void	addNotify() Called when the node list is to be active.
List<K>	keys() Obtains child keys which will be passed to node(K).
Node	node(K key) Creates a node for a given key.
void	removeChangeListener(ChangeListener l) Removes a change listener.
void	removeNotify() Called when the node list is no longer needed.

Method Detail

keys

List<K> keys()

Obtains child keys which will be passed to node(K). If there is a change in the set of keys based on external events, fire a ChangeEvent.

Returns:

list of zero or more keys to display

addChangeListener

void addChangeListener(ChangeListener l)

Adds a listener to a change in keys.

Parameters:

l - a listener to add

removeChangeListener

void removeChangeListener(ChangeListener l)

Removes a change listener.

Parameters:

l - a listener to remove

node

Node node(K key)

Creates a node for a given key.

Parameters:

key - a key which was included in keys()

Returns:

a node which should represent that key visually or null if no such node can be created currently.

addNotify

void addNotify()

Called when the node list is to be active. Equivalent to Children.addNotify(). If there is any need to register listeners or begin caching of state, do it here.

Children.addNotify()

removeNotify

void removeNotify()

Called when the node list is no longer needed. Equivalent to Children.removeNotify(). Unregister any listeners and perform any general cleanup.
