Replacement class for QCursor With Qt5 QCursor does no longer provide ::handle() which was used to set a cursor on a native XWindow for which we do not have a QWidget. Also KWin has had for quite some time an optimized version to get the cursor position without doing XQueryPointer each time ::pos() is called. These two features are merged into a new class Cursor providing more or less the same API as QCursor. In addition the new class provides a facility to perform mouse polling replacing the implementations in Compositor and ScreenEdges. For more information about the new class see the documentation for the new class in cursor.h.

Integrate KWin::Cursor with InputRedirection New inheriting class which uses the InputRedirection to track the cursor position. It doesn't support warping of cursor. This introduces a slight dependency loop in the startup. Cursor needs to be created after the WaylandBackend to ensure that the operation mode is set correctly. But the WaylandBackend itself is accessing Cursor. It should be safe as inside the WaylandBackend it's only accessed after callbacks.

#include "input.h"
Support modifier only shortcuts on X11 Summary: With this change KWin/X11 reuses Wayland's modifier only shortcut architecture. The XInput2 event filter also listens for * XI_RawKeyPress * XI_RawKeyRelease Those events are also reported if another X11 client grabs keyboard input. Thus KWin gets all key events, just like on Wayland. All key events are then sent through the Xkb class which performs the mapping from key codes to key syms and is able to detect whether the modifier got pressed/released without another key being pressed. This change will require a few follow up changes, which are required also for Wayland: * ignore if another input device got interacted (e.g. mouse press, touch screen, scroll, etc) * use the layout from XServer instead of using our own (needed on Wayland in nested setup) The biggest disadvantage of the change is that it triggers a wake up of KWin on every key event. But as KWin already listens to all pointer events that's not a big difference and normally a key event will wake up the compositor any way.

Replacement class for QCursor With Qt5 QCursor does no longer provide ::handle() which was used to set a cursor on a native XWindow for which we do not have a QWidget. Also KWin has had for quite some time an optimized version to get the cursor position without doing XQueryPointer each time ::pos() is called. These two features are merged into a new class Cursor providing more or less the same API as QCursor. In addition the new class provides a facility to perform mouse polling replacing the implementations in Compositor and ScreenEdges. For more information about the new class see the documentation for the new class in cursor.h.

Integrate KWin::Cursor with InputRedirection New inheriting class which uses the InputRedirection to track the cursor position. It doesn't support warping of cursor. This introduces a slight dependency loop in the startup. Cursor needs to be created after the WaylandBackend to ensure that the operation mode is set correctly. But the WaylandBackend itself is accessing Cursor. It should be safe as inside the WaylandBackend it's only accessed after callbacks.

InputRedirection emits a signal when the modifiers change Used by Cursor to properly emit the mouseChanged signal which for historic reasons includes the keyboard modifiers. Again some fiddling around with the autotests and kcmrules needed to make it compile. This needs improvement!
