PrintDialog in WordProcessor

Question

Hi,
Im trying to insert this dummy print function in my Wordprocessor, the code generates a new dialog with a textfield and continues generating random numbers every 2 seconds in the textfield.
Here is the code for the wordprocessor & print functions
Any help much appreciated..........

Sorry about that...newbie here....
Here we go.....what im having trouble doing is inserting this print dialog into my menu
Here is the print snippet
public void print()
        new TimerTestDialog(this);
    class TimerTestDialog extends JDialog
        TimerTestDialog(Frame parent)
            super(parent);
            setLocationRelativeTo(parent);
            setupDialog();
            setModal(false);    // this will allow you to do still stuff with the main frame
                                     //The popup window in this case is not modal. This means that the
                                     //user isnt required to respond to the popup before the program continues running
             * sorry, using a Timer instead of your original TimerTask - it's simpler
            Timer t = new Timer(2000, ticker);
            t.start();
        private void setupDialog()
            Container c = getContentPane();
