XmUpdateDisplay(3X) UNIX System V XmUpdateDisplay(3X)
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 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 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.
widget Specifies any widget or gadget.
