SpinnerDateModel, SpinnerListModel, SpinnerNumberModel

public abstract class AbstractSpinnerModel

extends java.lang.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

Method Detail

addChangeListener

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.

Specified by:

addChangeListener in interface SpinnerModel

Parameters:

l - the ChangeListener to add

removeChangeListener(javax.swing.event.ChangeListener), SpinnerModel.addChangeListener(javax.swing.event.ChangeListener)

removeChangeListener

public void removeChangeListener(javax.swing.event.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)

fireStateChanged

protected void fireStateChanged()

Run each ChangeListeners stateChanged() method.

SpinnerModel.setValue(java.lang.Object), EventListenerList

getListeners

public java.util.EventListener[] 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);
 

Parameters:

listenerType - the type of listeners to return, e.g. ChangeListener.class

Returns:

all of the objects receiving listenerType notifications from this model
