How to set skin at runtime in Flex 4

I have a bunch of custom controls based on a SkinnableContainer.

When adding the control at design time, I can specify a skin by using the skinClass attribute on the tag.

I need to add some of these elements during runtime, and I can't figure out how to s开发者_C百科pecify the skinClass for my controls.

eg.

var something:CustomThing = new CustomThing();

/* mistery code here to attach the skin ? */

addElement(something);

How do I do this?

Thanks!
