SwingWorker: summary of recommendations

martes septiembre 13, 2005 | SwingWorker | Permalink | Comentarios [1]

So as promised I'm posting some sort of summary with the suggestions (idioms?) for working out Swing with SwingWorkers. Some sort of collection of previous postings. After this I'll move to other things. I am thinking of building a NetBeans module too, because that's very interesting to me. So here we go with the collection:

Make your doInBackground() cancellable by either sleeping or by periodically checking inside loops on termination flags.
Try to handle interruptions gracefully. See, for instance, An OnJava article on how to gracefully interrupt JDBC Statements by using "Statement.cancel()".
Inform the user about the progress, and block input meanwhile, if appropriate Informing the user of the progress is extremely easy with SwingWorkers by using the "setProgress" method. The entry shows links on how to block the user input meanwhile, in case of need.
Reuse in any Java app. Since SwingWorker is LGPLed you can reuse it in SWT applications or even in wx4j (wx4j is a wrap around the excellent wxWidgets (aka wxWindows) framework).
Use SwingWorkers to timeout SwingWorkers an easy trick that works seamlessly.
Remove property listeners Property Listeners should remove themselves from the list of property listeners. The entry contains example code on how to do it.
Make your application concurrent contains links on why you should make your application concurrent. That's at least what my gurus say.
Make your application parallel contains links (and excellent experimental data) on why you should make your application as parallel as possible to achieve a performance boost according to Amdahl's Law.

Happy Swinging,
Antonio
