Summary:
In order to add more tabs which can further help monitoring how KWin
handles some aspects the DebugConsole is changed to not take keyboard
input. This means it can only be navigated using pointer device or touch
screen.
This is needed for adding a new tab to monitor clipboard changes. On
Wayland sometimes windows don't get the clipboard, so it would be
helpful to have a debug monitor to see when the clipboard changes. But
for that debug console window may not take keyboard events.
To support this DebugConsole sets the WA_ShowWithoutActivating attribute
which gets honored by the InternalWindowEventFilter and does not forward
key events to such windows.

Summary:
The Effect class is extended by three new virtual methods:
* touchDown
* touchMotion
* touchUp
The methods return a boolean value so that the events can be filtered
out. E.g. an effect which has also a mouse grab installed wants to
filter out all events, other effects don't need the events exclusively.
This is a difference to how e.g. keyboard and pointer events are handled.
But is more close to how KWin's internal input event passing works and
makes it easier to get touch event: one does not explicitly has to grab
the events. It's also closer to Wayland where all input events are
available.
As a first example the Present Windows effect is adjusted and allows to
activate windows through the touch screen. As much code as possible is
shared with pointer input.

Summary:
So far when KWin intercepted a key event a leave was not sent to the
Wayland surface currently having keyboard focus. This could result in
the Wayland application to start repeating keys. E.g.
1. application gets key press event
2. This triggers an internal window to show
3. key release goes to KWin internal window
4. application starts to repeat key as there is no release
With this change whenever KWin intercepts the key event e.g. due to
* internal window
* Effects grabbing key event
* Tabbox
the focused keyboard surface is set to null, thus triggering a leave
event and the client not starting to repeat the event.

Summary:
Restores feature parity with X11. Global shortcuts need to trigger
also for repeat events. An example is the volume key or screen
brightness.
For other shortcuts like showing yakuake it does not make sense to
trigger on repeat. Thus a long term solution is to add a flag to
global shortcuts whether the key should trigger on repeat.

Summary:
Gesture events are swipe or pinch events on a touch pad.
This change implements basic support by:
* wrapping them in LibInput::Event
* processing them in LibInput::Connection and emitting
dedicated signals
* Forwarding them in InputRedirection to PointerInputRedirection
* Support them in the internal input event filter
* Printing debug information in DebugConsole
Further handling is not yet done. In future the following should be
implemented:
* activating e.g. zoom and present windows on pinch/swipe gesture
* forwarding non global gestures to KWayland
Note that forwarding to KWayland is not yet useful as QtWayland does
not yet have support for the unstable protocol. No Qt application could
make use of it yet. So for the moment just global gestures is the best
we can get.
Test Plan: Looked at output of DebugConsole when triggering gestures

Summary:
This is a workaround for QTBUG-54371 resulting in QtWayland never
requesting the input methods panel without having keyboard focus.
Thus also the virtual keyboard is not working.
With this change we go back to always announcing a keyboard and
binding the virtual keyboard to whether we don't have an alpha-numeric
keyboard instead of whether there is a keyboard on the seat.

Summary:
So far when a ShellClient got unmapped ready_for_painting was set to
false. That is the ShellClient was treated in the same way as a not
yet shown window. It was completely excluded from painting, a close
animation impossible.
This change makes use of the functionality available in
Client::hiddenInternal(). The window is considered as hidden, thus
still excluded from e.g. getting input events, but could be rendered
any time as we still have a previous window pixmap (if referenced).
This allows to have it considered in the rendering pass, but effects
still cannot make use of it as that state is not yet exposed to the
effects.

The id we internally have is a signed int and might be negative, but
the touch id we get is unsigned. We can savely cast the unsigned to
signed as touch ids are recycled and more than 10 touch points is
unlikely to be useful.
Summary:
The signals emitted by LibInput::Connection carry the Device for which
the input event was received. This Device is passed to the input handlers.
Custom event classes are added which extend QMouseEvent, QKeyEvent and
QWheelEvent respectively and expose the Device. The Device is only passed
around as a forward declared pointer, so even if compiled without libinput
support, it should still compile.
Event handlers which need to get access to the Device can now just cast
the event pointer to the custom class and access it. This can be used in
future to handle device specific key codes, etc.
As we don't have a proper event classes for touch events the event
handlers do not yet have access to the Device. Here the internal API
needs to be adjusted in future.

