Instead of hardcoding gtk-xft-antialias, use SPI_GETFONTSMOOTHING to
determine whether antialiasing is enabled.
Make gtk-xft-rgba query more complex - try to determine display
orientation, then use that to rotate subpixel structure. This
won't help with monitors that have naturally vertical subpixels,
but should improve things for monitors that are rotated (as long
as Windows display settings are adjusted accordingly).
Partially fixes#1774
This reverts commit fc2008f240.
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.
The order in which the resources get embedded matters for reproducible
builds. In the Meson build system, gen-gdk-gresources-xml already sorts
the list, but in the Autotools build system they were previously taken
in readdir() order.

This means it'll always be as up to date GdkWindow::width/height. We
still skip the resize for non-configured windows though, to avoid
mapping with the wrong size.
The commit f06ee688fe also accidentally
removed the unconfigured size setting completely, so this essentially
adds it back, but always sets it.
Closes: https://gitlab.gnome.org/GNOME/gtk/-/issues/2582
So now we essentially only inhibit the premature resize for toplevel
windows, where it is most crucial. For popups, this didn't work for two
reasons: we relied on the owner of the popup (application) to resize
according to the configured size. For custom popup operators like
Epiphany and LibreOffice, this didn't work out well, since they simply
didn't.
Making gdk do it for them in case they didn't themself did make the
popups show up properly, but there were still some weirdness in
LibreOffice where tooltips didn't still didn't get the right size. So,
even though the size set by application may be different from the one
later configured by the display server, let the applications have their
way and see their resize result immediately. It's fairly likely to be
what they eventually get anyway.
Closes: https://gitlab.gnome.org/GNOME/gtk/-/issues/2583
Who knows who might use this for something, so lets make the
unconfigured size slightly more predictable. This doesn't fix anything
known to be broken though.
With the fixes from !1638, it shouldn't be possible for this to happen
any more. However, non-positive sizes make no sense regardless, so if
this does somehow happen, let's make sure *something* reasonable happens.
The practical result of this assertion being hit is that we emit a
critical warning and then behave the same as if !1634 had been merged,
which is known to solve the issue for the submitter.

We get the unconfigured size request either with or without the shadow
margin already configured, so to get some consistency with the 'saved
size', cut away any potential shadow margin from the size before
storing.
Then when using, add it back, so we always create a configure event with
the correct size.
Closes: https://gitlab.gnome.org/GNOME/gtk/-/issues/2576
There is no way for custom Wayland surfaces to get configure events, so an
initial configure event should not be required to resize a custom surface.
Fixes#2578.
With C compilers defaulting to -fcommon, this isn't an issue, but
upcoming compilers (GCC 10 and Clang 11) will default to -fno-common,
ending up with duplicate definitions of this variable.
When we `Alt+Tab` away from a GTK application, it loses keyboard focus.
If we don't clear the modifiers, events from other devices that we
receive while unfocused will assume `Alt` is still pressed. This results
in e.g. Firefox navigating through the history instead of scrolling the
page when using the mouse wheel on it.
We don't get any information about modifiers while we are missing
keyboard focus, so assuming no modifiers are active is the best we can
do.
The shell sends us a modifier update immediately before we regain
keyboard focus, so the state shouldn't get out of sync.
Fixes https://gitlab.gnome.org/GNOME/gtk/-/issues/2112
We're normally going from a fixed size to a floating state when we're
using the saved size, meaning we're practically always going towards a
state where the shadow margin will non-empty. However, if we don't
include any margin when creating a new configure request, we'll end up
resizing to a slightly smaller size as gtk will cut off the margin from
the configure request when changing the window widget size.
This wasn't visible when e.g. going from maximized to floating, as we'd
add the shadow margin at a later point, which would effectively "grow"
the widnow size, but when we're going from tiled to floating, we both
start and end with a non-empty shadow margin, meaning we'd shrink ever
so slightly every time going between tiled and floating.
We should never save a size when we're tiled, just as we shouldn't when
we're maximized. This fixes returning to the correct floating size after
having been tiled or maximized.
If a window is configured with a fixed size (it's tiled, maximized, or
fullscreen), ignore any resize call that doesn't respect this. The set
size will instead be saved, when appropriate, so that the new size is
used when e.g. unmaximizing.
This makes it possible to call 'gtk_window_resize()' while the window is
maximized, without the window actually changing size until it's
unmaximized. Changing size to a non-maximized size is a violation of the
xdg-shell protocol.
An application may want to set a fallback size of a window while still
mapping maximized. This is done by calling gtk_window_resize() before
gtk_window_maximize() and before gtk_window_show(). When the window is
mapped, it should have a maximized size, and if it eventually is
unmaximized, it should fall back to the size from the earlier
gtk_window_resize() call.
What happens before this commit is that the initial window size ends up
respecting the first gtk_window_resize() dimensions, and not the window
dimension configured by the Wayland display server (i.e. maximized
dimensions).
Fix this by postponing any configure events until we received our
configuration from the display server. If we got one with a fixed size
(e.g. we're maximized, tiled etc), we use that, otherwise we look at the
one that was previously configured by gtk which corresponds to the
"preferred" size when not being maximized.
This fixes Firefox being started in a maximized state when using the
Wayland backend.

