/**
|
|
* @file
|
|
* This file describes the model for sending core enter/leave events and
|
|
* focus in/out in the case of multiple pointers/keyboard foci.
|
|
*
|
|
* Since we can't send more than one Enter or Leave/Focus in or out event per
|
|
* window to a core client without confusing it, this is a rather complicated
|
|
* approach.
|
|
*
|
|
* For a full description of the enter/leave model from a window's
|
|
* perspective, see
|
|
* http://lists.freedesktop.org/archives/xorg/2008-August/037606.html
|
|
*
|
|
* For a full description of the focus in/out model from a window's
|
|
* perspective, see
|
|
* https://lists.freedesktop.org/archives/xorg/2008-December/041684.html
|
|
*
|
|
* Additional notes:
|
|
* - The core protocol spec says that "In a LeaveNotify event, if a child of the
|
|
* event window contains the initial position of the pointer, then the child
|
|
* component is set to that child. Otherwise, it is None. For an EnterNotify
|
|
* event, if a child of the event window contains the final pointer position,
|
|
* then the child component is set to that child. Otherwise, it is None."
|
|
*
|
|
* By inference, this means that only NotifyVirtual or NotifyNonlinearVirtual
|
|
* events may have a subwindow set to other than None.
|
|
*
|
|
* - NotifyPointer events may be sent if the focus changes from window A to
|
|
* B. The assumption used in this model is that NotifyPointer events are only
|
|
* sent for the pointer paired with the keyboard that is involved in the focus
|
|
* events. For example, if F(W) changes because of keyboard 2, then
|
|
* NotifyPointer events are only sent for pointer 2.
