How do I create an event handler for a JLabel?

Question

Below is the code I’ve:  

public class Picture extends JFrame  {

    private ImageIcon _image1;

    private ImageIcon _image2;

    private JLabel _mainLabel;

    private JLabel _mainLabel2;

    public Picture(){

        _image1 = new ImageIcon("src/classes/picture1.jpg");

        _image2 = new ImageIcon("src/classes/picture2.jpg");

        _mainLabel = new JLabel(_image1);

        _mainLabel2 = new JLabel(_image2);

        add(_mainLabel);

        pack();

        setVisible(true);

        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    }

}

 I want to click on the JLabel, which makes a new label with another image attached to it. Can anyone tell me how to do it?

Answer 1

You can add mouseListener to the JLable and in the mouseClicked(mouseEvent) method change the icon of JLabel.

Check out the below code implementation: 

  jLabel.addMouseListener(new MouseAdapter() {

        @Override

        public void mouseClicked(MouseEvent e) {

            jLabel.setIcon(newIcon);

        }

    });
