallback code isn't necessary, because falling
back does exactly that step already.
Basically, I was building some packages on Guix. I figured out that
wayland-protocols was listed among propagated-inputs for gtk+ package
(gtk-3-24). propagated-inputs holds a list of runtime dependencies,
that should be available to any other package that depends on gtk+.
While discussing we clarified that wayland-protocols is not runtime
dependency. So I moved it to native-inputs of gtk+ package, which
means that, this dependency will be available only to gtk+ package and
only at build time. Once moved, building of other applications that
depening on gtk+ started to fail.
Investigation showed that, all .pc (pkg-config) files prepared by gtk+
package, was including:
Requires.private: ... wayland-protocols ...
Since it becomes requirement, other applications was failing with
missing dependency wayland-protocols of dependency gtk+, for instance:
-- Checking for module 'gtk+-3.0'
-- Package 'wayland-protocols', required by 'gdk-3.0', not found
While actually wayland-protocols is not even a build time dependency
of application that depends on gtk+. Advertisement of such
requirement, is a bit misleading, because one does not need it at
runtime, especially applications based on gtk.
Remove the mention of GNU (since that has not been case
for a long time, effectively), state that GTK is hosted
by the GNOME project, and point to GNOME as a place
for donations.
Up until now, as the focus was moved to the inner button, it was not possible for
assistive technologies to determine the correct labels and descriptions
because developers could set them only for the parent widget.
Now, the proper relations are added so the labels should be picked up properly.

This makes sure that the `GListModel` returned by

This happens in the real world when using the inspector to look at a
node recording of a GStreamer video while the video is still playing.
GStreamer will use the GL context in a different thread while we are
busy trying to download it.
A test is included.
Use a GL renderer to upload textures (and then optionally download them
via release() again). This way, we can test that the GL renderer
properly uploads textures to the right formats (not losing information
for HDR for example) and downloads them again.
1. The download via gdk_cairo_draw_from_gl() was broken sometimes
2. We get easy conversion on fallback by chaining up and using
download_texture().
3. One more place where Cairo is no longer necessary.
1. It avoids Cairo, and in particular conversion to Cairo.
2. Keeping a texture allows easy chaining in the vfuncs.
3. Using a texture means releasing will work for HDR formats
too, once we add them.
A private vfunc that downloads a texture as a GdkMemoryTexture in
whatever format the texture deems best.
There are multiple reasons for this:
* GLES cannot download the Cairo format. But it can download some
format and then just delegate to the GdkMemoryTexture implementation.
* All the other download vfuncs (including the ones still coming) can
be implemented via download_texture() and delegation, making the
interface easier.
* We want to implement image loading and saving support. By using
download_texture(), we can save in the actual format of the texture.
* A potential GdkCompressedTexture could be implemented by just
providing this one vfunc as a compress() step.
We need to invalidate the Pango contexts when
font settings change. Use the new helper
gtk_widget_update_pango_context to make it less
likely that we forget to update some things.
The cairo_t that we create to render glyphs for
the glyph cache needs to match the font options
that are supposedly governing how glyphs are
drawn.
Since we allow font options to be different per
widget in gtk, we need to have them at least at
the level of individual render nodes. Adding them
to the lookup key for the glyph cache has the
side effect of solving another problem: We are
not flushing the cache when font options change.
Since font options affect how the glyphs get rendered,
we need to pass the font options down from the gtk level
to where the glyph cache is populated.
Add a new gsk_text_node_new_full api that takes a
cairo_font_options_t in addition to the other parameters.
If the alpha channel is zero, it doesn't matter what the values of the
red, green and blue channels are: the pixel is still fully transparent.
On most architectures, fully transparent pixels end up all-zeroes
(fully transparent black), matching what's in the reference PNG file;
but on mips*el the blend-difference and blend-normal tests get all-ones
(fully transparent white) and a test failure.

This lets people switch back to font rendering that is closer

The GtkComposeTable cache is always in big-endian format and is
byteswapped on load for the more common little-endian CPUs, but
init_builtin_table() in GtkIMContextSimple can't byteswap the built-in
data without copying it, which is undesirable. Pregenerate both big-
and little-endian compose data, and compile the correct flavour into
each build of GTK. This fixes failure of the composetable test when
building for a big-endian architecture such as s390x and (traditional,
big-endian) powerpc.

Dragging will just drag the render node.
Dropping will replace the current contents of the textview with the
dropped node.
Neat side effect: You can drag the node onto itself to do a
deserialize/serialize of the current text.
This is needed as GskRenderNode is its own fundamental type and has its
own GValue infrastructure. And I want to put render nodes into the
clipboard which uses GValues.
It seems these are sent with `xwindow` set to the root window, so this
was failing to find a surface and get the screen from that.
I'm not sure if there's a reason not to get the screen this way
elsewhere in the function, but it seems this should be correct.
This fixes the behavior of `gdk_x11_display_get_monitors()`, which
wasn't correctly changing when monitors were added or removed. For

monitors when one was turned off and on, but updates correctly with this
change applied:

gi.require_version("Gtk", "4.0")

We can use the new binding helpers to make this
a little less bothersome. That way, it will need
tweaks less often (only when new fundamental types
are introduced).
The child of a GtkExpander is owned directly by the expander whenever
the "expanded" flag is unset.
We are adding an additional reference to the child of an expander when
expander is not expanded.
Additionally, if a GtkExpander is disposed while not expanded, we need
to explicitly release the reference on the child widget that we own.
This reference leak was masked in GTK3 by GtkContainer removing each
child from the parent container by recursively calling
gtk_widget_destroy().
This gesture is set on the whole widget surface, since there's
multiple input targets inside an entry (icons, the GtkText itself)
it makes sense to consider the full entry an area handling clicks.
Ensure these events don't propagate further up, and result in other
actions.
The default theme changed from Adwaita to Default and this tripped up
the logic to detect if the tarball builds contain pre-built css files or
not. Fix this by looking at pre-compiled css files in themes/Default/
instead of themes/Adwaita/.

The font sizes demo had the space between the font-size spans,

When we initialize OpenGL, check whether we have OpenGL 2.0 or later; if not,
check whether we have the 'GL_ARB_shader_objects' extension, since we must be
able to support shaders if using OpenGL for GTK.
If we don't support shaders, as some Windows graphics drivers do not support
OpenGL adequately, notably older Intel drivers, reject and destroy the GL
context that we created, and so fallback to the Cairo GSK renderer, so that
things continue to run, albeit with an expected warning message that the GL
context cannot be realized.
Also, when we could not make the created dummy WGL context current during
initialization, make sure that we destroy the dummy WGL context as well.
