This is more extensible: in the future we can introduce event
structs if we need to.
|
|
Ensures there are no fields with uninitialized memory.
Also remove an outdated TODO: Xwayland only supports a single seat.
|
|
|
|
This only contains the xsurface, which isn't particularly useful.
|
|
|
|
This is a bit more type-safe.

Recently it has come up that someone wants to re-use part of
wlroots in their own project. The standard procedure is to copy
over the license text and copyright lines.
Let's make it clear that the wlroots copyright is held by all
wlroots contributors, and that the license file comes from the
wlroots project.
See [1] for more details.

This function takes a pointer to memory with a hardcoded format
and many parameters to describe the pixel buffer.
wlr_output_cursor_set_buffer() can be used instead.
|
|
Stop using wlr_output_cursor_set_image() because it's getting
dropped. Instead, use wlr_output_cursor_set_buffer().
This mirrors what wlr_output_cursor_set_image() is doing
under-the-hood.
|
|
Superseded by wlr_cursor_set_buffer().
|
|
|
|
A saner replacement for wlr_cursor_set_image():
- Takes a wlr_buffer instead of numerous parameters and a hardcoded
format.
- The scale is not used to filter outputs.
- A ref to the buffer is kept to apply it to new outputs.
|
|
set_image() will go away.
|
|
This now matches the transformations used for e.g. cursor scissor
regions and damage.
|
|
We already compute it during the render list creation, we should cache
it and re-use the value.
|
|
By adding a sent_feedback bool into the list entry that we can mutate
we no longer need to maintain this `sent_direct_scanout_feedback` variable.
sent_feedback will also be useful for output layers.
|
|
We will be able to add more state here
|
|
|
|
When an output is added to wlr_cursor, update its cursor image.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/2119
|
|
Sets the cursor image for each output depending on the wlr_cursor
state.
|
|
Will be useful to apply the current cursor to new outputs.
|
|
Most of the surface-related state does not need to be per-output.
Move it to wlr_cursor_state.
|
|
|
|
Removes one allocation, makes this a bit more consistent with the
rest of wlroots.
|
|
This fixes an issue where the panel_orientation parameter was set but wlroots was ignoring it and
returning OUTPUT_TRANSFORM_NORMAL.

The sway scene port relies on this to create a copy of the buffer for
saved surface purposes.
|
|
|
|
|
|
Leave it up to the compositor to enable new outputs (just like the
DRM backend does).
|
|
|
|
|
|
We have nothing to do when a headless output is enabled/disabled.
|
|
A no-op commit should not schedule a new frame. This aligns the
headless backend with the rest of the backends.
This will be important to handle the enabled → disabled transition.
|
|
|
|
|
|
Removes duplication across all the backends to finally apply the mode
to the output.
|
|
|
|
|
|
Nobody remembers why this is done and it isn't that great if people
use a lot of custom modes.
|
|
If we are only rendering within a region of the surface that is
advertised as opaque, we can choose no blending
|
|
We're using both APIs at the same time.
|
|
wlr_output_update_needs_frame() is called unconditionally at the
end of the function already.
|
|
|
|
This changes the semantics of wlr_output_state. Instead of having
fields with uninitialized memory when missing from the committed
bitflag, all fields are always initialized (and maybe NULL/empty),
just like we do in wlr_surface_state. This reduces the chances of
footguns when reading a field, and removes the need to check for
the committed bitfield everywhere.
A new wlr_output_state_init() function takes care of initializing
the Pixman region.
