RCP工程系统托盘功能

在开发RCP工程过程中，有时候在最小化窗口的时候希望将窗口托管在系统栏。添加代码如下：

在ApplicationWorkbenchWindowAdvisor类中添加下面的代码：

private Image statusImage;
 private TrayItem trayItem;
 private Image trayImage;
 private ApplicationActionBarAdvisor actionBarAdvisor;public void postWindowOpen() {  initStatusLine();  final IWorkbenchWindow window = getWindowConfigurer().getWindow();  trayItem = initTaskItem(window);  if (trayItem != null) {    hookPopupMenu(window);    hookMinimize(window);  }}private void hookMinimize(final IWorkbenchWindow window) {  window.getShell().addShellListener(new ShellAdapter() {    public void shellIconified(ShellEvent e) {      window.getShell().setVisible(false);    }  });  trayItem.addListener(SWT.DefaultSelection, new Listener() {    public void handleEvent(Event event) {      Shell shell = window.getShell();      if (!shell.isVisible()) {        shell.setVisible(true);        window.getShell().setMinimized(false);      }    }  });}private void hookPopupMenu(final IWorkbenchWindow window) {  trayItem.addListener(SWT.MenuDetect, new Listener() {    public void handleEvent(Event event) {      MenuManager trayMenu = new MenuManager();      Menu menu = trayMenu.createContextMenu(window.getShell());      actionBarAdvisor.fillTrayItem(trayMenu);      menu.setVisible(true);    }  });}private TrayItem initTaskItem(IWorkbenchWindow window) {  final Tray tray = window.getShell().getDisplay().getSystemTray();  if (tray == null)    return null;  TrayItem trayItem = new TrayItem(tray, SWT.NONE);  trayImage = AbstractUIPlugin.imageDescriptorFromPlugin(      "org.eclipsercp.hyperbola", IImageKeys.ONLINE).createImage();  trayItem.setImage(trayImage);  trayItem.setToolTipText("Hyperbola");  return trayItem;}public void dispose() {  if (trayImage != null) {    trayImage.dispose();    trayItem.dispose();  }}

在ApplicationActionBarAdvisor中添加下面函数protected void fillTrayItem(IMenuManager trayItem) {  trayItem.add(aboutAction);  trayItem.add(exitAction);}
