[vtkusers] Smart Pointers with Qt with no includes?

[Sensei]

Dear all,

I am trying to use smart pointers in my code, which mixes Qt and VTK. 
I'm afraid I am doing something really dangerous here.

First: I don't use CMake now, I need Xcode, and I can't change this 
specification. This means one thing: qmake will not find VTK headers, so 
I must use forward declarations.

The solutions I've found, for example in using a renderer, is declaring 
a raw pointer:



class vtkRenderer;

class hMainWindow : public QMainWindow
{
     // ...
     vtkRenderer    *renderer3d_;
};




In my code I'm using smart pointers as instructed, except that I need to 
save the pointer for further uses:



void hMainWindow::setupRenderer3D()
{
     // ...
     vtkSmartPointer<vtkRenderer> renderer = 
vtkSmartPointer<vtkRenderer>::New();

     // ...

     renderer3d_ = renderer.GetPointer();
}


It seems that it's working, although since I've found no way of getting 
the reference count of a smart pointer, I assume this is a disaster 
waiting to happen.

I really hate including a lot of headers in my code, and as I said, I'd 
like to avoid mixing Qt and VTK as much as possible.

What do you suggest? Ditching smart pointers in all my code?




Thanks!
