Summary:
The idea behind the debugging console is to have a feature comparable
to xprop and xwininfo just for Wayland. We cannot have command line
utils as that violates the security restrictions, thus it needs to be
exposed directly in KWin.
The debugging console is invoked through DBus:
qdbus org.kde.KWin /KWin showDebugConsole
This opens a window with a tree view. The DebugConsoleModel which is
used by the tree view groups all windows into four categories:
* x11 clients (that is Workspace::clientList() and Workspace::desktopList())
* x11 unmanaged (Workspace::unmanagedList())
* wayland shell clients (WaylandServer::clients())
* wayland internal clients (KWin's own QWindows - WaylandServer::internalClients())
Each window is a child to one of the four categories. Each window itself
has all it's QProperties exposed as children.
This allows to properly inspect KWin's internal knowledge for windows and
should make it easier to investigate problems. E.g. what's a window's
geometry, what's it's window type and so on.
The debugging console is intended as a developer tool and not expected to
be used by users. That's why it's invokation is rather hidden. Due to
the fact that it's internal to KWin it results in:
* no window decoration
* stealing keyboard focus
* no way to resize, close, move from KWin side
* rendered above all other windows
There is a dedicated close button to get rid of it again. While the
console is shown it's hardly possible to interact with the system in
a normal way anymore. This is something which might be improved in
future.
At the moment the model is able to update when windows are added/removed,
but not yet when a property changes. Due to the lack of interaction with
the existing system, that's not a high priority at the moment, but can
be added in future.

A transient window should always be visible on the current screen.
This change ensures that a transient is always placed in a way that
the transient window is visible on the screen ignoring the transient
offset hint if it has to be.
Unfortunately QtWayland doesn't set the transient hint correctly:
a sub menu is a transient to the main window and not to the parent
menu resulting in quite off positioned menus, see:
https://bugreports.qt.io/browse/QTBUG-51640
Need to add client pos to the transient's position. The offset is
relative to the parent surface, but the client doesn't know about the
size of the decoration, thus KWin needs to add it.
Test creates windows and transients for it and verifies the position.
For decorated windows the position is currently broken as it does not
consider the adjusted client position.
Try to fix test on CI system. With neither a config nor the env variables
the cursor selection falls back to the default cursor theme, which might
not contain the cursors we need.
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.
The test case verifies that setting an override cursor during mouse
interception works and that it's also possible to change it. When
ending mouse interception the cursor image should be adjusted again.
The test shows that when mouse interception starts KWin should send
a pointer leave event to the current focused window and similar needs
to handle the stop of mouse interception.
Updating the focused pointer surface results in the cursor to change.
The CursorImage needs the current focused window to evaluate which cursor
to use, though. Thus we need to make sure that the window reflects the
current state before updating the seat.
This test case verifies that the cursor image and hot spot changes
correctly when focusing a window, changes when damaged and hides.
Test shows that when focusing a window the cursor image is not
removed, neither that unfocus sets back to fallback cursor properly.
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.
Canceling the animation in the animationEnded handler triggers a crash.
This is due to multiple lists being iterated and manipulated at the same
time.
This adds a test case which simulates the crashy situation.

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.
This makes QCursor::pos and QCursor::setPos function correctly. KWin
actually wouldn't need it as KWin has the KWin::Cursor replacement, but
it allows Qt internal API to have it function correctly and also the
zoom effect does use QCursor::setPos.
The mapping is slightly inspired by the mapping in QtWayland.
But the mapping in QtWayland seems wrong. E.g. there is a linux kernel
button called BTN_BACK which is not mapped to Qt::BackButton.
Anyway we are not really interested in the mapping being 100 % correct
for the case in KWin. KWin internally uses only very few mouse buttons
and all others are only relevant to figure out whether buttons are
pressed. The button code itself is passed to the seat with the native
code.
The MoveResizeWindowTest is extended by a test case to verify that
the move only ends once all mouse buttons are released. So far this
is not yet the case as KWin has an incorrect mapping of buttons to
Qt::MouseButtons.
So far KSldApp was always either in state AcquiringLock or Unlocked
during the tests. Due to a fix in WaylandServer it now can also enter
the Locked state. But this is timing related and also depends on whether
the greeter works at all. E.g. on build.kde.org the greeter fails to
start, so it never enters the Locked state.
The adjusted test now considers that the state might have changed to
Locked and expects one additional signal to be emitted.
CI system is adjusted, so that OpenGL should work. At least latest
run didn't show the EGL warnings in the lock screen test. So let's
try to enable again. It's possible that this fails horribly. If that's
the case I'll revert again.
The dontCrashGlxgearsTest is kept on QPainter as locally it crashes
on teardown (needs fixing).
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.
The test removes the second screen while the cursor is on it. This
should warp the pointer to the center of first screen and trigger
a focus enter event.
As can be seen by the expect failures currently it's bound to libinput
and also doesn't process the event as if it were a pointer event.
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.
When warping a pointer through Cursor::setPos it should be processed
just like any other pointer event. It should generate enter/leave event,
create motion events, etc. This is currently not the case as the test
shows.
A new test case which ensures that when stacking order changes the
pointer focus gets re-evaluated and updated. I was positively surprised
to notice that this already works.
Noticed two other problems while writing the test case:
* warping pointer does not re-evaluate the pointer pos
* deleting a ShellSurface (client) does not destroy the ShellClient (server)
When the screen gets locked any existing sequence gets cancelled
and the focused touch surface gets reset. While screen is locked
touch events are filtered to only go to lock screen or input methods.
Test case is added for touch event during lock screen.

Instead of only making the active client the focused keyboard surface,
the method now also performs the lock screen security restriction.
Also just like udatePointerWindow the method becomes public, so that
it can be used from the LockScreenEventFilter and is connected for
lock state changes. This means as soon as the screen locks the current
focused keyboard surface will get a leave event and get an enter event
once the screen unlocks.
The auto test is adjusted to verify these new conditions.

InputRedirection connects to lockStateChanged to udate the current
pointer window. This way we can ensure that the current pointer
surface gets reset as soon as the screen locks (c.f. the expect
fail in the autotest) and also that it restores to the surface under
the mouse once the screen is unlocked.
The relevant code was not yet lock screen aware and performed an
early exit. Part of the code was fine, e.g. findToplevel is lock
screen aware. So this change adjusts the methods for updating the
internal window and decoration to be lock screen aware, that is they
get reset. With that updatePointerWindow is also lock screen aware.
Thus the LockScreenFilter can also use updatePointerWindow just like
the normal handling and does not need to reimplement parts of it. As
it now relies on other code being correct it has an additional check
to verify that the current pointer surface is a surface which is allowed
to get events. If it isn't the events are not forwarded.

The test creates a QRasterWindow which through KWin's internal QPA
is considered an internal window. In the test methods we simulate
various pointer events (enter/leave, press/release, wheel).
