[vtkusers] QVTKInteractor?

[Manuel Corrales]

Hello.

I am trying to use this code:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Images/PickPixel

using a QVTKWidget. I am getting a segfault in this line:

*this->Picker->Pick( interactor->GetEventPosition()[0],
interactor->GetEventPosition()[1], 0.0, renderer );*

only change I did to the example code was this:

*
QVTKInteractor::SafeDownCast(this->Viewer->GetRenderWindow()->GetInteractor());
*
*
*
Not sure if this is the correct approach. Attached is my code in case you
want to take a look.

Thanks in advance!
Regards,
Manuel.
