     According to

http://docs.oracle.com/javase/tutorial/uiswing/components/spinner.html

     "... if you implement a spinner model that does not descend from
     SpinnerListModel, SpinnerNumberModel, or SpinnerDateModel, then the
     spinner's default editor is a non-editable instance of
     JSpinner.DefaultEditor."

So it appears you have a couple of possibilities.  One, you could use a
custom model, or two, you could set a custom editor (possibly just a
raw JSpinner.DefaultEditor instance).  Good luck!

Thanks for that!

I found an even simpler answer:

((JSpinner.DefaultEditor)spinner.getEditor()).getTextField().setEditable(false);

Not sure how I missed it on the first two passes through the docs but 
JSpinner.DefaultEditor uses a JFormattedTextField as the editor window.

The only risk I see to this approach is if O changes the text field that 
the editor uses for my specific JSpinner.???Editor. Probably a pretty 
low risk.
