How to get child actors from the world outliner?

How can I get the child actors of an actor as listed in the world outliner?

I can attach actors by drag-and-dropping an actor over another one in the World Ouliner.
But how can I get the child actors of a parent actor?

The AActor::GetAllChildActors() function does not return anything.

Ok I found out: just call GetAttachedActors()!

Great answer! really cant think of that.
