      net.xoetrope.swing.util.XComponentUiHelper

public class XComponentUiHelper
extends javax.swing.plaf.ComponentUI

A helper to set a ComponentUI painter. The painter must extend the UI appropriate delegate for the component.

 public class XButtonUI extends ButtonUI
 {
   ButtonUI ui;
   
   public void setup( JButton c )
   {
     ui = (ButtonUI)XComponentUiHelper.setUI( (JComponent)c, this );
   }
     
   // Paints an X over the button.
   public void paint(Graphics g, JComponent c) 
   {
     // Invoke the original UI delegate
     ui.paint( g, c );
     ComponentUI ui2 = UIManager.getUI( c );
     
     // Now do the custom painting
     Rectangle r = c.getBounds();
     g.setColor( Color.red );
     g.drawLine( 0, 0, r.width, r.height );
     g.drawLine( 0, r.height, r.width, 0 );
   }  
 }
 

 Then, to install the painter delegate:

    new XButtonUI().setup( submitBtn );
