If a SWF file or even a component within it has scrollbars, wouldn't it make sense that if the user is hovered over that area (it's in focus) and uses the mouse wheel, that this movement would automatically translate to the scrollbar moving.

Any ideas how this is done, the events or classes used for this? I'm open to outside components or classes too. I haven't started yet, but I'll do an item renderer because it's easy to give it scrollbar.
