[dep, 13Jun2006] Instead of determining if the system tray is supported, isTraySupported() derives its result from the name of the window manager. Specifically, it returns true only if the window manager is named "Metacity" or "KWin". Not only is there no requirement that the window manager be the entity providing the system tray, at least in the case of Metacity, it really doesn't. This means: If I use Gnome (complete with panel, which supplies the system tray) but with an alternate window manager, SystemTray.isSupported() returns false and I can't use the system tray. If I use Metacity in an environment where there is no system tray (e.g. outside of Gnome), SystemTray.isSupported() will incorrectly return true. More generally, if I have a fully functional system tray but am not running one of the above window managers, I can't access it. This test should be based on the presence of a tray which follows the System Tray Protocol Specification, not random other factors.
