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.