Fixes issue #4165.
With gtkmm, when using `Application()`, the display is initialized
before we know the application name and therefore, the program class
associated to the display is NULL.
Instead of providing a default value, we set it equal to program name
when NULL. Moreover, we give up on capitalizing the class name to keep
the code super simple. Also, not using a capitalized name is
consistent with `gdk_x11_display_open()`. If someone has a good reason
to use a capitalized name, here is how to do it.
```c
class_hint = XAllocClassHint ();
class_hint->res_name = (char *) g_get_prgname ();
if (display_x11->program_class)
{
class_hint->res_class = (char *) g_strdup (display_x11->program_class);
}
else if (class_hint->res_name && class_hint->res_name[0])
{
class_hint->res_class = (char *) g_strdup (class_hint->res_name);
class_hint->res_class[0] = g_ascii_toupper (class_hint->res_class[0]);
}
XSetClassHint (xdisplay, impl->xid, class_hint);
g_free (class_hint->res_class);
XFree (class_hint);

Let's focus on fixing the OLE2 DnD protocol.
Same thing as the previous popovermenu commit, except for the base popover
because the popovermenu needs special behaviour with e.g. sides arrow so
we need to have the "cycle around" for regular popovers here too.
Currently when moving the focus with (Shift+)Tab, it also traverses the window's
widgets, although it would be expected that the focus stays within the popover,
as it's (almost) like it's a separate window. This would be consistent with
the behaviour of the Up/down arrows, which do cycle around the focus once it
reaches the end.
So this commit makes the popovermenu cycle around focus in any direction, apart
from left/right because they are used to open and close submenus and it wouldn't
make sense anyway to cycle horizontally as there's usually only one widget per
line.
Long time ago, Cairo shadows in both GTK3 and 4 were drawn at a size about
twice their radius. Eventually this was fixed but the shadow extents are
still calculated for the previous size and appear unreasonably large: for
example, 141px for a 50px radius shadow. This can get very noticeable in
places such as invisible window frame which gets included into screenshots.
https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/3419 just divides the
radius by 2 when drawing a shadow with Cairo, do the same when calculating
extents.

Our compose table format is still limited to 16bit

It broke keyboard focusing any widget added through the custom widget
menu feature. So for example if you put e.g. a custom check box widget
in a menu, you won't be able to focus it.
This is because the gizmo is mostly used to custom drawing with e.g.
CSS for small visual elements like scale markers. That's probably why
gizmo's default focus overrides block the focus from going through
the children. So this commit fixes it by overriding those and passing
the focus through the children.
Slide animations cause changes in the size requests due to the
behavior of GtkRevealer. We can avoid those by using cross-fades, which
don't have that problem.
Besides, cross-fades look better anyway.
harfbuzz has all the information we need, so we
can avoid poking directly at freetype apis. Also
drop the caching of color glyph information until
it turns out to be a problem.
Instead of havoing a label for the video frame that clashes with the
background of the video, add a frame around the text styles box and add
a label for them. As a side benefit, it also makes it more obvious that
it is scrollable.
Note: Most of this patch is just reindenting.
Currently we update the :active property on both the previous and
new focus button. That "visually activate" the button and will
emit ::toggled, but if the button is associated with an action,

with the :active property.

Look who changed his mind since commit 8e2ffb3b46 :-)
The "call" scope means that the callback is only used during the
function call itself (here: gtk_widget_class_install_action()).
That's clearly wrong here, as the callback is invoked every time
the action is activated.
Arguably the "notified" scope is a better match here, where the
lack of a GDestroyNotify parameter suggests that the callback may
be used forever (which is the case here).

This way, it can be set in GtkBuilder.
Also make sure to only ever look at the GTypes set in the formats, as
GtkDropTarget cannot deal with mime types.
Now, we just print a whitespace-separated list of GTypes and mime types.
This makes this neat for 2 things:
1. Parsing it (see next commit)
2. Using it in GtkBuilder (see commits after that)
In particular, the common case of supporting a single GType (or mime
type) looks like just printing the GType (or mime type), which in
GtkBuilder looks like
<property name="formats">GdkTexture</property>
Usually the "dnd-finished" signal will be used to unref the GdkDrag. In
those cases, we would lose the object, so that when we do the final
drag_drop_done() afterwards, we wouldn't have a remaining reference.
With the reference guard, this now works.
Since UCKeyTranslate() converts these keys to Space key unexpectedly,
applications can't distinguish these keys by keysyms.
To solve it, this fix translates these keys by the same way with
function keys & keypad keys.
This patch is equivalent to the patch proposed in:
https://bugzilla.gnome.org/show_bug.cgi?id=702841Closes#4117
It is good practice for (floating) window managers to respect explicit
position hints from clients (as long as the window wouldn't end up
off-screen etc.).
Before commit 13d3afa56e, GTK had a flag for setting the PPosition hint,
but now does so unconditionally. However the real intention is to *not*
request a fixed position, so don't do that.
Currently we use layout coordinates and widget height when determining
where a click or drag has happened. If the widget has top padding (which it
does inside a GtkEntry, for example), the area where it's possible to select
text is shifted down, so the part of GtkText above the layout is not counted
as the draggable area and instead the equal area below the widget is counted.
Since GtkText is always single-line, there's no need to do any of that and
we can use widget coordinates. Then the draggable area matches the widget
and the problems goes away.
The dummy Win32 window that we use to capture display change events and
to create dummy WGL contexts was created with CS_OWNDC, so we really do
not need to (and should not) call ReleaseDC() on the HDC that we
obtained from it, so drop these calls.
Since the shaders need to be updated for using with GLES (libANGLE at
least), default to WGL for now. Unfortunately it is not that common for
Windows to have GLES support, in which the easiest way to obtain such
support is via Google's libANGLE.
It turns out that the problem of the WGL window not drawing was due to
the fact that I messed up where I placed SwapBuffers() during the
conversion... doh:|
At the same time, stop storing the HDC in the GdkWin32GLContextWGL, but
instead always create it along the surface we created, so that it is ready
for use for operating with WGL when we are not dealing with "surfaceless"
contexts. If we are dealing with "surfaceless" contexts, just use the
HDC of the dummy window that we created when we created the
Gdk(Win32)Display.
WGL contexts should now be in working order at this point.
This commit attempts to split GdkWin32GLContext into two parts, one for
WGL and the other for EGL (ANGLE), and attempts to simplify things a
bit, by:
* We are already creating a Win32 window to capture display changes,
so we can just use that to act as our dummy window that we use to
find out the pixel format that the system supports for WGL. We also
use it to obtain the dummy legacy WGL context that we will always
require to create our more advanced Core WGL contexts.
* Like what is done in X11, store up the WGL pixel format or the
EGLConfig in our GdkWin32Display.
* Ensure we do not create the dummy WGL context unnecessarily.
In this way, we can successfully create the WGL/EGL contexts, however
there are some issues at this point:
* For WGL, the code successfully initializes and realizes the WGL
Contexts, but for some reason things became invisible. When running
gtk4-demo, this can be verified by seeing the mouse cursor changing
when moved to spots where one can resize the window, although they
were invisible.
* For EGL, the code initializes EGL but could not realize the EGL
context as shaders failed to compile. It seems like the shader issue
is definitely outside the scope of this MR.
nvidia sets the default draw buffer to GL_NONE if EGL contexts are
initially bound to EGL_NO_SURFACE which is exactly what we are doing. So
bind them to GL_BACK when drawing, as they should be.
See https://phabricator.services.mozilla.com/D118743 for a discussion
about EGL_NO_CONTEXT and draw buffers.
This way, one can force using WGL on Windows even if EGL support was
enabled. Also update the help text for gl-egl as it will apply for
Windows, albeit a bit later.
This has the benefit that we can refactor it and make sure we deal with
GdkDisplay::init_gl() not being called at all because
GDK_DEBUG=gl-disable had been specified.
It's not used there, but both backends have independent
immplementationgs for it.
I want to get rid of GdkGLContextX11 and moving code from it is the
first step.
Now that we have the display's context to hook into, we can use it to
construct other GL contexts and don't need a GdkSurface vfunc anymore.
This has the added benefit that backends can have different GdkGLContext
classes on the display and get new GLContexts generated from them, so
we get multiple GL backend support per GDK backend for free.
I originally wanted to make this a vfunc on GdkGLContextClass, but
it turns out all the abckends would just call g_object_new() anyway.
Instead of
Display::make_gl_context_current()
we now have
GLContext::clear_current()
GLContext::make_current()
This fits better with the backends (we can actually implement
clearCurrent on macOS now) and makes it easier to implement different GL
backends for backends (like EGL/GLX on X11).
We also pass a surfaceless boolean to make_current() so the calling code
can decide if a surface needs to be bound or not, because the backends
were all doing whatever, which was very counterproductive.
The code to create and manage a fake egl surface to bind to is
complex and completely untested because everyone seems to support this
extension.
nvidia and Mesa do support it and according to Mesa devs, adding support
in a new driver is rather simple and Mesa drivers gain that feature
automatically, so all future drivers shoould have it.
... or more exactly: Only use paint contexts with
gdk_cairo_draw_from_gl().
Instead of paint contexts being the only contexts who call swapBuffer(),
any context can be used for this, when it's used with
begin_frame()/end_frame().
This removes 2 features:
1. We no longer need a big sharing hierarchy. All contexts are now
shared with gdk_display_get_gl_context().
2. There is no longer a difference between attached and non-attached
contexts. All contexts work the same way.
Do not treat the context as already current when the value
of context::in-frame changes.
This is so we can bind to EGL_NO_SURFACE if context::in-frame == false
and to context::surface if context::in-frame == true.
This allows getting rid of the attached property in future commits.
The vfunc is called to initialize GL and it returns a "base" context
that GDK then uses as the context all others are shared with. So the GL
context share tree now looks like:
+ context from init_gl
- context1
- context2
...
So this is a flat tree now, the complexity is gone.
The only caveat is that backends now need to create a GL context when
initializing GL so some refactoring was needed.
Two new functions have been added:
* gdk_display_prepare_gl()
This is public API and can be used to ensure that GL has been
initialized or if not, retrieve an error to display (or debug-print).
* gdk_display_get_gl_context()
This is a private function to retrieve the base context from
init_gl(). It replaces gdk_surface_get_shared_data_context().
Create it during init and then reuse it for all contexts.
While doing that, also improve error reporting - that's not used yet but
will in later commits.
This is not used yet, but it allows surfaceless GL contexts.
For that purpose, we need to make the display a construct-only property,
so that it can be set when the surface isn't.
This adds a bunch of very picky checks in the constructor so nothing bad
can happen.
... and move some members from the GdkDisplay struct.
We've always wanted to add one to isolate the display from the backends
a bit more, but so far it's never happened.
Now that I'm about to add more data to GdkDisplay, it's a good excuse to
start.
We try EGL first, but are very picky about what we accept.
If that fails, we try to go with GLX instead.
And if that also fails, we try EGL again, but this time accept anything.
The idea here is that EGL is the preferred method going forward, but GLX is
the tried and tested method that we know works. So if we detect issues with
EGL, we want to avoid using it in favor of GLX.
Also add a GDK_DEBUG=gl-egl option to force EGL at all costs and not try
GLX.
That way, we can give a useful error message when things break down for
users.
These error messages could still be improved in places (like looking at
the actual EGL error codes), but that seemed overkill.
Query the EGL_VISUAL_ID from the egl Config and select a config with the
matching Visual.
This is currently broken on Mesa because it does not expose any RGBA
X Visuals in any EGL config, so we always end up with opaque Windows.
https://gitlab.freedesktop.org/mesa/mesa/-/issues/149
This reverts commit c35a6725b9.
This approach doesn't work because if NVIDIA doesn't work for EGL, the
EGL implementation won't be provided by NVIDIA, so checking the vendor
doesn't work.
Instead, use the display's "leader surface" when no surface is required,
because we have it lying around.
Really, we want to use EGL_NO_SURFACE, but if that's not supported...
Instead of going via GdkVisual, doing a preselection and letting the GL
initialization improve it, let the GL initialization pick an X Visual
directly using X Visual code directly.
The code should select the same visuals as before as it tries to apply
the same logic, but it's a rewrite, so I expect I messed something up.
1. We're using EGL most of the time anyway, so if we wanted to cache
things, we'd need to port it there.
2. Our GL handling is massively configurable, so determining when to use
the cache and when not is a challenge.
3. It makes startup nondeterministic and depend on whether a GTK4 app
has previously been started on this display and nobody thinks about
that when debugging.
4. The only benefit of the caching is delaying GL initialization - which
made sense in GTK3 where almost no app used GL but doesn't make sense
in GTK4 where almost every app uses GL.
So unless I find a big benefit to reintroducing it, this cache will be
gone for good.
Avoids having to use private data, though the benefit is somewhat
limited as we still have to put the destructor in the egl code and can't
just put it in gdk_surface_x11_finalize().
We only have one config, because we use the same Visual everywhere.
Store this config in the GdkDisplayX11 struct for easy access.
Also do this on initialize, because if creating the config fails, we
want to switch to GLX instead of failing to do GL at all.
This also simplifies a lot of code as we can share Visual, Colormap, etc
across surfaces.
There's no need to use g_object_set_data() for it.
We can also stop caching it elsewhere because we know the display has
it.
And finally, we can remove the display->have_egl boolean and use
display->egl_display != NULL instead. We initialize the display at
startup, so that variable is the perfect indicator.
We need to initialize GL to select the Visual we are going to use for
all our Windows.
As the Visual needs to be known before we know if we are even gonna use
GL later, we can't avoid initializing it.
Note that this previously happened, too. It was just hidden behind the
GdkScreen initialization.
We don't want to bind ourselves to GTK3 - both because we don't want to
accidentally cause bugs in a different codebase and because we want to
deviate from it.
While doing so, also store visuals as visuals and not as integers.
And only store one Visual because GTK4 only uses one visual.
And then remove the code that is leftover for dealing with the
compatibility Visual for GTK3.
PS: I'm kinda proud of my STRINGIFY_WITHOUT_BRACKETS hack.
The old code was ordering visuals by depth, but considering that these
days we either use the default visual or a 32bit RGBA visual, that
reordering does not have an effect anymore.
In theory, the only effect is that the GLX Visual selection might select
a different replacement Visual when it checks for improved GL Visuals, but
even there I can't come up with a case where that matters, because
again, the visuals are only reordered by depth and we want to keep the
depth.
In any case, make this a separate commit so bisecting can find this
problem if it ever shows up.
Instead of the display telling the screen to tell the visuals to tell
the display to initialize itself, just init the display directly.
What a concept.
That's a sneaky trick so my edit/compile/test cycle goes faster:
I usually use demos for testing so the tools don't have to be linked for
me to start testing.
If the pointer capability is added, pointer swipe and pinch gestures
will be created. However, if the pointer capability is removed, the
gesture objects won't be destroyed.
If the pointer capability is removed and added several times in a row,
for example due to plugging and unplugging physical mouse, this can lead
to leaking the old gesture objects.
In order to prevent that, this change makes the seat destroy swipe and
pinch gestures when the pointer capability is withdrawn.
It's only used during DND to allow use of the root window's cow window
as a DND target, because apparently gnome-shell used to think that was a
great idea to DND to the overview.
Somebody complain to gnome-shell devs about it not being a good idea if
they want it fixed.
Potentially using Wayland is a better idea though.

It's not 2011 anymore, and we shouldn't randomly build one of 10.000
different combinations of X11 backends (I counted the possibilities) but
exactly the one we expect people to use.
Instead, ensure that sassc is made madatory on git builds (because
it is, we don't ship CSS files anymore) and not even looked for in
release builds (because do ship CSS files there).
We don't want people to build Vulkan support when they just want to get
GTK built.
This is in particular true for GTK as a CI subproject or for people
using jhbuild.
Worse, just having Vulkan support compiled in tends to cause crashes
in the Inspector, even if you are not using it.
GTK supports webm playback, which means a backend should always be
compiled.
The ffmpeg backend however is incomplete (no audio) and as such, we
don't want people to end up with it accidentally.
Since we don't want to drag an entire gstreamer build into our ci
on MacOs or msvc, explicitly disable the gstreame media backend there.
Set all settings to their default values, so we
are less dependent on the environment to be set
up just right. In particular, this fixes animations
being disabled when we happen to run in a vm.
Make _gdk_win32_display_get_monitor_scale_factor() less complex, by:
* Drop the preceding underscore.
* Dropping an unused parameter.
* Using a GdkSurface instead of a HWND, as the HWND that we pass into
this function might have been taken from a GdkSurface, which are now
always created with CS_OWNDC. This means if a GdkSurface was passed
in, we ensure that we only acquire the DC from the HWND once, and do
not attempt to call ReleaseDC() on it.
* Store the HDC that we acquire from the GdkSurface's HWND into the
surface, and use that as the HDC we need for our GdkGLContext.
* Drop the gl_hwnd from GdkWin32Display, as that is really should be
stored in the GdkSurface.
* For functions that were updated, name GdkWin32Display variables as
display_win32 and GdkSurface variables as surface, to unify things.
* Stop calling ReleaseDC() on the HDC that we use for OpenGL, since
they were acquired from HWND's created with CS_OWNDC.
Scale factors can be negative, but we were not
looking out for that, triggering an assertion when
trying to create a render target with negative
width of height. Avoid that.

Eliding totally transparent content from the node tree is
not 100% correct, since filters can make things visible, so
we need to at least preserve the bounds. We can do that by
creating a transparent color node.
Apply heuristics to avoid breaking users existing configurations
with the change to not always add the default sequences.
If we find a cache that was generated before 4.4, and the Compose
file does not have an include, and doesn't contain so many sequences
that it is probably a copy of the system one, we take steps to keep
things working, and thell the user about it.
All tables use the compact format now, and we generate
caches in that format too. Bump the cache version to 3
for this.
Replace the python script for generating the builtin table
by a small C program using the same code to generate the data
for the builtin table. This drops the restriction on only
generating a single character in the builtin sequences.
When we find a Compose file, replace the builtin
sequences with the table we found. This matches the
semantics described in Compose(5), and makes it possible
to drop unwanted sequences from the builtin table.
It is slight change of behavior for users with existing
Compose files. To match the previous behavior, you have
to add
include "%L"
to your Compose file, to keep the builtin sequences in
addition to your own.
This lets us naturally replace matching sequences
while parsing. That means that the semantics are now
"last one wins" if the parser sees multiple entries
for the same sequence.
Add a testcase that checks the new replacement semantics.
Keep the list of composetables private to GtkIMContextSimple,
and just have an api that creates new GtkComposeTables, either
from a file or from data.

In many cases, we have an "extra-menu" property that is used to allow
applications to join menus into the native menu for the widget. Previously,
this was done by nesting that menu in a section.
Doing so increases the complexity of the rules for GtkMenuTracker as you
may want different handling from inside of the section vs toplevel
sections.
If instead we synthetically glue the menus together, we have a much more
natural joining of menus as the application developer would expect for
their menu.
This also ports GtkLabel, GtkText, GtkPasswordEntry, and GtkTextView to
use the joined menu helper.
The joined menu helper comes originally from GNOME Builder and has had
extensive use there.

This allows developers to modify the pango context that is used when
rendering text within the text view.
Such access can be useful to alter how rounding occurs with API such as
pango_context_set_round_glyph_positions() and is needed by GtkSourceView
for proper placement of glyphs within the overview map.
We must call gdk_drag_drop_done() when the drag ends,
successfully or not. Without this, we get an unwarranted
emission of ::cancel after a successful drop.
Since only the first call to gdk_drag_drop_done() is taking
effect, it is safe to call as a fallback, after emitting
::dnd-finished. If the application connects to that signal
and calls gdk_drag_drop_done() itself, its call will take
precedence.
This matches what the X11 implementation does.
We are pretty good at batching commands now, and we can easily
produce batches that exceed the maximum number of elements per
draw call that the hw can handle. Query that number, and respect
it when merging batches.
This fixes the rendering of the overview map in GtkSourceView.
Determine the root_x and root_y coordinates of the drag surface by
relying on the coordinates of the surface where the drag is being
carried out, plus the coordinates that we receive from the drag event,
which is in-line with what the X11 backend does.
This will prevent the drag surface from being initially drawn at the
correct position, but jumping towards the top-left corner of the screen
shortly afterwards.
The DnD support will still need some more updates to function correctly
on Windows, but at least this is a small improvement.
Fixes issue #3798.
This gets the basic mechanics of the drop portion of DnD working on the
macOS backend. You can drag, for example, from TextEdit into GNOME
Text Editor when using the macOS backend.
Other content formats are supported, and match what is currently
supported by the clipboard backend as the implementation to read
from the pasteboard is shared.
Currently, we look up the GdkDrag for the new GdkDrop. However,
nothing is stashing the drag away for further lookup. More work is
needed on GdkMacosDrag for that to be doable.
We will want to be able to reuse the pasteboard reading code from
the macOS DnD drop backend. This just removes the pasteboard
bits from the implementation and allows that to be passed in as in
both clipboard and DnD cases we'll have a specific NSPasteboard
to read from.
We don't want to overdraw when dragging a narrow column
around, and we also need the clipping to avoid picking
the wrong column, when a later column button overlaps

Fixes: #4045
The normal way to associate accels with actions is
to attach a shortcut controller to the widget. The shorcut
controller will inject the accel into the action muxer
tree, so that it can get displayed in widgets that activate
the action (say, in menus.
This approach does not works for generated menus, since the
widgets are not in the hands of the app developer, so attaching
shortcut controllers to them is impractical.
Instead, GtkModelButton has an accel property that gets
bound to the accel coming from the action muxer tree (most
likely put there via gtk_application_set_accel_for_action),
and creates a shortcut controller itself.
The change in this commit is to prevent the shortcut controller
from injecting the accel into the action muxer tree in this case.
Otherwise, the accels get 'stuck' and we won't update them if the
global accels are later changed.
This is a hack, and needs a better solution.
We were pretty aggressive about not registering
observers further than necessary, stopping at the
first muxer that provides an action.
But even though action changes further up in the tree
won't be relevant in that case, we need to listen to
accel changes, since they may come from higher up
in the tree (e.g. when using
gtk_application_set_accels_for_action with an action
that is defined on a widget.
So, register all the way to the top, and stop propagating
action changes when we hit a muxer that provides the action.
In some cases (such as when getting a new parent), the
action muxer doesn't know exactly which detailed actions
have changed accels, so we call primary_accel_changed with
just an action name.
Make the menu tracker item handle that case by matching
either against the detailed name or the the action name.
Take the size from -gtk-icon-size.
Note that min-width/height still works, as those properties are handled
by the generic widget sizing machinery in GTK4.
If we are undergoing a surface move, just apply the next_layout anyways,
even if we are not moving a toplevel surface.
Update the way how we obtain the x and y coordinates of a surface, if it

obtained the underlying Win32 HWND, as we did before. But if it is a
popup, use gdk_win32_surface_get_geometry() to obtain the correct x and
y coordinates to place our popup surface.
Also correct how we compute the shadow dimensions, and the final popup
rectangle as we attempt to layout the popup surface, since GDK-Win32
keeps track of the shadow dimensions in system (unscaled) units, not GDK
units.

The swipe gesture forces values in the spin button that are
"impossible" according to the adjustment. This can break things
in creative ways.
Ensure the steps provided are always multiples of the adjustment
step value, and keep the remainder for further interaction.
In the GTK3 days, the spin button was an entry, with buttons on
top, and the swipe gesture affected the input on the entry bits.
Now the spin button is a container, so this gesture in the capture
phase applies to all contained children (incl. buttons).
Attach this gesture to the entry itself, so the buttons are left
outside this business. The gesture is still in the capture phase
in order to prevent text selection/edition/etc to happen.

The releasing of grabs while a button is pressed (e.g. after starting dnd, or
dragging the window, or going to overview with a pressed button, etc...) was
generalized here in https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/1879.
However we shouldn't break all grabs here. In the case of grabbing popups,
compositors will still emit crossing events between client surfaces (e.g.
popping up and selecting a menu item via press-drag-release), breaking all
grabs here means inconsistent client state, that was
https://gitlab.gnome.org/GNOME/gtk/-/issues/2746.
That was fixed in mutter, by essentially making implicit grabs
owner_events=FALSE, however that breaks the mentioned use pattern entirely.
Mutter is changing this behavior back, so GTK should handle these crossing
events.
The grab that we are interested in breaking here is the implicit pointer
one. Popups will be dismissed via other means if the compositor says their
active grab needs breaking. This still leaves dnd/move/resize drags in
one place, while not allowing #2746 to happen with popups.
We already skip them on the edited cell widget, but it's also a problem for

need to be set to initialize GstGL properly.
Due to a bug in GstGL, the GstGLContext can only be set up successfully
if one of the following is true:
* An OpenGL 3.x or later emulator, such as Mesa is used (for WGL)
* The latest GstGL master is being used, at the time of writing (for
WGL)
* GTK, libepoxy and GstGL are all built only with WGL support (for WGL)
* EGL is being used in GTK at runtime
Special thanks to Matthew Waters for the help during the process.
Add support to share the WGL context in GDK with the WGL context in GStreamer,
so that we can also use OpenGL in the gstreamer media backend to playback
videos. For now OpenGL/ES is not supported for this under Windows.
The process of setting this up in Windows is a little bit more involved, as:
* The OpenGL support in GstGL requires a GL 4.1 Core context, but we may just
get the GL version from wglCreateContextAttribsARB() that we pass into the
attributes, which is 3.2 by default. So, try to ask for a 4.1 Core context
first if we are asking for anything less.
* There is only one GstDisplay available for Windows, so we just use
gst_gl_display_new().
* We must explicitly tell libepoxy that we are using wglMakeCurrent() outside
of libepoxy that is being used in GdkGL, otherwise we would end up crashing
as the GL/WGL function pointers would become invalid.
* We must also deactivate temporarily the underlying WGL context that was made
current by gdk_gl_context_make_current() so that when
gst_gl_display_create_context() calls wglShareLists(), we won't get bitten
by error 0xaa (resource busy), as some drivers don't handle this well when
the GL context is current in another thread.
For the last two points we make use of macros defined by the platforms that the
build is done for to help us carry out the necessary tasks as needed.
Thanks to Matthew Waters for the info on integrating GstGL and windowing
toolkits on Windows.
Visual Studio 2013's linker does not suport `/WHOLEARCHIVE:`, so just
explicitly extract the objects from the static libraries that will
form the final GTK DLL.
We want to find focusable children, so we need to look at
the focusable property, not at can-focus. This is a change
from GTK 3, where can-focus was the correct property to
look at.
The intention of the code is to find a focusable ancestor,
so it needs to look at the focusable property, not at
can-focus. This is a change from GTK 3, where can-focus
was the correct property to look at.

Check that we are indeed running inside an Xorg server before enabling
the workaround.
XWayland or other nested X servers deadlock when that workaround is
applied.
Remove a boatload of "or %NULL" from nullable parameters
and return values. gi-docgen generates suitable text from
the annotation that we don't need to duplicate.
This adds a few missing nullable annotations too.
The script assumes that the git program is in the PATH which may not be always
the case, so if git was not found, fallback to the former behavior of making
VCS_TAG an empty string if the profile option was not set to 'devel'.
Also fix the call to the script so that we do indeed call GIT on the source GIT
repo so that we can get the right short SHA1 sum.
Re-organize the code a bit in the process, so that things seem cleaner.
We iterate here from the target widget up the toplevel checking
for the previous and new grab, there's however 2 bugs here:
- The check for is_shadowed was different to the check for was_shadowed
- The loop started with the assumption that the widgets did not hold
a grab, just to change it if the grab widget was found. (or maybe
it's the other way around? it's unclear with the differing checks
for past/present state).
Make these checks consistent, and ensure we start with the right
assumption for the past/present grabbing state, and accounting that
new/old grab widgets may or may not be part of the pick stack.
With gtk_grab_notify_foreach() just taking care of emitting crossing
notifications due to the GTK grab change, rename it to a more apt
gtk_synthesize_grab_crossing().
The _gtk_widget_grab_notify() function just (maybe) did a) reset
controllers and b) hide toplevels. The second part was a testing
remnant introduced in commit 024d832d94, not part of the original
fix.
Do the former more concisely, called from the place where we figure
out whether a widget's ability to receive events changed due to
GTK grabs. It's across those changes that we are interested in
resetting the controllers.
With the gestures being reset both ways, GtkWindowHandle (and
probably other) gestures are now able to reset after a GTK grab
takes input away (e.g. GtkMenuButton). This could be seen as
a sudden jump the next time they'd be dragged with the mouse,
as the gesture would "resume" the previous interaction.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3942
When a new sequence is added to a GtkGesture, its state is looked
in other gestures in the same group, and made to match in this
gesture. This however happened a bit too early, before the
gesture touchpoint was fully set up. As this may result in signal
emission and whatnot, it's a good idea to make it happen with a
fully set up touchpoint.

The CI pipeline does not do a full clone, so we cannot use `git
rev-parse` to get the short SHA checksum for the current commit.
Of course, since nothing's ever easy, we cannot use vcs_tag() with a
custom command, so we need to generate our out `demo_conf.h` header
straight from a script.
Match GtkListBox, so it's possible to use the same styles for them.
Update GtkListView and GtkGridView docs to reflect that, fix a few gtk-doc
formatting leftovers along the way.
Make gsk_ngl_texture_library_pack always return
the position including the padding. And compute
texture coordinates accurately in all cases (we
were fudging the padding for standalone textures.
The indentation of new lines inside documentation blurbs must be smaller
than 4 spaces, otherwise the Markdown parser will consider the line to

Fixes: #3945
When configuring the inspector display, preserve
debug flags that affect which GL variant we pick.
Otherwise, we may end up with a GLX context on the
default display, and an EGL context on the inspector
one. This hopelessly confuses libepoxy, and things
don't go well when that happens.
If we want to add an EGL implementation for the X11 backend, we are
going to need to move the GLX bits into their own class. The first step
is to declare GdkX11GLContext as an abstract type, and then subclass it
into a GdkX11GLContextGLX type, which includes the whole GLX
implementation.
When loading the emoji data we just try to get the data for a language
while there may be territory specializations and emojibase provides
them.
So, split the loading function and try to load the data for the fully
defined language string (i.e. `it-ch`) before loading the generic one
for the language (i.e. `it`) and eventually falling back to the generic
english.
The change in 875a92b95f made labels strip
out underlines earlier, but overlooked that this made
mnemonics not work before the timeout to show them
has passed. That was unintentional. Make mnemonics
work regardless of their visibility, again.
We can't use this flag for any code that may get run
outside the __builtin_cpu_supports() check, and meson
doesn't allow per-file cflags. So we have to split this
code off into its own static library.
Width and height of a GdkMonitor are derived via wl_output which
talks about physical dimensions of a device and compositors usually
implement this as the untransformed values (e.g. weston, wlroots).
Since the GTK client has no way to figure out if a monitor was rotated,
transform the physical dimensions according to the applied wayland
transform to have the physical dimensions match the logical ones.
Mutter flips the physical dimensions itself but doesn't announce the
transform so this shouldn't break anything there.
gcc says: error: iteration 2147483649 invokes undefined behavior

Add some assertions to tell the compiler.
This was comparing the included image-missing icon
with the one in the current icontheme on the test
system. Works fine as long as we don't change
the icons (which we just did). To avoid this, set
the icontheme to hicolor for this test, which does
not have the image-missing icon, so we end up getting
the builtin icon for both ui files.
When a drop causes the event controller to be finalized
(directly or indirectly), we end up segfaulting while
trying to wrap up the drag operation. So, keep a reference
on the GtkDragSource from when the drag begins to when
it is done.
This fixes a crash in gnome-todo when dragging tasks.
Avoid a nested listbox, show the connector,
don't show information we don't have. Also,
disconnect all signal handlers from the display
when the inspector is going away.
Rewrite this in a way that doesn't depend on kernel
header defines at the time the wayland scanner was run.
This was causing the build to break on Centos 8, where
a bunch of fourcc formats are missing.
If the session bus address is unset, GLib will
helpfully try to autolaunch a bus, which will
fail and timeout. If we set an empty address,
it gives up early.
Some GL drivers such as Mesa-D3D12 do not allow one to call SetPixelFormat() on
a given HDC if one pixel format has been already set for it, so first check the
HDC with GetPixelFormat() to see whether a pixel format has already been set
with the HDC, and only attempt to acquire the pixel format if one has not been
set.
This will fix running with GL/NGL on Windows using the Mesa drivers.
When building for homebrew/linuxbrew on Ubuntu 16.04, memfd_create() is
not available and causes the build to fail.
This adds a proper check for the function.
This fixes nautilus crash and perhaps other callers issues.
Nautilus (and sometimes glib) crashes with malformed URI inside of the

Just from reading the code, it seems that we
should unset .csd and .solid-csd at the same
time, since the are mutually exclusive and
we unset them here so realize() can set one
of them again.
The code in gtkwindow.c for dealing with the various
combinations of client-side decorations and client-side
shadows is entirely too complicated.
This commit does not really clean it up, but simplifies
one of the shadow conditions far enough to make some
sense.
With this change, I get the expected decorations in
all the cases I can easily reproduce locally.
Deriving the resize border size from the shadows
carries the risk that we might end up with uneven
resize borders (or none at all, on some sides).
So, justs enforce that we have a big enough shadow
width on all sides.
Previously it was impossible to compose characters on higher levels of
some keyboard layouts as pressing the level selection key would just
exit compose mode.
Examples for affected keyboard layouts include the Latvian
apostrophe-variant "lv(apostrophe)" (latched third level), the extended
German keyboard layout "de(e1)" (latched fifth level) as well as the
multilingual Canadian keyboard layout "ca(multix)" and the German
neo-layout "de(neo)" and its descendants (shifted fifth level).
To reproduce, set a compose key and select the Latvian apostrophe layout.
Notice that you now can input [ by pressing first the ' and then the 8-key.
Then pressing <compose>'8'8 should produce ⟦, but prior to this patch it
did not.
The invisible resize borders have been wider than they
should, for a while. Go back to a size close to what
we have in GTK3.
To summarize: resize borders will be at most 12 pixels
on each size, but never wider than the windows shadow.
The resize corners have 'legs' of 24 pixels where you
still get a corner resize cursor.

Only send selection-changed events when we either
had a non-empty selection before, or have one now.
This should help orca speak the right things, and
not the wrong things.
Related: #3549
Orca relies on these to keep track of the focus location,
ignoring the focused state. With this change, orca can
once again speak text in entries as I type.
We are starting with a pretty empty a11y object tree,
and we want orca to bring more of it into existence
by navigating the tree. But that only happens when we
send it events. Primarily focus events, which come in
from GTK via the platform_change mechanism. So realize
the context when we are sending platform_changes,
otherwise, orca never gets the mesage.
With most context realization happening inside
GtkAtspiContext in response to D-Bus calls, the
code in gtk_widget_realize_at_context that sets
the role is not executed for most accessibles,
causing them to be stuck with the 'filler' role
that makes orca ignore them.
To fix this, split gtk_widget_realize_at_context
into the actual context realization (getting on
the bus) and the setting of widget-specific
properties, and do the latter part when the
widget is rooted.
This makes accerciser report proper roles for
entries and buttons. Orca still has an issue
with getting the hierarchy populated.
Orca ignores events unless the object is inside an object
with role window and states ACTIVE and SHOWING. To arrange
for this, introduce a new ACTIVE platform state, and set it
for windows when they are active.
This gets orca to be a lot more talkative.
Linux 3.4 added support for the MADV_DONTDUMP option to madvise(), which
requests that the covered memory not be included in coredumps. It makes
sense to use this to prevent cases where application crashes could
result in secrets being persisted to disk or included in dumps that are
uploaded to remote servers for analysis. I've avoided making this fatal
since there's a chance this code could be built on systems that have
MADV_DONTDUMP but run on systems that don't.
This cleans up and moves the code to load files
while taking the scale into account. Along the way,
we drop the last uses of GdkPixbufAnimation, and
consolidate the pixbuf using code in one place.
In commit 4a76abffd4, we deferred unsetting focus
and default until after the next draw, overlooking the
case where the focus is set to another widget before we
ever get to the unsetting.

Avoid passing through random key press or release

Not for symbolic icons.
Don't apply `-gtk-icon-filter: opacity(0.5);` to the symbolic icons as

Symbolic icons can be styled using the `color` property.
Also remove the obsolete comment.
The condition we check for to catch X servers going away

Some locations have to be mounted, but their mounts are not user-visible
(e.g. smb-browse). Though this is maybe a bit weird, it is how it works
for years. The problem is that the commit 267ea755, which tries to get the
default location for opening, caused regression as it doesn't expect such
possibility. Before this commit, such locations were opened without any
issue, but nothing happens currently after clicking to "Connect" except of
clearing the "Connect to Server" entry. Let's fallback to the original
location if the mount was not found to fix this regression.

It is also possible to enable F16C instructions on 32-bit Visual Studio builds,
so also check for the compiler's ability to build F16C code on Visual Studio
32-bit instead of just bailing out.
We need to use __cpuid() to check for the presence of F16C instructions on
Visual Studio builds, and call the half_to_float4() or float_to_half4()
implementation accordingly, as the __builtin_cpu...() functions are strictly
for GCC or CLang only.
Also, since __m128i_u is not a standard intrisics type across the board, just
use __m128i on Visual Studio as it is safe to do so there for use for
_mm_loadl_epi64().
Like running on Darwin, we cannot use the alias __attribute__ as __attribute__
is also for GCC and CLang only.
The __builtin_cpu...() intrisics are strictly for GCC/CLang-based compilers, so
don't use them in the checking code on Visual Studio. The test code will still
compile without this change, but will certainly fail if we want it to link.
Propagate the focus-on-click setting to the button
inside, so that setting menubuttons as !focus-on-click
works as expected. This helps for menubuttons in
header bars, where dragging on the button will otherwise
steal focus from the content.
When 9-slicing shadows, omit the center tile when it is
entirely contained in the outline (that is not always
the case, depending on corners and offsets).
gsk_rounded_rect_contains_rect was calling
gsk_rounded_rect_contains_point, which potentially
checks all four corners, for a total of up to 16
corner/point checks. But there is no need to do
more than 4 such checks to answer the question.
Commit 3dbf5038fa tried to defer focus changes
until after rendering is done. But it failed to do so, since
the toplevel ::render handler is still before rendering of
popups that are attached to that toplevel. To do this
properly, we need to do it in the AFTER_PAINT frame clock
phase.
Fixes: #3725
We used to override cursor to use all-scroll while the
content is being scrolled. Unfortunately, there is several
problems with this:
- It is really only expected certain devices, and we don't
have the device information on Wayland
- With the way cursor setting works in GTK4, non-NULL cursors
of the content (eg the text views ibeam) win, making the
scroll cursor not show up
- Under X11, we seem to miss scroll end events and then
the scroll cursor gets stuck
Therefore, just remove this feature.
Opportunistically use the coloring program for
drawing underlines instead of the color program.
This avoids program changes in the middle of
text.
For the Emoji text scrolling benchmark, this reduces
the program changes per frame from > 1000 to around 100.
Use an IFUNC resolver to determine whether we can use
intrinsics for FP16 conversion. This requires the functions
to be no longer inline.
Sadly, it turns out that __builtin_cpu_supports ("f16c")
doesn't compile on the systems where we want it to prevent
us from getting a SIGILL at runtime.
We only have one shader that uses the color2 attribute,
and it doesn't use the uv attribute, so save vertex
memory by putting those in the same space.
This reduce the per vertex space from 32 to 24 bytes.
This reduces the size of our Vertex struct from
48 to 32 bytes. It would be nicer if we could store
the colors in fp16 format in the rendernodes, and
avoid conversion here. But this is still good.
At times (most often when closing subsurfaces that are scheduling
relayouts) the PHASE_PAINT handling gets broken with the following
sequence:
1. Surface receives wl_callback.done for the previous frame.
Surface is thawed.
2. A new update on the surface is scheduled. PHASE_PAINT is
requested directly on the frame clock. priv->pending_phase is
left unset in the surface.
3. Surface gets frozen
4. Frame clock processes the update scheduled at 2. The surface
is frozen, so paint is prevented. PHASE_PAINT is considered
handled.
5. Compositor emits wl_callback.done again. Surface is thawed.
6. At this point the machinery is off
- The surface didn't paint but has pending update regions
- priv->draw_needed is set in the toplevel and other portions
of the widget tree
- So queueing redraws is ineffective at eventually calling
gdk_surface_schedule_update() again on the toplevel surface.
- We don't paint anymore, so this broken state is not flushed
until other subsurface changes manage to schedule the missing
update.
To fix this, always set PHASE_PAINT in priv->pending_phase when
doing gdk_surface_schedule_update(). If the frame clock turns
around before the surface is thawed, it will still be waiting to
be processed the next iteration.

When we don't get stettings from the portal, the current
fallback is 'awful fonts'. There is no need for that. Instead,
set the fallback values to grayscale antialiasing with slight
hinting.
Move the resources of each renderer to its subdirectory.
We've previously done that for the ngl renderer, but it
is better to be consistent and do it for all the renderers.
We need to invalidate the style when font-size changes,
because we propagate this value through the initial
value of the CSS font-size property, and it will not
be recomputed otherwise.
Forgetting to do so was causing the Wayland im context
to leave behind a dead event controller. This was showing
up as a crash when closing the inspector after changing
the im-module property of a GtkText widget. The crash
was delayed until closing the inspector because the
inspector keeps a ref on the event controllers of the
currently shown widget.
Arrange things so that non-child parameters
are always printed before the children. This
greatly helps with readability, which really
suffers when there's hundreds of lines of indented
children between the node start and its parameters.
Update all affected tests.
This is a pet peeve of mine: When we call
g_test_init() before handling --generate,
the random seed spew pollutes the output.
Highly annoying. I've fixes many test binaries
over the years, but more keep popping up.
Instead of rendering the unclipped child to a texture
(and risking blowing the texture size limit, and bad
downscaling), just render the clipped region, and live
with the fact that we can't cache the rendered texture.
This avoid bad artifacts when scrolling long textviews
in rounded clips.

HighContrast -> Default:hc

HighContrastInverse -> Default:hc-dark
Other themes will fall back to Default, as before.

This was breaking muscle memory of people with

such is life.

Rename the included theme to Default, with 4 variants:
light, dark, hc, hc-dark. This replaces Adwaita,
Adwaita:dark, HighContrast and HighContrastInverse.
We still make the themes available under these names,
and we still set up Adwaita-dark and HighContrastInverse
as the dark variants of Adwaita and HighContrast.
The unification of the theme variants under Default
is not quite perfect; it would be nice to merge
the assets/ and assets-hc/ subdirectories and render
all assets from a single svg file.
If we scroll down in a list that's still being filled, we hit the edge and
initiate overshoot, and then the adjustment's upper value increases. This
leads to an unwanted bounce back.
Additionally, if in a similar situation the upper value decreases, the
overscroll glow gets stuck.
Update kinetic scrolling upper and lower value on changes, and immediately
cancel it if dimensions on that side change.

There was confusion here about the handling of the
modelview transform. The modelview transform we are
getting is already set up for rendering the node

an extra scale on top when the texture would otherwise
be too big.
It seems to make assumptions about text positioning that
are not holding with subpixel positioning. I'm not 100%
sure how that leads to exactly the artifacts that are seen
here, but I am just disabling the test until that is fully
understood.
It makes assumptions about text positioning that are
not holding with subpixel positioning. There is no
guarantee that the next word in a multi-word text
starts on an even pixel boundary, as it does when
you break the text into multiple, separately rendered
blocks.
... until all globals have been received.
The dependency tracking introduced in 4e9be39518 only allows to
specify required globals and processes the closures as soon as
the requirements have been met. There are, however, also optional
dependencies - most notably the primary_selection protocol.
Currently we rely on the fact that compositors like Mutter announce
it before `wl_seat`, even though the order is not specified in
the spec.
Process globals closures only after all globals have been announced,
so optional dependencies can be accommodated.

Move some work out of the loop in visit_text_node.
This takes advantage of the fact that the yoffset
of most glyphs is zero, so yphase generally does
not change in a line of text.
Arrange for the contents to be in a single transform
node that is updated as we scroll. This makes the job
of the render node differ a lot easier, since it does
not have to compare to big containers one-by-one.
Allow comparing container nodes to any other
node, by pretending the other node is a single
child container (if it isn't one already).
This fixes a glitch where we redraw the full
entry text when the blinking cursor goes to
opacity 0, since GskSnapshot then optimizes
away first the opacity node, and then the
single-child container.

<span line_height='1.33'>Line height: This is an example of widely spaced text. It was achieved by setting the line-height factor to 1.33. You can set the line-height factor to any value between 0 and 10.
Note that the line height affects the spacing between paragraphs as well as between the wrapped lines inside a paragraph.</span>
Transforms: <span text_transform='uppercase'>straße</span> <span text_transform='capitalize'>up, up and away</span>
