Using a QTimer to move the resize/move related code to the end of the
event queue. In case there is another motion event in the queue it will
cancel the timer.
Instead of inspecting the XEvent queue we create a Timer with a
singleshot of 0 msec to move the setActive(false) call to the end of the
event handling. In case there is a matching FocusIn event this will be
handled before the timer fired and can cancel the timer.
the present check can break quick everything depending
on screen snapping settings.
It so far. only worked for quick maximization due to horizontal
"judder" and failed whenever that judder was not possible
(due to screen snapping on left and/or right edge)
BUG: 322852
FIXED-IN: 4.11
REVIEW: 111740
We get the missing send event attribute from anding the event's
response type with 0x80.
This fixes the issue that all open windows got unmapped. The reason for
this was that the existing new Client got reparented to the wrapper which
caused the UnmapNotify event which we used to release the Client and by
that unmapping the window completely.
Focus out handling used to check the event queue for a matching focus in
event to prevent short flickers when no window is active. This is not
possible with XCB and needs a replacement. Maybe a short timer event.
Interestingly the attribute send_event from XUnmapEvent does not exist in
xcb_unmap_notify_event_t and also the X protocol doesn't know anything
about send event.
Button Press/Release do no longer fall through to motion notify as
there is no shared mouse event in xcb. Also the methods in Effects and
TabBox are adjusted to process only button press/release or motion
notify.
ScreenEdges are no longer checked for button press/release. They don't
interact on button press/release so there is no need to check it.
Forwards all xcb events to Workspace::workspaceEvent() which got changed
to process xcb events instead of XEvents. So far all handling is
disabled. Will be re-enabled step by step in the following patches.
Unfortunately the Xcb::Window wrapper cannot be used for the client
window as the client should not be destroyed by KWin.
All the API calls except XSelectInput are changed to xcb and the name is
adjusted to m_client to follow the naming scheme.
The Xcb::Window nicely encapsulates the created wrapper window. As
almost all code is adjusted, the variable is also renamed to
m_wrapper to follow the normal naming scheme.
