     NAME
          XtBuildEventMask - retrieve a widget's event mask

     SYNTAX
          EventMask XtBuildEventMask(w)
                Widget w;

     ARGUMENTS
          w         Specifies the widget.

     DESCRIPTION
          The XtBuildEventMask function returns the event mask
          representing the logical OR of all event masks for event
          handlers registered on the widget with XtAddEventHandler and
          all event translations, including accelerators, installed on
          the widget.  This is the same event mask stored into the
          XSetWindowAttributes structure by XtRealizeWidget and sent
          to the server when event handlers and translations are
          installed or removed on the realized widget.
