Click a button, call things like this:
root = SceneFileHandler::the().read("data/terrin.wrl");
Nothing changed.

NodePtr root = Node::create();

The SceneFileHandler creates a new Node (containing the loaded scene) which
you assign here to the variable root. The SimpleSceneManager doesn't know
about this new Node. That's why nothing is displayed.
Your solution (creating a Group core) is OK but you asked for a simpler way.
Just tell the SimpleSceneManager about the new root node. :)

NodePtr root = SceneFileHandler::the().read("data/terrin.wrl");

Hope it helps,
