Most operating systems have the concept of a tray as a set of icons visible from the main window, which can provide quick access components. On OS X, these are represented as icons across the top menu bar; on Windows, as icons on the bottom-right near the clock. Linux systems have various approaches which do similar, and some operating systems have none. Since there is only one Tray, it is necessary to add the item only once. The Activator class can be used to ensure that TrayItem is created at startup and removed at shutdown.
Open the
Activatorclass and add two private fields:private TrayItem trayItem; private Image image;
Add the following to the
start()method:final Display display = Display.getDefault(); display.asyncExec(new Runnable() { public void run() { image = new Image(display, Activator.class .getResourceAsStream("/icons/sample.gif")); Tray tray = display.getSystemTray(); if (tray != null && image != null)...
