Libinput is an optional dependency for getting low level input events.
As opening the input devices requires root privs this is rather
pointless in the current state. But there is a small added test app which
can be executed with root privs to demonstrate the functionality. To
properly get input events we need a wrapper like it's used in weston.
So far the following is setup:
* opening devices found by udev
* forwarding keyboard events to InputRedirection
* forwarding pointer button events to InputRedirection
* forwarding pointer axis events to InputRedirection
* signals emitted for pointer motion events
Pointer motion events need some further work as they are provided
as delta events. We need to track that and map them properly.
Also missing are touch events due to me not having a touch screen.
It should be fairly simple to setup the touch events, though.
Also hotplugging of devices is not yet implemented.
It was used to check whether we should create the Wayland interaction,
but now that is in kwin_wayland and kwin_x11 doesn't even try to create
the WaylandBackend.
The idea is to manage the cursor position by ourself. This is needed
when KWin gains libinput support and doesn't rely on the Seat anymore.
The suggestion for this is to use SubSurfaces. The nice side-effect is
that we can do cursor warping again which we need e.g. for ScreenEdge
activation or for the kill helper, etc. Clients on the other side
still cannot (and should not) warp the pointer.
This means the X11CursorTracker is no longer bound to the WaylandSeat.
Instead the WaylandSeat just connects to the signal emitted by the
X11CursorTracker. This allows to use the X11CursorTracker also in cases
where we don't use a Seat for setting the cursor image.
We are interested in going into createSurface exactly once when
everything is ready. This is something we now know due to the new signal
in Registry. So instead of multiple entry points there is just one.
The new test does not cover ScreenEdges completely, so far the
following areas are handled:
* creating of the edges
* reserving of edges
* trigger callback
* cursor pushback
* blocking of edges for fullscreen active clients
The default was set that the grid size for one desktop is (1, 2)
which doesn't make any sense at all - it should be (1, 1).
This most likely only affects the unit test as in production the
default layout is taken fron NETRootInfo.
Move the buffer-swap-pending state from the compositing backends to
the Compositor class. The Compositor is the only class that needs to
access the state, and this way it to do it without calling through
a chain of virtual functions. This commit adds two new functions to
Compositor; aboutToSwapBuffers() and bufferSwapComplete(). The
backends call these functions to set and reset the buffer-swap-pending
state.
This commit also renames a number of functions and variables to make
their meaning clear.
The act of promoting the contents of the back buffer to become the
contents of the front buffer is referred to as posting the buffer,
presenting the buffer, or swapping the buffers; rendering the buffer
is what paintScreen() does.
The wayland protocols need the .c files compiled in gnu90 mode.
All known compilers used for kwin support the -std= flag, so setting it
unconditionally should be fine

This is a very interesting auto test as Screens uses both Workspace
and Client. Thus it operates in the "impossible to mock" area.
The solution is to provide mock includes in autotests and ensure that
when building the auto-test the mock header includes will be picked
first. There is now a mock class for Workspace and Client providing
just the API pieces used inside Screens.
As Screens is abstract and we cannot properly interact with
QDesktopWidget there is also a MockScreens class inheriting from Screens
and mocking the required functionality (by just operating on a list of
QRects).
The auto-test itself is only performing checks on the abstract class.
The mock class is indirectly tested by Screens calling into the virtual
methods. The test case is not yet complete, but looking quite good
already.
