How can I get Multi-color text it a swing componet?

Question

How can I get Multi-color text it a swing componet?
I've tryed JTextPane and JEditorPane.
If they support having text in more then one color then I don't see how.
I want to make a color-coded Java editor in Java, but I can't color-code if I can only have one color.
JComponent.setForeground(Color fg)
is not what I need.
maybe Java doesn't support it yet.
but I hope it does.
Please help, thanks.

Hi,
I've made you a little example with a coloured JEditorPane and JTextPane:
import javax.swing.*;
import javax.swing.text.*;
import java.awt.*;
import java.awt.event.*;
public class ColorDemo extends JFrame {
     public ColorDemo() {
          super("ColorDemo");
          // coloured JEditorPane
          JEditorPane editorPane = new JEditorPane("text/html",
               "<FONT color=red> This </FONT>"+
               "<FONT color=blue> is </FONT>"+
               "<FONT color=green> a </FONT>"+
               "<B> JEditorPane </B>");
          editorPane.setPreferredSize(new Dimension(250, 150));
          // coloured JTextPane
          JTextPane textPane = new JTextPane();
          textPane.setPreferredSize(new Dimension(250, 150));
          Document doc = textPane.getDocument();
          Style def = StyleContext.getDefaultStyleContext().
               getStyle(StyleContext.DEFAULT_STYLE);
          try {
               StyleConstants.setForeground(def, Color.blue);
               doc.insertString (0, "This ", def);
               StyleConstants.setForeground(def, Color.red);
               doc.insertString (5, "is ", def);
               StyleConstants.setForeground(def, Color.green);
               doc.insertString (8, "a ", def);
               StyleConstants.setBold(def, true);
               StyleConstants.setForeground(def, Color.black);
               doc.insertString (10, "JTextPane", def);
          } catch (Exception e) {}
          JPanel contentPane = new JPanel();
          contentPane.add(textPane);
          contentPane.add(editorPane);
          setContentPane(contentPane);
     public static void main(String[] args) {
          JFrame frame = new ColorDemo();
          frame.addWindowListener(new WindowAdapter() {
               public void windowClosing(WindowEvent e) {
                    System.exit(0);
          frame.pack();
          frame.setVisible(true);
}Hope this helps,
Kurt.
