请大虾再出手相助！

为什么我java.exe命令运行涉及有awt包的java application程序，程序运行后，我想用右上角的叉叉关闭按钮退出程序，但该按钮失效，为什么？

不知道你的jdk的版本是多少，我用jdk2.1.3没有出现你说的问题。

[cchandyou]

我的jdk版本是1.3，以下是我的一段程序：（用1.3版本编译后运行就出问题，请指教）

import java.awt.*;
import java.awt.event.*;

public class TwoListenInner
{
private Frame f;
private TextField tf;

public static void main(String args[]){
TwoListenInner That=new TwoListenInner();

}

public TwoListenInner(){
f=new Frame("Two listeners example");
f.add("North",new Label("Click and drag the mouse"));
tf=new TextField(30);
f.add("South",tf);
f.addMouseMotionListener(new MouseMotionHandler());
f.addMouseListener(new MouseEventHandler());
f.setSize(300,300);
f.setEnabled(true);
f.setVisible(true);
}

public class MouseMotionHandler extends MouseMotionAdapter{
public void mouseDragged(MouseEvent e){
String s="Mouse dragging: X="+e.getX()+"Y="+e.get();
tf.setText(s);
}
}

public class MouseEventHandler extends MouseAdapter{
public void mouseEntered(MouseEvent e){
String s="The mouse entered";
tf.setText(s);
}
public void mouseExited(MouseEvent e){
String s="The mouse has left the building";
tf.setText(s);


}
}
}

加上window监听器试试看 :)
import java.awt.*;
import java.awt.event.*;

public class TwoListenInner
{
private Frame f;
private TextField tf;
public static void main(String args[]){
TwoListenInner That=new TwoListenInner();
}

public TwoListenInner(){

f=new Frame("Two listeners example");
f.add("North",new Label("Click and drag the mouse"));
f.addWindowListener (new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
});

tf=new TextField(30);
f.add("South",tf);
f.addMouseMotionListener(new MouseMotionHandler());
f.addMouseListener(new MouseEventHandler());
f.setSize(300,300);
f.setEnabled(true);
f.setVisible(true);
}
public class MouseMotionHandler extends MouseMotionAdapter{
public void mouseDragged(MouseEvent e){
String s="Mouse dragging: X="+e.getX()+"Y="+e.getY();
tf.setText(s);
}
}

public class MouseEventHandler extends MouseAdapter{
public void mouseEntered(MouseEvent e){
String s="The mouse entered";
tf.setText(s);
}
public void mouseExited(MouseEvent e){
String s="The mouse has left the building";
tf.setText(s);
}
}
}
