Enter grabs are checked for in CheckMotion(), each time the sprite window changes the current grab is deactivated (if applicable) and the new grab is activated (if applicable). Exception - if the grab is on a parent window of the current window since we keep the grab across descendants. Since CheckMotion() may change the grab status of a device, we mustn't get "dev->deviceGrab.grab" in ProcessOtherEvents until after CheckMotion(). FocusIn grabs are checked in much the same manner. The event delivery for grabs replaces the NotifyNormal on window change with a NotifyGrab on window change. Note that this happens before the grab activates, so the EnterNotify(NotifyGrab) is still delivered to the window, not to the grabbing client. This is in line with the core protocol semantics for NotifyGrab events. Signed-off-by: Peter Hutterer <peter.hutterer@who-t.net>
