Without this when krunner expands, the frame after kwin will resize it
back to the last size the layer shell requested to be resized to.
To detect when we should not send an explicit size on window resize
events we check the anchors; if we're constrained on opposing edges we
want the compositor alone to set the size.
QWaylandLayerSurface pulled data from the Window on startup. The Window
pushed data into the QWaylandLayerSurface on changes. Having two
patterns is a sign of something being off.
This moves everything to a single design, pulling from the public
interface. This allows us to drop a code path that meddles with
QWaylandWindow internals.
When a compositor has no outputs listed Qt creates a dummy placeholder
QScreen object that does not represent a wl_output.
This should still be fixed in the clients to not create a view, it's
wasteful and probably will still have plenty of other bugs, hence the
giant warning, but it's still worth guarding.
CCBUG: 439096
In the current implementation we cannot use a LayerShellQt before the
shell surface is created.
At the moment a shell surface is created, the constructor is run and
then QtWayland commits the current state. This means the compositor
configures the window before a client has any chance to set anchors or
margins.
This works whilst we're just being a simple fullscreen window, but won't
scale for plasmashell in the future.
This patch makes LayerShellQt::Window always creatable, and we can set
and cache properties before the platform window is created, just like
one can on QWindow and XDGShell properties.
This also makes it less potentially crashy as ::get always returns a
valid result, and
sets up the public API to be QML-able as an attached property in future.
