By using wl_output_release(), GDK lets the compositor to clean up the
output global more nicely.
For example, currently, most compositors remove the global and then
destroy it later after N seconds expire. With this, the compositor could
experiment with destroying the output global once all its resources are
destroyed.
`apply_monitor_change()` already calls `update_scale()`.
Note that this only affects old compositor versions (see
`should_update_monitor()`) so it's just a minor cleanup.
Starting with the Wayland protocol wl_pointer >= 8, discrete axis
events have been deprecated in favour of high-resolution scroll event.
Add a listener for high-resolution scroll events and, for backwards
compatibility, handle discrete events as discrete*120.
The GdkToplevelSize struct already has the concept of "bounds", which
means the largest size a window should reasonably have. It's practically
the equivalent of the monitor the window is intended to be mapped on,
with the "struts" (e.g. panels) cut out. It's used by GTK to use this
information to calculate a default window size that is "lagom" (swedish;
not too large, not too small).
This makes the hotspot of DND surfaces work when using the Vulkan and
OpenGL renderers.
This bumps the CI image used to the newly built image. This is needed to
install a new enough libwayland-client.so needed for wl_surface.offset.
This is done by adding wayland as a meson subproject, building it
on-demand if the version in the system is not new enough. As
libwayland-client.so is pulled in implicitly when linking to gtk4, the
compile step needs LD_LIBRARY_PATH set to make ld find the right library
to link to.
We now have a boolean setting that determines whether the high-contrast
theme should be used. Support it by automatically setting the existing
`gtk-theme-name` and `gtk-icon-theme-name` properties when enabled.
With that, it is no longer necessary to change the regular theme settings
for high-contrast, so toggling between high-contrast and a non-default
theme finally works reliably.
Ping/pong serials are not meant to be interpreted as user input serials
(e.g. those given back later to the compositor on grabs). As a matter
of fact, Mutter uses a different count (i.e. timestamps) in these, so
using these serials may confuse the compositor into denying certain
operations like DnD.
Instead of
Display::make_gl_context_current()
we now have
GLContext::clear_current()
GLContext::make_current()
This fits better with the backends (we can actually implement
clearCurrent on macOS now) and makes it easier to implement different GL
backends for backends (like EGL/GLX on X11).
We also pass a surfaceless boolean to make_current() so the calling code
can decide if a surface needs to be bound or not, because the backends
were all doing whatever, which was very counterproductive.
The vfunc is called to initialize GL and it returns a "base" context
that GDK then uses as the context all others are shared with. So the GL
context share tree now looks like:
+ context from init_gl
- context1
- context2
...
So this is a flat tree now, the complexity is gone.
The only caveat is that backends now need to create a GL context when
initializing GL so some refactoring was needed.
Two new functions have been added:
* gdk_display_prepare_gl()
This is public API and can be used to ensure that GL has been
initialized or if not, retrieve an error to display (or debug-print).
* gdk_display_get_gl_context()
This is a private function to retrieve the base context from
init_gl(). It replaces gdk_surface_get_shared_data_context().
Remove a boatload of "or %NULL" from nullable parameters
and return values. gi-docgen generates suitable text from
the annotation that we don't need to duplicate.
This adds a few missing nullable annotations too.
Width and height of a GdkMonitor are derived via wl_output which
talks about physical dimensions of a device and compositors usually
implement this as the untransformed values (e.g. weston, wlroots).
Since the GTK client has no way to figure out if a monitor was rotated,
transform the physical dimensions according to the applied wayland
transform to have the physical dimensions match the logical ones.
Mutter flips the physical dimensions itself but doesn't announce the
transform so this shouldn't break anything there.
Rewrite this in a way that doesn't depend on kernel
header defines at the time the wayland scanner was run.
This was causing the build to break on Centos 8, where
a bunch of fourcc formats are missing.
When we don't get stettings from the portal, the current
fallback is 'awful fonts'. There is no need for that. Instead,
set the fallback values to grayscale antialiasing with slight
hinting.
... until all globals have been received.
The dependency tracking introduced in 4e9be39518 only allows to
specify required globals and processes the closures as soon as
the requirements have been met. There are, however, also optional
dependencies - most notably the primary_selection protocol.
Currently we rely on the fact that compositors like Mutter announce
it before `wl_seat`, even though the order is not specified in
the spec.
Process globals closures only after all globals have been announced,
so optional dependencies can be accommodated.
Closes https://gitlab.gnome.org/GNOME/gtk/-/issues/3791
Commit 97b5fad131 was a forward port from a gtk3 patch, but the hunk
was applied on the wrong bits of code.
Ensure the initialization paths also do mark settings read from the
portal as valid, so the checks for optional/newer settings actually have
the expected result. It is also desirable to mark settings as valid
after configuration changes (as that patch did effectively do), but not
enough to fix all situations.
Use the infrastructure already available to look up keys, instead.
This does the right thing and looks up the setting across all
sources.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3680
The debug spew for printing out supported buffer
formats was missing a bunch, among them the fp16
formats that are interesting for HDR support.
Add them.
Note that we still only support ARGB8888. But
at least we can print out what don't support.
This adds a "release" destructor for the gtk_surface1 interface which
signals to the server that a surface has been destroyed on the client
side, which the current "destroy" does not do.
Ideally the protocol would have specified a destroy request marked as
destructor to handle this automatically, however this is no longer
possible due to the destroy method being implicitly generated in the
absence of an explicit request in the protocol. Adding a destroy request
marked as destructor now would generate a new destroy method that
unconditionally would send the request to the server, which would break
clients running on servers not supporting that request.
Commit e6209de962 added some checks on TranslationEntry.valid in
order to figure out whether using the new font settings or the
old g-s-d ones. However that's only set in the non-sandboxed case.
This makes sandboxed applications fallback to the old (and also
non-existing with modern g-s-d) settings, possibly resulting in
ugly defaults being picked.
Fix this by also marking TranslationEntry elements as valid when
using the settings portal, precisely those entries that we are able
to read and match with our own table.
