I would suggest you study a C++ book more and practice on simple code.

Looking at the original code, can't you just call
 this->Interactor->GetRenderWindow()->Render()
instead of
 this->ui->qvtkWidget->GetRenderWindow()->Render()
You can see just a few lines above, how it gets access to the vtkRenderWindow.

Maybe you should move the addPoint() function to be a member of 
MouseInteractorStylePP instead of SimpleView.
