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

SYNOPSIS
       void XmUpdateDisplay (widget)
	       Widget  widget;
       (void)

DESCRIPTION
       XmUpdateDisplay	provides  the  application with a mechanism for forcing all pending exposure events to be removed from the input queue and
       processed immediately.  When a user selects a button within a menu pane, the menu panes are unposted and then any activation callbacks reg-
       istered	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 menu panes 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 XmUpdateDis-
       play before starting its time-consuming operation.  This function is also useful any time a transient window, such  as  a  dialog  box,	is
       unposted; callbacks are invoked before normal exposure processing can occur.

       widget	 Specifies any widget or gadget.
