在Eclipse Java中未检测到鼠标输入

我正在制作一个需要用户从鼠标输入的程序，所以我制作了一个鼠标类来扩展MouseAdapter。当通过在窗口中单击来测试它时，它什么也没做。代码如下所示。谢谢你的帮助

主课

public class Main extends JFrame {

    private static final long serialVersionUID = 1L;

    public Main() {
        add(new Window());

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(720, 480);
        setLocationRelativeTo(null);
        setTitle("Mouse Input");
        setVisible(true);
        setResizable(false);
    }

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

}

窗口类

public class Window extends JPanel implements ActionListener {

    private static final long serialVersionUID = 1L;

    public Window() {       
        addMouseMotionListener(new Mouse());

        Timer timer = new Timer(10, this);
        timer.start();

    }

    @Override
    public void actionPerformed(ActionEvent arg0) {

    }

}

老鼠课

class Mouse extends MouseAdapter{

    public void mouseClicked(MouseEvent e) {
        System.out.println("Clicked");
    }

    public void mouseDragged(MouseEvent e) {
        System.out.println("Dragged");
    }

}

它在单击时不起任何作用，因为您已将其作为MouseMotionListener添加到JPanel中，而不是作为MouseListener。您还需要通过

addMouseListener（…）

方法将鼠标实例传递到JPanel中，以便发生MouseListener事件

i、 e

addMouseMotionListener（新鼠标（））； addMouseListener（新MouseListener（）{

我刚刚意识到，它在被拖的时候什么也做不了。

public Window() {
  Mouse myMouse = new Mouse();
  addMouseMotionListener(myMouse); // you already have this
  addMouseListener(myMouse);  // **** add this!! ****

        @Override
        public void mouseReleased(MouseEvent arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void mousePressed(MouseEvent arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void mouseExited(MouseEvent arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void mouseEntered(MouseEvent arg0) {
            // TODO Auto-generated method stub

        }

        @Override
        public void mouseClicked(MouseEvent arg0) {
            System.out.println("asdasd");

        }
    });
