Simple Swing problem

[Arom]

Hi,

I've started learning Swing recently. I've built a simple application, however, whenever I am trying to add a new JTextField to the top (NORTH) of my panel, it just does not want to appear. Here's a chunk of code ;

public class CounterPanel extends JPanel {
    private CounterModel counter;
    private JLabel valueLabel;
    JButton upButton, downButton, resetButton;
 private JTextField inputField;

    public CounterPanel() {
        //setup the layout
        this.setLayout(new BorderLayout());
        
        //create model and its display:
        counter = new CounterModel();    
        valueLabel = new JLabel(""+counter.getValue(),SwingConstants.CENTER);
        this.add(valueLabel,BorderLayout.CENTER);

        //setup the listener (include a link back to here so that it can update)
        CounterListener countList = new CounterListener(this);  
        
        //now do the buttons

     inputField = new JTextField("0");    //Text Field
this.add(inputField,BorderLayout.NORTH); // Position

upButton = new JButton("Up"); //create a button
this.add(upButton,BorderLayout.WEST); //position it
upButton.addActionListener(countList); //set listener to listen 

downButton = new JButton("Down"); //ditto
this.add(downButton,BorderLayout.EAST);
downButton.addActionListener(countList);

resetButton = new JButton("Reset"); //ditto
this.add(resetButton,BorderLayout.SOUTH);
resetButton.addActionListener(countList);
    }

Obviously, I have been adding JTextField in other projects, and they seem to work perfectly. I just cannot understand why it doesn't appear on this example.

Thanks

Posted code looks reasonable.
