[vtkusers] vtkImageViewer2 trouble with QVTKWidget

[Antonin Perrot-Audet]

Hello,
I have some trouble using the QVTKWidget with a vtkImageViewer2 :
I am able to render an image in the QVTKWidget, but if I try to setup an 
interactor, the application freezes :
--------
   
vtkImgViewer2->SetupInteractor(this->qvtkWidget_a->GetRenderWindow()->GetInteractor());
--------
I have seen several mails about using vtkImageViewer2 and QT, even from 
Luis, but there seems to be no solution yet ?
Should I use a vtkImageViewer instead ?

Here is a short version of my code : vtkImage is a pointer towards a 
vtkImageData, given as an argument
--------
vtkSmartPointer<vtkImageViewer2> vtkImgViewer2 = 
vtkSmartPointer<vtkImageViewer2>::New();
vtkImgViewer2->SetInput(vtkImage);
vtkImgViewer2->Render();
   // makes the program crash :
   
//vtkImgViewer2->SetupInteractor(this->qvtkWidget_a->GetRenderWindow()->GetInteractor());
this->qvtkWidget_a->SetRenderWindow(vtkImgViewer2->GetRenderWindow());
--------

So that I now have the weird behavior that I can display an image and 
interact with it as a 3D object ....

The vtkImageData seems to be provided just fine as I can display the 
image with the wrong interactor, so it doesn't seem to be a pipeline 
problem ?
I also tried declaring an interactor of vtkImageInteractorStyle, and 
attributing it to both the vtkImageViewer2 and the QVTKWidget, with the 
same results.

*any idea or even experience using these tools would be greatly 
appreciated,*

Thanks,

Antonin
