Doug,
I realize that my derived class would probably not have access to
protected members of the Group class since I am not in the same package.
Otherwise, could I get some guidance concerning the best way to perform
the reordering?
For example, should I place the whole OrderedGroup in a BranchGroup,
detach it, reorder my nodes, then reattach?
Also, I noticed in the API that only BranchGroups can be added/set in a
Group when it is live/compiled. Well, if I detach the OrderedGroup, is
it then considered to not be live? I think my problem is that at the
top of the scene graph I perform a compile, so the OrderedGroup gets
compiled. Is there any way to tell the OrderedGroup to not be compiled?
Can you tell I'm still desperate? ;)
