XmUpdateDisplay(3) Library Functions Manual XmUpdateDisplay(3) NAME XmUpdateDisplay -- A function that processes all pending exposure events immediately 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 per- forms 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 be- fore starting its time-consuming operation. This function is also use- ful 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.
