Getting my head around DocumentListener and how inner classes work

Question

So I'm trying to get my first Swing GUI up and running and I cannot get my head around the DocumentListener.
I have a JTextArea element called textArea which has the following code for it's listener:
public class Gui extends JFrame {
    public Gui() {
        // Add the Text area
        JTextArea textArea = new JTextArea(textDoc);
        add(scrollPane, BorderLayout.CENTER);
        textArea.getDocument().addDocumentListener(new DocumentListener() {
            public void changeUpdate(DocumentEvent e) {
            public void insertUpdate(DocumentEvent e) {
                saveText();
            public void removeUpdate(DocumentEvent e) {
            public void changedUpdate(DocumentEvent e) {
                throw new UnsupportedOperationException("Not supported yet.");
    public void saveText() {
        System.out.println("saving");
}Now of course this will not work. The method saveText() is in the parent class. So how do I invoke this method???
Instead of calling the saveText() method I could interact with the variables of the parent class so why can't I invoke the method?

Anyway, if there actually were a conflict (there isn't here, that's not why it's not working) you can always qualify the member further:
//for instance member
Gui.this.saveText();
//for static member
Gui.otherMethod();
