[vtkusers] How to get a vtkContextView into a QWidget?

[da]

Thanks Eric.

I ended up doing something like this

vtkSmartPointer<QVTKInteractor> renderWindowInteractor =
vtkSmartPointer<QVTKInteractor>::New();
renderWindowInteractor->SetRenderWindow(*(vtkContextView)*
->GetRenderWindow());
renderWindowInteractor->Initialize();

*(QVTKWidget)*->SetRenderWindow(*(vtkContextView)*->GetRenderWindow());

since QVTKWidget requires a QVTKInteractor as the Interactor. I created a
new QVTKInteractor, attached it as vtkContextView's interactor, and then
just set the renderwindow from context view into the qvtkwidget.

(BTW, thanks to the guys developing the new chart classes, they look very
nice! Especially in Paraview!)
