[vtkusers] Help with vtkActorCollection (correction !!!)

[Johanna]

Thank you very much for helping me out...

I found the error I think. I had to write 
   $allActors initTraversal
and not 
    allActors initTraversal

I am not used to write in tcl either. I normally use c++. But by changing this line it seems to work with both vtkActorCollection and vtkPropCollection...

 I workin in c++ and I don't know tcl, but try this:
 only:
 set allActors [ren1 GetActors]
 //or
 set allActors [ren1 GetProps]
 $allActors GetNumberOfItems

 Do not use
 vtkActorCollection allActors
 because you in this way create a new actorcollection instead of create only
 a pointer
