J2ME,GameCanvas and Thread

And here is the GameCanvas class

package MyApp;

import java.io.IOException;
import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;
import java.lang.Runnable.*;

public class MyGameCanvas extends GameCanvas implements Runnable
{    
  private boolean vRenderLoop;
  private int vXPos;
  private int vWidth;
  private int vHeight;
  
  MyGameCanvas()
  {
      super(true);
      System.out.println("Constructor called");      
      vXPos=0;
      vWidth=getWidth();
      vHeight=getHeight();
      vRenderLoop=false;   
  }
  
  public void paint(Graphics g)
  {
   
  }  
  public void start()
  {
      System.out.println("start invoked");
      vRenderLoop=true;
      Thread t = new Thread(this);
      t.start();
  }
  
  public void stop()
  {
      vRenderLoop=false;
  }
  
  public void render(Graphics g)
  {
      g.setColor(0xffffff);
      g.fillRect(0,0,vWidth,vHeight);
      vXPos++;
      g.setColor(0x000000);
      g.fillRect(vXPos, 50, 100,100);
      
      if(vXPos > (100 + vWidth))
          vXPos=0;
  }
  
  public void run()
  {
      System.out.println("yeah yeah");
      Graphics g = getGraphics();
      while(vRenderLoop)
      {
        render(g);
        flushGraphics();
        try { Thread.sleep(10);}
        catch (InterruptedException ie)
        {
            stop();
        }        
      }
  }
}

Note that I have removed the content from paint() and pumped them into render(Graphics g) instead. Also notice the use of flushGraphics() here. And yes super(true) in the constructor.
