Hi,

I am rather new to VTK and I am currently
working on a molecular visualization programm.

I am able to visualize the molecule using spheres
and cylinders, pick spheres (atoms)
in my scene and change their color (or other properties).

Now I would like to get the position of the picked object
in the loop used to create these objects. More precisely,
I would like to get the value of "i" (see the example below) 
corresponding to the selected object so that I can use
list[i] (list is a vector and len(list) is its length)
