Hello. I am busy writing a java applet, but I have encountered the following problems:
1. When I click on the Blue button, it is suppose to change the background colour to blue. When I click on the Black button, it is suppose to change the background colour to black.Butwhen I click on them, these two actions are not performed. My buttons are working, as I am able to change the caption of the buttons when I click on the buttons, but it does not want to change the background color.
2. When my applet loads, it only loads the west button.When I hover over the position where the second button is supposed to be, it suddenly appears. I have attached my .java and .class files with a screenshot.
I will REALY appreciate your help if you can help me asap as this is quite urgent. Thank you.
Here is my code :
<CODE>
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JPanel;
import javax.swing.JButton;
import java.awt.Color;
import javax.swing.JApplet;
import java.awt.Graphics;
/**

public class myApplet extends JApplet implements ActionListener{
/**
* Initialization method that will be called after the applet is loaded
* into the browser.
*/
private JButton btnSetToBlack,btnSetToBlue;
private BorderLayout layout;
public void init() {
layout = new BorderLayout(50,50);
setLayout(layout);
btnSetToBlack = new JButton("BLACK");
btnSetToBlue = new JButton("BLUE");
add(btnSetToBlack,BorderLayout.EAST);
add(btnSetToBlue,BorderLayout.WEST);
this.setSize(800,600);
this.setBackground(Color.GRAY);
this.setVisible(true);
btnSetToBlack.addActionListener(this);
btnSetToBlue.addActionListener(this);
}
// TODO overwrite start(), stop() and destroy() methods
public void paint(Graphics g)
{
// g.drawRect(100, 50, 150, 200);
}
public void start()
{
}
public void actionPerformed(ActionEvent event)
{
if (event.getSource() == btnSetToBlack)
{
this.setBackground(Color.BLACK);
btnSetToBlack.setText("clicked");
repaint();
}
if (event.getSource() == btnSetToBlue)
{
this.setBackground(Color.BLUE);
btnSetToBlue.setText("clicked");
repaint();
}
}
}
</CODE>
