Spinner 1.0 - hex and dollar input for Java JSpinner.

Spinner

Spinner: Spinner consists of source for classes to add hex and formatted dollar input/output for Java JSpinner to your own Java programs. Spinner offers two NumberFormatter classes you can use with a JSpinner. One is HexNumberFormatter which lets your JSpinner range over hex values. The other is DollarNumberFormatter which lets your JSpinner range over dollar values. It works better than JSpinner.NumberEditor with a DecimalFormat String since DollarNumberFormatter displays the $ without requiring it on input. Further, DollarNumberFormatter automatically rounds all values to the nearest penny. The program does nothing on its own other that demonstrate the use of the two classes. The classes are designed to be used in your own programs. Why the double arrow icon? That's what the up/down control on a Java JSpinner looks like.
