Devit!

I’m not a huge fan of flash components.  I’ve run into too many instances of incompatibilities between version and components themselves.  However the ScrollPane component is just too useful to pass up.  The thought of having to build my own basic UI components also seems like a waste of time.

This article is being written because the documentation on this component is not spectacular and can be quite ambiguous to the new actionscript programmer. I ran into trouble in the methodology of how ScrollPane wants you to work.

Normally the addChild method is used to embed one MovieClip in another.  That was the method I assumed would work for the scrollpane.  However after getting the error “Error #2006: The supplied index is out of bounds.” I realized that was not how it worked.

To simplify, use:

scrollPaneInstance.source = movieClipContainer;

NOT:

scrollPaneInstance.addChild(movieClipContainer);

Due to the fact I’m not a huge fan of the components that come with Flash I’m wondering if anyone has found any other ScrollPane type components that are lightweight and open source. TweenLite is an example of a lightweight alternative to the built in flash library for tweening.
