Spinner

Spinner consists of source for classes for a DateSpinner and 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 three 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.
