 .TH Tk_QueueWindowEvent 3 7.5 Tk "Tk Library Procedures"
 .BS
 .SH NAME
 Tk_CollapseMotionEvents, Tk_QueueWindowEvent \- Add a window event to the Tcl event queue
 .SH SYNOPSIS
 .nf
 \fB#include <tk.h>\fR
 .sp
 int
 \fBTk_CollapseMotionEvents\fR(\fIdisplay, collapse\fR)
 .sp
 \fBTk_QueueWindowEvent\fR(\fIeventPtr, position\fR)
 .SH ARGUMENTS
 .AS Tcl_QueuePosition position
 .AP Display *display  in
 Display for which to control motion event collapsing.
 .AP int collapse in
 Indicates whether motion events should be collapsed or not.
 .AP XEvent *eventPtr  in
 An event to add to the event queue.
 .AP Tcl_QueuePosition position in
 Where to add the new event in the queue:  \fBTCL_QUEUE_TAIL\fR,
 \fBTCL_QUEUE_HEAD\fR, or \fBTCL_QUEUE_MARK\fR.
 .BE

 .SH DESCRIPTION
 .PP
 \fBTk_QueueWindowEvent\fR 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 \fBTcl_QueueEvent\fR to add the event
 to the queue.  When the event is eventually removed from the queue it is
 processed just like all window events.
 .PP
 When multiple motion events are received for the same window in rapid
 succession, they are collapsed by default.  This behavior can be controlled
 with \fBTk_CollapseMotionEvents\fR.  \fBTk_CollapseMotionEvents\fR always
 returns the previous value for collapse behavior on the \fIdisplay\fR.
 .PP
 The \fIposition\fR argument to \fBTk_QueueWindowEvent\fR has
 the same significance as for \fBTcl_QueueEvent\fR;  see the
 documentation for \fBTcl_QueueEvent\fR for details.
