I hope this helps

That's it! Thank you.

Color.black is better.

I don't know what you're doing but I know it must be something strange ;)


Michael's example (using an static inner class ) is fine, just didn't
understand why for standalone class, we have to explixitly set the
foreend color.

You do *not* need to. It doesn't make any difference if one uses a static inner class or a top level class:

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

class MyComboBox extends JComboBox implements ActionListener {
public void actionPerformed( ActionEvent e ) {
System.out.println( "Action" );
}

public MyComboBox() {
addItem("a");
addItem("b");
addItem("c");
setEditable( false );
addActionListener( this );
}
}

public class Test {
public static final void main( String args[] ) throws Exception {
JFrame frame = new JFrame("Test");
frame.setDefaultCloseOperation( JFrame.DISPOSE_ON_CLOSE );
frame.setContentPane( new MyComboBox() );
frame.pack();
frame.setVisible( true );
}
}

Again, post an SSCCE of the problem.

Bye
Michael
