jspinner

A JSpinner is used to store a number in my application (with a SpinnerNumberModel).

As expected, the spinner doesn't allow invalid characters (letters, symbols, etc.) to be stored. However, those characters do appear in the spinner component when I type them in. As soon as I switch the focus to another component, they disappear.

Is there a way to prevent invalid characters from appearing in the spinner?
