We now always have a "current point" which is either the last point an
operation was made to, or (0, 0) if no drawing operation has
been made yet.
Adding a contour of any kind to the builder will always update the
current point to that contour's end point.
1. Allow specifying the max number of contours
2. Be smarter about creating the paths:
With 10% chance, create a "weird" path like the empty one or only
points or things like that.
Otherwise create a bunch of contours, with 2/3 a standard contour,
with 1/3 a predetermined one.
Instead of the Cairo method and imitating cairo_path_data_t, use the
Skia method and keep points and operations separate.
That way we get a points array that includes the starting point -
because it's always the end point of the previous operation.

The accessibility bus might not be available, and if it isn't the case,
it means something has failed at a level where the user can't do much
about it. There's no need to emit a critical warning.
We depend on GObject, which already depends on GLib; on older versions
of Meson, this ends up trying to depend on the system copy of GLib,
instead of the sub-project copy, in case the version of GLib we have
installed is too old.
To avoid bleeding edge deprecations we use GLIB_VERSION_MIN_REQUIRED and
GLIB_VERSION_MAX_ALLOWED. Since we depend on GLib 2.66, we cannot use
API introduced in 2.67, even when conditionally compiled.
- Reorder declaration blocks for code legibility.
- Don't lighten text color on :hover and :selected for better contrast.

If an active grab gets undone on button press (e.g. closing a menu), we
will receive a button release on the new target even though it didn't handle
the button press, and disable ::active state.
This causes warnings when handling the button release, as it tries to undo
::active state that is not really there.
In order to fix this, check that the pointer focus actually had an implicit
grab at the time of receiving the button release, before trying to unset
the ::active state.
If the accessible object is hidden, we can skip the emission of the
AddAccessible and RemoveAccessible signals on the cache, as those
objects won't be visible in the accessibility tree.
Simplify getting the accessible role when checking if an accessible
implementation should present itself; this avoids going through
GtkAccessible twice to get the same data.
The GtkAtSpiContext is responsible for removing itself from the root,
which will remove itself from the cache. Any code path that leads to the
GtkAtSpiContext instance being collected passes through the
unrealization phase, which will also unregister the context from the
accessibility bus and from the cache.
- use the old Industrial style menuitems to make the design feel purposeful
- adjust corners to have compatible border-radii of child elements
- include sidebars and navigation sidebars to look consistent

Use the set_minimized method of the xdg_toplevel
interface to implement minimization as well as possible.
It is not possible, since there is no corresponding
state that we could use to update our surface state,
but in practice, it works well enough.

Since GTK4, the functions that used the GtkPackType enumeration,
`gtk_box_pack_{start,end}`, were replaced by `gtk_box_{append,prepend}`,
hence this enumeration isn't used anymore by any function within the
GtkBox type, and the child packing properties were also removed for GTK4.
So this commit adapts the documentation accordingly.
For readonly properties, we show the serialized value
in a label. If we don't take precautions, this can cause
our window to grow extremely wide, and break things.
So, ellipsize things at a reasonable size.
Fixes: #3278
GtkTreeView.get_tooltip_context() takes an inout X and Y coordinates,
but the "out" side is a side effect: the conversion from widget-relative
to bin window-relative coordinates is not documented, and can be done
using public API, if needed.
GtkIconView.get_tooltip_context() follows the same pattern, and takes
two inout arguments for the coordinates, but it does not change them any
more, after GtkIconView's bin window was dropped in commit 8dc5e13e.
There's really no point in having these `inout` arguments, and while
GtkTreeView and GtkIconView are certainly de-emphasised in GTK4, and we
nudge developers to move to the new list views, we should take advantage
of the API break to remove warts.
This commit fix the warning:

Using GtkCssSection in public headers here may be
ok from the C perspective, since it all ends up in
the same library anyway. But it causes circular
dependency problems for our gir files that are still
split by namespace.
To avoid this problem, copy the GtkCssLocation struct
struct as GskParseLocation, and pass take two of them
instead of a GtkCssSection in the error callback.
Update all users.

