Hi DarrylBurke,
Sure i will.
But i have posted that code after trying all the possibilities.
I thought that getUI() failed exception may have the resulkt for not implementing any method or any registration problem with UIManager.
So, that is my test code not exactly i have posted that in hurry.
Here is the code :
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Rectangle;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.accessibility.Accessible;
import javax.swing.AbstractButton;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.UIManager;
import javax.swing.plaf.ComponentUI;
import javax.swing.plaf.basic.BasicButtonListener;
import javax.swing.plaf.metal.MetalButtonUI;

    protected void paintText(Graphics g, AbstractButton b, Rectangle textRect, String text)
        g.setColor(Color.RED);
        super.paintText(g,b,textRect,text);
}Can you please suggest me the possible solution for this problem.
Thank You DarrylBurke
