Tk_QueueWindowEvent(3) Tk Library Procedures Tk_QueueWindowEvent(3)
Tk_CollapseMotionEvents, Tk_QueueWindowEvent - Add a window event to
the Tcl event queue
Display *display (in) Display for which to control
motion event collapsing.
int collapse (in) Indicates whether motion
events should be collapsed or
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,
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.
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
callback, clock, handler, modal timeout, events
