public class AdventNetTreeDropSource

extends java.lang.Object

implements java.awt.dnd.DropTargetListener

The class AdventNetTreeDragSource handles the Dropping process of the TreeNode in the ProAdventNetTree.

During the Dragging process a Transferable object is created, so that all the reference of the Dragged TreeNode is converted to DataFlavours using the ConvertTreePathToTransferable() class .

From this Transferable Object the data flavours are retained back to the TreeNode object and after proper validational process the drop is allowed to add as TreeNode in the ProAdventNeTree.
