hm, that's confusing. That's pretty exactly what addChild does
internally anyway:
void Node::addChild(const NodePtr &childP)
{
...
// already somebody else's child?
if(childP->getParent() != NullFC)
{
beginEditCP(childP->getParent(), Node::ChildrenFieldMask);
childP->getParent()->subChild(childP);
endEditCP(childP->getParent(), Node::ChildrenFieldMask);
}
_mfChildren.push_back(childP);
beginEditCP(childP, Node::ParentFieldMask);
{
childP->setParent(getPtr());
}
endEditCP (childP, Node::ParentFieldMask);
...
}
I'm a little lost, anybody else have an idea?
