Package Summary  Overview Summary

class:DropTargetContext [NONE]
  • All Implemented Interfaces:
    Serializable 
    public class DropTargetContext
extends Object
implements Serializable
    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.

    1.2
