NAME
       XmUpdateDisplay - A function that processes all pending exposure events
       immediately

SYNOPSIS
       void XmUpdateDisplay (widget)	  Widget    widget;

DESCRIPTION
       XmUpdateDisplay provides the application with a mechanism  for  forcing
       all pending exposure events to be removed from the input queue and pro‐
       cessed immediately.  When a user selects a button  within  a  MenuPane,
       the MenuPanes are unposted and then any activation callbacks registered
       by the application are invoked.	If one of  the	callbacks  performs  a
       time-consuming  action,	the portion of the application window that was
       covered by the MenuPanes will not have been  redrawn;  normal  exposure
       processing does not occur until all of the callbacks have been invoked.
       If the application writer  suspects that a callback will	 take  a  long
       time,  then  the	 callback  may choose to invoke XmUpdateDisplay before
       starting its time-consuming operation.  This function  is  also	useful
       any  time  a transient window, such as a dialog box, is unposted; call‐
       backs are invoked before normal exposure processing can occur.	Speci‐
       fies any widget or gadget.
