DESCRIPTION

       Tk_HandleEvent  is  a  lower-level  procedure  that  deals  with  window  events.   It  is  called  by  Tcl_ServiceEvent (and indirectly by
       Tk_DoOneEvent), and in a few other cases within Tk.  It makes callbacks to any window event handlers (created by  calls	to  Tk_CreateEven-
       tHandler)  that	match  eventPtr and then returns.  In some cases it may be useful for an application to bypass the Tk event queue and call
       Tk_HandleEvent directly instead of calling Tcl_QueueEvent followed by Tcl_ServiceEvent.

       This procedure may be invoked recursively.  For example, it is possible to invoke Tk_HandleEvent  recursively  from  a  handler	called	by
       Tk_HandleEvent.	 This  sort of operation is useful in some modal situations, such as when a notifier has been popped up and an application
       wishes to wait for the user to click a button in the notifier before doing anything else.
