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 reg-
istered 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 XmUpdateDis-
play 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.
