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 regis-
tered 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.
