Hi,

When I press a JButton I want to add a panel panel to my UI.  How would I implement this?

Thanks,

Matt

Here is an example:

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class TestFrame extends JFrame {
   public TestFrame() {
      addWindowListener(new WindowAdapter() {
        public void windowClosing(WindowEvent e) {
          System.exit(1);
        }
      });

      JButton b = new JButton("Click me");
      b.addActionListener(new ActionListener() {
        public void actionPerformed(ActionEvent ae) {
           JPanel p = new JPanel();
           p.add(new JTextField(15));

           JButton button = (JButton)ae.getSource();
           Container c = button.getParent();
           c.add(p);
           pack();
        }
      });

      getContentPane().setLayout(new FlowLayout());
      getContentPane().add(b);
      pack();
      show();
   }

   public static void main(String[] args) {
       new TestFrame();      
   }
}
