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 pro-
cessed immediately. When a user selects a button within a menu pane,
the menu panes 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 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; call-
backs are invoked before normal exposure processing can occur.
widget Specifies any widget or gadget.
