Summary:
So far KWin started to filter out the escape key as soon as it gets
pressed. This was done by unsetting keyboard focus. The idea was to
reset keyboard focus when it is only a short press and that then the
keyboard state is correct for the application. But in practice this
does not work. The only application currently supporting pointer
constraints (Xwayland) does not do anything on a key which is pressed
when gaining keyboard focus. The result is escape not working in
pointer constrained Xwayland windows.
This change addresses this problem by changing the interaction to only
unset keyboard focus when our break constraints condition is met. This
should also result in the application not handling the key release, but
it means it gets the key press. Unfortunately I don't have a good way
to test.

Making QActions with the Connection as a parent is dangerous as it gets

KGlobalAccel and QAction aren't thread safe and we shouldn't be using it

Summary:
During pointer motion we already had the condition that an update of
focused pointer surface can only happen when no button is pressed. But
there are more conditions where we try to update the focused pointer even
if a button is pressed. E.g. if the stacking order changes.
This happens when trying to move one of Qt's dock widgets:
1. Press inside a dock widget
2. Qt opens another window, which is underneath the cursor
3. KWin sends pointer leave to parent window
4. dock widget movement breaks
This change ensures that also this sequence works as expected and the
pointer gets only updated when there are no buttons pressed, no matter
from where we go into the update code path.

Summary:
So far KWin did not properly handle popup windows. That is when a popup
surface got created and a click outside the surface happened KWin did not
send out the popupDone Wayland event.
This change makes KWin aware of whether a surface is a popup and tracks
through a new PopupInputFilter whether there are popup windows. In case
there are popups the new filter waits for mouse press events and cancels
the popups if the press does not happen on any surface belonging to the
same client. To quote the relevant section of the Wayland documentation:
The popup grab continues until the window is destroyed or a mouse
button is pressed in any other client's window. A click in any of the
client's surfaces is reported as normal, however, clicks in other
clients' surfaces will be discarded and trigger the callback.
So far the support is still incomplete. Not yet implemented are:
* support xdg_shell popup windows
* verifying whether the popup is allowed to be a popup
* cancel the popup on more global interactions like screen lock or
kwin effect

Summary:
Each Edge creates a SwipeGesture for touch activation. The swipe needs to
be a single finger starting from the edge into the screen for at least
20 %. The SwipeGesture and GestureRecognizer is extended to support the
use cases of the touch screen edge swipe.
New features supported by the gesture system are:
* minimum and maximum position
* a minimum delta for the swipe
* progress signal based on the minimum delta
* starting a swipe with a start point
The Edge has the progress signal connected to its approach signal, thus
visual feedback is provided through the screen edge effect.
The screen edge system supports touch only for the edges (corners are
too difficult to activate on touch screens). At the moment the following
features are supported:
* screen edge show/raise of windows (e.g. auto hidden panels)
* trigger the configured action
* trigger the configured callback function (e.g. script)
In future it might make sense to add a touch specific configuration
action to support different actions for screen edges activated by mouse
and touch.

Summary:
This change adds global touchpad swipe gestures to the
GlobalShortcutsManager and hooks up the swipe gestures as defined at the
Plasma Affenfels sprint:
* swipe up: Desktop Grid
* swipe down: Present Windows
* swipe left: previous virtual desktop
* swipe right: next virtual desktop
The main work is handled by two new classes: SwipeGesture and
GestureRecognizer. This is implemented in a way that it can be extended
to also recognize touch screen gestures and pinch gestures.
The SwipeGesture defines what is required for the gesture to trigger.
Currently this includes the minimum and maximum number of fingers
participating in the gesture and the direction. The gesture gets
registered in the GestureRecognizer.
The events for the gesture are fed into the GestureRecognizer. It
evaluates which gestures could trigger and tracks them for every update
of the gesture. In the process of the gesture tracking the
GestureRecognizer emits signals on the Gesture:
* started: when the Gesture gets considered for a sequence
* cancelled: the Gesture no longer matches the sequence
* triggered: the sequence ended and the Gesture still matches
The remaining changes are related to hook up the existing shortcut
framework with the new touchpad gestures. The GlobalShortcutManager
gained support for it, InputRedirection and EffectsHandler offer methods
to register a QAction. VirtualDesktopManager, PresentWindows and
DesktopGrid are adjusted to support the gesture.

