java - 单击 JLabel 运行方法

Question

我想要的只是在单击 JLabel 后运行我的代码，但由于某种原因它不起作用，我无法弄清楚为什么> IDE 或控制台中没有错误。

final JLabel lblStatus = new JLabel(new ImageIcon(
                Main.class.getResource("/com/daniel/status1.png")));
        frame.getContentPane().add(lblStatus, BorderLayout.EAST);

        lblStatus.addMouseListener(new MouseAdapter() {

            public void mouseClicked(MouseEvent  arg0) {
            System.out.println("Clicked") 
            });

Answer 1

实现这一目标的一种方法是:

JLabel label = new JLabel("Click me");
        label.addMouseListener(new MouseListener() {
            public void mouseClicked(MouseEvent e) { System.out.println("Clicked me!"); }
            public void mouseEntered(MouseEvent e) {}
            public void mouseExited(MouseEvent e) {}
            public void mousePressed(MouseEvent e) {}
            public void mouseReleased(MouseEvent e) {}
        });

但是，正如建议的那样，最好在这里使用 JButton 和 ActionListener:

JButton button = new JButton("Push me");
        button.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                System.out.println("Pushed me!");
            }
        });
