       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.

       Tcl_QueuePosition   position   (in)      Where  to  add  the  new  event  in  the queue:  TCL_QUEUE_TAIL,

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.
