Pinch zoom on a 3D object in Qml.

[lakshmanGiri]

Hi, I am an amateur to Qt Quick. I have rendered a 3D object by referring to some examples in Qt, especially this particular example. https://doc.qt.io/qt-5/qt3d-wireframe-example.html

3D rendering is working fine.
Mouse events are working fine.

But, I have a touch screen monitor and when I try to zoom in or out using two fingers, I couldn't zoom. I also tried PinchArea and PinchHandler but couldn't get the desired output. I am stuck in this.

Can you please suggest to me how to accomplish this?. Thanks in advance.
