[vtk-developers] [Paraview-developers] Moving vtkMemberFunctionCommand to VTK

[Utkarsh Ayachit]

Yes, right now I am requiring the handler is a vtkObjectBase subclass.
Makes it easier to avoid dangling pointers. What do you guys think?
Should we not require it to be a vtkObjectBase? That however means
that user has to be careful about deleting objects that may have a
handler registered.
