I add a JComboBox in a toolbar (inside a JFrame), and I'dlike to remove the border of the JComboBox. I can remove the border of the JButton of the toolbar, but I can't change the border of the JComboBox.
Setting a new border in it just adds the border to the default border of the JComboBox, but does not replace it.

This is a piece of code which reproduce the problem :

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

public class JComboProblem extends JFrame
{

public JComboProblem()
{
super();

addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent ev) {
System.exit(0);
}
});

JPanel panel = new JPanel(new BorderLayout());
getContentPane().add(panel);

JToolBar tb = new JToolBar();
panel.add(tb, BorderLayout.NORTH);

JButton button = new JButton("Do nothing");
button.setBorderPainted(false);
tb.add(button);

JComboBox cb = new JComboBox();

cb.addItem("25%");
cb.addItem("50%");
cb.addItem("100%");
cb.addItem("200%");

cb.setMaximumSize(cb.getMinimumSize());
tb.add(cb);

// cb.setBorder(null); // Do nothing
cb.setBorder(BorderFactory.createEmptyBorder(0, 0, 0, 0)); // Do nothing
// cb.setBorder(BorderFactory.createEtchedBorder()); // Adds the border to the existing border but does not replace it

setSize(400, 300);
setVisible(true);
}

public static void main(String argv[])
{
new JComboProblem();
}
}

I could be useful to have a JComboBox.setBorderPainted (and JComboBox.setFocusPainted) method(s).
