All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.dnd.Autoscroll, 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 TreeView

extends DroppableJTree

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

A JTree-based view of the current subscription hierarchy.

Implements DragSourceListener the event interface for originators of Drag and Drop operations to track the state of the user's gesture, and to provide appropriate "drag over" feedback to the user throughout the Drag and Drop operation.

Implements the DragSourceListener interface that is invoked when a drag initiating gesture is detected.
