All Implemented Interfaces:

ActionListener, FocusListener, ImageObserver, MenuContainer, Serializable, EventListener

public class SpinnerField
extends JComponent
implements ActionListener, FocusListener

Constructor Details

SpinnerField

public SpinnerField()

Creates a new SpinnerField instance containing an IntegerTextField

SpinnerField

public SpinnerField(ValidatedTextField l,
 boolean newVersion)

Parameters:

field - - the ValidatedTextField to use

SpinnerField

public SpinnerField(ValidatedTextField l)

Creates a new SpinnerField containing the given ValidatedTextField

Parameters:

field - - the ValidatedTextField to use

Method Details
