SYNOPSIS

       EventMask XtBuildEventMask(w)
	       Widget w;

ARGUMENTS

       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.

Name
  XtBuildEventMask - retrieve a widget's event mask.

Synopsis
  EventMask XtBuildEventMask(w)
	 Widget w;

Inputs
  w	    Specifies the widget.  Must be of class Core or any subclass thereof.

Returns
  An event mask with a bit set for each event type the widget is receiving.

Description
  XtBuildEventMask() returns a widget's event mask.  The mask reflects the events the widget is currently selecting.  (If the widget is unre-
  alized, then the mask reflects the events the widget will select when it is realized.)  This event mask is the  logical  OR  of  all	event
  masks selected by adding event handlers and event translations (including accelerators).  It is updated whenever event handlers or transla-
  tions are installed or removed for the specified widget.

Structures
  The event_mask is formed by combining the event mask symbols listed in the table below using the bitwise OR operator ( ).  Each mask symbol
  sets a bit in the event_mask.
