The button state was not represented correctly which was very visible
when using the MouseClickEffect. Now MouseClickEffect on Wayland works
as expected.
In kwin_wayland the InputRedirectionCursor is created before the X11
connection is established. Because of that possible usage needs to
be guarded. This is only in cursorTracking so far. The parent class
exposes whether the cursor is tracked and the doStartCursorTracking
gets invoked again when the x11Connection becomes available.
The porting to Qt5 broke the timestamp handling in many areas. A deeper
look into Qt's xcb plugin shows that the appTime handling is not
sufficient for KWin's need. E.g. the time is only updated in response to
a property notify event if it's for a Qt created window, which is hardly
ever the case in KWin. Another example is that key press/release events
never updated the appTime.
As the functionality in Qt is rather trivial we can do the timestamp
handling ourselves. We filter all events anyway and it is slightly faster
as we don't have to go through the QPA interface any more.

Straight forward port from XLib based XCursor library to the
xcb variant which is considerably new. The xcb variant only allows
to create xcb_cursor_t for the default theme and size. Which suits
the needs in Cursor quite well, but means it's not a replacement for
the usage in zoom effect.

So far all cursors were only resolved through Qt::CursorShape, but
Qt::CursorShape is not a complete mapping of all cursors used inside
KWin. E.g. killwindow uses the "pirate" cursor.
This change keeps the cursors by name instead of Qt::CursorShape and
thus allows us to use Cursor for resolving XCursors everywhere.
In a default startup startkde does not set XCURSOR_SIZE environment
variable. Only XCURSOR_THEME is set. The size should be DPI dependent.
With this patch Cursor is able to handle this situation and does not
fall back to loading the config from file. Logic is taken from
KHintsSettings in frameworkintegration which in turn is from
KApplication.

Connecting to the DBus signal emitted on KGlobalAccels by the
cursor kcm and forcing a reload of all cursors. For runtime
config change we need to take the config value and need to ignore
the now outdated environment variables.

BUG: 325763
FIXED-IN: 5.2.0
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!
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.
required until there's a dynamic poll rate, because 10Hz is too
low for magnifiers (lag), mousemark (paints too edgy), mouseclick
(often fails because it's easy to cycle the button state within 100ms)
- and the bouncing icon lags behind the mouse as well ;-)

KWin::Cursor can track changes to the cursor image. It supports a
start/stop tracking to not handle these events if nobody is interested in
them. When enabled and the cursor image changes a signal is emitted with
the serial number of the new cursor image.
To track cursor image changes xcb_xfixes_select_cursor_input is used (see
XFixes Version 5.0 protocol, section 7).
This could be useful for the zoom effect when it replaces the cursor.

The define KWIN_SINGLETON adds to a class definition:
public:
static Foo *create(QObject *parent = 0);
static Foo *self() { return s_self; }
protected:
explicit Foo(QObject *parent = 0);
private:
static Foo *s_self;
There is an additional define KWIN_SINGLETON_VARIABLE to set a different
name than s_self.
The define KWIN_SINGLETON_FACTORY can be used to generate the create
method. It expands to:
Foo *Foo::s_self = 0;
Foo *Foo::create(QObject *parent)
{
Q_ASSERT(!s_self);
s_self = new Foo(parent);
return s_self;
}
In addition there are defines to again set a different variable name and
to create an object of another inheriting class.
All the classes currently using this pattern are adjusted to use these
new defines. In a few places the name was adjusted. E.g. in Compositor
the factory method was called createCompositor instead of create.
REVIEW: 109865
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.
