I had another go at the ptolemy.qui.Query class and my previous
modifications, once again based on today's subversion repository. See
link at end of post for downloads.

This post is also in response to Christopher's feedback:

Here are the additional modifications:
- All inner classes of ptolemy.qui.Query are now public and static,
  in case one needs to use, e.g., a QueryActionListener in a package
  outside ptolemy.gui. They all contain a private member "_owner"
  of type ptolemy.gui.Query.

  --> ptolemy.gui.Query.diff

- An additional abstract superclass ptolemy.gui.QueryChooser
  (derived from javax.swing.Box) which enables derived classes to
  call _addPair and _notifyListeners of the ptolemy.gui.Query class,
  even if they're outside the ptolemy.gui package.
  (the QueryInputDialogChooser in the example below is now derived
  from this class)

  --> ptolemy-additional_classes.zip

- Updated example to demonstrate the changes. This time, there are
  no classes in the ptolemy... package hierarchy anymore. The example
  contains a simple actor with a parameter consisting of a text field
  and a button to pop up a dialog for entering a string (which is
  then displayed in the text field).

  --> examples.zip (example classes)
      examples.kar (Kepler archive)

Hopefully, this all makes sense to you... ;-)
