Absolute margin values pose a problem if you want to place a surface
certain distance away from a screen edge (in percents) but you also want
the compositor to place the surface on the active output.
At the moment, this issue is worked around by using kwin dbus api to
query the active output. This is not good.
This change is a take on allowing to specify margin values in fractions.
It can be used to drop a dbus call in krunner and assist us with porting
other components to layer shell, e.g. OSDs, they also need to be placed
one third away the bottom screen edge.
Depending on code path taken, geometry.size() == m_pendingSize can
produce incorrect results.
If a configure event is applied, it's fine.
If the window is resized by user, m_pendingSize will have outdated value,
and setWindowGeometry() can ignore future size updates that are valid.
In hindsight, we need special hooks in the QWaylandWindow to request and
apply new geometry. Rather than have one function that deals with all cases.
This reverts commit be63783888.
It broke keyboard input in sddm greeter. While defaulting to a non-spec
value is not great, it's also not that critical. It might be worth
considering synchronizing Qt::WindowDoesNotAcceptFocus with the keyboard
interactivity flag, but the tricky part is that the keyboard interactivty
is not just a boolean.
BUG: 477251
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().
With QWaylandWindow::setShellIntegration(), it's possible to use
xdg-shell and layer-shell protocols in the same process. It's important
for plasmashell, where we want to use the layer shell protocol for
special surfaces such as the desktop background, and the xdg shell
protocol for dialogs.
In order to make a QWindow use the layer shell protocol, you need to
call LayerShellQt::Window::get() before the window is mapped.
