public class PeriodicTableView

extends java.awt.Container

implements java.awt.event.ItemListener, java.awt.ItemSelectable

This class is a GUI display of the Periodic Table. The PeriodicTable is the database. The PeriodicTableView implements ItemSelectable so that the component behaves as a list from which a user can select items. The items are instanceof type Element. This is the preferred means by which a user selects an Element from the PeriodicTable. If you want to customize the behaviour, you could subclass this class, or make your own class which uses the PeriodicTable database.
