| Class | public class BasicNodeRenderer |
| Inheritance | BasicNodeRenderer  NodeRenderer mx.core.UIComponent |
| Implements | IDraggableNodeRenderer, ISelectableNodeRenderer, ITweenableNodeRenderer |
| Subclasses | DefaultNodeRenderer |
The hit area is added automatically in createChildren().
Subclasses need to ensure that DisplayObjects at higher depths don't block
mouse events from reaching the hit area. To do this, use the following
code:
setChildIndex(hitArea_sp, numChildren-1);
To change the way the node renderer responds to user interaction, override the event handler methods.
