adding a row to JTable

[H Melua]

Hi

I'm trying to make my applet display the item i add in a JTable but its not really doing anything! (basically i want to add a row)
can someone please tell me whats wrong with my code? (the applet initialises and the tables and buttons are displayed correctly)

public class ItemApplet extends Applet implements ActionListener {
    ....
    Object[] data = new Object[2];
    private String[] columnNames = {"Description", "Quantity", "Exiry Date"};
    private Object[][] data1 = {{"", "", ""}};
    private DefaultTableModel model = new DefaultTableModel(data1, columnNames);
    private JTable table = new JTable(model);
    private JTable table2 = new JTable(model); 
 
    public void initApplet(int maxItems){
        table.setPreferredScrollableViewportSize(new Dimension(500, 70));
        JScrollPane scrollPane = new JScrollPane(table);
    }
 
    public void actionPerformed(ActionEvent e){
         if( e.getSource() == addButton){
                String des = descriptionField.getText();
                double price = Double.parseDouble(priceField.getText());
                try{
                    DateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
                    String exDate = exDateField.getText();
                    java.sql.Date sqlExDate = new java.sql.Date(sdf.parse(exDate).getTime());
 
                    data[0] = des;
                    data[1] = priceField.getText();
                    data[2] = exDate;
                    model.addRow(data);
                    table.setModel(model);
                        
                }catch(ParseException ex){}
          }
     }
}

thanks

Here's some code that does work (I don't do applets)

import java.awt.*;
import java.awt.event.*;
import java.util.*;
import javax.swing.*;
import javax.swing.table.*;
 
public class TableExample {
    public static void main(String[] args) {
        String[] columnNames = {"Column 0", "Column 1", "Column 2"};
        final DefaultTableModel model = new DefaultTableModel(columnNames, 0);
        JPanel buttons = new JPanel();
        JButton add = new JButton("add a row");
        add.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent evt) {
                model.addRow(new Object[]{new Date(), "etc...", "etc..."});
            }
        });
        buttons.add(add);
        final JFrame f = new JFrame("TableExample");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Container cp = f.getContentPane();
        cp.add(new JScrollPane(new JTable(model)), BorderLayout.CENTER);
        cp.add(buttons, BorderLayout.SOUTH);
        f.pack();
        SwingUtilities.invokeLater(new Runnable(){
            public void run() {
                f.setLocationRelativeTo(null);
                f.setVisible(true);
            }
        });
    }
}

I'm suspicous of your catch. What if exceptions are being thrown? You should at least e.printStackTrace() to see what's happening, and open you applet's console window to check!

yes your right about the catch, there is a bit of coding there, but i didnt put it since its not part of the question...

thanks again
