15af09c70a Introduce Toplevel::frameGeometryChanged signal
Summary:
Currently we have two signals that are emitted when the Toplevel's geometry
changes - geometryShapeChanged() and geometryChanged(). The former signal
is used primarily to invalidate cached window quads and the latter is
sort of emitted when the frame geometry changes. But it's not that easy. We
have a bunch of connects that link those signals together...

The worst part about all of this is that the window quads cache gets
invalidated every time a geometry update occurs, for example when user
moves a window around on the screen.

This change introduces a new signal and deprecates the existing geometryChanged
signal. frameGeometryChanged is similar to geometryChanged except that it is
emitted when an _actual_ geometry change has occurred.

We do still emit geometryShapeChanged signal. However, in long term, we
need to get rid of this signal or come up with something that makes sense
and doesn't require us to waste computational resources.

12886cf442 Be consistent about touch point id type: use qint32
Summary:
There is no point in using quint32 and casting back and forth in numerous places.
Fix a bunch of compiler warnings that we implicitly cast between signed and unsigned.
This makes things consistent with what we get from libinput.

dd55a59d81 Leave decoration on touch up only once
With 05ca6c97f8 removing all touch points always induces
an at surface change to null. But the decoration leave event
is already sent in the decoration input filter. Do not send
it again in the cleanup function.

This makes the decoration input test pass again.

Reviewed by David Edmundson as part of review of 05ca6c97f8.

05ca6c97f8 Unset touch targets on no current touch points
Summary:
Certain input devices like touch screens can be in a state of having no input
target at all. In case of touch screens when there are no current touch points.

In this case unset and block at-surface targets until a touch point is
available again.

Test Plan: Auto test window-selection passes again.

a23368d638 Add Wayland touch drag and drop support
Summary:
Use the new functionality in KWayland to support drag and drop via touch
screens.

Either a drag and drop session with pointer or touch is possible, but not
both at the same time. Pointer/touch gets deactivated if a touch/pointer
drag and drop session is active.

Test Plan: Manually.

2e29711323 Rework InputDeviceHandler focus tracking
Summary:
This patch aims at improving the Toplevel, internal window and decoration
focus tracking.

In detail the goals are:
* Clean tracking of beneath and focus Toplevel as well as decoration and
internal windows. Splitting this up in well defined sub routines.
* Minimal find Toplevel operations on window stack.
* Reduce code duplication in pointer and touch child classes.
* Reuse tracking in drag operations.
* Allow direct usage of Wayland input interfaces for decoration and internal
windows in the future.
* Update touch focus on external events like VD switches correctly.

Test Plan: Manually and existing autotests.

eab71a8a19 Privatize variables in InputDeviceHandler
Summary:
Some members were declared protected. Better style is to have them private
with public or protected getters and setters.

This also removes the unnecessary m_input variable.

7e89c51823 Add workaround for touch input offset for decorated windows
Summary:
If a Wayland window is decorated the decoration size was not considered
when passing touch points to the Wayland window. For pointer input this
is considered and implemented through the input transformation matrix
which KWayland::Server::SeatInterface accepts. This should also be done
for Touch. Unfortunately the frameworks version for Plasma 5.9 is already
tagged and done and we cannot depend on new API.

Thus this change tries to workaround by calculating the proper offset
through the input transformation matrix. It isn't nice but fixes the
problem for now.

BUG: 374778

Test Plan: Only in unit test, real test still missing

84e3308149 Introduce an InputEventSpy for processing input events
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.

e3d79cdda6 Reduce code duplication for processing input events
Summary:
For every input event we have similar code. We go through all
InputFilters, invoke a method with some arguments and check whether
the filter returns true.

Instead of duplicating that logic everywhere, there is now one method
in InputRedirection which takes a std::function to call on the input
filters. The std::function is supposed to be generated with a std::bind
on the InputFilter::method with all the required arguments.

69cbb40903 Pass LibInput::Device* through the event handlers
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.

ff88f93852 Support touch events on KWin internal windows
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.

Test Plan: Tested on exopc with DebugConsole and auto test

73fae5e63d Support touch events in DecorationEventFilter
Summary:
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
variables.

f8f8e61466 Make integration with KScreenLocker optional in WaylandServer
Summary:
In order to start the WaylandServer in kwin_x11 we need to make sure
that WaylandServer does not start the KScreenLocker integration. On
X11 the lock screen is provided by a different application (in Plasma
by ksmserver).

A new init flag is added to WaylandServer to not integrate with
KScreenLocker. Thus the default is still to integrate with KScreenLocker.

All direct usages of KScreenLocker are guarded to not be called if
the screenlocker integration is not present.
