Examples of DropTargetContext

ae.java.awt.dnd.DropTargetContext
A DropTargetContext is created whenever the logical cursor associated with a Drag and Drop operation coincides with the visible geometry of a Component associated with a DropTarget. The DropTargetContext provides the mechanism for a potential receiver of a drop operation to both provide the end user with the appropriate drag under feedback, but also to effect the subsequent data transfer if appropriate. @since 1.2
