Change style on selected text in TextFlow

Question

Hi,

I try to figure this example out, but it only assume that a TextArea is used. I only got the TextFlow to work with. I've tried to translate it to only use functions from TextFlow, but with no success.

http://blog.flexexamples.com/2009/07/25/exporting-a-textflow-object-in-flex-4/ - (its the second example)

Thanks!
