[vtkusers] Problem with extending of vtkActor class under Win32

[PETROV Alexey]

Dear vtkusers,

I have problem with extending of vtkActor class under Win32.
I have defined a descendant of vtkActor class, something like -

class MyActor: public vtkActor
{
    ...
}

But I can not render my actor.
Is there any limitation?

Please help
