Spinner Model Controls - The Definitive Guide to Java Swing - page 501

Creating JSpinner Components
The JSpinner class includes two constructors for initializing the component:

public JSpinner()
JSpinner spinner = new JSpinner();

public JSpinner(SpinnerModel model)
SpinnerModel model = new SpinnerListModel(args);
JSpinner spinner = new JSpinner(model);

You can start with no data model and associate it later with the tracking method of JSpinner .
Alternatively, you can start up the component with a full model, in an implementation of the
SpinnerModel interface, of which three concrete subclasses are available: SpinnerDateModel ,
SpinnerListModel , and SpinnerNumberModel , along with their abstract parent class
AbstractSpinnerModel . If you don't specify a model, the SpinnerNumberModel is used. While the
renderer and editor for the component is a JFormattedTextField , the editing is basically done
through a series of inner classes of JSpinner : DateEditor , ListEditor , and NumberFormat , with
its support class in its parent DefaultEditor .

JSpinner Properties
In addition to creating the JSpinner object, you can certainly reconfigure it, through one of the
nine properties listed in Table 14-1.