gtk+-3.24.14 with quartz backend fails to compile on macOS when using
a case-sensitive file system. The cause for the compilation error is a
simple typo in line 26 of `gdk/quartz/gdkquartz-gtk-only.h`. The
AppKit framework is included there with `<Appkit/Appkit.h>` instead of
`<AppKit/AppKit.h>`, which is fixed with this commit.

If NULL is returned, probably the client shouldn't advertise the
mimetype. Make it sure we forget entirely about the attempt to
cache this mimetype, as it'll be mistaken as pending otherwise.
Dropping this cached selection will in consequence close the fd
of all pending readers, which seems appropriate for NULL content.
https://gitlab.gnome.org/GNOME/gtk/issues/2456
The only way to have G_IO_ERROR_CANCELLED in the write callback
goes through having the array of pending writers already cleared.
It should not access the invalid AsyncWriteData and StoredSelection
in that case.
gdk_window_impl_quartz_release_context () can be called with a NULL CGContextRef. This causes CoreGraphics assertion failures when debugging a Gtk application in Xcode, as the code was blindly passing that NULL to CGContextRestoreGState () and CGContextSetAllowsAntialiasing (). Given that the matching pair of CGContextSaveGState () and CGContextSetAllowsAntialiasing () calls are already checking for a NULL CGContextRef, it seems reasonable to wrap these calls in a NULL check.
Cache separately the selection contents for each given window/selection/atom
combination, and keep the requestors separate for each of those.
This allows us to incrementally request multiple mimetypes, and dispatch
the requestors as soon as the data is up. This stored selection content is
cached until the selection owner changes, at which point all pending readers
could get their transfers cancelled, and the stored content for the selection
forgotten.
For a given OpenGL context, macOS in particular does not support enumeration / detection of OpenGL features that have been promoted to core OpenGL functionality. It is possible other drivers are the same. This change assumes support for GL_ARB_texture_non_power_of_two with OpenGL 2.0+, GL_ARB_texture_rectangle with OpenGL 3.1+ and GL_EXT_framebuffer_blit with OpenGL 3.0+. I failed to find definitive information on whether GL_GREMEDY_frame_terminator has been promoted to OpenGL core, or whether GL_ANGLE_framebuffer_blit or GL_EXT_unpack_subimage have been promoted to core in OpenGL ES. This change results in a significant GtkGLArea performance boost on macOS.

When a device is added, there are two references to it by the device
manager, the initial one and the one used for the id_table. Removing a
device only removed the reference added by the id_table resulting in the
GdkDevice being leaked.

On Wayland, opening and closing a `GdkDisplay` generates a coupe of
warnings at runtime:
```
GLib-GObject-WARNING **:
invalid cast from 'GdkWindowImplWayland' to 'GdkWindow'
GLib-GObject-WARNING **:
invalid cast from 'GdkWaylandWindow' to 'GdkWindowImplWayland'
```
This is from `gdk_window_impl_wayland_finalize()` which tries to cast
the given GObject to a `GdkWindow` while it's a `GdkWindowImplWayland`.
Use the correct type casting of objects to avoid the warnings.
The sed -i flag is non-standard, and may not be available in all
implementations.
The meson build already requires wayland >= 1.14.91 and uses
private-code, so just do that in the autotools build as well.
Window scale can change at runtime. If cairo_surface is already
created for root window gdk_pixbuf_get_from_window will return
wrong image.
_gdk_x11_screen_set_window_scale already updates window_scale for
root window, update also cairo_surface device scale.

Also ensure that gdkquartz-gtk-only.h is included in distribution
tarballs.
Failing to include gdkquartz-gtk-only.h in gdkselection-quartz.c
caused the compiler to not set the extern storage class on the

Otherwise the icon "jumps" to the cursor position with its top left when
the animation starts.
This is especially visible if the dragged item is big, like when dragging
mails in Thunderbird.
With some GL drivers, it may be the case that menus are not shown
correctly in fullscreen GL windows because DWM is deactivated in the
process.
Force WS_BORDER to be applied to the fullscreen GL window so that we have
a small 1px border when needed (by setting an envvar), so that DWM does
not get deactivated, hence enabling the menus to show. Also, when we
force WS_BORDER to be applied in this situation, we also deliberately
place the window just outside the top lefthand corner of the screen by
1px and make the window 1px larger than the screen size, so that we
effectively hide the 1px border from view.
Fixes issue #1702.
We also need to force redraw of the whole window when we are using
EGL/ANGLE during un-fullscreen, so that we do not get glitches in the
resulting window.
_gdk_win32_display_convert_selection() does not return anything,
it generates a selection notify event instead. Depending on how
successful it was, the event will have property=GDK_NONE or
property="GDK_SELECTION".
property="GDK_SELECTION" is the default return value for successful
cases, and it tells GTK to grab the data that GDK previously deposited
using selection_property_store().
The problem is that the clipboard branch of this function calls
open_clipboard_timeout(), which can't return anything meaningful (it's
normally a timeout function), and thus doesn't know whether the function
succeeded or failed. Due to my oversight, this resulted in GDK
generating two selection notification events - one from inside of
open_clipboard_timeout() (with the right property, if successful),
and one from the catch-all last line (always defaulting to "GDK_SELECTION").
This caused issue #2223, where GTK only expected exactly one
notification per request, and got confused because it was getting two.
I've looked at the code in open_clipboard_timeout(), and it seems to me
that it always generates a notification (a successful one or an
unsuccessful one). Thus the branch of the function that calls it
directly does not need to follow up with a catch-all notification and
can just return.
This seems to be fixing issue #2223, at least for me, but i'm not
entirely sure that this will not have any adverse side-effects.
Clipboard handling in GTK3 is a complicated mess.
Instead, use the standard library().
This is a meson best practice.

It can be tricky to deal with both, so let's give an example of using

For page up/down events (Fn+up_arrow and Fn+down_arrow on macOS)
gtk_im_context_filter_keypress() currently returns TRUE when im-quartz is
used. This means these events get removed when this function is used
(happens e.g. with the Scintilla text editing library).
Adding scrollPageDown: and scrollPageUp: into GdkQuartzView seems to
resolve the issue as these seem to get called instead of the already
present pageUp: and pageDown:.
We are interested in changing the owner window, so the upper bits know
that it is not this client who owns the selection. We are still not
interested in unsetting the selection desktop-wide though, so only avoid
emitting the relevant events then.
The same reasonings than in commit 7a891eeb6d apply otherwise.
Use RemoveClipboardFormatListener() and AddClipboardFormatListener().
These APIs remove the need for us to maintain the integrity of the
clipboard chain, which turned out to be problematic for some reason
that is yet to be identified.

This should just be called by the upper layers (and result in
wl_data_device.set_selection, etc). We should not trigger this within

This should only be explicitly unset (face to the windowing) on
gdk_selection_owner_set() with a NULL window. Other circumstances

The xdg_output.done event is deprecated in xdg-output v3, so clients

However, applying the changes on the fist wl_output.event when using

updates may follow.

I was not getting any gtk+ profile markers output from the frame clock
when I was profiling an OpenGL app (gnome-hexgl). I debugged this and
it turns out that the profiling depends on getting the _NET_WM_FRAME_TIMINGS
event from the compositor, and once we switched to OpenGL rendering
this never appeared.
It turns out the reason it didn't is that the compositor only does
so if the client increases the counter tied to the window, and the
x11 gdk code has this optimization where if we do a draw pass
but nothing is actually drawn we don't update the counter.
Unfortunately the detection of whether something was draw or not
is based on some cairo surface hack that breaks when we render with
OpenGL instead. The fix is to just always update the counter if
we're drawing with OpenGL.
This was added with https://bugzilla.gnome.org/show_bug.cgi?id=148032
to make gtk compile against X11R5, see commit 3b9a31df0
That release is >20 years old now, so we can safely remove it.
The motivation for this is to remove any checks that we don't have in the
meson build.
This fixes an issue where stylus proximity in/out events emulate enter/leave events.
The emulated events didn't contain the correct slave device and therefore the
resulting device class was set incorrectly. Crossing event emulation now also
works with slave devices.
