                  mil.navy.nps.logger.DNDList

All Implemented Interfaces:

javax.accessibility.Accessible, DNDComponentInterface, java.awt.dnd.DragGestureListener, java.awt.dnd.DragSourceListener, java.awt.dnd.DropTargetListener, java.util.EventListener, java.awt.image.ImageObserver, java.awt.MenuContainer, javax.swing.Scrollable, java.io.Serializable

public class DNDList

extends javax.swing.JList

implements DNDComponentInterface, java.awt.dnd.DropTargetListener, java.awt.dnd.DragSourceListener, java.awt.dnd.DragGestureListener

This is swiped from the java tutorial on drag & drop. It implements a JList as both a source and a target for drag & drop operations.
