This fixes potential runtime crashes in some somewhat unlikely
configurations, like a modern compositor but gtk built against an old
wayland protocols version.
We only need v2 for the tiling fixes, so request that.
On GTK3 the msys2-mingw64-meson job is failing due to error:
mingw-w64-x86_64-pkg-config and mingw-w64-x86_64-pkgconf are in
conflict. Remove mingw-w64-x86_64-pkgconf? [Y/n]
To fix this we change required package pkg-config to pkgconf, which
is what the GTK4 branch also uses.
cairo_image_surface_get_width() and cairo_image_surface_get_height()
return the image size that's in the device pixels.
On the other hand, _gdk_wayland_display_create_shm_surface() takes a
surface size in the logical pixels.
Given that _gdk_wayland_display_get_cursor_for_surface() provides the
desired surface size in device pixels, a much bigger shm surface is
created, which then breaks damage tracking code in
gdk_wayland_device_update_window_cursor().
Fixes#6242
And get the embedder before continuing, as the backend-specific
get_monitor_at_window () only knows about its own windows.
In order to check for offscreen windows, we introduce a new function
gdk_window_is_impl_offscreen (). Unlike gdk_window_is_offscreen (),
it doesn't rely on the window_type field, but actually checks whether
GDK_WINDOW_IMPL_GET_CLASS (window->impl) is GdkOffscreenWindow.
See previous commit for informations.
Checking for offscreen windows with gdk_window_is_offscreen ()
is not enough in this case. What we want here is that the impl
classes match, as backends are meant to know only about their
windows. Instead gdk_window_is_offscreen () checks whether the
GdkWindow.window_type field is GDK_WINDOW_OFFSCREEN.
In the case of child windows in offscreen windows, the window
type is GDK_WINDOW_CHILD, even though their impl is still
GdkOffscreenWindow.
So actually check whether GDK_WINDOW_IMPL_GET_CLASS (window)
matches GDK_WINDOW_IMPL_GET_CLASS (parent).
We may also consider getting the toplevels from child windows,
as transient-for relationships are really about toplevels, but
child windows doesn't seem to cause problems in practice.
This was basically done copying the gtk4 version and keeping the changes
that weren't gtk4 specific.
Fixes#6224 (the chooser doesn't close but we don't crash or such)
The Adwaita cursor theme is moving to shipping just standard cursor
names, so we should fall back to 'default' instead of 'left_ptr' if
a named cursor can't be found.
Fixes: #6259
Representing these by systematic names gir1.2-*-dev, and perhaps
eventually separating them into their own binary package, will help to
enable cross-compilation with GObject-Introspection removed by a build
profile.
Helps: #1030223
gdk_keymap_get_entries_for_keyval is supposed to return FALSE when no
keys were found. Do so to prevent careless clients (that don't check
n_keys too) from crashing.
