Please i have a class that extends jlabel and draw on it using paintComponent as follows this is

package myApp;
import java.awt.*;
import javax.swing.*;
* @author PAGOLINA
public class paintPhotos extends javax.swing.JLabel {

public Image img; int w; int h;
public paintPhotos(Image img, int w, int h) {
this.img = img; this.w = w; this.h = h;
System.out.println("am paintclass");
public void paintComponent(Graphics p) {
System.out.println("am here");
Graphics2D g2 = (Graphics2D) p;
p.drawImage(img, 0, 0, w, h, this);


when i try to draw from a constructor of another class like this (

public AddScore() {
Image imag = new ImageIcon(this.getClass().getResource("img/top_bg.jpg")).getImage();
showPix1.setLayout(new BorderLayout());
showPix1.add(new paintPhotos(imag,40,40), BorderLayout.CENTER);

the above work fine and draw the image as specified.

but when i try to draw the image from an actionperform event of another class ( like this.

private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
Image imag = new ImageIcon(this.getClass().getResource("img/top_bg.jpg")).getImage();
showPix1.setLayout(new BorderLayout());
showPix1.add(new paintPhotos(imag,20,20), BorderLayout.CENTER);

the above statement did not work as the paintcomponent is not working, what am i doing wrong?
