Passing parameter between jpanel and jframe

Question

Hi guys,
First time posting, so please be nice! :p
Basically, the problem i'm having:
I have created a JFrame class, which adds some JPanels to itself to start with (basic layout stuff).
This JFrame is created and instantiated in main.java, and just displays the basic stuff that i've added.
On the JFrame are a number of JButtons, and when you click on the JButton each JButton it adds a custom JPanel to the main JFrame. Basically, it provides an easy way to produce a kind of menu system using the JPanels.
The problem i have, is that each time a textbox is clicked inside one of the custom JPanels, i want it to pass the name of the textbox and jpanel back to a method setLastTextBox() in the JFrame class.
I tried:
private void jTextPane1FocusGained(java.awt.event.FocusEvent evt) {
    super.setLastTextBox()
}But super. is not the correct call. I'm sure its something pretty simple but i can't think what it is, and i tried googling it to no avail.
I would be extremely greatful if someone could put me back on the right path!
Thanks,

Hi, Mark
I hope I understood you rihgt.
I think that you should add Focus Listeners to the text boxes, rather than panels and create a method setLastTextBox(String panelName, String textBoxName)
and just write something like that
textField1.addFocusListener(new FocusAdapter(){
            public void focusGained(FocusEvent e) {
                String textFieldName = ((JTextField)e.getSource()).getName();
                String panelName = ((JTextField)e.getSource()).getParent().getName();
                 setLastTextBox(textFieldName, panelName);
        });    that is if you write this code inside your frame class
otherwise you can get to your frame, by calling the method getParent() and checking its class until its not YourFrameClass (or JFrame) and then just cast it and call the method.
I hope I was clear
