Modifier and Type	Method and Description
`void`	`addChangeListener(javax.swing.event.ChangeListener l)` Adds a `ChangeListener`.
`void`	`fireStateChanged()` Notifies all listeners that have registered interest for notification on this event type.
`javax.swing.event.ChangeListener[]`	`getChangeListeners()` Returns an array of all the `ChangeListener`s added with addChangeListener().
`edu.uci.ics.jung.algorithms.layout.Layout<V,E>`	`getGraphLayout()` Returns the current graph layout.
