    In the Java applet below, i'm trying to make the text box change color when the slider is moved to the left and right. Right now when I move the JSlider left or right the text in the text box changes color. How do I get the text box the change color ??????


    import java.awt.Dimension;
    import java.awt.event.MouseEvent;
    import java.awt.event.MouseMotionAdapter;

    import javax.swing.JApplet;
    import javax.swing.JTextField;
    import javax.swing.JComponent;
    import javax.swing.JFrame;
    import javax.swing.JSlider;
    import javax.swing.SwingUtilities;
    import java.util.Random;
    import java.awt.Color;

    public class Main extends javax.swing.JApplet {
    private JTextField aTextField;
    private JSlider aSlider;

    public static void main(String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
    public void run() {
    JFrame frame = new JFrame();
    Main inst = new Main();
    frame.getContentPane().add(inst);

    frame.pack();
    frame.setVisible(true);
    }
    });

    }

    public Main() {
    super();
    initGUI();
    }

    private void initGUI() {
    try {
    setSize(new Dimension(200, 200));
    getContentPane().setLayout(null);
    {
    aTextField = new JTextField();
    aTextField.setBackground(Color.white);
    getContentPane().add(aTextField);
    aTextField.setText("How do I make the whole text box change color ?");
    aTextField.setBounds(65, 80, 300, 80);
    }
    {
    aSlider = new JSlider();
    aSlider.setBackground(Color.yellow);

    getContentPane().add(aSlider);
    aSlider.setBounds(65, 200, 300, 80);
    aSlider.addMouseMotionListener(new MouseMotionAdapter() {
    public void mouseDragged(MouseEvent evt) {
    aSliderMouseDragged(evt);

    }
    });
    }
    } catch (Exception e) {
    e.printStackTrace();
    }
    }

    private void aSliderMouseDragged(MouseEvent evt) {
    Random r = new Random();
    int red = Math.abs(r.nextInt())%200;
    int green = Math.abs(r.nextInt())%100;
    int blue = Math.abs(r.nextInt())%100;
    aTextField.setForeground(new Color(red, green, blue));
    }
    }
