Clip Board Problem

Question

Hey
Thanks for any help i got with the my last problem. I have incoporated the clipboard into the below code. As far as i can gather the code for the clip board is correct as i have it working in simple Jframe and it is working right.
I just cant get it to wotk on the code below, i had other methods in the action preformed, but i've taken them out so its easier to read. If any one can see the problem it would be great. The only error that i am getting is for the dimension size, but it jframe runs fine even with that.
Thanks
Ambrose

Cheers, its just i wanted it to work using the mouse as i do in this simple example below
import java.awt.*;
import java.awt.datatransfer.*;
import java.awt.event.*;
public class ClipTest extends Frame implements
                    ActionListener, ClipboardOwner
     TextField tf = new TextField(20);
     public void actionPerformed(ActionEvent event)
          String cliptext = tf.getText();
          Toolkit tk = this.getToolkit();
          Clipboard cb = tk.getSystemClipboard();
          cb.setContents(new StringSelection(cliptext), this);
     }  //  public void actionPerformed()
     public void lostOwnership(Clipboard cb, Transferable tr) {};
     public static void main(String[] args)
          ClipTest ct = new ClipTest();
          ct.setLayout(new FlowLayout());
          ct.tf.addActionListener(ct);
          ct.add(ct.tf);
          ct.setSize(400, 300);
          ct.setVisible(true);
     }  //  public static void main()
}[\code]