Summary:
So far KWin's input event processing is mostly based on
InputEventFilters. A filter can - as the name suggest - filter out an
input event from further processing. Our code shows that this is not
sufficient for all input event processing.
We have several areas inside KWin where we need to have access to all
input events, where the processing needs to happen on all events and
filtering is not allowed. This results in sub-optimal code which has
classes which know too much and do too much.
Examples:
* key-repeat handling done in KeyboardInputRedirection
* Layout change OSD in Xkb
* modifier only shortcuts in Xkb
* emitting signals for Cursor class in KeyboardInputRedirection
Also there are misuses of the InputEventFilters and internal API
* DebugConsole keyboard state (uses wrong information)
* DebugConsole input events tab (uses Filter, should be a spy)
This change introduces the API needed to fix these problems. It
introduces an InputEventSpy which is modelled after the InputEventFilter
with the difference that it has only void messages and uses the KWin
introduced event classes.
The spies are always processed prior to the filters, thus we know it can
have all events.

Summary:
There are two types of constraints supported:
1. Pointer confinement
2. Pointer locking
In the case of confinement the pointer is confined to a given region of
the surface. This is comparable to general operation where the pointer
is confined to the screen region.
In the second case the pointer gets locked. That means it cannot move at
all. No further position updates are provided, only relative motion
events can go to the application. There is a hint about cursor position
update on unlock which is not yet implemented in KWayland::Server, thus
also not in this change.
The implementation in KWin grants the requests for pointer constraints
when the pointer enters the constrained region, either by pointer
movement or by e.g. stacking order changes. There is no confirmation
from user required to enter that mode. But we want to show an OSD when
the pointer gets constrained, this is not yet implemented, though.
Breaking an active constraint is relatively easy. E.g. changing the
stacking order will break the constraint if another surface is under the
cursor. Also (in case of confinement) moving the pointer to an
overlapping window breaks the confinement. But as soon as one moves the
pointer back to the window a constraint might get honoured again.
To properly break there is a dedicated event filter. It listens for a
long press of the Escape key. If hold for 3sec the pointer constraint is
broken and not activated again till the pointer got moved out of the
window. Afterward when moving in the pointer might activate again.
The escape filter ensures that the key press is forwarded to the
application if it's a short press or if another key gets pressed during
the three seconds. If the three seconds way fires, the later escape
release is not sent to the application.
This basic interaction is also ensured through an added auto test.
This change implements T4605.

The screenshot effect provides two new dbus methods to (interactively)

In order to properly support the relative motion events as they are

Summary:
When triggering global shortcuts we are more interested in the hold
keys than the currently active modifiers. E.g. capslock should not
be seen as "shift is hold". Similar we need to remove consumed
modifiers. Shift+5 is % and not Shift+% - the shift modifier is
consumed and needs to be removed from shortcut evaluation.
To support this we need to have the actual state directly from
xkbcommon. Thus a new method is added which exposes the modifiers
relevant for global shortcut matching. In addition on every key press
all consumed modifiers are calculated and kept so that they can be
used for shortcut matching.
In addition a workaround is added for Backtab. Similar workaround
exists in kglobalaccel for X11. The problem is that our shortcuts are
stored incorrectly: Shift+Tab instead of Backtab. Thus a mapping back
is required. To make everything worse KWin registers the wrong key
sequence "Alt+Shift+Backtab" which doesn't make any sense and is
broken on X11 at least.
The workaround supports both special cases. The one for Backtab should
be turned into Shift+Tab and also KWin's special case of adding shift
to backtab.

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.

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

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.

The signals emitted by LibInput::Connection carry the Device for which

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.
