DESCRIPTION
       Tk_HandleEvent is a lower-level procedure that deals with window events.  It is  called  by  Tcl_Ser-viceEvent Tcl_ServiceEvent
       viceEvent (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.
