Summary:
KWin used to do a quirky trick to send key events to the topmost QQuickItem
rather than things going to the activeFocus item.
Sending it to the window previously would have failed as the window
didn't think it was active.
Since 66986d4afd we can just let the
window process the events in a normal QtQuick manner.

Summary:
Pointer constraints should become disabled when the TabBox is invoked. Since
the current client stays activated while TabBox is enabled and currently can
not be deactivated with the risk of regression as discussed in D13758, disable
all pointer constraining explicitly and enable it again when the TabBox is
closed.

When I'm explicitly cycling through the windows of an application it makes no sense to show the "global" desktop window.
BUG: 378662
FIXED-IN: 5.12.0
Differential Revision: https://phabricator.kde.org/D9661
Summary:
Commit 5d9027b110 introduced a regression in TabBox by using the generic
framework inside KWin to test for same application. What I did not
consider was that the code in TabBox was "broken by design". It didn't
use the generic check as that is too strict and considers windows from
different processes as not belonging to the same application. But this
is not wanted in the case of TabBox.
On the other hand the change itself is an improvement to also support
Wayland in a better way and not have special handling situations. Thus
just reverting would not help.
Instead this change addresses the problem by extending the internal API
and to allow more adjustements. So far there was already an
"active_hack" boolean flag. This is extended to proper flags with an
additional flag to allow cross application checks.
The checks in Client which would filter out different applications check
for this flag and are skipped if set. In addition ShellClient also adds
support for this flag and compares for the desktop file name.
Thus we get in TabBox the same behavior as before with the advantage of
having a better shared code base working on both X11 and Wayland.

FIXED-IN: 5.11.4
Test Plan:
Started two kwrite processes on X11, clicked new in one of them,
used Alt+` and verified that there are three windows shown.

Summary:
If an Effect has replaced the TabBox and wants to react on mouse events
the EffectsHandlerImpl also has an X11Filter, so we only need to make
sure the events go to that filter.
Motion: TabBox did not filter out, so events will go to the Effects
filter.
Press/Release: TabBox should not operate if Effects take the events.
The events are filtered out by Effects if there is a grab, so just
check for that and go out. Effects will take care.
Test Plan: Compiles

Summary:
Creating the X11Filter directly on startup caused a regression as the
filter got too early in the chain and stole events from the
XInputIntegrationFilter. We don't need the filter all the time, but only
when we have established the TabBox grab. Likewise we can destroy the
filter again when releasing the TabBox grab. So it's much more
encapsulated now.

Summary:
TabBox implemented a custom way to check whether two windows belong to
the same application. KWin internally has API for that which does it
better, in a standardized way and even across windowing system.
This change uses the internal API, resulting in the check working better
on X11 and starts to work on Wayland.

Summary:
A few areas in TabBox perform casts from Toplevel to Client. By casting
to Client instead of AbstractClient the Wayland windows are excluded.
This change addresses the problem by changing the casts where possible.
The only remaining cast to Client is for shading which is not (yet)
supported for Wayland windows anyway.

Summary:
Based on the feedback from discussion on plasma-devel the currently only
default touch action on a screen edge should be window switching. Given
that our default window switcher is located on the left and works very
nicely for touch event it becomes the default action on the left screen.

Summary:
There is a special mode in TabBox which is the noModifierGrab mode. This
is Alt+Tab active without a modifier being hold. This mode is entered
when being activated through screen edges (either pointer or touch). So
far this was not exposed to QtQuick and thus one could not end the mode
using pointer or touch. It is possible to select another window, but not
to activate it. That required the press of a keyboard key.
This setup is rather unfortunate. By exposing the mode to QtQuick we can
react from QtQuick side to it and invoke already exposed functionality to
select and item and directly activate it - existing left-over from the
Plasma Active window switcher.
Test Plan:
Tested on X11 and Wayland with an adjusted lnf package. It kind
of works, but there are additional issues on both X11 and Wayland.

