Trying to fade out a font

[Kurt Harless]

This seems like it should be easy: But Alas, what I am left with is a WHITE "S" on a light gray frame, instantly, the timers don't seem to slow it down! How do I get the letter "S' to gradually fade to white? Tried a thread with a sleep method but that kept the frame from repainting until the end.

It is late and my brain just cant wrap around this problem.

Any and all help or direction greatly appreciated!

timer works OK like this

    
import java.awt.Font;
import java.awt.Color;
import java.awt.Graphics;
import javax.swing.JPanel;
import java.util.*;
import java.awt.event.*;
import javax.swing.JFrame;

class Letters
{
   public static void main( String args[] )
   {
      JFrame frame = new JFrame( "Fading" );
      frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );

      LetterPanel fontJPanel = new LetterPanel();
      frame.add( fontJPanel );
      frame.setSize( 640, 480 );
      frame.setVisible( true );
   }
}
class LetterPanel extends JPanel
{
    Color color = Color.RED;
    int colorCode = 50;
    javax.swing.Timer timer;
    public LetterPanel()
    {
      timer = new javax.swing.Timer(250,new ActionListener(){
        public void actionPerformed(ActionEvent ae){
          color = new Color(255,colorCode,colorCode);
          colorCode += 50;
          if(colorCode == 250) colorCode += 5;
          repaint();
          if(colorCode == 255) timer.stop();
        }
      });
      timer.setInitialDelay(1000);
      timer.start();
    }
    public void paintComponent(Graphics g)
    {
        super.paintComponent(g);
        g.setColor(color);
        g.setFont(new Font("SansSerif", Font.PLAIN + Font.BOLD, 100));
        g.drawString("S", 100, 110);
    }
}

Awesome, Thanks!

Didn't even know about SWING timers... Learn 10 new things a day!

Sounds like something which would sit better on the Swing Forum. Moving.
