[vtkusers] vtkImageViewer2 and QVTKWidget

[Marcos]

Still having the problem, trying to simplify:

con->SetInput(modelo->getImageToSave());

con->Update();


imageData->DeepCopy(con->GetOutput());


imageViewer->SetInputData(con->GetOutput());

imageViewer->GetRenderer()->ResetCamera();

imageViewer->Render();


ui->qvtkwidget->SetRenderWindow(imageViewer->GetRenderWindow());

ui->qvtkwidget->GetRenderWindow()->SetInteractor(imageViewer->GetRenderWindow()->GetInteractor());


ui->qvtkwidget->update();



I'll keep on trying.

I would appreciate any help on this.
