The DragEvent class is used in the dispatching of the two events associated with drag and dropping. With general use of the tree and its drag and drop capabilities, you will not need to use or reference this class. However, if you implement your own drag and drop logic, you will need to import and use this class. It provides a single additional property, dragItem, which is the DragItem instance containing data about the item being dragged.
| Property Name | Class | Value | Description |
| DRAG | String | "dragItem" | Event dispatched when the mouse moves while dragging an item. |
| DROP | String | "dropItem" | Event dispatched when a dragged item is dropped. |
