NAME    [Toc]    [Back]

       XmUpdateDisplay  -  A  function that processes all pending
       exposure events immediately

SYNOPSIS    [Toc]    [Back]

       void XmUpdateDisplay (widget)
               Widget widget;

DESCRIPTION    [Toc]    [Back]

       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  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; callbacks  are  invoked
       before  normal  exposure  processing can occur.  Specifies
       any widget or gadget.
