public class JSpinField extends JPanel implements ChangeListener, CaretListener, ActionListener, FocusListener
JSpinField is a numeric field with 2 spin buttons to increase or decrease the value. It has the same interface as the "old" JSpinField but uses a JSpinner internally (since J2SE SDK 1.4) rather than a scrollbar for emulating the spin buttons.
