[vtkusers] the sphere not be dsiplayed with the vvtkboxwidget

[Eric E. Monson]

Hey Ali,

You need to uncomment the line:

  renderer->AddActor(actor);

and then add a line after the vtkBoxRepresentation is created:

  boxRepresentation->PlaceWidget(sphereSource->GetOutput()->GetBounds());

Take a look at the BoxWidget2 test code (linked from the vtkBoxWidget2 doxygen page: http://www.vtk.org/doc/nightly/html/classvtkBoxRepresentation.html) to see how to link the box to a transform of the sphere:
