[Opensg-users] update a node at run time

[Jiejie Zhu]

Hi,

   I am trying to update the root node. I have create the root NodePtr like:
      NodePtr root = Node::create();
   and set SimpleSceneManager:
      mgr->setRoot(root);
   and then I run my application, there is nothing showed. That is correct.
   Click a button, call things like this:
      root = SceneFileHandler::the().read("data/terrin.wrl");   
   Nothing changed. 
   I have to add an extra function to assign the core:
      NodePtr node = SceneFileHandler::the().read("data/terrin.wrl");   
      beginEditCP(_root);
            _root->setCore(Group::create());
            _root->addChild(node);
          endEditCP(_root);
   That works. 
   Is it possible to simplify this operation?

   Thanks a lot.
