No checkboxes and very big comboboxen when creating own L&F

Question

Hello,
I wanted to create my own look and feel bij extending from BasicLookAndFeel. M class:
import javax.swing.plaf.basic.*;
import javax.swing.*;
public class PlanonLookAndFeel extends BasicLookAndFeel
//~ Constructors ................................................
* @return The name for this look-and-feel.
public String getName()
return "Planon";
* We are not a simple extension of an existing
* look-and-feel, so provide our own ID.
* <p>
* @return The ID for this look-and-feel.
public String getID()
return "Planon";
* @return A short description of this look-and-feel.
public String getDescription()
return "The Planon Look and Feel";
* This is not a native look and feel on any platform.
* <p>
* @return false, this isn't native on any platform.
public boolean isNativeLookAndFeel()
return false;
* This look and feel is supported on all platforms.
* <p>
* @return true, this L&F is supported on all platforms.
public boolean isSupportedLookAndFeel()
return true;
protected void initSystemColorDefaults(UIDefaults table)
String[] defaultSystemColors = {

loadSystemColors(table, defaultSystemColors, isNativeLookAndFeel());
This works oke, but when i try to display a combox, it looks really ugly (a very big arrow and no borders). The checkbox isn't even displayed. Does anyone have a clue about this?
Thanks in advance