Summary:
Qt's touch event API is rather difficult and complex to implement.
As none of KWin's internal windows supports multi-touch gestures yet,
this is going the easy route and just simulates a left mouse button
press. If in future need arises for touch gesture support on KWin's
internal windows, this can be added.

Touch events are emulating mouse events, in particular left mouse
button.
With this change one can move windows through the decoration, use
the decoration buttons and also support the double click action.
As finding the decoration is pretty much exactly the same as for
pointer events, a new base class is introduces which provides the
functionality of updating the decoration and the shared common

Summary:
Mouse actions like wheel and double click were restricted to the titleBar
area. This made the top most pixel non-interactive as it's not part of the
titleBarArea.
This change makes the complete titlebarPosition interactive. That is it
includes for a "normal" (top) setup also the TopLeft/Top/Right section.
Thus the top most pixel can be double clicked, mouse wheeled, etc.
For the Wayland case the test case is adjusted.

The configuration file kcminput, group Mouse is parsed to decide whether
pointer devices should be in left handed mode. The config is applied
whenever a new device is added.
In addition the Connection listens to KGlobalSettings for a mouse
settings changed signal which might be emitted by the mouse KCM.
When such a signal is emitted, all pointer devices are reconfigured.
This allows to change the mouse handed settings on Wayland.

All the important information like whether we are on the active vt are
also provided by Logind. So instead of integrating with VirtualTerminal,
which integrates with Logind, we can just integrate with Logind directly.
On special request by sebas. It's not really dangerous as by default
the xkb layout doesn't have it enabled. So if a user actually enables
it, we can also support it.
And now I'm going to reconfigure my layout again to not hit it by chance.

We want TabBox to operate on key press, not on key release. So far
it only operated on release as the press was filtered out by the
global shortcuts filter. To prevent that the tab box filter is moved
before the global shortcuts filter.
Note: first usage of TabBox has current window selected instead of
next. This problem is also visible on 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.
Drag'n'Drop on Wayland allows us to improve the drag'n'drop experience.
When entering a window during the drag'n'drop operation, KWin raises it.

When starting effect mouse interception the current focused window
and or decoration should get a leave event. Similar when the effect mouse
interception ends the current pointer position needs to be evaluated and
a pointer enter be sent if needed.
So far updating the cursor image was not really defined. It was possible
to use the cursor image from the wayland seat or have a custom set cursor
image. But there are no rules in place to decide which one to use when.
With this change a dedicated CursorImage class is introduced which tracks
the cursor image changes on the seat, on the decoration, in the effects
and so on. In addition it tracks which is the current source for the
image, that is whether e.g. the cursor from the seat or from effects
override should be used. Whenever the cursor image changes a signal is
emitted, which is connected to the signal in AbstractBackend.
Based on that the backends can directly show the image. The existing
code in the backends to install a cursor shape or to install the cursor
from the server is completely dropped. For the backend it's irrelevant
from where the image comes from.
A new feature added is that the cursor image is marked as rendered. This
is then passed on to the frame rendered in the Surface and thus animated
cursors are finally working. Unfortunately animated cursors are broken in
Qt (see https://bugreports.qt.io/browse/QTBUG-48181 ).
Small regression: the command didn't get updated at all, so it was always
MouseNothing.
To prevent such a regression to sneak in again the change comes with
autotest for the action on inactive and active window.
As a Wayland server KWin does not have to emit additional key repeat
events (unlike X11). The clients are responsible for handling this based
on the provided key repeat information.
Internally KWin needs key repeat, though. E.g. the effects need key
repeat (filtering in Present Windows), window moving by keyboard needs
repeat, etc. etc.
This change introduces the internal key repeat. For each key press a
QTimer is started which gets canceled again on the key release. If the
timer fires it invoked processKey with a new KeyboardKeyAutoRepeat state.
This is handled just like a KeyPress, but states are not updated and
the QKeyEvent has autorepeat set to true.
The event filters check for the autorepeat state and filter the event
out if they are not interested in it. E.g. the filters passing the event
to the Wayland client need to filter it out.
Currently auto-repeat is bound to using libinput. This needs to be
modified. The only backend sending repeated events is X11, thus for
other backends it should be enabled.
Whether creating a timer on each key event is a good idea is something to
evaluate in future.

