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.
