How to add jlabel image hovering?

Question

How would I go upon adding `JLabel` hovering? Like when you move your mouse over top a `JLabel` a and new image will overlap it. I know how to make it work with buttons, but the same technique will not work for `JLabel`s. Will anyone guide me towards adding `JLabel` hovering? Please and thanks. ``` package src; import java.awt.Dimension; import javax.swing.ImageIcon; import javax.swing.JFrame; import javax.swing.JLabel; /* * @Author - 0x29A * * */ public class Jframe { public static void main(final String args[]) { /* * @Images */ final ImageIcon icon = new ImageIcon("Data/button.png"); final JLabel label = new JLabel(icon); final ImageIcon icon1 = new ImageIcon("Data/button1.png"); final JLabel label1 = new JLabel(icon1); final ImageIcon icon2 = new ImageIcon("Data/button2.png"); final JLabel label2 = new JLabel(icon2); final ImageIcon icon3 = new ImageIcon("Data/button3.png"); final JLabel label3 = new JLabel(icon3); final ImageIcon icon4 = new ImageIcon("Data/button4.png"); final J…

Accepted Answer

Made a quick example, it uses a `MouseListener` and `MosueAdapter` to monitor `mouseExited()` and `mouseEntered()` events on the `JLabel`, and when either of these methods are called (i.e when the mouse is over the label or not) the picture is changed:

```
import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.event.MouseAdapter;
import javax.swing.*;

public class LabelHoverTest extends JFrame {

Icon pic1;
    Icon pic2;
    JLabel label;

public LabelHoverTest(String title) {
        super(title);
        pic1 = UIManager.getIcon("OptionPane.informationIcon");
        pic2 = UIManager.getIcon("OptionPane.questionIcon");
        createAndShowUI();
    }

public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {

@Override
            public void run() {
                new LabelHoverTest("Label Hover Test").setVisible(true);
            }
        });
    }

private void createAndShowUI() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setResizable(false);
        addComponentsToPane(getContentPane());
        setSize(300, 300);
        setLocationRelativeTo(null);
        setVisible(true);
    }

private void addComponentsToPane(Container contentPane) {
        label = new JLabel(pic1);

contentPane.add(label, BorderLayout.CENTER);

label.addMouseListener(new MouseAdapter() {

@Override
            public void mouseEntered(java.awt.event.MouseEvent evt) {
                label.setIcon(pic2);
            }

@Override
            public void mouseExited(java.awt.event.MouseEvent evt) {
                label.setIcon(pic1);
            }
        });
    }
}
```
