[vtkusers] vtkActor ID

[Max]

Hi David,
Thank you for your answer,
Maybe my explanation was too vague,
Suppose I have 2 groups, each has 3 vtkSpheres.
I want to change color of the entire group a when a vtkSphere from group a
is picked
And the same for group b.
So one solution for that is having Id a for every object from group a 
And b for every object from group b and then
When clicked, check the id of the clicked item and change the color of all
objects with the same id 
But how can I attach id?


Thank you,
Max
