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));
}
}

Java Code:

aTextField.setForeground(new Color(red, green, blue));

So instead of the above you want to do this:

Java Code:

aTextField.setBackground(new Color(red, green, blue));

That didn't take a rocket scientist to think of it ... Did you write the code of that applet yourself?

kind regards,

Jos

Yup, the answer is identical to my answer. We'll see if the poster returns here after spamming (almost) the entire net with his trivial question.

kind regards,
