public class ListDataSource

extends ColumnModelSupport

implements javax.swing.event.ListSelectionListener, java.beans.PropertyChangeListener

ListDataSource provides a JFC's ListModel implementation which gets its items from a infobus ScrollableRowsetAccess.

ListDataSource binds itself to the given column in a ScrollableRowsetAccess dataItem and provides a read-only access to all the column values.

ListDataSource works with a JList. It listens on the JList's selection model and keeps the list selection and ScrollableRowsetAccess currency in sync.
