Just iterate through the CRefArray and check each members for siFxTreeID
ClassID..
ahhh - I'd looked at that, but thought it might have efficiency
issues. Hmmm actually that just made me realise - it's only giving the
objects directly under the scene root. FXTrees could be anywhere in
the hierarchy - scanning recursively through the entire scene sounds
bad....
any ideas on a nice way to do it?
I gather I'll still need to use the CComAPIHandler to deal with the
FXTree nodes once I've got them?
Cheers,
Alan.
