How to get the owner

Question

Hi,
I'm writing an editor in java.
I have written my own textfield class and a popup class.
This editor has autocomplete functionalty (the popup).
On a certain point the popup is requested by the textfield to show itself (popup is declared in the textfield).
At this point the focus goes to the popup. Now i want to popup to set the focus back to the textfield.
Is it possible for the popup to get an instance of the textfield (its creator) and run a method there?
Thanks

Answer 1

Ok, not quite what i need :)
the problem is that the Popup class is created by different classes (AutocompleteTextArea and AutocompleteTextfield).
1 class extends a JTextArea and another class extends a JTextfield
So the class they have in common is JTextComponent.
so what i do is
public class AutocompletePopup extends JFrame {
    private JTextComponent owner;
    private String prefix = "[AutocompletePopup] ";
    public PopupListener listener = new PopupListener();
    private boolean isVisible = false;
    private JScrollPane scroll = new JScrollPane();
    private JList list = new JList();
    private boolean dataIsNull = true;
public AutocompletePopup(JTextComponent owner) {
print("AutocompletePopup() constructor");
this.owner = owner;
this.scroll.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_NEVER);
this.scroll.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
this.setVisible(false);
this.setSize(100, 200);
this.setResizable(false);
this.setUndecorated(true);
this.scroll.setViewportView(list);
list.setVisible(true);
list.setBounds(0, 0, this.getWidth(), this.getHeight());
this.getContentPane().add(scroll);
this.pack();
attachListeners();
}this way i loose the methods from AutocompleteTextArea and AutocompleteTextfield
how can i solve this?
