把rcp最小化到系统托盘

1. 在WorkbenchWindowAdvisor实现类中初始化trayitem

public void postWindowOpen() ...{
        initStatusLine();
        final IWorkbenchWindow window = getWindowConfigurer().getWindow();
        trayItem = initTaskItem(window);
        if (trayItem != null) ...{
            hookPopupMenu(window);
            hookMinimize(window);
        }

}

//初始化trayitem
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 = Activator.getImageDescriptor(IImageKeys.ONLINE)
                .createImage();
        trayItem.setImage(trayImage);
        trayItem.setToolTipText("test");
        return trayItem;
}

//初始化trayItem上的context menu
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);
            }
        });
}
//自定义minimize到系统托盘和恢复的行为
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);
                }
            }
        });
}

2. fillTrayItem可以写在ActionBarAdvisor的实现类中

protected void fillTrayItem(IMenuManager trayItem) ...{
     trayItem.add(aboutAction);
     trayItem.add(exitAction);
}
