NAME

7       immediately

SYNOPSIS

10       void XmUpdateDisplay (widget)
11               Widget  widget;

DESCRIPTION

15       XmUpdateDisplay provides the application with a mechanism  for  forcing
16       all pending exposure events to be removed from the input queue and pro‐
17       cessed immediately.  When a user selects a button within a  menu  pane,
18       the  menu  panes  are unposted and then any activation callbacks regis‐
19       tered by the application are invoked. If one of the callbacks  performs
20       a time-consuming action, the portion of the application window that was
21       covered by the menu panes will not have been redrawn;  normal  exposure
22       processing does not occur until all of the callbacks have been invoked.
23       If the application writer suspects that a callback  will  take  a  long
24       time,  then  the  callback  may choose to invoke XmUpdateDisplay before
25       starting its time-consuming operation.  This function  is  also  useful
26       any  time  a transient window, such as a dialog box, is unposted; call‐
27       backs are invoked before normal exposure processing can occur.

29       widget    Specifies any widget or gadget.
