QOpenGLWidget and Qt3D for Overlays

[Doug Rogers]

I have a QOpenGLWidget and I would like to draw overlays on top of it using Qt3DCore and Qt3DExtras.
The QOpenGLWidget window works fine and my render code is in the paintGL call, but I would like to render the Qt3D objects int the same window.

For example, how to render this torus into the QOpenGLWidget window during the paintGL call:

// Torus shape data
//! [0]
m_torus = new Qt3DExtras::QTorusMesh();
m_torus->setRadius(1.0f);
m_torus->setMinorRadius(0.4f);
m_torus->setRings(100);
m_torus->setSlices(20);
//! [0]

// TorusMesh Transform
//! [1]
Qt3DCore::QTransform* torusTransform = new Qt3DCore::QTransform();
torusTransform->setScale(2.0f);
torusTransform->setRotation(QQuaternion::fromAxisAndAngle(QVector3D(0.0f, 1.0f, 0.0f), 25.0f));
torusTransform->setTranslation(QVector3D(5.0f, 4.0f, 0.0f));
//! [1]

//! [2]
Qt3DExtras::QPhongMaterial* torusMaterial = new Qt3DExtras::QPhongMaterial();
torusMaterial->setDiffuse(QColor(QRgb(0xbeb32b)));
//! [2]

Is this possible?

Thanks.
