The new API is temporary. It's needed to help us with porting plasma to
the layer shell protocol until Qt 6.6 is released, which includes
QWaylandShellSurface::attachPopup().
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.
If the property is set, the compositor will try to put the window on the
given output. If not set, the compositer will decide where to put the
window (usually the active output). The motivation for this change is the
ability for KRunner to always appear on the active output.
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.
