Tk_CollapseMotionEvents, Tk_QueueWindowEvent - Add a window event to the Tcl event queue
Tk_QueueWindowEvent places a window event on Tcl's internal event
queue for eventual servicing. It creates a Tcl_Event structure, copies the
event into that structure, and calls Tcl_QueueEvent to add the event
to the queue. When the event is eventually removed from the queue it is
processed just like all window events.
- Display *display (in)
Display for which to control motion event collapsing.
- int collapse (in)
Indicates whether motion events should be collapsed or not.
- XEvent *eventPtr (in)
An event to add to the event queue. It is important
that all unused fields of the structure be set to zero.
- Tcl_QueuePosition position (in)
Where to add the new event in the queue: TCL_QUEUE_TAIL,
TCL_QUEUE_HEAD, or TCL_QUEUE_MARK.
When multiple motion events are received for the same window in rapid
succession, they are collapsed by default. This behavior can be controlled
with Tk_CollapseMotionEvents. Tk_CollapseMotionEvents always
returns the previous value for collapse behavior on the display.
The position argument to Tk_QueueWindowEvent has
the same significance as for Tcl_QueueEvent; see the
documentation for Tcl_QueueEvent for details.
