I dvlp MyPanel to accept 2 image file name.
You can easy change to accept Image instead of file name.
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
public class Test {
public static void main(String args[]) {
JFrame f = new JFrame("Test");
MyPanel p = new MyPanel("YourFirstImage.gif", "YourSecondImage.gif");
p.add(new JButton("Click on Panel (not Button)"));
f.setContentPane(p);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.pack();
f.setVisible(true);
class MyPanel extends JPanel implements MouseListener {
Image image, image1, image2;
public MyPanel(String image1Name, String image2Name) {
//load image
try {
image1 = getToolkit().getImage(getClass().getResource(image1Name));
image2 = getToolkit().getImage(getClass().getResource(image2Name));
MediaTracker mt = new MediaTracker(this);
mt.addImage(image1, 0);
mt.addImage(image2, 0);
mt.waitForAll();
} catch (Exception e) { e.printStackTrace(); }
this.image1 = image1;
this.image2 = image2;
this.image = image1;
this.addMouseListener(this);
public void paintComponent(Graphics g) {
g.drawImage(image, 0, 0, this.getWidth(), this.getHeight(), this);
public void mouseClicked(MouseEvent e){
image = (image == image1) ? image2 : image1; // switch between image1, image2
repaint();
public Dimension getPreferredSize() {
Dimension dim = super.getPreferredSize();
int w = Math.max(image1.getWidth(this), image2.getWidth(this));
int h = Math.max(image1.getHeight(this), image2.getHeight(this));
w = Math.max(dim.width, w);
h = Math.max(dim.height, h);
return new Dimension(w, h);
public void mouseEntered(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mousePressed(MouseEvent e) {}
public void mouseReleased(MouseEvent e) {}
