Can't get a class to display properly (TabPanel awt)

Question

Hi, thank you checking this out.
I have renewed my interest for Java but need to start at the very beginning again. I have actuallu read up on AWT. Yes yes, I will follow up with Swing but for now I am just testing the waters again.
However, I cant manage even the simplest of tasks. I want to display a TabPanel and do see something in the created Frame but something is not correct (it certainly is not a TabPanel). Would you have a clue as to what I am doing wrong? The TabPanel is an OpenSource example and I actually do not expect anything wrong with it. It does work with getMinimumSize so I might skip a beat there. Any comment is appreciated.
This is what I build:
import java.awt.Frame;
import java.util.*;
public class TabPaneltest {
    public static void main (String args[]) {
          Frame f = new Frame();
          f.reshape(176,10,800,600);
        TabPanel T = new TabPanel();
          f.add(T);
          T.setVisible(true);
          f.show();
//                  (Still have to exit properly etc)// This is the TabPanel class as I found it, I am sure this is a usable error free component:
// Free to use, can't redistribute for profit
// Original by Pete Yared.
// Modified by Jean-Guy Speton ([email protected]).
//   Version 1.0.
//   * Changed name to TabPanel to differentiate modification tree
//     from original.
//   * JDK 1.1 API compliant.
//   * CardLayout used to simplify implementation.
//   * Added getMinimumSize() and getPreferredSize().
//   * Tab Font stored in state and created only once.
//   * Tab in index 0 now default selected.
//   * No longer repaints when user reselects selected tab.
// Still free to use, still can't redistribute for profit.
import java.awt.*;
import java.awt.event.*;
import java.util.Vector;
public class TabPanel extends Panel implements MouseListener
     protected Vector labels = new Vector();
     protected Vector panels = new Vector();
     protected Panel cardPanel = new Panel();
     protected int[] tabWidths;
     protected String selectedPanel;
     protected Font tabFont = new Font("Dialog", 12, Font.PLAIN);
     protected Insets insets;
     protected int tabHeight = 21;
     protected int tabWidthBuffer = 13;
     protected int insetPadding = 14;
     public TabPanel()
          insets = new Insets(insetPadding + tabHeight, insetPadding,
                                   insetPadding, insetPadding);
          setLayout(null);
          addMouseListener(this);
          cardPanel.setLayout(new CardLayout());
          add(cardPanel);
//  Sorry, can't put in full class because of a limit on the characters in the message.
//  Full code at: http://www2.blaze.ca/~jspeton/java/tabpanel/TabPanel.java     // As said, I'd love to have this thing working as to (start) give me back some 'feel' for java. (It would // look so much better than 'Hello World':) Your remarks are appreciated.

I have renewed my interest for Java but need to start at the very beginning again. I have actuallu read up on AWT. Yes yes, I will follow up with Swing but for now I am just testing the waters again.It is a bad idea, in this day and age, to ask AWT questions. The reason is that AWT coding is so distant (in time) for GUI programmers of this millennium, that they forget the details!
Besides that..
However, I cant manage even the simplest of tasks. ...Using an Open Source class is not 'the simplest of tasks'. Note also that:
a) We generally don't support 3rd party APIs on the forums. ..and..
b) Most people will absolutely refuse to..

.....follow a link to 'other code'. It is generally considered that if code is short enough to constitute 'an SSCCE' *(<- link),* then it is something short enough for them to look at. Any longer, and you've lost them.
An SSCCE is not only a short form of code, but very specific. I recommend you read up on the SSCCE, and post code in that specific form.
If you want some beginner projects to get you going again in Java, I recommend you put GUIs aside for a while do stuff intended to run from the command line. Use the Scanner class if you need interaction. When you get back to GUIs, launch directly into Swing, because that is the toolkit about which best help is to be had (and also includes a JTabbedPane supported by Sun!).
