用Java實現程序最小化到托盤區

我在程序中實測必須是16*16的圖片才行

下面的這個程序簡單地實現了把java應用程序縮小到托盤的方法.

程序運行的jdk要是1.6才行,因為這是J2SDK1.6新加的一些類和方法.

import java.awt.*;
import java.io.*;
import javax.swing.*;
import java.awt.event.*;
import javax.imageio.ImageIO;

public class Test extends JFrame{
private TrayIcon trayIcon;//托盤圖標
private SystemTray systemTray;//系統托盤

public Test()
{
super("系統托盤圖標");
systemTray = SystemTray.getSystemTray();//獲得系統托盤的實例
setSize(150,150);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setVisible(true);
try {
trayIcon = new TrayIcon(ImageIO.read(new File("0.gif")));
systemTray.add(trayIcon);//設置托盤的圖標，0.gif與該類文件同一目錄
}
catch (IOException e1) {e1.printStackTrace();}
catch (AWTException e2) {e2.printStackTrace();}

this.addWindowListener(
new WindowAdapter(){
public void windowIconified(WindowEvent e){
dispose();//窗口最小化時dispose該窗口
}
});

trayIcon.addMouseListener(
new MouseAdapter(){
public void mouseClicked(MouseEvent e){
if(e.getClickCount() == 2)//雙擊托盤窗口再現
setExtendedState(Frame.NORMAL);
setVisible(true);
}
});
}

public static void main(String args[])
{
new Test();
}
}
