+ * Ext.grid.View GridView} and loads the data object which is passed to a cooperating {@link Ext.dd.DragZone DragZone}'s
+ * methods with the following properties:
+ *
+ * - `copy` : Boolean
+ *
+ *   The value of the GridView's `copy` property, or `true` if the GridView was configured with `allowCopy: true` _and_
+ *   the control key was pressed when the drag operation was begun.
+ *
+ * - `view` : GridView
+ *
+ *   The source GridView from which the drag originated.
+ *
+ * - `ddel` : HtmlElement
+ *
+ *   The drag proxy element which moves with the mouse
+ *
