In labwc, we have had trouble with XWayland windows using the Globally
Active input model (see wlr_xwayland_icccm_input_model()). Under
traditional X11, these windows do not expect to be given focus directly
by the window manager; rather, the WM sends them a WM_TAKE_FOCUS message
prompting the client to take focus voluntarily.
Currently, these clients are difficult to support with wlroots, because
wlr_xwayland_surface_activate() assumes the client window will always
accept the keyboard focus after being sent WM_TAKE_FOCUS. Some Globally
Active client windows (e.g. panels/toolbars) don't want to be focused.
It's useless at best to focus them, and might even make them misbehave.
Others do need keyboard focus to be functional -- and there doesn't seem
to be any reliable way to know this in advance.
Adding wlr_xwayland_surface_offer_focus() allows the compositor to send
WM_TAKE_FOCUS to a client window supporting it and then see whether the
client accepts or ignores the offer. If it accepts, the surface will emit
the focus_in signal notifying the compositor that it has received focus.
This is entirely opt-in. A compositor that doesn't want to use the new
function can continue to call wlr_xwayland_surface_activate() directly
just as before.
This swaps the argument order of wlr_surface_accepts_touch() and
wlr_surface_accepts_tablet_v2(), putting the wlr_surface argument first
as should be the case for functions namespaced with wlr_surface_*.
This will let compositors know if changing adaptive_sync state has any
chance of working. When false, then the current state is the only
supported state, including if adaptive_sync is currently enabled as is
the case for Wayland and X11 backends.
When true, changing state might succeed, but no guarantee is made. It
just indicates that the backend does not already know it to be
impossible.
This commit fixes the following interaction:
1) The host compositor sends a configure sequence for an output.
2) Before handling it, the guest compositor disables and immediately
re-enables the output.
3) The guest compositor tries to ack the configure event from step 1
which isn't relevant anymore after unmapping and re-initialization.
Instead, ignore all configure events after unmapping until we're sure
the host compositor has processed the unmapping.

- Reset all variables representing an initialized xdg_toplevel's state
on unmap.
- Send an initial commit only when an output is about to be enabled.
- If an output isn't configured yet, don't commit a buffer.
It's cumbersome for compositors to guard every
wlr_color_transform_ref() or wlr_color_transform_unref() call
behind a #if WLR_HAS_COLOR_MANAGEMENT. Moreover, none of the LCMS2
types are used in our public API.
Instead, always install the color.h header, and add a stub for
wlr_color_transform_init_linear_to_icc().
Since wlroots almost always significantly breaks API each minor release,
allowing parallel installation of wlroots helps packagers deal with
programs that require conflicting versions of wlroots.
Closes: #3786
This has been introduced way back in
be297d9d14 but is never used anywhere.
If compositors want to save the old dimensions before reacting to a
fullscreen or maximize event they can just grab the sizes within their
event handlers instead.
This change makes it possible to support both the direct srgb-format
pipeline and indirect (color-managed, or non-srgb-format) pipeline
for the same render buffer.
Instead of having separate getters for shm formats and DMA-BUF
formats, use the same pattern as wlr_output_impl.get_primary_formats
with a single function which takes buffer caps as input.
