XmUpdateDisplay(3X)
OSF/Motif
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 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.

  widget
      Specifies any widget or gadget.
