How to pick object using QOpenGLWidget

[romzxlat]

Hello,

How to pick and move 3D object using the QOpenGLWidget, right now I can draw only the 3d object. but I don't have any idea to pick and move the object something like drag and drop.

I failed to understand the example in QT.

Thanks and Regards,
Roms
