Class AbstractSpinnerModeljava.lang.Object | +--javax.swing.AbstractSpinnerModel
- All Implemented Interfaces:
- SpinnerModel
- Direct Known Subclasses:
- SpinnerDateModel, SpinnerListModel, SpinnerNumberModel
- public abstract class AbstractSpinnerModel
- extends Object
- implements SpinnerModel
This class provides the ChangeListener part of the SpinnerModel interface that should be suitable for most concrete SpinnerModel implementations. Subclasses must provide an implementation of the minimum, maximum, and value properties and the getNextValue and getPreviousValue methods.
- Since:
- 1.4
- See Also:
- JSpinner, SpinnerModel, SpinnerListModel, SpinnerNumberModel, SpinnerDateModel

Method Detail
addChangeListener
public void addChangeListener(ChangeListener l)
- Adds a ChangeListener to the model's listener list. The ChangeListeners must be notified when the models value changes.
- Specified by:
- addChangeListener in interface SpinnerModel
- Parameters:
- l - the ChangeListener to add
- See Also:
- removeChangeListener(javax.swing.event.ChangeListener), SpinnerModel.addChangeListener(javax.swing.event.ChangeListener)
removeChangeListener
public void removeChangeListener(ChangeListener l)
- Removes a ChangeListener from the model's listener list.
- Specified by:
- removeChangeListener in interface SpinnerModel
- Parameters:
- l - the ChangeListener to remove
- See Also:
- addChangeListener(javax.swing.event.ChangeListener), SpinnerModel.removeChangeListener(javax.swing.event.ChangeListener)
getChangeListeners
public ChangeListener[] getChangeListeners()
- Returns an array of all the ChangeListeners added to this AbstractSpinnerModel with addChangeListener().
- Returns:
- all of the ChangeListeners added or an empty array if no listeners have been added
- Since:
- 1.4
fireStateChanged
protected void fireStateChanged()
- Run each ChangeListeners stateChanged() method.
- See Also:
- SpinnerModel.setValue(java.lang.Object), EventListenerList
getListeners
public EventListener[] getListeners(Class listenerType)
- Return an array of all the listeners of the given type that were added to this model. For example to find all of the ChangeListeners added to this model:
myAbstractSpinnerModel.getListeners(ChangeListener.class);
- Parameters:
- listenerType - the type of listeners to return, e.g. ChangeListener.class
- Returns:
- all of the objects receiving listenerType notifications from this model
