                               boolean newAdjusting)

Specified by:

setRangeProperties in interface BoundedRangeModel

propertyChange

public void propertyChange(PropertyChangeEvent evt)

Specified by:

propertyChange in interface PropertyChangeListener

addChangeListener

public void addChangeListener(ChangeListener l)

Adds a ChangeListener. The change listeners are run each time any one of the Bounded Range model properties changes.

Specified by:

addChangeListener in interface BoundedRangeModel

Parameters:

l - the ChangeListener to add

See Also:

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

removeChangeListener

public void removeChangeListener(ChangeListener l)

Removes a ChangeListener.

Specified by:

removeChangeListener in interface BoundedRangeModel

Parameters:

l - the ChangeListener to remove

See Also:

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

getChangeListeners

public ChangeListener[] getChangeListeners()

Returns an array of all the change listeners registered on this DefaultBoundedRangeModel.

Returns:

all of this model's ChangeListeners or an empty array if no change listeners are currently registered

Since:

1.4

See Also:

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

fireStateChanged

protected void fireStateChanged()

Runs each ChangeListener's stateChanged method.

See Also:

setRangeProperties(int, int, int, int, boolean), EventListenerList

toString

public String toString()

Returns a string that displays all of the BoundedRangeModel properties.

Overrides:

toString in class Object

getListeners

public <T extends EventListener> T[] getListeners(Class<T> listenerType)

Returns an array of all the objects currently registered as FooListeners upon this model. FooListeners are registered using the addFooListener method.

You can specify the listenerType argument with a class literal, such as FooListener.class. For example, you can query a DefaultBoundedRangeModel instance m for its change listeners with the following code:

ChangeListener[] cls = (ChangeListener[])(m.getListeners(ChangeListener.class));

If no such listeners exist, this method returns an empty array.

Parameters:

listenerType - the type of listeners requested; this parameter should specify an interface that descends from java.util.EventListener

Returns:

an array of all objects registered as FooListeners on this model, or an empty array if no such listeners have been added

Throws:

ClassCastException - if listenerType doesn't specify a class or interface that implements java.util.EventListener

Since:

1.3
