QTouch3DInputHandler example?

[Tom asso]

How do I modify a datavisualization widget app C++ code to use QTouch3DInputHandler instead of Q3DInputHandler ? I'm adapting the Qt "surface" data visualization C++ widget example to run on Android, not just on the desktop.

Per other examples I configure the "surface" app's Q3DSurface as follows:

SurfaceGraph::SurfaceGraph(Q3DSurface *surface)
    : m_graph(surface)
{
    m_graph->setActiveInputHandler(new QTouch3DInputHandler(m_graph));

(where m_graph points to Q3DSurface)
When run on my Android device the surface graph is displayed, but the app doesn't respond to my touch input, i.e. I cannot rotate, zoom, or select. In fact if I build the same app for the desktop, the app responds to mouse/wheel commands as usual - somehow it seems the QTouch3DInputHandler is not activated?

Same problem exactly here, did you find any solution ?
