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.
