[vtkusers] picker function

[Elena Velasquez]

Hello everyone!

I am using the picker function to select objects, in the case cubes. It seem 
to select the object, yet when I try to retrive the address of the object so 
that I can access some of the properties of the objects, I do not seem to be 
able to get it.
Can anyone help me with this or give me a suggestion?

I select the object using the picker function
then I used the getactor function to try to get the address of the object and 
thereby the properties of the object

Thank you for your help
