QGLBuilder and QGLSceneNode help

fireking

How do I use QGLBuilder and QGLSceneNode to add multiple objects to a scene? When I try the code below app expectedly quits...

QGLBuilder builder;
QGLSceneNode *node;
builder << QGL::Faceted;
builder << QGLSphere(2,4);
root = builder.finalizedSceneNode();
builder << QGLCube();
node = builder.finalizedSceneNode();
root->addNode(node);

Thanks.

...after further reading the following produces a blank screen:
@
CubeView::CubeView(QWindow *parent)
: QGLView(parent)
{
// here a top level node for the app is created, and parented to the view
topNode = new QGLSceneNode(this);

QGLBuilder b1;
// build geometry
b1 << QGL::Faceted;
b1 << QGLSphere(2,4);

thing = b1.finalizedSceneNode();

// does a QObject::setParent() to manage memory, and also adds to the scene
// graph, so no need to call topNode->addNode(thing)
thing->setParent(topNode);

QGLBuilder b2;
// build more geometry
b2 << QGLCube();

anotherThing = b2.finalizedSceneNode();

// again parent on get addNode for free
anotherThing->setParent(topNode);

...working now, changed CubeView::paintGL to only draw child nodes for now...

@
void CubeView::paintGL(QGLPainter *painter)
{
painter->setStandardEffect(QGL::LitMaterial);
painter->setFaceColor(QGL::AllFaces, QColor(170, 202, 0));

painter->modelViewMatrix().rotate(45.0f,1.0f,1.0f,1.0f);
thing->draw(painter);

QMatrix4x4 mat;
mat.translate( 2.0f, 0.0f, -2.0f);
anotherThing->setLocalTransform(mat);
anotherThing->draw(painter);

}
