用Java创建NSStatusItem / Menubar应用程序

我正在尝试用Java模拟Objective C的NSStatusItemfunction。 也就是说，我正在尝试编写一个Java应用程序，它将放在Mac的菜单栏中， 就像这样 。 这是 Apple在StatusBar上的文档链接 。

用Java做任何事吗？

使用java.awt.SystemTray 。 我已经确认它适用于OS X Lion。 根据这个问题 ，也可以使用SWT。

例：

import java.awt.AWTException; import java.awt.Image; import java.awt.MenuItem; import java.awt.PopupMenu; import java.awt.SystemTray; import java.awt.Toolkit; import java.awt.TrayIcon; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.net.MalformedURLException; import java.net.URL; public class MenuBarIconTest { public static void main(String[] args) throws MalformedURLException { TrayIcon trayIcon = null; if (SystemTray.isSupported()) { // get the SystemTray instance SystemTray tray = SystemTray.getSystemTray(); // load an image Image image = Toolkit.getDefaultToolkit().getImage(new URL("http://sofzh.miximages.com/java/forum_16.png")); // create a action listener to listen for default action executed on the tray icon ActionListener listener = new ActionListener() { public void actionPerformed(ActionEvent e) { System.out.println("action"); // execute default action of the application // ... } }; // create a popup menu PopupMenu popup = new PopupMenu(); // create menu item for the default action MenuItem defaultItem = new MenuItem("Do the action"); defaultItem.addActionListener(listener); popup.add(defaultItem); /// ... add other items // construct a TrayIcon trayIcon = new TrayIcon(image, "Tray Demo", popup); // set the TrayIcon properties trayIcon.addActionListener(listener); // ... // add the tray image try { tray.add(trayIcon); } catch (AWTException e) { System.err.println(e); } // ... } else { // disable tray option in your application or // perform other actions //... } // ... // some time later // the application state has changed - update the image if (trayIcon != null) { //trayIcon.setImage(updatedImage); } } }
