Hello,

I’ve been reading up on Event’s in AS3 today, and… I don’t grasp it completely… Actually I fail pretty bad :crying:. Anyway, is it possible to accomplish event propagation between classes? If it is, say I have a Class called CustomClass and it creates a instance of another Class, CustomSubClass in it, would propagation be possible in such a manner? And if it is, would those custom classes need to extend EventDispatcher or similar?

Thanks for any possible clarification,  
Matt
