Create a Label With Underlined Text

The following class will give you a label with underlined text.
 
    public class UnderlinedLabel extends java.awt.Label  
    {
        public UnderlinedLabel()
        {
            this("");    
        }

        public UnderlinedLabel(String text)
        {
            super(text);    
        }

        public void paint(Graphics g) 
        {
            Rectangle r;
            super.paint(g);
            //here's the trick
            r = g.getClipBounds();
            g.drawLine(0,
                       r.height -
this.getFontMetrics(this.getFont()).getDescent(), 
 
this.getFontMetrics(this.getFont()).stringWidth(this.getText()),  
                       r.height -
this.getFontMetrics(this.getFont()).getDescent()
                       );
        }
Now if you have a panel called p on a form or dialog, you can:
 
	UnderlinedLabel ull = new UnderlinedLabel();
	Rectangle r = new Rectangle(5,5,150,30);
	ull.setBounds(r);
	ull.setText("I'M UNDERLINED");		
	panel1.add(ull);
You'll have a label showing underlined text.
