Member Function Documentation

void FWInteractionList::added	(	TEveElement *	el,
		unsigned int	idx
	)

This function is called from FWProxyBuilderBase::build() function (e.g. on next event). The PB build function creates TEveElement for each element of collection and calls this function to add the element to "master" element, which is a TEveCompound.
