JApplet does not resize correctly

Question

Hello,
I'm trying to practice with JLayeredPane in JApplet.
The problem is that when i resize the applet JButton b3 is painted "as a background", and still works as a JButton.
Why doesn't it resize correctly as the other JComponent do?
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class JLayeredPaneDemo extends JApplet {
     public void paint(Graphics g) {
          final JLabel l1 = new JLabel("LABEL 1",JLabel.CENTER);
          final JLabel l2 = new JLabel("LABEL 2",JLabel.CENTER);
          final JLabel l3 = new JLabel("LABEL 3",JLabel.CENTER);
          resize(400,300);
          l1.setOpaque(true);
          l1.setBackground(Color.blue);
          l1.setBorder(BorderFactory.createLineBorder(Color.black,2));
          l2.setOpaque(true);
          l2.setBackground(Color.green);
          l2.setBorder(BorderFactory.createLineBorder(Color.black,2));
          l3.setOpaque(true);
          l3.setBackground(Color.yellow);
          l3.setBorder(BorderFactory.createLineBorder(Color.black,2));
          l1.setBounds(0,0,100,100);
          l2.setBounds(30,30,100,100);
          l3.setBounds(60,60,100,100);
          getLayeredPane().add(l1,new Integer(1));
          getLayeredPane().add(l2,new Integer(2));
          getLayeredPane().add(l3,new Integer(3));
          JButton b1 = new JButton("LABEL 1 ON TOP");
          JButton b2 = new JButton("LABEL 2 ON TOP");
          JButton b3 = new JButton("LABEL 3 ON TOP");
          b1.setBounds(220,0,150,40);
          b2.setBounds(220,40,150,40);
          b3.setBounds(220,80,150,40);
          b1.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    if(getLayeredPane().getLayer(l2)>getLayeredPane().getLayer(l3))
                         getLayeredPane().setLayer(l1,new Integer(getLayeredPane().getLayer(l2)+1));
                    else
                         getLayeredPane().setLayer(l1,new Integer(getLayeredPane().getLayer(l3)+1));
          b2.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    if(getLayeredPane().getLayer(l1)>getLayeredPane().getLayer(l3))
                         getLayeredPane().setLayer(l2,new Integer(getLayeredPane().getLayer(l1)+1));
                    else
                         getLayeredPane().setLayer(l2,new Integer(getLayeredPane().getLayer(l3)+1));
          b3.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e) {
                    if(getLayeredPane().getLayer(l1)>getLayeredPane().getLayer(l2))
                         getLayeredPane().setLayer(l3,new Integer(getLayeredPane().getLayer(l1)+1));
                    else
                         getLayeredPane().setLayer(l3,new Integer(getLayeredPane().getLayer(l2)+1));
          add(b1);
          add(b2);
          add(b3);
}If i use the init() method instead of the paint(Graphics g) method JButton b3 is painted as large as possible since the beginning.
thanx in advance :)

Swing related questions should be posted in the Swing forum.
If i use the init() method instead of the paint(Graphics g) methodWell, thats the proper way to write a Swing applet. The code for building the GUI should be in the init() method. You never need to override the paint() method of the JApplet.
Components will not be automatically resized when the size of the applet changes. A layered pane does not use a layout manager, therefore it is up to you to manually change the size of each component. You can add a ComponentListener to the applet to be notified when the size changes.
