-/**
- * @class Ext.dd.DragDrop
- * Defines the interface and base operation of items that that can be
- * dragged or can be drop targets. It was designed to be extended, overriding
- * the event handlers for startDrag, onDrag, onDragOver and onDragOut.
- * Up to three html elements can be associated with a DragDrop instance:
- *
- * - linked element: the element that is passed into the constructor.
- * This is the element which defines the boundaries for interaction with
- * other DragDrop objects.
- * - handle element(s): The drag operation only occurs if the element that
- * was clicked matches a handle element. By default this is the linked
- * element, but there are times that you will want only a portion of the
- * linked element to initiate the drag operation, and the setHandleElId()
- * method provides a way to define this.
- * - drag element: this represents the element that would be moved along
- * with the cursor during a drag operation. By default, this is the linked
- * element itself as in {@link Ext.dd.DD}. setDragElId() lets you define
- * a separate element that would be moved, as in {@link Ext.dd.DDProxy}.
- *
- *
- * This class should not be instantiated until the onload event to ensure that
- * the associated elements are available.
- * The following would define a DragDrop obj that would interact with any
- * other DragDrop obj in the "group1" group:
- *
- * dd = new Ext.dd.DragDrop("div1", "group1");
- *
- * Since none of the event handlers have been implemented, nothing would
- * actually happen if you were to run the code above. Normally you would
- * override this class or one of the default implementations, but you can
- * also override the methods you want on an instance of the class...
- *
- * dd.onDragDrop = function(e, id) {
- * alert("dd was dropped on " + id);
- * }
- *
- * @constructor
- * @param {String} id of the element that is linked to this instance
- * @param {String} sGroup the group of related DragDrop objects
