From libinput documentation:
Also optional is a feature called "drag lock". With drag lock disabled,
lifting the finger will stop any drag process. When enabled, libinput
will ignore a finger up event during a drag process, provided the finger
is set down again within a implementation-specific timeout.
From libinput documentation:
A tap immediately followed by a finger down and that finger being held
down emulates a button press. Moving the finger around can thus drag
the selected item on the screen.
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

The capability tablet tool is new in Libinput 1.2. As build.kde.org
does not yet support this version, it's only an optional check.
So far the code only detects whether the capability exists and reports
this accordingly.
This test mocks part of KWin::Udev, udev and libinput. The test itself
is still rather limited and only verifies whether libinput is valid or
not and that assignSeat works. Most of the interaction is not yet tested,
though to a large degree doesn't make sense and should be rather tested
in the context of LibInput::Connection.
This new test includes everything used in events.cpp to the mocked
functionality of libinput. Only key event is implemented so far, the
referenced pointer and touch functions are mocked with default values.
The test verifies that a KeyEvent gets created and the key press/release
works as expected.
Summary:
The usage of libinput is completely mocked. The test covers all the
constant properties read by Device.
There are some features which are not yet tested:
* alphaNumericKeyboard
* supportedButtons
* enabled
The setters for leftHanded and pointerAcceleration are also covered
including the variants where it can fail.
