NAME

       XmUpdateDisplay  —  A  function  that  processes  all  pending exposure events immediately
       "XmUpdateDisplay"

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
       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 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 XmUpdateDisplay 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.
