Why is my java applet blank? (Simple)

Question

I just tried to make an applet with a textbox, a label and a button, but nothing shows up!
Here's the code I'm using:
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.swing.*;
import java.awt.event.*;
public class TestApplet extends JApplet{
  JFrame fFrame;
  JLabel label1 = new JLabel("Label: ", JLabel.LEFT);
  JTextField txtbox = new JTextField(10);
  JButton btnStart = new JButton("Press Here");
  JPanel MainPanel = new JPanel();
  public void init () {
      MainPanel.setSize(300, 300);
      txtbox.setSize(60,20);
      btnStart.setSize(60,20);
      MainPanel.add(label1);
      MainPanel.add(txtbox);
      MainPanel.add(btnStart);
      add(MainPanel);
  } // init
}Anyone has an idea what I am doing wrong?

Answer 1

What output/result do you get from this code?
// <applet code="TestAppletLayout" width="300" height="100"></applet>
import javax.swing.*;
public class TestAppletLayout extends JApplet{
  JFrame fFrame;
  JLabel label1 = new JLabel("Label: ", JLabel.LEFT);
  JTextField txtbox = new JTextField(10);
  JButton btnStart = new JButton("Press Here");
  JPanel MainPanel = new JPanel();
  public void init () {
      System.out.println( MainPanel.getLayout() );
      MainPanel.add(label1);
      MainPanel.add(txtbox);
      MainPanel.add(btnStart);
      add(MainPanel);
      validate();
  } // init
}
