public interface: SpinnerModel [javadoc | source]

All Known Implementing Classes:
    SpinnerListModel, SpinnerDateModel, AbstractSpinnerModel, SpinnerNumberModel

A model for a potentially unbounded sequence of object values. This model is similar to ListModel however there are some important differences:

A SpinnerModel has three properties, only the first is read/write.

value
The current element of the sequence.
nextValue
The following element or null if value is the last element of the sequence.
previousValue
The preceeding element or null if value is the first element of the sequence.
When the the value property changes, ChangeListeners are notified. SpinnerModel may choose to notify the ChangeListeners under other circumstances.
Method from javax.swing.SpinnerModel Summary:
addChangeListener,   getNextValue,   getPreviousValue,   getValue,   removeChangeListener,   setValue
Method from javax.swing.SpinnerModel Detail:
 public  void addChangeListener(ChangeListener l)
    Adds a ChangeListener to the model's listener list. The ChangeListeners must be notified when models value changes.
 public Object getNextValue()
    Return the object in the sequence that comes after the object returned by getValue(). If the end of the sequence has been reached then return null. Calling this method does not effect value.
 public Object getPreviousValue()
    Return the object in the sequence that comes before the object returned by getValue(). If the end of the sequence has been reached then return null. Calling this method does not effect value.
 public Object getValue()
    The current element of the sequence. This element is usually displayed by the editor part of a JSpinner.
 public  void removeChangeListener(ChangeListener l)
    Removes a ChangeListener from the model's listener list.
 public  void setValue(Object value)
    Changes current value of the model, typically this value is displayed by the editor part of a JSpinner. If the SpinnerModel implementation doesn't support the specified value then an IllegalArgumentException is thrown. For example a SpinnerModel for numbers might only support values that are integer multiples of ten. In that case, model.setValue(new Number(11)) would throw an exception.
