The tray icon implementation in Java 1.6 has its limitations, e.g. no support for the alpha channel in the graphic icons. Did anybody tried to use SWT to support a native looking tray icon? Is that possible at all?
OK, I gave it a try: it works fine on Windows but on Linux it crashes as soon as I close a JFrame or JDialog. It looks like SWT gets confused by the AWT windows on its Linux implementation.
