1.AWT简单例子

TestFrame.java

 1 import java.awt.Button;
 2 import java.awt.Frame;
 3 import java.awt.event.ActionEvent;
 4 import java.awt.event.ActionListener;
 5 import java.awt.event.WindowEvent;
 6 import java.awt.event.WindowListener;
 7 
 8 public class TestFrame extends Frame {
 9     
10     public void launch(){
11         Button b = new Button("按钮");
12         b.addActionListener(new MyActionListener1());
13         b.addActionListener(new MyActionListener2());
14         this.add(b);
15         this.pack();
16         
17         this.addWindowListener(new WindowListener() {
18             
19             @Override
20             public void windowClosing(WindowEvent e) {
21                 System.out.println("windowClosing");
22                 System.exit(0);
23             }
24             
25             @Override
26             public void windowClosed(WindowEvent e) {
27                 System.out.println("windowClosed");
28             }
29 
30             @Override
31             public void windowOpened(WindowEvent e) {
32                 // TODO Auto-generated method stub
33                 
34             }
35 
36             @Override
37             public void windowIconified(WindowEvent e) {
38                 // TODO Auto-generated method stub
39                 
40             }
41 
42             @Override
43             public void windowDeiconified(WindowEvent e) {
44                 // TODO Auto-generated method stub
45                 
46             }
47 
48             @Override
49             public void windowActivated(WindowEvent e) {
50                 // TODO Auto-generated method stub
51                 
52             }
53 
54             @Override
55             public void windowDeactivated(WindowEvent e) {
56                 // TODO Auto-generated method stub
57                 
58             }
59             
60         });
61         
62         this.setVisible(true);
63     }
64      
65     private class MyActionListener1 implements ActionListener {
66 
67         @Override
68         public void actionPerformed(ActionEvent e) {
69             System.out.println("MyActionListener1");            
70         }
71         
72     }
73     
74     private class MyActionListener2 implements ActionListener {
75 
76         @Override
77         public void actionPerformed(ActionEvent e) {
78             System.out.println("MyActionListener2");            
79         }
80         
81     }
82     
83     
84     public static void main(String[] args) {
85         new TestFrame().launch();
86     }
