/** |
|
* 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. |
