AbstractSpinnerModel

• java.lang.Object

Fields Summary
private transient ChangeEvent	changeEvent Only one ChangeEvent is needed per model instance since the event's only (read-only) state is the source property. The source of events generated here is always "this".
protected EventListenerList	listenerList The list of ChangeListeners for this model. Subclasses may store their own listeners here.

Methods Summary
public void	addChangeListener(javax.swing.event.ChangeListener l) Adds a ChangeListener to the model's listener list. The ChangeListeners must be notified when the models value changes. param l the ChangeListener to add see #removeChangeListener see SpinnerModel#addChangeListener listenerList.add(ChangeListener.class, l);
protected void	fireStateChanged() Run each ChangeListeners stateChanged() method. see #setValue see EventListenerList Object[] listeners = listenerList.getListenerList(); for (int i = listeners.length - 2; i >= 0; i -=2 ) { if (listeners[i] == ChangeListener.class) { if (changeEvent == null) { changeEvent = new ChangeEvent(this); } ((ChangeListener)listeners[i+1]).stateChanged(changeEvent); } }
public javax.swing.event.ChangeListener[]	getChangeListeners() Returns an array of all the ChangeListeners added to this AbstractSpinnerModel with addChangeListener(). return all of the ChangeListeners added or an empty array if no listeners have been added since 1.4 return (ChangeListener[])listenerList.getListeners( ChangeListener.class);
public T[]	getListeners(java.lang.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); param listenerType the type of listeners to return, e.g. ChangeListener.class return all of the objects receiving listenerType notifications from this model return listenerList.getListeners(listenerType);
public void	removeChangeListener(javax.swing.event.ChangeListener l) Removes a ChangeListener from the model's listener list. param l the ChangeListener to remove see #addChangeListener see SpinnerModel#removeChangeListener listenerList.remove(ChangeListener.class, l);
