Problem with run Java Applet

[Albert]

Just wondering if there is an easy way to transform java applications into applets.
For instance, say I have a class that looks like this:

Code:

import java.awt.*;
   import java.awt.event.*; 
   import javax.swing.*; 
   import javax.swing.JPanel;
   import javax.swing.JFrame;

public class TrackOperator extends JPanel{
    ...
     public static void main(String[] args){
         JFrame frame = new JFrame("TrackOperatorPanel");
         frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
         
         TrackOperator panel = new TrackOperator();
         frame.getContentPane().add(panel);    
         
         frame.pack();
         frame.setVisible(true);
    }
}

How would I make that run in an applet?
I know I need to import java.applet.*, also a init() and a stop() methods are needed.
Here is what I attempted so far:

Code:

import java.awt.*;
   import java.awt.event.*; 
   import javax.swing.*; 
   import javax.swing.JPanel;
   import javax.swing.JFrame;
   import java.applet.*;
	
    public class TrackOperatorApplet extends Applet{

       public void init(){
         JFrame frame = new JFrame("TrackOperatorPanel");
         frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
         
         TrackOperator panel = new TrackOperator();      
         frame.getContentPane().add(panel);    
         
         frame.pack();
         frame.setVisible(true);
         
         add(frame); //should add the frame to the applet???
      }
        
   
       public void stop(){}
   }

but when I open the html document where I embedded it, I get a blank screen.
Thanks.

If all you're doing is using the panel I believe you can do just an add on that panel, and not deal with the frame stuff.
That is instead of

Code:

add(frame);

do

Code:

add(panel)

But, I'm not completely sure. I never really wrote many java applets..

This is what I'm basing this idea off of:
