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
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.
