| /** |
| * A <code>TrayIcon</code> object represents a tray icon that can be |
| * added to the {@link SystemTray system tray}. A |
| * <code>TrayIcon</code> can have a tooltip (text), an image, a popup |
| * menu, and a set of listeners associated with it. |
| * |
| * <p>A <code>TrayIcon</code> can generate various {@link MouseEvent |
| * MouseEvents} and supports adding corresponding listeners to receive |
| * notification of these events. <code>TrayIcon</code> processes some |
| * of the events by itself. For example, by default, when the |
| * right-mouse click is performed on the <code>TrayIcon</code> it |
| * displays the specified popup menu. When the mouse hovers |
| * over the <code>TrayIcon</code> the tooltip is displayed. |
| * |
| * <p><strong>Note:</strong> When the <code>MouseEvent</code> is |
| * dispatched to its registered listeners its <code>component</code> |
| * property will be set to <code>null</code>. (See {@link |
| * java.awt.event.ComponentEvent#getComponent}) The |
| * <code>source</code> property will be set to this |
| * <code>TrayIcon</code>. (See {@link |
| * java.util.EventObject#getSource}) |
| * |
| * <p><b>Note:</b> A well-behaved {@link TrayIcon} implementation |
| * will assign different gestures to showing a popup menu and |
| * selecting a tray icon. |
| * |
| * <p>A <code>TrayIcon</code> can generate an {@link ActionEvent |
| * ActionEvent}. On some platforms, this occurs when the user selects |
| * the tray icon using either the mouse or keyboard. |
| * |
| * <p>If a SecurityManager is installed, the AWTPermission |
| * {@code accessSystemTray} must be granted in order to create |
| * a {@code TrayIcon}. Otherwise the constructor will throw a |
| * SecurityException. |
| * |
| * <p> See the {@link SystemTray} class overview for an example on how |
| * to use the <code>TrayIcon</code> API. |
