I want to select cells in a vtkUnstructuredGrid data, and I created a vtkHardwareSelector for it. And then I found nothing can be selected.
By the way, I test the vtkHardwareSelector with a vtkPolyData, and it works well. 
So, why can't vtkHardwareSelector select cells from vtkUnstructuredGrid? 

Best regards,
