Apps such as Gamescope eventually want to offer a DRM lease option to use planes and handle all of getting to the screen themselves.
This implements logic to allow leasing of desktop displays
Use wlr_output_test() instead of output_ensure_buffer() which is not a
public function and only compiled when linking statically to wlroots.
Also wlr_output_rollback() on failed test.
Fixes issue #273
This allows popups to be rendered above views and other layers. Without
this, the popups of a layer-shell application in the bottom layer would
render below views, which does not seem right. For example, consider the
case of a panel with right-click popups.
Add the 'cycleViewPreview.core' option to rc.xml to enable previews of
the selected view when cycling between windows. Default this option to
be disabled to match current behavior.
labwc currently doesn't handle output layout changes very well:
- Windows can end up "lost" completely offscreen
- Maximized/fullscreen windows can end up spanning multiple outputs
Currently, new_output_notify() and output_destroy_notify() contain logic
to update the cursor and force a repaint when outputs are added or
removed. This logic in fact needs to run on any output layout change,
so consolidate it into a new function, output_update_for_layout_change().
Then add a second new function, view_adjust_for_layout_change(), which
adjusts window placement to account for the new layout.
The behavior is roughly as follows:
- Normal windows that end up offscreen are centered on the closest
output (making use of the existing view_center() logic)
- Maximized windows are re-maximized on the closest output. Logic is
also added to the unmaximize step to check that the original
unmaximized position is still on-screen.
- Fullscreen windows are re-fullscreened on the same output if
possible; otherwise they are un-fullscreened.
Minimized windows don't require any special handling. Their placement
is adjusted just the same, but invisible to the user until they are
later unminimized.
There is some positioning glitch still with un-fullscreening a window
whose output has been disconnected/disabled; it can end up in an
unexpected position (but at least has the correct size and decoration).
I don't think this is due to a bug in my change per se, but perhaps the
change has exposed a bug elsewhere.
Fixes: #177
When an output is added or removed, the position of the other
outputs can also change, resulting in windows moving between them.
We need to redraw all the outputs (not just the new one) to prevent
stale/corrupted screen contents.
