Custom Dialog - please help

[AaronMweu Munzaa]

I have a class called "MyDialog" which is basically a JPanel with 2 textfields and a checkbox in a JFrame

I want to use "JOptionPane.showOptionDialog(Component parentComponent, Object message, String title, int optionType, int messageType, Icon icon, Object[] options, Object initialValue)" in the my main class and pass an instance of "MyDialog" as "Object message" but I have ended really confused and frustrated. Anyone who can bail me out?

Thanks.

You might consider either the hybrid or dialog options shown below. The static convenience method will require more work to extract the data from your components.

import javax.swing.*;
 
public class DialogTest
{
    static JTextField field1, field2;
    static JCheckBox check;
 
    public static void main(String[] args)
    {
        final JFrame f = new JFrame();
        final JButton
            option = new JButton("option"),
            hybrid = new JButton("hybrid"),
            dialog = new JButton("dialog");
        ActionListener l = new ActionListener()
        {
            public void actionPerformed(ActionEvent e)
            {
                JButton button = (JButton)e.getSource();
                if(button == option)
                    showOptionDialog(f);
                if(button == hybrid)
                    showHybridDialog(f);
                if(button == dialog)
                    showDialog(f);
            }
        };
        option.addActionListener(l);
