Uses a setter and clear method pattern rather than having the code
repeated.
Instead of keeping a QPointer, now we are a QObject and we get notified
about destruction intention directly, so we can clear the pointer when
necessary.
Instead of looping through the rects in the region, emit the region at
bulk. It reduces the amount of emissions we do and allows us to pack the
response accordingly.
Instead of putting code in lambda put them in actual slots, this is
right now not useful but when e.g. TextInputV3 is implemented, this way
we can re-use them.
This also simplifies the code little bit and makes it easier to use with
gdb if needed.
subsurfaceTreeChanged is emitted on every damage event. This makes it
very noisy and the model constantly resets. This makes it impossible to
expand the tree (as it resets immediately after).
SubSurfaceMonitor gives us more granular signals whilst handling the
recursive aspect.
Also there are no unmanaged windows that are wayland surfaces, so they
are simplified.
Edge::handle calls showOnScreenEdge, which (on wayland) eventually calls internalShow, which eventually calls ScreenEdges::reserve, which destroys the same edge.
When showScreenOnEdge returns, 'this' has been freed.
Using a singleshot timer allows Edge::handle to return before the Edge is destroyed.
Prefer for() to foreach(), as the latter is deprecated.
Prefer iterating QList using the iteration_expression for() loops,
rather than doing it by index.
Currently, we don't compute the clip region properly for some client-
side decorated applications, for example gedit, due to mixing several
separate coordinate spaces.
This change ensures that the window pixmap shape and the opaque region
are in the same coordinate space - the window pixmap coordinate.
In order to simplify mapping regions from the window pixmap coordinates
to the global screen coordinates, a new helper method was introduced in
the WindowPixmap class - mapToGlobal().
If the Xwayland executable can't be found, the whole session will die
because a criticalError() signal will be emitted.
This change replaces the criticalError() signal with a less severe
signal.
If the errorOccurred() signal has been emitted during the startup
sequence, kwin won't die and will just continue with spawning the
session process.
After splitting out the server part of KWayland into a separate repo,
all non-core protocol wrappers in KWayland::Client had become obsolete
and using them in new projects is highly discouraged.