Experimental testing in real world showed it's just a signing issue
in this specific case. The events passed to wayland clients scroll
in correct direction.
With that all the actions are implemented just like on X11.
There are two not yet implemented differences:
* hide splash window when clicking it
* replay event on special window
Implemented in the ForwardEventFilter: before forwarding the event
to the window we check whether a modifier is pressed and perform the
wheel command.
Possible improvements: each axis event triggers the same change, there
is no adjusted scaling.
This change implements the mouse command for modifier (alt/meta) plus
click in InputRedirection so that it also works on Wayland.
Modifier plus mouse wheel is not implemented yet.
For easier code in Options a new method is added which provides the
configured modifier as a Qt::KeyboardModifier instead of a Qt::Key code.
Test case is added which simulates all variants of modifiers plus
supported mouse buttons to trigger move.
So far the key handler in the InternalWindowEventFilter used the
PointerInputRedirection's internal window. This had the result that
key events were only delivered to an internal window if the window
was under the cursor.
This change tries sending the event to the latest created and visible
window. Thus e.g. with nested context menus it goes to the current
sub menu as expected. The return value of sendEvent is used to filter
out the event.
So far the DrmOutput connected to all input events when going into
power saving. As we now have the input filters it's better to just
install a filter when an output goes into powersave and remove the
input filter again when all outputs are enabled again.
To make this work InputRedirection gains a new method to add a new
filter as the first filter. This is a potentially dangerous method
as it allows to have a filter before LockScreenFilter gets the
events. But in case of DPMS it's something we actually want.
A nice new feature possible with the input filter is that we can
filter out the event which re-enables the outputs. Thus when getting
on a system with output off and screen locked, the first key hit
doesn't go to the lock screen.

BUG: 341201
Fixed-in: 5.6.0 (Wayland-only)
Similar to the change regarding pointer and touch a
KeyboardInputRedirection is created. The Xkb class is also moved to
the new files keyboard_input.h and keyboard_input.cpp.
Just like in the case of PointerInputRedirection no signals are added,
but the existing signals in InputRedirection are directly invoked.
All pointer related code is moved into a new class called
PointerInputRedirection.
The main idea is to simplify the code and make it easier to maintain.
Therefore also a few changes in the setup were performed:
* before init() is called, no processing is performed
* init() is only called on Wayland and after Workspace is created
* init property is set to false once Workspace or WaylandServer is
destroyed
Thus code can operate on the following assumptions:
* Workspace is valid
* WaylandServer is valid
* ScreenLocker integration is used
The various checks whether there is a waylandServer() and whether
there is a seat are no longer needed.
Some of the checks have been reordered to be faster in the most common
use case of using libinput. E.g. whether warping is supported is first
evaluated by the variable bound to whether we have libinput and only if
that is false the backend is checked.
The new class doesn't have signals but invokes the signals provided
by InputRedirection. I didn't want to add new signals as I consider
them as not needed. The areas in KWin needing those signals should
be ported to InputEventFilters.
So far the area based edges connected directly to global pointer pos
changed in InputRedirection. This didn't allow proper checking whether
the edge was triggered (e.g. missing timestamp).
This change merges the functionality into the new input filter mechanism.
There is now a dedicated input filter for screen edges, installed after
lock screen and before effects. It always passes events on, but also passes
all events through ScreenEdges to handle the activation. As it's installed
after the lock screen filter we don't need to check for screen locked any
more.
The code is now similar strucutured to the existing X11 based variants
and maybe will allow to also merge the X11 variant with the new one.
The logic should not be tied to whether libinput is used. It's relevant
for all Wayland backends whether they use libinput or not.
In addition this should generate a pointer motion event, so that proper
processing can take place and we get proper pointer enter events.
If the pointer is warped the position change should be treated like
a change coming from the input device. Our normal processing should
take place.
A problem in this case is the timestamp to pass to the wayland server.
Normally our timestamps come from the backend/libinput and we don't
know the next one. As an intermediate solution we just use the last
timestamp on the seat. In future a solution could be to not use the
backend's timestamp at all, but have our own timestamp handling.
