We already have another very similar example which demonstrates
wlr_cursor: "pointer".
|
|
Based on five calls:
wlr_render_timer_create - creates a timer which can be reused across
frames on the same renderer
wlr_renderer_begin_buffer_pass - now takes a timer so that backends can
record when the rendering starts and finishes
wlr_render_timer_get_time - should be called as late as possible so that
queries can make their way back from the GPU
wlr_render_timer_destroy - self-explanatory
The timer is exposed as an opaque `struct wlr_render_timer` so that
backends can store whatever they want in there.
|
|
This example is incomparable with the new rendering API. The old one which
we will drop one day.
|
|
Left out multi-pointer (will be removed) and quads (requires
arbitrary rotation).
|
|
This allows wlroots to support newer versions of the interface
without breaking the API.
|
|
This allows callers to set a destination size different from the
buffer size to scale them.
The DRM backend supports this. The Wayland backend doesn't yet
(we'd need to wire up viewporter).

Fixes the following error:
../examples/dmabuf-capture.c:524:33: error: 'frame_number' is deprecated [-Werror=deprecated-declarations]
524 | ctx->avctx->frame_number, get_fifo_size(&ctx->vid_frames));

This leaves it up to wlr_xcursor_theme_load() to pick the theme
name.
|
|
"left_ptr" is the X11 name, "default" is the cursor spec name.

Up until now, wlr_backend_autocreate() created the wlr_session and
then stuffed it into struct wlr_multi_backend so that compositors
can grab it later.
This is an abuse of wlr_multi_backend and the wlr_backend API:
wlr_backend_get_session() and wlr_multi_backend.session only exist
to accomodate the needs of wlr_backend_autocreate(). What's more,
the DRM and libinput backends don't implement
wlr_backend_impl.get_session.
Instead, return the struct wlr_session to the compositor in the
wlr_backend_autocreate() call. wlr_backend_get_session() will be
removed in the next commit.

This union is unnecessary since the recent input device refactor and can
now be replaced by wlr_*_from_input_device() functions.
|
|
strncpy doesn't guarantee that the result is zero-terminated.
|
|
These functions are too easy to misuse, they don't do bounds
checking.

Now that the DRM backend no longer depends on GBM, we can make it
optional. The GLES2 renderer still depends on it because of our EGL
device selection.
This is useful for compositors with their own renderers, and for
compositors using the Vulkan renderer.

With protocol additions such as [1], compositors currently have no
way to opt out of the version upgrade. The protocol upgrade will
always be backwards-compatible but may require new compositor
features.
The status quo doesn't make it possible to ship a protocol addition
without breaking the wlroots API. This will be an issue for API
stabilization [2].
To address this, let compositors provide a maximum version in the
function creating the global. We need to support all previous versions
of the interface anyways because of older clients.
This mechanism works the same way as Wayland clients passing a version
in wl_global.bind.

The current ARGB2101010 has really "corase" control over the alpha.
Particularily, examples/layer-shell would look really strange with certain
parameters. For examples, when passing an alpha of 0.84, the box would not
appear transparent at all anymore.
Patched as suggested by @mstoeckl -- thank you!

wlr_touch

E.g. With e.g. gnome-terminal we never end up in handle_surrouding
so it will be NULL.
|
|
|
|
This became possible after the usage of wlr_surface_send_frame_done.

The definition of the "drm" dep already calls it.
|
|
These clients don't need wlroots.
|
|
This is a client example, it shouldn't use a compositor library
like wlroots.
|
|
wayland-client isn't really used by wlroots core, so let's move the
dep to where it's needed in the Wayland backend.

This allows us to get damage tracking for free™.

Add RECT nodes to the scene-graph demo to illustrate how they are used.
Here, we add a solid rectangle behind each surface as a quick-and-dirty
border, handling surface.commit in order to size it appropriately.

This reverts commit 9796abccedef881e99d293a2658c4da9466acd88.
This Meson issue has been fixed upstream for a while. We require
0.56.0 so we should never hit an unpatched Meson.
