XmUpdateDisplay(3X) X11 SDE 5.4R3.00 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.
