[vtkusers] vtkQtGraphicsViewRenderWindow

[Doug Hoppes]

Yeah, I saw the example.  Is one method more efficient than the other one? 

The current idea that I'm using is that, in my QT application, I have a VTKView class that is sub-classed from QGraphicsView. Inside this class, I create an instance of the QVTKWidget2 (just like the example). 

I DO like the idea of just adding QVTKGraphicsItem to my scene. If the user resizes the window, wouldn't I need to resize the graphics Item (so that it fully takes up my window)?

You can also have a look at the code in VTK/Examples/GUI/Qt/GraphicsView.
It uses QVTKWidget2 instead of QVTKWidget as the viewport widget in a QGraphicsView.

There is also a QVTKGraphicsItem class if you want a VTK window as an item in the QGraphicsView.
