AS3 Content Scroller

Scroller is a lightweight, easy to use and customize vertical scrollbar for Actionscript 3 that can smoothly scroll any DisplayObject (MovieClip, Sprite, Textfield, etc) with minimal coding needed. The Scroller can be easily skinned to match your existing projects, and for more advanced programmers can be customized to scroll your content exactly as you wish, either dynamically or drag and drop.

The Scroller can make use of the mouse wheel for scrolling, mask the scroll content on the fly or use user specified masks, and resize the handle of scroller to represent the amount of scrolling available.

Scroller is ideal for Flash users with basic and advanced knowledge of Actionscript 3 who wish to quickly and easily re-use a vertical scrollbar on all their projects without having to edit loads of code and edit clumsily created MovieClips to skin the scroller.

Update

It is important when using a dynamically populated textfield to set this field to auto size, eg: textfield_txt.autoSize = "left";
