Re: Programmatic access to the notification area (aka the System Tray)



That's interesting, as I am not even able to get the WebStart TrayIcon demo to run. But I'm running it with Java 1.5 on Mac OS X 10.4.10.

Note that the WebStart demo hasn't really been properly debugged on the Mac so it's probably a bit flakey for certain things. I've always got a reflection invocation error when I try to run it from WebStart.

But, the code for Mac TrayIcon should work fine if you download it and run it from your desktop. Also, maybe someone tweaked the WebStart demo to work (mostly) on Mac with Java 6 and that is why you are able to run it and I am not.

What exception does the TrayIcon demo throw?

I get the following stack trace in the Java console as soon as I click "Run" in the Java Webstart dialog. However, after posting my previous message I noticed that the tray icon shows up, despite the exception in the Java Console, and seems to run normally. When I select any of the items in the tray icon menu, I see a log message in the Java console that teh event fired. Here's Java Console error dump.

BTW, I'm using the demo found here: http://javadesktop.org/jdic/ demo/TrayIcon/trayicon.jnlp
