Wayland subsurfaces can have other native window parents, but those need
to be destroyed along with the rest of the window hierarchy otherwise
an assert() is reached.
https://bugzilla.gnome.org/show_bug.cgi?id=774915
gdk_window_get_toplevel() walks up the windows tree looking for the
corresponding toplevel window, but needs to account for subsurfaces as
well on Wayland.
https://bugzilla.gnome.org/show_bug.cgi?id=775319
Now that subsurfaces can be created as child of another GdkWindow (and
not just the root window), they must be placed according to the location
of their parent, i.e. the abs_x/abs_y must be updated and taken int
account when placing and moving subsurfaces under Wayland.

The functions gdk_pixbuf_get_from_window() and
gdk_cairo_set_source_window() are unreliable and depend on the windowing
system (they work great on X11 and Win32, less so on Quartz and Wayland).
With the switch to new drawing API and OpenGL, we can definitely no
longer support a generic way to snapshot windows.
People should either write windowsystem-specific code or draw their
widgets directly - like with gtk_widget_draw() - if they need to get a
rendering.
Under Wayland, a subsurface can have another surface as parent, but
gdk would not allow native windows if the parent is not the root window.
Allow native subsurface for all parent under Wayland, not just for the
root window.

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

As in the last commit on gdkdisplay-win32.c, we need to define that to be

... to be for Vista (0x0600) or later. This is so that the necessary
items in the Windows headers be activated so that the code will build
properly on mingw-w64, and we already require Vista or later for GTK+.

For wayland clients, the startup notification ID is currently only set
from the DESKTOP_STARTUP_ID environment variable. As that variable is
only set for clients launched via exec(), startup completion is not
indicated correctly for DBus-activated applications unless an explicit
ID is specified - usually that is not the case, as the default handling
uses gdk_notify_startup_complete().
To address this, we need API to set the startup notification ID from GTK
as we have on X11.

This way we can recommend that applications use the
fullscreen_on_monitor() API on both X and Wayland otherwise they'd

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

Now that GTK+ is built as a single DLL, and the .lib that is built is
gtk-4.lib, we need to update the autotools sections in generating the
NMake Makefile snippets so that we can have the correct commands and flags
for building the .gir files, which will all now link to gtk-4-vsXX.dll (or
so).
Now that the autotools build folded the GDK/GSK bits into the main GTK+
DLL, there are some updates that need to be done for this. We need to:
-Fold the DllMain() of GDK-Win32 into the main GTK+ DllMain(), as we need
the HINSTANCE to register the window. We can't have two DllMain()'s in a
single DLL.
-Remove the GDK rc(.in) files, as that is not used anymore. Make the GTK+
.rc(.in) file load the gtk.ico GTK+ logo file instead so that we still
get the GTK+ logo for the application icon by default. Update the
autotools build files as well.
-Revert commit b9f9980 as LRN pointed out in comment 25 in bug 773299, as
GTK+ is now a monolithic DLL, and we ought not to export this private
function.

gdk_wayland_window_attach_image() is normally called from
gdk_window_end_paint() to notify the compositor of newly staged drawing.
If any of the drawing code inadvertently dispatches the wayland event
loop (for instance with a gdk_flush() call), then it's possible that by
the time gdk_window_end_paint() is called, the staged drawing is already
destroyed.
This commit bypasses the attach_image call in scenarios where the staged
drawing is prematurely dropped.

Commit d249e77 (API: screen: Remove gdk_screen_is_composited()) attempted
to update the GDK-Win32 for the removal of the API, but some parts were
missed. This updates the code so that things continue to build and run.
https://bugzilla.gnome.org/show_bug.cgi?id=773299
Switch code to use gdk_display_is_composited() instead.
The new code also doesn't use a vfunc to query the property but rather
requires the backend to call set_composited()/set_rgba() to change the
value.
Also add properties for those two properties.
The first property is equivalent to checking if an RGBA visual exists,
the 2nd is equivalent to gdk_screen_is_composited().
Update the GDKGL implementation:
-Allow legacy contexts to be created.
-Use finer-grained attributes to ask for a pixel format when possible,
which also adds support for anti-aliasing
In fact the changes here are required for GTKGL to work properly on
Windows for 4.x.
Note that creation of gles contexts is not done here, as the system does
not support such contexts directly on Windows, but only through means such
as ANGLE, which is a totally different issue here.

This merged gtk, gdk and gsk into one library, making it possible to
have internal private APIs between gtk them, as well as producing more

We now need C99 features from the compiler which are only supported by
Visual Studio 2013 and later, so drop the MSVC 2008~2012 projects, and make
the baseline supported Visual Studio version be 2013. Update the build files
as a result.
These complicate a lot of GdkWindow internals to implement features
that not a lot of apps use, and will be better achieved using gsk.
So, we just drop it all.
Now that the use_es field is an int with a possible negative value, we
cannot use it its truth value directly; we need to check if it's a
positive value, instead.
GDK defaults to asking for an OpenGL 3.2 Core Profile, but if we get a
legacy profile from the underlying windowing system, the OpenGL version
will be fixed to 3.0. If that happens, we need to set the legacy bit on
the GdkGLContext, since that bit will be used to determine the version
and type of GLSL shaders that will be used by application and toolkit
code alike.
We've already set ->use_es correctly at context creation time, all this
can possibly do is change our mind about what kind of GL we're using.

xdg_shell v6 allows grabless popups, whose behavior is not that
different from override redirect windows with no grab to take
keyboard input (and pointer events outside).
This means we can relax the requirement to have a grab before
creating an xdg_popup. The warning is still useful to have so
people stop relying on gdk_window_show();gdk_device_grab() being
an ok pattern to popup a window, it's been moved to wayland
implementation of gdk_device_grab() instead, so we warn if trying
to grab a GDK_WINDOW_TEMP window that's already visible.

This updates all the projects files to be be named appropriately as we move from GTK-3.x to 4.x,
and updates the autotools files so that things are distributed and generated properly.
Also remove deprecated/gtkstatusicon-quartz.c from gtk/Makefile.am, as that was causing 'make dist'
to fail as that file has been removed.
This fixes 'make dist' with the updated existing project files in proper order.
Note that this does not include the new GSK, which will be added later, so the project files do
not yet build the whole stack on Visual Studio at this point.
The surface-to-GL upload logic has become more complicated with the
addition of the GLES code paths; it's more logical to have a public
utility function that can be called from GDK users, instead of copy
pasting the whole thing multiple times.
This is an attempt to get rid of gdk_window_new() for more specific use
cases. These 2 are for client-side windows - regular ones and input-only
ones resepectively.
So far all those functions just call into gdk_window_new().
Just like GLib, GTK+ would benefit from getting warnings and errors from
the compilers.
We check various, common warnings, especially for a future use of C99;
additionally, we promote some warnings to errors, in order to ensure
that simple mistakes are caught during the development phase, before
they are submitted to the code repository.
The update tracking code was ugly and using deprecated drawing APIs. It
was also in the wrong place.
So instead of trying to keep it working, I'll remove it. We need to find
a better way to put it and make it work there.
And with it, gtk_widget_get_visual() and gtk_widget_set_visual() are
gone.
We now always use the RGBA visual (if available) and otherwise fall back
to the system visual.
The cursor was set using gdk_window_set_cursor() even in
gdk_window_new().
So instead of having yet another flag, just make the users of that flag
call gdk_window_set_cursor() directly after the window was created.
X11 was the only backend to support it and people can just override it
using XSetClassHint() directly.
The docs already advertised the function as "Do not use".
Keep the existing call to XSetClassHint() in place, so that we keep
setting the same values as in GTK3.
... and gdk_screen_get_window_stack().
Those functions were originally added in
5afb4f0f11 but do not seem to be used as
they are not implemented anywhere but in X.
As GDK is not meant to fulfill window management functionality I'm going
to remove these functions without replacements.
... and gdk_screen_get_width_mm() and gdk_screen_get_height_mm() and
the shortcut counterparts that call these functions on the default
screen.
Modern display servers don't provide an ability to query the size of a
screen or display so we shouldn't allow that either.
Nobody ever does a NULL check there so all that causes is crashes. So
we better return a non-primary monitor than NULL.
Fixes gdk-wayland always returning NULL.
ClutterEmbed on Wayland uses a subsurface and relocates it on configure
events, but when placed within a scrolled window, no configure event is
emitted and the ClutterEmbed subsurface remains static.
Emit a configure event for native windows in GdkWindow's internal
move_native_children() so that custom widgets relying on configure
events such as ClutterEmbed can relocate their stuff.
Similarly, when switching to/from normal/maximized/fullscreen states
which change the shadows' size and possibly shows/hides a header bar,
we need to emit a configure event even if the abs_x/abs_y haven't
changed to make sure the subsurface is size appropriately.

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

Setting the shadow width earlier as done with commit 4cb1b96 to address
bug 771561 proved to cause unexpected side effects on size_allocate
signal propagation.
As the window is sized correctly earlier, the size_allocate signal is
not emitted again in gtk_widget_size_allocate_with_baseline() which
prevents clutter-gtk from relocating its child widget correctly.
To avoid this issue, revert commit 4cb1b96 but make sure the values
passed as min and max size is never negative in Wayland as this is a
protocol error.
With this, the min/max size will be wrong for a short amount of time,
during the state transition, until the shadow width is updated from
gdk_window_set_shadow_width().
This approach is much safer and less intrusive than changing the
size_allocate logic in gtk.
This reverts commit 4cb1b9645e.

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