BUG: 333511
Summary:
Prior to this change various event filters performed deep calls into
Xkb class to figure out the modifiers relevant for global shortcuts (aka
consumed modifiers). This shows that this is a general useful
information which should be available to all input event filters
directly.
Thus it's now added to the input events and exposed directly in
InputRedirection so that the calls into Xkb are no longer needed.

Summary:
The TabBox performs the scrolling of the items by itself in order to
support wheel events even if the mouse is not on the TabBox. For that
KWin grabs pointer events on X11 (on Wayland an input filter is used)
and forwards them to the TabBox.
Qt uses Xinput2 for scrolling on the QQuickWindow. Due to that KWin
does not get any xcb core button press/release events when scrolling
inside the QQuickWindow and thus scrolling doesn't work.
There are three possible approaches to fix this:
1. Implement scrolling support in each of the QML switchers
2. Add an xinput2 filter to TabBox
3. Intercept the QWheelEvents on the QQuickWindow
The first approach has the disadvantage that all themes need
adjustment and that there might be behaviorial difference whether one
scrolls on the TabBox window or outside the window.
The second approach would be most in line with the other filters, but
is difficult due to the nature of xinput2 (no xcb bindings, etc).
Thus the third approach might be the best solution. Wheel events are
only delivered to the QQuickWindow if the native events were not already
intercepted, thus we know it won't have side effects for the case that
Wayland is used or xinput2 is not supported.
The implementation installs an event filter on the QQuickWindow which
gets created when showing the TabBox and inside the filter waits till
there is an angleDelta of +/-120 and scrolls by one per every 120 angle
delta as described in the QWheelEvent documentation.

Summary:
The interaction is changed to trigger the check for release from the
TabBoxInputFilter instead of reacting on modifier changes. That way
it's possible to check for the relevant modifiers getting released
instead of getting all modifiers in. Also this means that the checks
are only performed when relevant.

Summary:
So far TabBox used highlight windows by passing window ids around through
an X property. This doesn't work on Wayland where we don't have window
ids for our TabBox and the Wayland windows.
This change introduces a new Effect::Feature for HighlightWindows which
the HighlightWindowsEffect provides. The EffectsHandlerImpl has a new
method to highlightWindows which it delegates to that effect if it is
loaded by invoking a new performFeature method.
The TabBoxHandler now passes the highlighting to the effects system
instead of updating the x11 property. Thus this works on Wayland and
at the same time improves the X11 side by no longer having to go through
the property protocol.
Test Plan: Verified that Alt+Tab highlights the windows on Wayland correctly.

Summary:
Toplevel::window() is the actual X11 window. This makes it difficult
to use as the generic identifier for both X11 and Wayland. The Wayland
ShellClient already had a windowId() which is now added to Toplevel as
a virtual method. On X11 (Toplevel default) it returns the window().
The method window() now returns XCB_WINDOW_NONE for classes without
the Toplevel::m_client, such as ShellClient. Thus it allows to properly
check whether we are on Wayland or X11.
The code is adjusted to use windowId where a generic id is needed and
to properly check whether the window is valid before using it where
a window() is used.
This also fixes at least one additional unknown issue in
Workspace::setActiveClient
where the windowId of a Wayland client was passed to X11.

The TabBox implements methods for those events and performs same
logic as on X11. Click outside of TabBox closes. If the event is on
the TabBox we don't filter the event out and let the internal filter
forward the event.
By using QWindow we can also find the TabBox window on Wayland where
the winId is not really helpful.
This also changes the elevation from Unamanged to Toplevel, so that
it is no longer X11 specific.
Result: TabBox stays on top of all windows also on Wayland.
-use qstringliteral only when necessary (i.e. not in concat or comparison)
-use qbytearray instead of qstring when dealing with latin1 input and output (glplatform)
-use qstringref to extract numbers from strings (glplatform)

-anidata: use ctor init lists, add windowType member initialization
