____________________________________________________________________________________________________________

NAME
       Tk_CollapseMotionEvents, Tk_QueueWindowEvent - Add a window event to the Tcl event queue

SYNOPSIS
       #include <tk.h>

       int
       Tk_CollapseMotionEvents(display, collapse)

       Tk_QueueWindowEvent(eventPtr, position)

ARGUMENTS
       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.

DESCRIPTION
       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 details.
