 NAME    [Toc]    [Back]
      XmUpdateDisplay - A function that processes all pending exposure
      events immediately

 SYNOPSIS    [Toc]    [Back]
      void XmUpdateDisplay (widget)
              Widget  widget;
      (void)

 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 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.
