DESCRIPTION

       Tk_HandleEvent  is  a  lower-level  procedure  that  deals  with  window  events.   It   is   called   by
       Tcl_ServiceEvent  (and  indirectly  by  Tcl_DoOneEvent),  and  in  a few other cases within Tk.  It makes
       callbacks to any window event handlers (created by calls to Tk_CreateEventHandler)  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.
