Strange... that works for me too. What isn't working is that same code but
using a QVTKWidget that is on a form made in the Qt Designer (so
instantiated from a .ui file).


  vtkSmartPointer<vtkRenderer> rightRenderer =
      vtkSmartPointer<vtkRenderer>::New();

  // Add Actor to renderer
  rightRenderer->AddActor(cubeActor);

  // VTK/Qt wedded
  this->ui->qvtkWidgetRight->GetRenderWindow()->AddRenderer(rightRenderer);

  //add a border widget to the right renderer
  vtkSmartPointer<vtkBorderWidget> borderWidget =
      vtkSmartPointer<vtkBorderWidget>::New();
  borderWidget->SetInteractor(this->ui->qvtkWidgetRight->GetInteractor());
  borderWidget->On();

The cube shows up, so the renderer is setup correctly, but still no border
widget ??

Here is the complete example:

Maybe there is something wrong with the .ui file? It seems like everything
is ok though since it compiles and I can interact with the cube...

Thanks,

David
