addPropertyChangeListener

public void addPropertyChangeListener(PropertyChangeListener listener)

Adds a PropertyChangeListener to the listener list. The listener is registered for all bound properties of this class.

If listener is null, no exception is thrown and no action is performed.

Parameters:

listener - the property change listener to be added

Since:

1.6

removePropertyChangeListener(java.beans.PropertyChangeListener), getPropertyChangeListeners()

removePropertyChangeListener

public void removePropertyChangeListener(PropertyChangeListener listener)

Removes a PropertyChangeListener from the listener list.

If listener is null, no exception is thrown and no action is performed.

Parameters:

listener - the PropertyChangeListener to be removed

Since:

1.6

addPropertyChangeListener(java.beans.PropertyChangeListener), getPropertyChangeListeners()

getPropertyChangeListeners

public PropertyChangeListener[] getPropertyChangeListeners()

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

Returns:

all of this component's PropertyChangeListeners or an empty array if no property change listeners are currently registered

Since:
