ARGUMENTS

20       Display *display (in)                    Display for which  to  control
21                                                motion event collapsing.
22
23       int collapse (in)                        Indicates    whether    motion
24                                                events should be collapsed  or
25                                                not.
26
27       XEvent *eventPtr (in)                    An  event  to add to the event
28                                                queue. It  is  important  that
29                                                all   unused   fields  of  the
30                                                structure be set to zero.
31
32       Tcl_QueuePosition position (in)          Where to add the new event  in
33                                                the   queue:   TCL_QUEUE_TAIL,
34                                                TCL_QUEUE_HEAD,             or
35                                                TCL_QUEUE_MARK.

DESCRIPTION

39       Tk_QueueWindowEvent places a window event on Tcl's internal event queue
40       for eventual servicing.  It creates a Tcl_Event structure,  copies  the
41       event into that structure, and calls Tcl_QueueEvent to add the event to
42       the queue.  When the event is eventually removed from the queue  it  is
43       processed just like all window events.
44
45       When  multiple  motion events are received for the same window in rapid
46       succession, they are collapsed by default.  This behavior can  be  con‐
47       trolled  with  Tk_CollapseMotionEvents.  Tk_CollapseMotionEvents always
48       returns the previous value for collapse behavior on the display.
49
50       The position argument to Tk_QueueWindowEvent has the same  significance
51       as  for  Tcl_QueueEvent;   see the documentation for Tcl_QueueEvent for
52       details.
