Update JTable from a JDialog

Question

I'm wanting to update a JTable I have on a JFrame. This JFrame has a button on it which opens a JDialog box which populates a database. The main JFrame's JTable (ReceivedTable) holds this information. When a user inputs some more information and closes the dialog, I'd like to update the JTable in the main JFrame, but am not sure how to go about doing this. Can someone give me an idea to work from.
Thanks.

G'day mate,
Make an extension of JDialog like so:
//import appropriate classes here
public class MyDialog extends JDialog implements ActionListener {
     //you would have some text fields or such here
     public MyDialog(Frame parent, String name) {
          super(parent, name, true);
          JPanel cp = (JPanel)getContentPane();
          //cp.add(fields here!);
          JButton submit = new JButton("Submit");
          submit.addActionListener(this);
          cp.add(submit);
     public void actionPerformed(ActionEvent ae) {
          Vector data = new Vector();
          //populate 2d data vector with data for the table
          Vector column_names = new Vector();
          //names for your table columns
          ((DefaultTableModel)((JFrame)getOwner()).getTable().getModel()).setDataVector(data, column_names);
          dispose();
Note: In your JFrame you will need to define a method getTable().
I think that should work for you... Obviously you'll have to add in a lot of code yourself, but that should be a reasonable skeleton.
Good luck,
Muel.
