SetForeground in Applet does not work (Netbeans under Linux)

Question

I'm attempting to make a Breakout version of java (if I go through with it) and the first issue that I encountered is that I can't change the color of the moving rectangle (you know, the thing you hit the ball with). I tried the code under Textpad on a Windows machine and that worked fine, but not under Netbeans in Linux using jdk 1.6.0_01.
import java.awt.*;
import java.applet.*;
import java.awt.event.*;
public class Breakout extends Applet implements MouseListener, MouseMotionListener{
     int mouse_x, mouse_y;
     Thread t;
     public void init(){
          addMouseListener(this);
          addMouseMotionListener(this);
     public void start(){
          t= new Thread();
          t.start();
     public void run(){}
     public void mouseClicked(MouseEvent me){ }
     public void mouseEntered(MouseEvent me){ }
     public void mouseExited(MouseEvent me){ }
     public void mousePressed(MouseEvent me){ }
     public void mouseReleased(MouseEvent me){ }
     public void mouseDragged(MouseEvent me){ }
     public void mouseMoved(MouseEvent me){
          mouse_x = me.getX();
          if(mouse_x>=400)
               mouse_x=400;
          repaint();
     public void stop() {}
     public void destroy(){ }
     public void paint(Graphics g){
          setBackground(Color.black);
          setForeground(Color.white); //doesn't work              
          g.drawRoundRect(mouse_x, 600, 50, 20, 20, 20);
}I'm wondering if it's because the Applet under Linux uses the Native l&f theme while appets under Windows uses the Windows l&f theme.
Any thoughts would be helpful!

Answer 1

setForeground(Color.white); //doesn't work
g.drawRoundRect(mouse_x, 600, 50, 20, 20, 20);Change this to:
g.setColor(Color.WHITE);
g.drawRoundRect(mouse_x, 600, 50, 20, 20, 20);You can move the background setting into method init(), calling it once is enough.

uses the Windows l&f theme.You use java.awt.Applet, so you use AWT which means there's no L&F theme (as in Swing) but it's native components being responsible.
