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



Hi there.

Actually, I did the Mac OS X implementation of the TrayIcon API.

I didn't implement the showBalloonMessage on the Mac mainly because the Mac doesn't normally have that kind of notification balloon like on Windows. (That's the one where a bubble pops up over an icon in the windows task bar and tells you that you have mail, or a software download is ready to be installed, etc.)

Also, you're just looking at a demo. This particular demo runs on all platforms that JDIC supports, so it has common functionality. The animated Duke is to show you can (if you want) use an animated GIF and get it to animate. You have to provide the GIF though, so you'd want to draw it however appropriate for your application.

As far as what you do with it in a real application, that's up to you. It allows you to put an icon up in the status bar area, and have it respond to a single or double click, and allows you to attach a Swing JMenu as well, and trap selections of menu items, to do with as your application requires.

But, the code for Mac TrayIcon should work fine if you download it and run it from your desktop.

OK, I'm curious and have too much idle time. I downloaded jdic from here...

The Mac version of course.

Trying to run the Tray demo from there I get a "Show Baloon Message" window. Clicking on the obvious OK button gets...

Exception in thread "AWT-EventQueue-0" java.lang.UnsupportedOperationException: Method showBalloonMessage is unsupported under Mac!

...


After this I noticed it does successfully add a little waving Duke animation to the Finder menu bar. I'm ok with that, it's small enough to be unobtrusive so the repeated and repeated waving won't drive you crazy real fast. The yellowish background seems a little out of place considering everything else is a white background.
But given the above it doesn't appear to do too much really useful.


I don't intend to be overly critical here. It appeared that at least the early work on this was done by the java-dev list's own Elliot Hughes. But this version of this demo does not seem to work completely fine.
