public class DnDList<T>
A sub-class of JList that supports drag and drop to reorder items within a single list and to copy or move items between lists. It is used by the MapLayerTable widget but has been written in a general fashion so that it may be used for other pusposes.

public void dragGestureRecognized(java.awt.dnd.DragGestureEvent dge)
dragGestureRecognized
in interface java.awt.dnd.DragGestureListener
public void dragEnter(java.awt.dnd.DragSourceDragEvent dsde)
Description copied from interface:
Called as the cursor's hotspot enters a platform-dependent drop site.
This method is invoked when all the following conditions are true:
dragEnter
in interface java.awt.dnd.DragSourceListener
public void dragOver(java.awt.dnd.DragSourceDragEvent dsde)
Description copied from interface:
Called as the cursor's hotspot moves over a platform-dependent drop site.
This method is invoked when all the following conditions are true:
dragOver
in interface java.awt.dnd.DragSourceListener
public void dropActionChanged(java.awt.dnd.DragSourceDragEvent dsde)
Description copied from interface:
Called when the user has modified the drop gesture. This method is invoked when
the state of the input device(s) that the user is interacting with changes.
Such devices are typically the mouse buttons or keyboard modifiers that the
user is interacting with.

public void dragExit(java.awt.dnd.DragSourceEvent dse)
Description copied from interface:
Called as the cursor's hotspot exits a platform-dependent drop site.
This method is invoked when any of the following conditions are true:

Called while a drag operation is ongoing, when the mouse pointer enters
the operable part of the drop site for the DropTarget registered with
this listener.

public void dragOver(java.awt.dnd.DropTargetDragEvent dtde)
Description copied from interface:
Called when a drag operation is ongoing, while the mouse pointer is still
over the operable part of the drop site for the DropTarget registered with
this listener.

public void drop(java.awt.dnd.DropTargetDropEvent dtde)
This method is responsible for undertaking the transfer of the data associated with the gesture. The DropTargetDropEvent provides a means to obtain a Transferable object that represents the data object(s) to be transfered.
From this method, the DropTargetListener shall accept or reject the drop via the acceptDrop(int dropAction) or rejectDrop() methods of the DropTargetDropEvent parameter.
Subsequent to acceptDrop(), but not before, DropTargetDropEvent's getTransferable() method may be invoked, and data transfer may be performed via the returned Transferable's getTransferData() method.
At the completion of a drop, an implementation of this method is required to signal the success/failure of the drop by passing an appropriate boolean to the DropTargetDropEvent's dropComplete(boolean success) method.
Note: The data transfer should be completed before the call to the DropTargetDropEvent's dropComplete(boolean success) method. After that, a call to the getTransferData() method of the Transferable returned by DropTargetDropEvent.getTransferable() is guaranteed to succeed only if the data transfer is local; that is, only if DropTargetDropEvent.isLocalTransfer() returns true. Otherwise, the behavior of the call is implementation-dependent.
