public class NullJideButton
extends JideButton

This is part of the null-components. A null component doesn't have foreground, background or font value set. In the other words, the foreground, background and font value of null-component are null. But this doesn't mean getBackground(), getForeground() or getFont() will return null. According to Component.getBackground(), Component.getForeground() and Component.getFont(), if the value is null, it will get the value from its parent. In the other words, if you add a null-component to JPanel, you can use JPanel to control the background, foreground and font of this null-component. The feature is very helpful if you want to make sure all components in a JPanel has the same background, foreground or font.

We creates a few null-components. It doesn't cover all components. You can always create your own. All you need to do is this

 public class NullXxxComponent extends XxxComponent {
     // all the constructors
 

     public void updateUI() {
         super.updateUI();
         clearAttribute();
     }
 

     private void clearAttribute() {
         setFont(null);
         setBackground(null);
         // do not do this for JButton since JButton always paints button
         // content background. So it'd better to leave the foreground alone
         setForeground(null);
     }
 }
