Hi Paul,
Thanks for the reply,

Yes, I had tried a few semi-random things to try to understand
what was happening and inadvertantly included one of them
in my posting. What I should have posted is this:
ref_ptr<Switch> switchnode = new Switch;
string name = node->getName();
switchnode->setName(name);
switchnode->addChild(node);
Group* parent = node->getParent(0);
parent->addChild(switchnode.get());
parent->removeChild(node);

I saved the scenegraph to a file and looked at it.
This is the scene graph before:
Group {
name "mviewConeGroup"
nodeMask 0xffffffff
cullingActive TRUE
num_children 1
Group {
name "multiviewCone1"
nodeMask 0xffffffff
cullingActive TRUE
num_children 1
...
Switch {
name "mviewConeGroup"
nodeMask 0xffffffff
cullingActive TRUE
NewChildDefaultValue 0
ValueList {
0
}
num_children 1
Group {
name "mviewConeGroup_old"
nodeMask 0xffffffff
cullingActive TRUE
}
}
The children of mviewConeGroup (Group2 in the example in my earlier post)
are not under mviewConeGroup_old, as I expected they would be.
Thanks
Jim
