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.
