java程序系统托盘的托盘图标的展示

java程序系统托盘的托盘图标的显示
刚刚学习java，看到程序右下角图标的显示感觉很新鲜，于是上网查找一些资料。自己写了一个简单的程序实现了一下。

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 javax.swing.JFrame;public class MySystemTray extends JFrame{public MySystemTray() {init();}public void init() {this.setSize(300, 200);this.setLocationRelativeTo(null);this.setTray();this.setVisible(true);}//添加托盘显示：1.先判断当前平台是否支持托盘显示public void setTray() {if(SystemTray.isSupported()){//判断当前平台是否支持托盘功能//创建托盘实例SystemTray tray = SystemTray.getSystemTray();//创建托盘图标：1.显示图标Image 2.停留提示text 3.弹出菜单popupMenu 4.创建托盘图标实例//1.创建Image图像Image image = Toolkit.getDefaultToolkit().getImage("trayIconImage/clientIcon.jpg");//2.停留提示textString text = "MySystemTray";//3.弹出菜单popupMenuPopupMenu popMenu = new PopupMenu();MenuItem itmOpen = new MenuItem("打开");itmOpen.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent e) {Show();}});MenuItem itmHide = new MenuItem("隐藏");itmHide.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent e) {UnVisible();}});MenuItem itmExit = new MenuItem("退出");itmExit.addActionListener(new ActionListener(){public void actionPerformed(ActionEvent e) {Exit();}});popMenu.add(itmOpen);popMenu.add(itmHide);popMenu.add(itmExit);//创建托盘图标TrayIcon trayIcon = new TrayIcon(image,text,popMenu);//将托盘图标加到托盘上try {tray.add(trayIcon);} catch (AWTException e1) {e1.printStackTrace();}}}//内部类中不能直接调用外部类（this不能指向）public void UnVisible() {this.setVisible(false);}public void Show() {this.setVisible(true);}public void Exit() {System.exit(0);}public static void main(String[] args) {new MySystemTray();}}