In commit 024d832d94, we introduced a
cascade-popdown property that makes closing a submenu
propagate up and close its parent menus. This is the
behavior we want when a menuitem in the submen is
activated.
What we overlooked is that we still need to be able to
close a submenu during navigation, before opening another
one. And in this case, propagating the closing is breaking
things. Fix this by adding a private close_submenu api
to GtkPopoverMenu that avoids the propagation.
Fixes: #3301
When falling back to using the program name to create a unique base path
for the objects on the accessibility bus we need to ensure that the name
is a valid DBus object path.
glFrameBufferTexture maps to all faces of a cube and that is not needed
here. Additionally, texture_id is not deleted after we use the additional
flipped texture, but should be.
The AT-SPI cache interface is used to quickly populate the accessible
objects tree.
The tricky bit is ensuring that we emit change notifications on the
cache only when the cache is available, which means waiting until the
root is asynchronously registered.
The root path is shared by all AtSpiContext instances, so we should
compute it once, instead of every time we instantiate a new context.
This allows us to defer the path creation at realization time and ensure
that we have a registered application.
The expected behavior when activating check or radio
menuitems via keynav is that Space toggles the item
but keeps the menu open, while Return toggles the
item and closes the menu.
Ever since 5b5d2665d3, tooltips don't work properly,
since we get more motion events now, and those keep the
tooltips from appearing. This can be seen e.g. on the icon
in the password entry in widget-factory, or on the section
switcher buttons in the Emoji chooser.
Ignore synthetic motion events for the purposes of
determining whether the user moved the mouse.
Currently GTK can be built with G_ENABLE_DEBUG which enables various debug code and parsing
of those env vars, or without, which instead of parsing them prints a warning if they are set.
While building with G_ENABLE_DEBUG isn't strictly needed it's the only way to make GTK_DEBUG=interactive work,
which is a nice thing to have always.
This enables parsing of those env vars in any case and allows specific values being marked as also
available when not built with G_ENABLE_DEBUG (interactive for example). If not built with G_ENABLE_DEBUG
then all unavailable values will be marked as such in the help output and a note is added that
GTK needs to be built with G_ENABLE_DEBUG to use them, which should help discoverability.
An implicit grab means some button is down, reset the active state
only in that case when we get a grab broken event.
Avoids active state accounting warnings when we do get active grabs
broken (e.g. after selecting a menu option).
Since the $button_fill variables are no longer used outside of the
button() mixin (and it was for an ugly hack), there is no need to keep
that anymore.
Fixes https://gitlab.gnome.org/GNOME/gtk/-/issues/3354
We may have the situation of multiple touchpoints in the same
widget, or combinations with other devices. Stack those ::active
states are preserved on widgets on all but the last pointer/touch
going away.
Use the GROUP role, and make sure to note that the child is always
revealed. Unlike GtkExpander, GtkRevealer can only be programmatically
toggled, so we cannot turn it into a "button" object.
Document the role of the GtkTreeExpander, and the behaviour of the
expander button.
Additionally, improve the label of the expander button, by adding a
fixed "Expand" label, and setting the "labelled-by" relation to the
child of the GtkTreeExpander.
The search bar widget has a "SEARCH" landmark role, which is described
as:
A landmark region that contains a collection of items and
objects that, as a whole, combine to create a search facility.
Commit fa3d1940bf added separate grab handling for GtkSearchEntry, but
didn't consider whether the bar was revealed or concealed. The expected
behavior for the latter is that the entry is cleared rather than focused,
fix the condition accordingly.
With the last commit, pressing the same button with multiple fingers
doesn't cause extra emissions, so we can remove exclusive and allow
pressing multiple buttons at once on touch.
Add a possible replacement for GtkEntryCompletion
as a demo.
Move the Dropdowns demo to Lists/Selections, and make
it show both GtkDropDown and the suggestion entry, with
some variations.
Now that GtkATContext is explicitly realized and unrealized, we should
always create an instance at widget initialization time, and drop it
during the widget finalization. This should make it easier to set up the
initial accessible state of a widget during the instance initialization,
as well as reduce the chances of accidental creation of GtkATContext
instances during the destruction sequence.
Since GtkATContexts are now lazily realized, we need to go through the
GtkAccessible's implementation to access the :accessible-role property,
in case there are fallbacks.
There's no need to do a lot of work on construction, if we're delaying
all remote work after the GtkATContext is realized.
The GtkAtSpiContext should also keep a reference on the root, and drop
it at unrealize time.
By unrealizing the context we avoid additional work during the dispose
phase, in case widget code updates the accessible state. We use
GtkAccessible's API, to ensure we unrealize the right ATContext, instead
of the one we store inside GtkWidgetPrivate.
We drop the ATContext instance inside GtkWidget during finalization, to
mop up eventual vivifications there.
Making the list row child css depend on the position
is very expensive, and does not acutally work correctly
(since we don't have widgets for all children, so the
position of the child widget does not reflect the actual
model item position).
To make this more palatable, use the bottom border
instead of the top border, since most lists have a natural
border at the top (with headers), and may end up with
empty space at the bottom.
The overarching goal here is to not queue a resize
unless something has actually changed. In columnview
scenarios, we often deal with hundreds of labels.
Labels are cattle, not pets.
This is leftover code from when widgets were hidden
by default, and was setting them back to their initial
state.
This is getting in the way now, as hiding the widget
updates the HIDDEN accessible state, which ends up
re-creating the at context that we've already disposed
of, leading to memory leaks.
For builds that do not have PangoFT2, the demo fails to link because we weren't
building listview_ucd.c. Fix the build by building listview_ucd.c with
script-names.c and unicode-names.c for all builds, as we now require a Pango
version that already always depends on HarfBuzz and those sources do not use
anything from PangoFT2.
gtk-builder-tool simplify --3to4 now produces a
<requires lib="gtk" version="4.0"/>.
Adapt for that, and also add some tests that check that we
actually verify the requires, and accept 3.99 and 4.0, but
not 5.x.
The hypothetical widget that needs to clone ATContext instances
because it needs to control the accessible role post-construction is
really GtkModelButton.
Fixes: #3342
Some widgets might want to override GtkAccessible and create their own
context in order to control the accessible role post-construction time.
To avoid explicitly copying the existing state over from the original
ATContext to the new one, we need a way to clone the context's state
from inside the ATContext itself.
Using GList is a bit lame, and makes the API more complicated to use
than necessary in the common case.
The only real use case for a GList is gtk_widget_add_mnemonic_label(),
and for that we can use the GValue-based API instead.
Fixes: #3343
The accessible-role property in GtkWidget has three possible targets:
- the :accessible-role of a GtkATContext, if realized
- the accessible_role field of GtkWidgetPrivate
- the accessible_role field of GtkWidgetClassPrivate
When we set the accessible role of a widget using the GObject property
mechanism, we want to either set the GtkWidgetPrivate.accessible_role
field, if there's no ATContext *or* if the ATContext is not realized.
Conversely, when we get the accessible-role property we want to have a
series of fallbacks in place:
- if GtkAccessible.get_at_context() returns an ATContext, and that
ATContext is realized, return the :accessible-role of the context
- if GtkWidgetPrivate.accessible_role is not WIDGET, return the
stored accessible role
- return GtkWidgetClassPrivate.accessible_role
This should help catch the case of getting the accessible role of
widgets that override GtkAccessible.get_at_context(), like
GtkModelButton.
See: #3342
Use a single environment variable for everything:
- select the ATContext implementation
- select the test ATContext
- disable ATContext entirely
We use the same pattern as GSK_RENDERER, GTK_DEBUG, etc.
The documentation needs to be updated to include the environment
variable.
The GtkPlacesOpenFlags enum is only used in private
API, so move it to private headers. Since we still need
a GType for it, add gtkplacessidebarprivate.h to the
headers we use for generating private enum types. In turn,
this registers the other private enums in that header, so
take the opportunity to fix their naming, and use the
generated types for the corresponding sidebarrow properties.

