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

[Utkarsh Ayachit]

Attached another patch which keeps the same API, but that compiles :).

Sample usage:

class vtkSomeClass : public vtkObject
{
public:
  ....
   void OnEvent()
    {
    cout << "Callback invoked" << endl;
    }
};

int TestObserver()
{

   object->AddObserver<A>(vtkCommand::AnyEvent,
    object, &A::Callback);
  object->InvokeEvent(vtkCommand::ModifiedEvent);
  object->Delete();
}
