Base on couse 2, Changed step 4 to

• 4, Create a QVTKOpenGLWidget

  //step 0: set it to a window:
  auto vw = new  QVTKOpenGLWidget(this) ;
  vtkRenderWindow *renWin = vw->GetRenderWindow();
  ui->tabWidget->addTab( vw, __FUNCTION__);
  
  vtkRenderer *render= vtkRenderer::New();
  
  render->SetBackground( 0.1, 0.2, 0.4 );
  
  vtkSmartPointer<vtkConeSource> coneSource = vtkSmartPointer<vtkConeSource>::New();
  coneSource->SetRadius(.2);
  coneSource->SetHeight(.5);
  coneSource->SetCenter(0, 0, 0);
  
  
  vtkSmartPointer<vtkPolyDataMapper> coneMapper =
    vtkSmartPointer<vtkPolyDataMapper>::New();
  coneMapper->SetInputConnection(coneSource->GetOutputPort());
  vtkSmartPointer<vtkActor> coneActor =
    vtkSmartPointer<vtkActor>::New();
  coneActor->SetMapper(coneMapper);
  
  vtkSmartPointer<vtkActor> oriConeActor =
    vtkSmartPointer<vtkActor>::New();
  oriConeActor->SetMapper(coneMapper);
  
  
  // added outline
    vtkSmartPointer<vtkOutlineFilter> outline =
    vtkSmartPointer<vtkOutlineFilter>::New();
    outline->SetInputConnection(coneSource->GetOutputPort());
  
    vtkSmartPointer<vtkPolyDataMapper> outlineMapper =
    vtkSmartPointer<vtkPolyDataMapper>::New();
    outlineMapper->SetInputConnection(outline->GetOutputPort());
  
    vtkSmartPointer<vtkActor> outlineActor =
    vtkSmartPointer<vtkActor>::New();
    outlineActor->SetMapper(outlineMapper);
    outlineActor->GetProperty()->SetColor(0, 0, 0);
  
  
  render->AddActor(oriConeActor);
  render->AddActor(outlineActor);
  renWin->AddRenderer( render );
