JToolTip with components in it

Question

I want a tooltip to have a list (or basically a panel) inside it. How can I do this? I've read about including icons inside tooltips by doing icon.paintIcon but I havent had any luck doing this with JList.
So how can I include a panel in a tooltip?
thanks

Here's how you can do it:import javax.swing.*;
import java.awt.*;
public class MBTestApplication extends JFrame {
    public MBTestApplication() {
        JPanel customPanelForToolTip = new JPanel();
        customPanelForToolTip.setBackground(Color.red);  //just to prove it's there ;-)
        eJButton b = new eJButton("Click Here", customPanelForToolTip);
        b.setToolTipText("");  //just to get it to display tooltips
        getContentPane().add(b);
    public static void main(String[] args) {
        JFrame f = new MBTestApplication();
        f.setBounds(100,100,300,300);
        f.show();
class eJButton extends JButton {
    JPanel customToolTipPanel;
    public eJButton(String s, JPanel toolTipPanel) {
        super(s);
        customToolTipPanel = toolTipPanel;
    public JToolTip createToolTip() {
        JToolTip tip = new eJToolTip(customToolTipPanel);
        tip.setComponent(this);
        tip.setPreferredSize(new Dimension(100,50));
        return tip;
class eJToolTip extends JToolTip {
    public eJToolTip(JPanel customToolTipPanel) {
        super();
        setLayout(new BorderLayout());
        add(customToolTipPanel, BorderLayout.CENTER);
}
