Question

获取鼠标状态（按下，在窗口里的坐标，经过，是否在窗口）

Answer 1

import java.awt.BorderLayout;
import java.awt.Frame;
import java.awt.Label;
import java.awt.TextField;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import java.awt.event.MouseMotionListener;

public class TwoListener implements MouseMotionListener, MouseListener
{
private Frame frame;

private TextField textField;

public void go()
{
frame = new Frame("Two Lisreners Example");

frame.add(new Label("click"), BorderLayout.NORTH);

textField = new TextField(30);

frame.add(textField, BorderLayout.SOUTH);

frame.addMouseMotionListener(this);
frame.addMouseListener(this);
frame.addMouseListener(new MyMouseListener());

frame.setSize(300, 200);

frame.setVisible(true);
}

public static void main(String[] args)
{
TwoListener listener = new TwoListener();

listener.go();
}

@Override
public void mouseClicked(MouseEvent e)
{
// TODO Auto-generated method stub

}

@Override
public void mousePressed(MouseEvent e)
{
// TODO Auto-generated method stub

}

@Override
public void mouseReleased(MouseEvent e)
{
// TODO Auto-generated method stub

}

@Override
public void mouseEntered(MouseEvent e)
{
// TODO Auto-generated method stub

}

@Override
public void mouseExited(MouseEvent e)
{
String str = "The mouse has left the Frame";

this.textField.setText(str);
}

@Override
public void mouseDragged(MouseEvent e)
{
String str = "x:" + e.getX() + ",y:" + e.getY();

this.textField.setText(str);
}

@Override
public void mouseMoved(MouseEvent e)
{
// TODO Auto-generated method stub

}
}

class MyMouseListener implements MouseListener
{

@Override
public void mouseClicked(MouseEvent e)
{
// TODO Auto-generated method stub

}

@Override
public void mousePressed(MouseEvent e)
{
// TODO Auto-generated method stub

}

@Override
public void mouseReleased(MouseEvent e)
{
// TODO Auto-generated method stub

}

@Override
public void mouseEntered(MouseEvent e)
{
String str = "The mouse has entered the Frame";

System.out.println(str);
}

@Override
public void mouseExited(MouseEvent e)
{
String str = "The mouse has exited the Frame";

System.out.println(str);
}
}
以上就可以解决你的要求了哈，希望对你有帮助哈。

这个跟英文没关系的，自己下个java jdk的api找下相应的类和方法就能了解我的代码了啊。
