[vtkusers] About using SetInteractorStyle

[Zampini Samuele]

Dear all,

I am trying to use the SetInteractorStyle in order to be able to act on only 1 object.

Actually, I do have to cones and I would like to be able to interact either 1st or 2nd one and not on the both of them.

Could you help?

Thanks a lot,

Samuele

PS: below the code (that's almost like the one you can find in the tutorial)
