Question

I’m looking for a push in the right direction. I have a simple chat program, written totally in Java, and am looking for a way to get the Taskbar icons to flash. Preferably in a manner similar to Pidgin, or MSN.

I’m hoping for a platform independent solution, as there are both Linux and Windows users, and preferably totally in Java.

There is unfortunately no way to do this in the standard Swing API. But you could work around it in several ways:

• Flash the icon and title of the window (set a timer and change them whenever it fires).
• Request focus, then immediately make the window invisible; reverse the process at your preferred interval.

Both techniques are demonstrated in this forums.sun.com thread.

Alternatively, instead of flashing, you could display a message in the system tray using TrayIcon.displayMessage(); that may or may not suit you better, but beware that it may not work cross-platform.
