Most display updates are performed as -idle callbacks, so \fBupdate idletasks\fR will cause them to run. -However, there are some kinds of updates that only happen in -response to events, such as those triggered by window size changes; -these updates will not occur in \fBupdate idletasks\fR. -.PP -The \fBupdate\fR command with no options is useful in scripts where -you are performing a long-running computation but you still want -the application to respond to events such as user interactions; if -you occasionally call \fBupdate\fR then user input will be processed -during the next call to \fBupdate\fR. - -.SH KEYWORDS -event, flush, handler, idle, update |
