JRadioButton: how to replace text by IconImage?

Question

I want to replace the text in my radio button list by an icon.

I\'ve tried this:

rotateButton = new JRadioButton(rotateIcon.getImage());

I just reproduced your described behavior using this source:

import java.awt.Image;
import javax.swing.*;
import javax.imageio.ImageIO;
import java.net.URL;

class RadioWithImage {

    public static void main(String[] args) throws Exception {
        URL url = new URL("http://www.gravatar.com/avatar/" +
            "a1ab0af4997654345d7a949877f8037e?s=128");
        Image image = ImageIO.read(url);
        final ImageIcon imageIcon = new ImageIcon(image);
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                JRadioButton radioButton = new JRadioButton("A.T.", imageIcon);
                JOptionPane.showMessageDialog(null, radioButton);
            }
        });
    }
}

It seems like a bug to me, though I cannot recall seeing a radio with an icon. How are they supposed to look?

Time to reach into my 'box of hacks'.

import javax.swing.*;

class RadioWithImage {

    public static void main(String[] args) throws Exception {
        String url = "http://www.gravatar.com/avatar/" +
            "a1ab0af4997654345d7a949877f8037e?s=128";
        final String html = "";
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                JRadioButton radioButton = new JRadioButton(html);
                JOptionPane.showMessageDialog(null, radioButton);
            }
        });
    }
}

This technique will not work if:

1. The use-case requires other types of icons (pressed, roll-over, selected etc.)
2. The button is disabled (it will render incorrectly).
