■ Note The SpinnerDateModel does not include any of the time zone-related constants of Calendar .

You cannot scroll through those within a JSpinner via a SpinnerDateModel .

Table 14-3 lists the three properties from the SpinnerModel interface and four specific to
the SpinnerDateModel .

Table 14-3. SpinnerDateModel Properties

Property Name Data Type Access

calendarField int Read-write

date Date Read-only

end Comparable

Read-write

nextValue Object Read-only

previousValue Object Read-only

start Comparable Read-write

value Object Read-only

Typically, the only new property you'll use is for getting the final date, although all that
does is wrap the result of getValue() in the appropriate data type. If you've provided a range of
dates to the constructor, the previous or next values will be null when the current value is at an
edge condition.

SpinnerListModel Class
The SpinnerListModel provides for selection from a list of entries, or at least their string repre-
sentation. This class has three constructors:

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

public SpinnerListModel(List<?> values)
List<String> list = args;
SpinnerModel model = new SpinnerListModel(list);
JSpinner spinner = new JSpinner(model);

public SpinnerListModel(Object[] values)
SpinnerModel model = new SpinnerListModel(args);
JSpinner spinner = new JSpinner(model);
