JFileChooser as a panel, not as a dialog

Question

I'm trying to use a JFileChooser as a panel in a wizard.
I can get the selected file name back if the user double-clicks by adding an ActionListener onto the chooser.
I can get the selected file name back if the user single-clicks by adding a PropertyChangeListener (prop = SelectedFileChangedProperty).
However, if the user enters a name by typing it (or pasting it I guess), when I call getSelectedFile(), it returns the wrong value.
So, I need to know how to read the value that's in the text field, or get an event when the user changes it, or make the field un-editable.
I've searched the forums for quite a while, but have not found any applicable topics. Can this be done? Thanks...

Answer 1

I was able to get the value from that text by extending JFileChooser, and adding this recursive method:
   public String getEnteredFile (Component c)
      if (c instanceof JTextField)
         return ((JTextField) c).getText();
      if (c instanceof Container)
         for (Component child : ((Container) c).getComponents())
            String text = getEnteredFile (child);
            if (text != null)
               return text;
      return null;
However, I still can't tell if the user has entered data into that field, so that I can enable my wizard's Next button. I guess I can use a similar recursive method to get the JTextField, and add a listener on it. Seems kind of clunky, but it should work...
