Java鼠标监听器

1.按钮监听事件

 JPanel jp =(JPanel) getContentPane();
 
jp.setLayout(new FlowLayout());
 
JButton jb = new JButton("点我");
 
jp.add(jb);
 
jb.addActionListener(new ActionListener() {

@Override
public void actionPerformed(ActionEvent e) {

System.out.println("点了");
}
});

2.MouseMotionListener

private void into() {
JPanel jp =(JPanel) getContentPane();
 
jp.setLayout(new FlowLayout());
 
JButton jb = new JButton("点我");
 
jp.add(jb);
 
jb.addActionListener(new ActionListener() {

@Override
public void actionPerformed(ActionEvent e) {

System.out.println("点了");
}
});
 
jp.addMouseMotionListener(new MouseMotionListener() {

@Override
public void mouseMoved(MouseEvent e) {
System.out.println("鼠标拖拽了"+e.getPoint());

}

@Override
public void mouseDragged(MouseEvent e) {
System.out.println("鼠标移动了"+e.getPoint());

}
});

3. MouseListener

public class F_Test3 implements MouseListener{


@Override
public void mouseClicked(MouseEvent e) {
System.out.println("鼠标点击了"+e.getPoint());

}


@Override
public void mouseEntered(MouseEvent e) {
System.out.println("鼠标进去了"+e.getPoint());

}


@Override
public void mouseExited(MouseEvent e) {
System.out.println("鼠标退出了"+e.getPoint());

}


@Override
public void mousePressed(MouseEvent e) {
System.out.println("鼠标按下了"+e.getPoint());

}


@Override
public void mouseReleased(MouseEvent e) {
System.out.println("鼠标释放了"+e.getPoint());

}

  在测试类中调用

F_Test6 f6 = new F_Test6();

jt.addKeyListener(f6);

}
