[vtkusers] Picking actors in vtkImageViewer2

[Bryn Lloyd]

Hi Jothi,

How are you adding the actor? I do it like this:

   vtkDataSetMapper *mapper = vtkDataSetMapper::New();
   mapper->SetInput(dataset);
   vtkActor *actor = vtkActor::New();
   actor->SetMapper(mapper);
   viewer->GetRenderer()->AddActor(actor);

If I press 'p' when the mouse is pointing to a vtkPolyData dataset, it 
is picked (I see a red bounding box).

Cheers,
Bryn