On desktop GL, GL 1.5 or GL_ARB_occlusion_query is required to get the
glGenQueries() etc. symbols. This isn’t the case on GLES, where they
are provided by GL_EXT_occlusion_query_boolean, and more importantly
have never been made core.
This patch allows gtk4-demo to start when GDK_DEBUG=gl-gles is set, on
my Mali 400 MP running the Lima driver from Mesa.
Check the text handle role, instead of looking for the other handle
visibility. The other handle may be invisible during selection mode
(e.g. pointing to offscreen contents). This fixes both this code
switching to cursor mode out of the blue, and possible crashes later
on as this handle might be hidden in the process, while its own event
controller is handling events on the parent surface.
The gtk_text_view_set_handle_position() function called some lines above
takes care of handle visibility already, also accounting for other
conditions (e.g. whether the handle points to contents onscreen).
Forcibly showing handles here misbehaves if the handle should stay hidden,
and somewhat expensively as it involves creating and throwing a native
surface every time.
With the scrolledwindow drag gesture not claiming the sequence immediately,
we end up placing the cursor (and undoing the previous selection) each time
we scroll.
There is already handling too short drags in ::drag-end, so let this code
handle touchscreens as well.
If the gesture becomes captured (e.g. from a parent scrolledwindow), we
leave some things in the air. Clean these up properly. This is recurrent
with touch scroll.
In destruction paths of a focused entry, the IM context might first
end up detached from its widget, then destroyed. This currently prevents
the IM context from detaching itself from the GtkIMContextWaylandGlobal.
Make it do so when unsetting the client widget, so the IM context gets
properly unfocused before destruction.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3176
In wayland, popup positioning and event handling are doubly async.
This makes it unreliable to figure out parent surface coordinates
out of the popup position and the events received. This results in
jumpy text handles there.
The best way to deal with parent surface coordinates is to handle
the events there. Make the handles transparent to input, and make
the drag gesture be set up on the parent widget's native.
The gesture is set up in the capture phase, setting it on the native
(as opposed to the parent widget) achieves a feeling similar to it
being a distinct surface, as it should take precedence over other
gestures in the emission chain (e.g. scrolledwindows).
As everything is in parent widget's native's coordinates, the drag
handles become smooth again.
The intended use case of the "presentation" role is
| […] when an element is used to change the look of the page but does not
| have all the functional, interactive, or structural relevance implied
| by the element type, or may be used to provide for an accessible
| fallback in older browsers that do not support WAI-ARIA.
One of the examples is, literally:
| An element whose content is completely presentational (like a spacer
| image, decorative graphic, or clearing element);
Which fits perfectly for the GtkTreeExpander's "indent" builtin icon
widget.
Mark gtk_drag_icon_create_widget_for_value with
GDK_AVAILABLE_IN_ALL, since it is meant to be public.
Also, clarify the documentation a bit.

Once we figure out what is going on with textures, changes are we'll be
able to let this stay a zero rect. But that is still a bit up in the air right now.
When we close grabbing popups due to an outside
click, check at each level if the click is still
outside. This makes closing the nested popover
menu in the popover on page 3 of widget-factory
work as expected, when you click the menubutton
again.
When an event happens on a non-grabbing popup that hangs off
a grabbing popup, don't trigger the autohide. This makes touch
text handles work inside the popover on page 3 of widget-factory.
We are doing too much work during the construction phase of the
AT-SPI backend for GtkATContext. Instead of having the AtSpiContext
register itself at construction time, let's add explicit realize
and unrealize operations, and connect the ATContext realization to the
rooting operation of a GtkWidget.
We can just call gdk_surface_invalidate_rect here
like we do elsewhere in gdk, and I'm a bit uncertain
about the current code that adds an empty update
region.
We don't want the popover to stay open when we open
an about dialog or shortcuts window. Since cascade-popdown
would also affect e.g. the context menu of the text widgets,
do this explicitly.
The magnifier in entries is magnifying the GtkText
widget, which does not draw any background itself.
Therefore, we give the magnifier a background, to
make things look as expected.

Install a log writer function that is a bit simpler than
the default GLib log writer, and does not put PIDs and
timestamps in the output, so we can compare easily in
our testsuite.
It doesn't make much sense to set this in per-directory
meson files, since that makes use use different logging
facilities in different parts of the project. Set it
globally.
We are setting the value to TRUE initially, but
the property had a declared default of FALSE.
This is messing up the simplification of .ui files
with gtk4-builder-tool, since it thinks it can
omit can-target properties when it really can't.
We were not checking the passed-in type in the right
way. An interface type can still pass the
g_type_is_a (..., G_TYPE_OBJECT) check, if G_TYPE_OBJECT
is one of its prerequisites. What we need to check is
whether the fundamental type is G_TYPE_OBJECT.
The tests in subdirectories of testsuite/css were
using an environment defined in the parent directory,
causing them to not find their test data. Give each
test directory its own environment.
When using GtkBuilder to create constraints and guides,
the layout manager is already rooted when the guides get
created, and we were forgetting to create the guides
constraints in this case. Fix it by adding a call to
gtk_constraint_guide_update().
This was showing up in the new builder-based constraints
demo as the guide not having the expected effect.
This isn't strictly required for correctness, but
it makes the GtkBuilder codepath do the same that
the vfl codepath does: call gtk_layout_manager_layout_changed
only once, after all the constraints have been added.
The Cairo implementation for the Macos backend uses a toplevel
window with full transparency and a series of NSView to create opaque
regions. This improves compositor performance because it allows the
display server to avoid costly blends.
However, we want to ensure we clip better when exposing the
transparent region so that we only expose the shadows/corners as
necessary.
This typedef was not used in any public APIs, and is
only used in the MacOS backend. It is not worth preserving
as public API, move it to the only user.
This implements the basics for a GdkGLContext on macOS. Currently, rendering
only is fully working for the GskCairoRenderer case where we read back pixels
into a cairo surface for rendering. More work on synchronization is required for
the GL on GskGLRenderer case.
When we attempt to render a surface itself with GL, the context will ensure that
the new GdkMacosGLView is placed within the NSWindow. In other cases, we
use a dummy NSView and NSWindow for backing the NSOpenGLContext to
ensure that we can get accelerated drawing.
This gets GtkGLArea working when running with GSK_RENDERER=cairo.
This helps a situation where the window contents has not changed
in time for a drawing. Setting the texture gravity helps that side or
corner to be less jittery while moving.
Ideally, we can get to a point where we are synchronized and keeping
up with drawing fast enough to not need this. That may require some
work to drive frame clocks from drawRect: though.
This follows the mockups that these demos are
copied from. Unfortunately, it has to be implemented
for every item factory, so we repeat it here.

This makes it so that you have to explicitly specify
"true" and "false" for the checked state, but it
matches how this enumeration is meant to be used.
It turns out gtk-doc can't even parse its own custom
links if you don't arrange for the <link> element to
on a single line, since it is just a glorified sed
script :(
This ensures that keybindings for small-step changes
work despite draw-value being FALSE now. This was
fallout from 8ca612c966 that showed up
as arrow keys not working anymore for the color scales
in the color chooser.
Instead of monitoring the list of toplevels, rely
on GtkWindow updating the HIDDEN state before windows
get removed. This is better, since we still have the
object available when it happens, so we can pass it
to the ATs.
We want to use the HIDDEN state to control when
things get added and removed from the accessible
tree, so ensure that we a) set HIDDEN to true
initially for windows, and b) we update HIDDEN
when a window is shown or hidden.
The second part is handled by gtk_widget_hide
for other widgets, but hiding a window does not
always go through that code path.
When a toplevel window gets hidden (and not destroyed),
the frontend code set the HIDDEN state, and we need to
emit child notification when that happens.
We need to use gtk_accessible_should_present() whenever we
calculate accessible tree positions, to avoid inconsistencies.
While we are at it, make these helpers usable for finding
the position of accesibles that are now ignored, by not
looking at should_present for the object itself. This will
be relevant when we calculate the position of objects whose
HIDDEN state changes.
We need to translate the list model position into
an accessible tree position, since hidden toplevels
will be skipped.
While we are at it, add an api for this notification
that will be used in the next commit.
Hidden elements are not presented in the accessible
tree, so when then HIDDEN state changes, we should
emit child-added or -removed signals.
This commit does not yet handle all cases (HIDDEN
toplevels or hidden stack pages are not handled),
but it should cover the common case.
The ARIA spec is clear on this: when an element has the
HIDDEN state, it should not be presented in the accessible
tree.
This change is incomplete, we also need to emit child-added/
removed signals when the state changes, but that needs to
wait for the child added infrastructure to land.
gtk_widget_reposition_after is called both to add new children,
and to reposition existing children. We only want to emit
accessible changes in the former case (since AT-SPI doesn't
have events for reordering).
The current code was marking queued events as flushed,
but left them in the queue. That doesn't make sense to
me - we should deliver all events we have before we
reach the paint phase of the frame cycle.
Unparenting the stack finalizes the entry and label,
but at least the label is available via the
gtk_editable_get_delegate API, and the a11y
implementation uses that at dispose time. So, clear
the pointers to prevent them from being dangling.
This was showing up as a segfault of the doc-shooter.
When the compositor unmaximized the window, we get a
state-changed signal, and we update the maximized field.
But then we go and recompute our layout based on the
maximize_initially field, and that is still TRUE, when
we were maximized initially. So we need to update both
fields.
This fixes a problem where using the window menu to
unmaximize an initially maximized window would not
work.
Fixes: #3226
These tests are a bit fragile because the initial focus
that is taken depends on what ends up in the center of
the window, horizontally or vertically, which depends
on things like fonts, or theme spacing.
This commit makes some tweaks to push things in the
widget-factory example around far enough to make the
tests work again.
We should figure out a way to make this more robust.
We are not using a box layout here since we want
to ignore the icons for measuring. But we still
want the layout to respect border spacing that
comes from the theme.
If the operation mode is OPERATION_MODE_RECENT and we end up in the
'goto file_entry' case, we don't set info.result. Then later after
calling check_save_entry, is_empty is TRUE which causes a goto out and
here we then try to use info.result, which is uninitialized.
Initialize info.result before doing all this.

Unparent the child widget before tearing down its
stack page. This is necessary so a11y can still access
the stack page accessible to emit change notification
when it learns that the child is removed.
Since we mention abstract roles in the documentation
for GtkAccessibleRole, we should say what roles are
abstract. Doing this shows that we actually use two
abstract roles heavily, ourselves: WIDGET and WINDOW.
GtkModelButton is no longer derived from GtkButton,
but can still treat it like a button for the purposes
of having a click action. This lets ATs activate
menu items again.
When the button role changes, we want to update the
accessible role to match. Since accessible roles are
unchangeable post-creation of the AT context, we have
to cheat a bit and recreate the whole context.
Set the accessible role to GTK_ACCESSIBLE_ROLE_MENU_ITEM.
This is incomplete, we need to recreate the context when
the buttons role changes, and there are other things that
need to be set.
Some people read the "Getting Started" section as a series of
incremental lessons, and having the examples go from GtkApplication to
the old style "init / spin the main loop" confuses them.
We should be using GtkApplication everywhere in our examples.
According to section 7.1 of WAI-ARIA, the progressbar role

According to section 7.1 of WAI-ARIA, the slider role

Recompute the layout when the css style change
affects text attributes. This matches what we do
in GtkLabel, and without this, changing the
font-features-setting css property in the Inspector
does not have immediate effect.
The last event, matching lifting the finger/releasing the mouse button,
is important when there's a large delay between it and the previous events,
as in when performing a movement, stopping, then releasing fingers as
opposed to doing a swipe.
If this event is skipped, doing this will result in kinetic deceleration
matching the previous finger movement, while the expected behavior would
be no deceleration.
See also 5dc6194b98 for a similar fix in
GtkEventControllerScroll.
GtkAtSpiRoot is not a context, which means it needs to emit
ChildrenChanged events by itself whenever a toplevel is added to, or
removed from, the list of toplevels.
A bit hacky: we skip parsing values that have a reference or
reference-list type, but we do not error out. Instead, we return a NULL
value, which we catch in the GtkBuildable interface implementation to
get the actual object, and construct a reference list value.
There's still some ickyness around the value type that can only be
solved by having an attribute and role taxonomy.
Accessible attributes are not GObject properties. This means that we
need a custom parser for setting attributes in our UI description files.
The new section is defined as a sub-tree with the `<accessibility>`
element at its root, and elements for each type of accessible
attributes, i.e. properties, relations, and states:
```xml
<object class="..." id="...">
<accessibility>
<property name="label">The accessible label</property>
<state name="pressed">false</state>
<relation name="labelled-by">label1</relation>
</accessibility>
</object>
```
The name of the attribute is the enumeration value; the value is defined
by the WAI-ARIA specification.
The nameless, faceless gizmos inside a range do not
contribute to the accessible experience at all, lets
not add them to the tree. All the accessible functionality
is on the main widget (either a scale or a scrollbar).
Show the object path of the object on the a11y bus,
this is can be useful information. While we are here,
make sure that the Inspector does not throw criticals
when used with GTK_NO_A11Y=1.
There were several places where we were confusing
GList and GSList and list->data and list->next, causing
a crash in the accessible name computation for buttons
with mnemonic labels.
Anybody who keeps their own CSS nodes around or wants to order CSS nodes
different from widgets will from now on have to do it manually all the
time.
This is outdated behavior, nobody should be doing either of those two
things.
Also, the correct case is much more common, and not doing it
automatically was causing bugs.
Fixes#3280
The stack page objects were not properly integrated
in the accessible tree - they were appearing as parent
of the pages when navigating up, but not as children
of the stack when navigating down.
Instead of falling back to the role nick for both,
fall back to the class name for the name, and to
the empty string for the description. This makes
labels show up in Accerciser the same way they
did in GTK 3, and seems more useful to me than
the alternative.
Set the expected accessible role on the tagged entry
widget in the demo of the same name. Accessible tools
may decide to ignore widgets that have the wrong role,
so setting an appropriate role is important.
The ARIA spec determines the name and description of accessible elements
in a more complex way that simply mapping to a single property; instead,
it will chain up multiple definitions (if it finds them). For instance,
let's assume we have a button that saves a file selected from a file
selection widget; the widgets have the following attributes:
- the file selection widget has a "label" attribute set to the
selected file, e.g. "Final paper.pdf"
- the "download" button has a "label" attribute set to the
"Download" string
- the "download" button has a "labelled-by" attribute set to
reference the file selection widget
The ARIA spec says that the accessible name of the "Download" button
should be computed as "Download Final paper.pdf".
The algorithm defined in section 4.3 of the WAI-ARIA specification
applies to both accessible names (using the "label" and "labelled-by"
attributes), and to accessible descriptions (using the "description" and
"described-by" attributes).
Our Text implementation requires that we have
a GtkEditable with a delegate that is a GtkText
widget.
This change make the Text implementation work for
the custom widget in the tagged entry demo.
Implement the non-questionable parts of the Component interface
for accessibles which are widgets.

Make right-aligned content work in resized columns.
There is currently no way to make a title right-aligned,
but we can still make it work correctly. This is a follow
up to 7eb0ae39c5.
Fixes: #3276
When resizing columns, we clip a shrunk column
on the right, so the separator disappears in that
case unless we put it on the left side of the other
column.
GLDEBUGPROC callback is defined with APIENTRY which is a windows
specific calling convention. That macro expands to nothing when building
on other platforms.
Fixes: #3268.
Ensure that the column resize cursor stays in place
for the duration of the resize drag. This is a bit
annoying, since the implicit grab can end up on the
header of a different column from the one we are
resizing, so just set the cursor on all column headers.
Make it so that for overlapping resize rectangles (with
very narrow columns), we prefer the narrow column, so you
can regrow a column after shrinking it all the way.
Related: #3274
Ensure that we place the resize rectangle at the visible
right edge of the column, not where the allocation ends
(we clip the header drawing, after all).

This gracefully disable ffmpeg, gstreamer, cups and cloudprint optional
dependencies when they are not available, while still giving full

It is nicer for contributors to have a build that works by default.
Distributors should be using -Dauto_features=enabled to get ride of
automagic options.
There is no reason to fallback to find_library for cairo and still rely
on pkg-config for all other dependencies, and just when using MSVC. When
building and pkg-config is not working it is preferable to fallback to a
subproject just like for all other dependencies.
Also add cairo.wrap now that meson support has been merged upstream.
Call SetCapture() explcitly for the (new) modal window so that we make the
modal window respond to mouse input, and also call SetCapture() to the parent
of the transient window that we are destroying so that mouse input capture is
returned to the parent window.
This attempts to fix the following:
* Upon creating a new modal window, the new modal window does not receive
pointer input unless one switches to another program and back
* Upon closing a transient window, the parent window that activated the
transient window does not receive pointer input unless one switches to
another and back
This reverts commit fc2008f2.
Turns out, we *don't* have code to maintain Z-order. Restacking
code is not doint that, it just enforces a few weird Z-order-related
behaviours.
Make sure that we get the state of the modal window properly, and send out the
corresponding notification signals.
This will ensure that we do not try to activate windows that should have become
inactivated due to it opening modal windows and render the program unresponsive
because we are not activating the correct window that is due to receive user
input.
We only want to show relevant, local actions for
widgets, but _gtk_widget_get_action_muxer() will
return the muxer of a parent widget (all the way
up to the toplevel), if the widget does not have
any actions of its own. To detect this situation,
compare what _gtk_widget_get_action_muxer() returns
for the parent widget, and act accordingly.
The buttons here are not really buttons (the action
is not tied to the "clicked" signal), so triggering
the buttons via a11y does not have the expected effect.
And we expose the Value interface that ATs can use
to set the value.
The nested window was not modal, causing it to be
inoperable. And the nested views within were all
shrunk down to nothingness. Give them some width.

The Selection interface is defined in terms of child
positions, so we need to always translate from that
to model positions if we want to use the selection
model apis.
Add a paragraph to the migration guide that explains
how to properly render symbolic GtkIconPaintables.
Also mention this in the GtkIconPaintable docs.
There's a reason you can't spell 'paintable' without
'pain'...
Using GtkIconPaintable+GtkPicture is not good for symbolic
icons - they don't get properly colored that way. So change
things around to use the icon name if we have it.
Fixes: #3252
The 'has_uncommitted_ack_configure' state was added to make sure we're
responding to 'xdg_surface.configure' events with
'xdg_surface.ack_configure' requests, as is necessary according to spec.
What we didn't do was to clear this state when hiding, meaning that if
we hid the surface after a configure event, but before the frame
finished and we processed the 'has_uncommitted_ack_configure', we'd try
to acknowledge the surface configuration after having destroyed the
surface.
Closes: #3262
This implementation works for both GtkListView and
GtkGridView, and by extension, also for GtkColumnView
and GtkDropDown, since those just use a list view
internally.
epoxy_dep cannot be used in a configure time check when it comes from a
subproject. Use variables set in pc file instead.
This requires https://github.com/anholt/libepoxy/pull/231.
Use the TREE_GRID, ROW, COLUMN_HEADER and GRID_CELL roles
for the various widgets involved in a GtkColumnView. To
enable this, we subclass GtkListView for the internal
list in the column view.
This is a bit different from the way things were done
in GTK 3 - we follow what was done for GtkStackSwitcher,
and make the tab bar carry the GTK_ACCESSIBLE_TAB_LIST
role, and implement Selection there.
Set up the necessary roles, relations and properties
for the tab patterns. This parallels what we have done
for GtkStackSwitcher, and implements the Tabs pattern
as described in the ARIA authoring guidelines.
Set the tablist role on the stackswitcher itself, and
the tab role on the buttons. This is another step towards
implementing the tabs pattern for GtkStack.
platform change is called from gtk_widget_set_focusable
which is likely to be called early on in init(). We don't
want to create an AT context that early if we can help
it, e.g. since it makes it impossible to override the
accessible-role with a construct property.
This requires some cleanup to remove assumptions
about accessibles being widgets in the backend,
and some code to navigate the tree with these
extra objects in between widgets.
The accessibles for stack pages have the role
GTK_ACCESSIBLE_ROLE_TAB_PANEL. This is the first
step towards implementing the tabs patterns
as described in the aria authoring guidelines
for GtkStack.
This was incorrectly reporting the toplevel surface instead of the
popup surface that was placed above it. This fixes event delivery
to popups for selecting menu items and more.
Either we or clang needs to get its shit together about this warning.
But using it during development with clang just makes actually usable
warnings get lost in a flood of -Wcast-align warnings.
This fix is correct and fixes:
1) GL textures being upside down in the inspector. They are getting
downloaded because they've been created in a different GL context
2) GL textures being upside down in the cairo renderer (same reason)
However, it breaks the testsuite. We do the flipping via the projection
matrix, but most of the shaders don't care about that.
Like we do for GdkX11. We can't use all of the public C API, but we can
expose enough type information to allow non-C developers to actually
check if they are running the Wayland GDK backend or not—plus some
additional Wayland-specific API.
The GdkWayland API takes generic GDK types and performs a run time
check, which means we need to properly annotate the actual expected
type in order to have methods recognised as such.
For the various uses of GDK_WINDOWING_QUARTZ, we need to use
alternatives from GDK_WINDOWING_MACOS.
Some minor loss of functionality is here, such as icons sent with
application menus. That can certainly be added back at a future
point.

When querying a device, we need to ensure we are providing coordinates
in the coordinate system of the surface. Further, we need to actually
provide the button and keyboard state.
This fixes some issues related to dragging scrollbars and selecting list
box rows more reliably.
Set the SELECTED state to reflect whether the selected
is selected, unselected, or unselectable. This is
enough to make selection changes appear in Accerciser.
While we are at it, also set the multi-selectable
property for the flowbox itself.
Non need to announce the same things for every context
we create, and the path is not really that interesting.
without knowing what it belongs to. I would suggest to
make it visible in the inspector instead, so you can
look it up for the widgets you are interested in.
Set the SELECTED state to reflect whether the row
is selected, unselected, or unselectable. This is
enough to make selection changes appear in Accerciser.
While we are at it, also set the multi-selectable
property for the listbox itself.
And honor it in gtk_popover_popdown(). By default, a GtkPopover
pops down automatically if a child popover was closed, if this
property is FALSE, the popover will remain opened.
We use to set the the 'password text' role for entries with
visibility = FALSE. Nowadays, we have a separate class for
password entries, so fix up the role mapping based on that.
Make text change notification work for editables, by connecting
to the ::insert-text and ::delete-text signals on the wrapped
GtkText widget, and for GtkTextView by connecting to the
corresponding GtkTextBuffer signals.
This code is more or less directly copied from GtkTextViewAccessible
and GtkEntryAccessible in GTK 3.
Since the big editable reorg, GtkText was not emitting
::insert-text and ::delete-text, as is expected of
editables. We want to use those signals for a11y
change notification, so make them work again.
This copies what was done for GtkEntry: get
the focused state from the GtkText within.
We also add a private getter for the text widget,
which was missing here.
As a companion to go with the platform_change api,
add a gtk_accessible_get_platform_state() function
that can be used by backends to get the platform
state.
This is in preparation for making entries inherit
their focus states from the text widget within.
Similar to gtk_widget_should_layout(), add a
gtk_accessible_should_present() function that backends can
use to determine whether an accessible should be presented
or not.
Ways to make a widget not presented in a11y:
- hide the widget
- set its role to NONE
- make it have a NULL AT context
We will use this in future to hide the GtkText inside
an entry, since the Text implementation will be done
by the wrapper.
We are determining editable state based on the
accessible role (although we could make it platform
state now), so cover all the roles that we use for
entry wrappers.
Add an enum for 'platform changes' to the at context
change notification mechanism. This will let us pass
along things that ARIA considers 'platform state' such
as focus or editability. The difference between the
platform state and other ARIA states is that we don't
keep the platform state separately in the at context
- backends are expected to just query the widgets.
This is just about avoiding notify listeners for
change notification.
We can use the read-only property, together with the
accessible role, to determine whether to set editable
and read-only states for at-spi. This lets us avoid
directly poking at the widgets.
ATs look at not just the implemented interfaces, but
also the states to decide what to do. It turns out that
the EditableText interface is only used by accerciser
if the editable state is set. So set it.
It is error prone to keep the same conditions in sync
in two places. Instead, just assemble the list of interfaces
as we register objects, and use when GetInterfaces is called.
Apply the Value implementation to the widgets where
we had one in GTK 3: GtkLevelBar, GtkRange, GtkScaleButton,
GtkSpinButton, GtkPaned, GtkProgressBar. To make these
work, the widgets need to set the accessible value properties.
There is some open question here whether the interface
should be implemented on the outer or the inner widget
of the entry-text pairs. For now, our hand is forced,
since only GtkText provides access to the layout that
we need for implementing many of the interface methods.
This is a not-quite-complete implementation of the
Text interface for GtkLabel. The missing parts are
anything around extents and positions, as well as
the ScrollSubstring apis.
This translates relations as far as the match.
I'm not sure yet what we can do about the fact that
atspi expects relations to be bidirectional (ie have
label-for *and* labelled-by) while aria has only one
direction.
It turns out that accerciser depends on this undocumented
method that is not in the xml at all, otherwise interface
sections in the accerciser ui never get enabled.
The ARIA spec defines the mechanism for determining the name of an
accessible element—see §4.3 of the WAI-ARIA spec.
We follow the specification as much as it makes sense for GTK to do
so:
1. if the element is hidden, return an empty string
1. if the element has a labelled-by relation set, retrieve the
label of the related element
2. if the element has a label property set, use the value of
the property
3. if neither labelled-by nor label attributes are set, we use
the role to compute the name:
- for a `range` role, we return the contents of the value of
the `value-text` or `value-now` properties
- for any other role, we return a textual representation of
the GtkAccessibleRole enumeration value
When we create the first AT-SPI context we also need to register the
accessible root on the accessibility bus. The accessible root object is
the main entry point of an accessible application, and it holds the
global state to present to the ATs that connect to the bus.
Since we need to check at run time what kind of AT context to use, we
need a hook into the whole GDK backend machinery. The display connection
seems to be the best choice, in this case, as it allows us to determine
whether we're running on an X11 or Wayland system, and thus whether we
should create a GtkAtSpiContext.
This requires some surgery to fix the GtkATContext creation function, in
order to include a GdkDisplay instance.
Does not do anything, at the moment, but it's going to get filled out
soon.
The backend is selected depending on the platform being compiled in;
since we're using AT-SPI on X11 and Wayland, and we don't have other
accessibility implementations, we currently don't care about run time
selection, but we're going to have to deal with that.
And generate the code for the DBus interfaces.
We don't want the full object manager experience, here, because we're
going to have a single object responding to various interfaces and
remote method calls. For this reason, we're not using the gnome module
in Meson to call gdbus-codegen for us: we need to use the interface info
command line arguments, and those are not available from Meson.
Like we do for GdkX11. We can't use all of the public C API, but we can
expose enough type information to allow non-C developers to actually
check if they are running the Wayland GDK backend or not—plus some
additional Wayland-specific API.

old code did.
When a widget is hidden, check harder for the keyboard focus being
contained in that widget, in order to reset it. Portions of the
focus child hierarchy may be outdated at the time, so it is more
reliable to check GtkRoot::focus (i.e. the property we intend to
update here).

We were not updating the remembered size at all when
the window is interactively resized, causing it to
snap back to its default size the next time we call
gdk_toplevel_present().
This is a bandaid fix to prevent very broken resizing
behavior, until we have properly redone toplevel sizing.
Fixes: #3076
When using the saved size because the compositor
told us to, we were forgetting to readd the margins.
The visible symptom of this was the window getting
smaller every time we went to tiled state and back.
Don't remember the surface size when we are in tiled
state either. This matches the 'fixed_size' condition
in gdk_wayland_surface_configure_toplevel.
This change fixes an issue where moving a window first
to tiled, then to maximized state and back would lead
to the unmaximized window having the tiled dimensions.
We should not emit configure events before we are realized - size
changes at this point are not relevant.
This gets rid of a mysterious emission of GdkSurface::size-changed
with a size of 52x52, that is happening when GtkWindow sets the
shadow_width before the window is mapped.

Yielding option means that if pango is built as a subproject, it will

For that to work it must be of the same type, which is "feature" instead
of "boolean" in all GStreamer modules.

We're caching two things, either a node itself being rendered, or a
parent storing a cached version of a child as rendered to an offscreen
the size and location of the parent.
If both the parent and child uses the cache this will cause a conflict in
the cache as it is currently use keying of a node pointer which will have
the same value for the node-as-itself and the child-node-of-the-parent.
We fix this by adding another part to the key "pointer_is_child" which means
we can have the same node pointer twice in the cache.
Additionally, in the child-is-rendered-offscreen case the offscreen
result actually depends on the position and size of the parent viewport,
so we need to store the parent bounds in that case.
The GtkGears widget is a bit too chatty, especially when used inside
demos like the fishbowl. Let's use g_debug() instead of g_print() for
the GL debugging message.
This adds a bunch of snazz to the gltransitions demo. It is perhaps
a bit overloaded now, but it demos everything that we can do.
Changes:
* The fire shader is now not a bin, it just renders an animating
background with no textures involved.
* The stacks don't all start on the same page.
* The shaderbin passes the mouse coordinate to the shader.
* The shaderbin allows specifying a "border" so that you can
cause effects outside the bin child (something that is new to gtk4).
* All the buttons and the stacks are now in shader-bins that runs
a wobbly-widget effect based on the mouse position that
wobbles outside the child allocation.
Now that the functions that wrap them have gone away from the public
API, we need proper annotations for the virtual functions, otherwise
languages will not have enough information on nullable arguments and
ownership transfer.
Most of the time the snapshot is less than 16 levels deep (did some testing
in gtk-demo), so lets pre-allocate 16 levels of state stack to avoid the
extra allocation most of the time.
If all your callers already initialize the array element as needed,
then we don't need to memset it to zero first.
This is pretty useful for the snapshot state stack, because due
to the per-node-type data area the elements on the stack are
quite large, but often a lot of it is not used.
This inlines the splice and reserver GdkArray calls. These are
typically only called from the gdk_array_(append/set_size) functions
anyway, and inlining the caller means we can constant propagate the
constant arguments in those calls. Its hard to get exact numbers, but
in fishbowl i noticed a significant decrease in the time spent in
the array code when pushing and poping states.
This allows us to avoid updating uniforms if that is not necessary. This
in turn allows us to sometimes reuse the same draw op by just extending the
vertex array size we draw rather than doing a separate glDraw call.
For example, in the fishbowl demo, all the icons added at the same
time will have the same time and size, so we emit single draw calls
with 100s of triangles instead of 100s of draw calls with 2 triangles.
Add adds a demo showing off GskGLShaderNode in various ways.
It has a transistion widget, using some examples from
gl-transitions.com, with child widgets being both images, a GL area
and real widgets (that let you edit the transition shaders
themselves.
It also has a fancy fire effect on hove on the buttons.
For vulkan/broadway this just means to ignore it, but for the gl
backend we support (with up to 4 texture inputs, which is similar to
what shadertoy does, so should be widely supported).
A GskGLShader is an abstraction of a GLSL fragment shader that
can produce pixel values given inputs:
* N (currently max 4) textures
* Current arguments for the shader uniform
Uniform types are: float,(u)int,bool,vec234)
There is also a builder for the uniform arguments which are
passed around as immutable GBytes in the built form.
A GskGLShaderNode is a render node that renders a GskGLShader inside a
specified rectangular bounds. It renders its child nodes as textures
and passes those as texture arguments to the shader. You also pass it
a uniform arguments object.
Print out the full assembled shader sources when
GSK_DEBUG=shaders is given. This is very verbose,
but may be useful to see what we actually pass
to the compiler.
This way the child widgets can rely on the renderer (for example what
type it is) to decide details about how they render (such as if they
should use OpenGL shaders).
This adds a gsk prefix to the stuff in the preamble, as we want to
avoid it conflicting with things in the main shader. Especially once
we start allow some customization of shaders.
Almost always the source is created by combining various sources, which
means the line numbers in the error messages are hard to use. Adding
the line numbers to the source in the error message helps with this.
There is no real reason to have this on the side indexed via the
index, as it is stored next to each other anyway. Plus, storing them
together lets use use `Program` structures not in the array.
This property was only used until now when
there was neither an icon nor a label set,
for arrow direction and popover placement.

label shows an arrow at the right (in LTR)
of the label. Allow disabling the arrow or
changing its direction using the direction
property, to have a way to restore a Gtk3-
like look or to improve popover placement.
Fixes#2811.
Kinetic scrolling (and begin/end tracking) broke with commit cab1dcb696
since the pointing device used on X11 does not get as much GdkInputSource
granularity as the source device used to have in GTK3.
Actually this is kinda pointless, devices incapable of smooth scroll
should send discrete events, without those devices in the picture, we
want kinetic scroll to apply on every other device capable of smooth
scroll, so just do that.

The texture that produce is upside-down, compared to what
GSK expects, so flip things around with a transform.
This fixes the shadertoy demo being upside-down after a
recent fix to avoid downloading and reuploading the texture.
... or gradients or borders or shadows. Instead, ensure that affines
have non-negative scale factors. Otherwise add a transform node.
The only place where this check is not necessary is color nodes, but
special casing them seems not worth it.
I added libcloudproviders to the base image, but
now I see that we already enabled libcloudproviders
in the build anyway, so I'm a bit confused.
Fixes: #2480
"inout" for the parameter ITER passed. This means that bindings would misjudge what
the function does. In the case of guile-gi, it would be misjudged for a predicate,
see gulie-gi bug 87.
I found that the gears demo was spending 40% cpu
downloading a GL texture every frame, only to
upload it again to another context.
While the GSK rendering and the GtkGLArea use different
GL contexts, they are (usually) connected by sharing data
with the same global context, so we can just use the
texture without the download/upload dance. This brings
gears down to < 10% cpu.
Currently, only if PangoFT2 is present and used it is supported
to retrieve the languages that are supported by a particular font.
If we don't have PangoFT2, remove the language filtering and the
sample text selection.

Copy the format conversion code from GdkMemoryTexture
so we can produce all formats, and test them all.
The upload fast paths assume that the stride is a
multiple of four, so some of the padding values cause
it to fail. Apart from that, things seem to work for
all combinations.
Create textures with various characteristics (alpha, premultiplication,
stride) that trigger different code paths in the gl texture upload
function, and show the resulting images. If all goes well, they all
should look the same.
On my system, this tests texture upload for memory formats
GDK_MEMORY_B8G8R8A8_PREMULTIPLIED, GDK_MEMORY_R8G8B8A8, and
GDK_MEMORY_R8G8B8, and it works with both gl and gles.
With the exception of gtk_buildable_get_id(), those are only used
to construct objects from XML descriptions, which is functionality
internal to GTK.
The API is therefore unlikely to be missed, and keeping it internal
means they can no longer unintentionally shadow object methods in
bindings with less namespacing; for example it's currently ambiguous
whether `infoBar.add_child()` refers to gtk_info_bar_add_child() or
gtk_buildable_add_child().
https://gitlab.gnome.org/GNOME/gtk/-/issues/3191
GtkBuildable's get_name()/set_name() methods may shadow
GtkWidget's methods. Avoid that by renaming the API to
get_buildable_id()/set_buildable_id(), which also reflects
the name of the XML attribute the API refers to.
https://gitlab.gnome.org/GNOME/gtk/-/issues/3191
Drop gtk_column_view_column_new_with_factory and
just make gtk_column_view_column_new accept a
nullable factory. This follows what we've been
doing elsewhere.
Update all callers.
The priv->in_button state that used to be relied upon for pointer
events has been reduced over time to a broken state, since the button
does not track crossing events anymore.
Make the coordinate-based checks apply for pointer events too, besides
touch events. This fixes GtkButton mistakenly emitting ::clicked with
pointer button releases outside the widget.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3121
Claiming early makes the contents unable to react to the touch press
event. Do this on GtkGestureDrag::update past a threshold, so the
child widget(s) can claim before the scrolledwindow does.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3125
This API is kinda stuck in the GdkEvent days, we now negotiate ownership
of the input sequence via GtkGestures. Remove it as it reflects a way to
work that was not exactly accurate and it will turn plainly wrong soon.
There is nothing really special about this code, its just a helper for
uploading pixel data to opengl, and we're not really in the business
of doing opengl-specific helper functions.
Do custom uploads rather than using gdk_cairo_surface_upload_to_gl(),
because this way we avoids a roundtrip (memcpy and possibly conversion)
to the cairo image surface format.
The gdk-pixbuf non-rgba format can be directly uploaded without
conversion.
The rgba format needs alpha premultiplication though, which is not
supported by GL during upload.
GLES doesn't support the GL_BGRA + GL_UNSIGNED_INT_24_8 hack that
we use on desktop OpenGL to upload textures directly in the cairo
pixel format. This adds the required conversions to all the places
that currently need it.
We also add a data_format to the internal gdk_gl_context_upload_texture()
function to make it clearer what the format are. Currently it is always
the cairo image surface format, but eventually we want to support other
formats so that we can avoid some of the unnecessary conversions we do.
Also, the current gdk_gl_context_upload_texture() code always converts
to a cairo format and uploads that like we did before. Later commits
will allow this to use other upload formats that gl supports to avoid
conversions.
This is the default OpenGL format, and in fact the only pixel format
that GLES supports uploading as. Actually, the premultiplied part is
really just about how we use the textures, but all textures in GTK
are premultiplied.
Just always tell the title and cell widgets to
clip their children to the right size. Otherwise
we risk things getting out of sync and unintended
overdraw.
Fixes: #3179
If we just parse a color, like image(#FFF), avoid allocating the
GPtrArray to store images. This happens in Adwaita for background images
of backdrop buttons. We save around 70 GPtrArrays this way.
The centered layout of the font previews don't look appealing
and make it harder to judge the relative width and weight of
the individual styles.
Fixes: #3188
In gtk_tree_view_build_tree with recurse=TRUE, the TEST_EXPAND_ROW
signal might invalidate the child iterator. Getting the iterator after
the signal (instead of before) fixes the issue.
Fixes https://gitlab.com/inkscape/inkscape/-/issues/1879
When claiming a sequence in a gesture signal handler,
the expected result is that GtkGesture::handle-event
returns TRUE, causing the event to not be propagated
further.
This doesn't work for button release events, since
gtk_gesture_handle_event does the following:
add point
emit ::update
remove point
check claimed status
The ::update signal is where the application code
claims the sequence. But removing the point purges
the sequence from the gestures memory, so checking
the claimed status returns FALSE.
This patch fixes things to behave as expected, by
checking the claimed status before removing the point.
currently when mouse clicking on a column header
to sort it it is grabbing keyboard focus, this
should not happen, keyboard focus should remain
where it was before. This can be seen on the
GtkFileChooser widget, when having the keyboard
focus on the file list items and clicking on a
column header to sort it the keyboard focus is
now on the header.
At least from GTK v3.22.30, the code disallows attempts to print PDF and
PS files using the LPR backend. Although it is not easy or possible for
GTK to determine if the printer can print these formats by querying lpr,
the print backend should allow lpr to try.
There are two uses cases:
- A filter is being used by lpr, specified in the printcap file, to process the
files prior to printing them.
- The printer can print PDF and PS files directly. There are many printers that
can print these formats, so GTK should allow for the possibility.
