When no qml items manage the arrow key event, the root item will manage it looking to give focus to a view in the given direction derived from the arrow key
BUG:455783
Right now we update QtQuick views after a composition has rendered so
that we'll have them ready for our next frame.
One of my machines (With X11 + nvidia) was quite stuttery, profiling
shows we spend a huge amount of time with the CPU blocked waiting for
the vblank from the previous main compositing to finish swapping before
we could start processing the QtQuick rendering. Time when the CPU is
blocked is wasted time.
This patch does mean kwin's compositing cycle lasts longer but a recent
patch changes the rendering policy when we start a fullscreen effect anyway so
hopefully that should still give us enough time to render that first frame in time.
Since the screen number is well-known, we can look up the default
screen on demand. Note that xcb_get_setup() is pretty cheap as it
simply returns a const pointer to pre-allocated data.
Use SurfaceInterface::inputSurfaceAt when deciding which surface are we
entering when sending a pointer event from a touch, in case it falls
onto a subsurface.

This allows us to unify the X and Wayland codepaths that currently go
through window-system specific IPC. It also allows us to easily track
who called "setShowingDesktop" and cancel the effect when that client
disappears.

This is most likely just an oversight/omission from the times when the
component was actively developed. There are five states total, including
one for realtime interactions; four others need to be transitioned to.
Due to nondeterministic nature of signal propagation in QML, changing
both targetScale and state depending on dragHandler's activity could
result in targetScale wrongly updating before the state change(and thus
applied property changes and subsequent animated transition).
This fixes a bug when a window dragged to the top (but not onto another
desktop) would animate its position back to its original position on a
heap, but the scale would remain constant until the end of animation
and only then rapidly jump back to a normally scaled state.
Quad generation needs a valid surface pixmap. This did not surface
before as the pixmap was only accessed when looping the region which
typically was empty without a pixmap.

This uses the previous pixmap if the current one is invalid,
which ensures the generated quads have sane coordinates.

While at it, move `size` out of the loop as it doesn't change.

If both compositor and applications were to use these gestures at the same
time, that would be quite confusing for the user. This also works around
a bug in Wine that makes applications crash.

This breaks cyclic dependency between Compositor and DRM backend, there
are still indirect dependencies though. However, fewer cyclic
dependencies should make the architecture more cleaner and easier to
tweak.
Otherwise this WindowHeap type is not usable without custom delegate.
/usr/lib/qml/org/kde/kwin/private/effects/WindowHeap.qml:111:23:
QML Component: Cannot create delegate
/usr/lib/qml/org/kde/kwin/private/effects/WindowHeapDelegate.qml:21:5:
Required property windowHeap was not initialized
Switches to a shared pointer rather than a raw one. It would leak, which
in general is not a big problem but it would flood the output when
running tests with ASAN. Also it's the right thing to do.
The wayland backend changes the dpms mode when the enabled state of the
output changes. This creates problems when destroying all outputs on
shut down. The wayland backend calls InputRedirection's methods, but
InputRedirection is already destroyed by that time.
While the crash can be fixed by guarding input() in createDpmsFilter()
with an if statement, changing dpms mode in updateEnablement() doesn't
seem like a good idea because Output changes unrelated states (enabled !=
dpms mode), so let's get rid of it.
This targetOpacity is nowhere to be found. This is a relic of past
development. Currently code that needs to alter opacity based on drag
state does so externally by setting opacity on a delegate as a whole.
On wayland the code to keep windows on the current activity whilst the
window was broken was completely broken in porting. We only held the
block for the duration of the method even though the popup remained open
for longer.
On X11, when removing the window from the current activity it would not
update correctly and remain visible. The code path was as follows:
- the menu is shown an event loop is started
- we change the activities
- as we close the menu focus changes and workspace calls
UserActionsMenu::close this unsets m_window
- We then never call the blockActivityUpdates(false) at the end of
UserActionsMenu::show
This patch addresses both at once.
We get rid of the nested event loop as that was always evil. This means
slotWindowOperation no longer needs to be queued.
We perform cleanup of m_window and the activity blocker when the menu
closes which should be safer.
BUG: 456873
At the moment, a platform should provide two output lists - one that
lists all available outputs, and the other one that contains only
enabled outputs. In general, this amounts to some boilerplate code and
forces backends to be implemented in some certain way, which sometimes
is inconvenient, e.g. if an output is disabled or enabled, it will be
simpler if we only change Output::isEnabled(), otherwise we need to
start accounting for corner cases such as the order in which
Output::isEnabled() and Platform::enabledOutputs() are changed, etc.
This can be used to make our backends more multi-purpose. At the moment,
new outputs are enabled by default, but it makes sense to do otherwise.
For example, if an output is disabled by default, it would be possible
to delegate initial output configuration to layer above, to kwin.
In long term, the drm backend would need to scan connectors, create an
Output for every one of them, kwin sees new outputs and tries to apply
the initial output configuration, which includes the enabled status.
Since we don't have any means of getting notified by _NET_WM when a
windowType changes, and since KWin would handle that quite poorly, AND
since no one does that in real-world applications anyway, we might as
well mark those getters as CONSTANT, so that QML engine would stop
complaining about depending on non-NOTIFYable properties.
According to the specification, the window type should be decided before
a window gets mapped.
In X11 when a window is maximised if the client is unable to fufill the
space provided we centre align the window.
With the new floating point geometry behaviour of centreing changes.
Instead of a 1 pixel gap at the top, we get a 0.5 pixel gap either side.
When we get into the codepath to "fix" the window in `closeHeight` we
only move the top, giving us an invalid buffer size.
We don't really want to change the logic here; on xwayland with the
scaling opt-out path it's feasible for a floating sized logical size to
still be representable. This code rounds to the native unit after all
the logic has taken effect.
