- This command is used to bring the entire application world
- ``up to date.'' It flushes all pending output to the
- display, waits for the server to process that output and
- return errors or events, handles all pending events of any
- sort (including when-idle handlers), and repeats this set of
- operations until there are no pending events, no pending
- when-idle handlers, no pending output to the server, and no
- operations still outstanding at the server.
-
- If the iiiiddddlllleeeettttaaaasssskkkkssss keyword is specified as an argument to the |
- command, then no new events or errors are processed; only |
- when-idle idlers are invoked. This causes operations that |
- are normally deferred, such as display updates and window |
- layout calculations, to be performed immediately. |
-
- The uuuuppppddddaaaatttteeee iiiiddddlllleeeettttaaaasssskkkkssss command is useful in scripts where |
- changes have been made to the application's state and you |
- want those changes to appear on the display immediately, |
- rather than waiting for the script to complete. The uuuuppppddddaaaatttteeee |
- 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 user interactions; if you |
- occasionally call uuuuppppddddaaaatttteeee then user input will be processed |
- during the next call to uuuuppppddddaaaatttteeee.
