I was mixing vtkSmartPointer< with (*) initialization.

 

Thank you.

Tks Sankhesh, Dean

 

Just got the problem. I was initializing the with vtkSmartPointer<vtkOrientationMarkerWidget> and my AxesActor  as vtkAxesActor* .

 

Now, both are as following: Worked smoothly

 

vtkAxesActor* viewPortAxActor = vtkAxesActor::New();

              viewPortAxActor->GetXAxisCaptionActor2D()->GetCaptionTextProperty()->SetColor(1, 1, 1);

              viewPortAxActor->SetXAxisLabelText("E");

              viewPortAxActor->GetXAxisCaptionActor2D()->SetWidth(0.05);

              viewPortAxActor->GetXAxisCaptionActor2D()->SetHeight(0.05);

              viewPortAxActor->GetYAxisCaptionActor2D()->GetCaptionTextProperty()->SetColor(1, 1, 1);

              viewPortAxActor->SetYAxisLabelText("N");

              viewPortAxActor->GetYAxisCaptionActor2D()->SetWidth(0.05);

              viewPortAxActor->GetYAxisCaptionActor2D()->SetHeight(0.05);

              viewPortAxActor->GetZAxisCaptionActor2D()->GetCaptionTextProperty()->SetColor(1, 1, 1);

              viewPortAxActor->SetZAxisLabelText("Up");

              viewPortAxActor->GetZAxisCaptionActor2D()->SetWidth(0.05);

              viewPortAxActor->GetZAxisCaptionActor2D()->SetHeight(0.05);

 

              vtkOrientationMarkerWidget* viewPortOMWidget = vtkOrientationMarkerWidget::New();

              viewPortOMWidget->SetOrientationMarker(viewPortAxActor);

              viewPortOMWidget->SetInteractor(mainViewPort->GetInteractor());

              viewPortOMWidget->SetViewport(0.7, 0.0, 1.00, 0.3);

              viewPortOMWidget->SetEnabled(1);

              viewPortOMWidget->InteractiveOn();

Luis,

It seems like you were able to get past the error about interactor not being able to control the event loop using Dean’s suggestion. 

I am not sure why you’re getting OpenGL errors but one thing I noticed is that you are using the OpenGL backend. Would you be able to try the OpenGL2 backend?

Moreover, which version of Qt are you testing against?

Hi Luis,



do not call Start() on the interactor within your Qt programs as Qt

manages its own event loop.

Hello vtkusers,

 

Anybody knows how to use vtkOrientationMarkerWidget with QVTKWidget interactor? I have been trying to implement the VTK example (http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/DisplayCoordinateAxes) and it worked smoothly. However, within  my QVTKWidget Camera, and I caught  the following exception:

 

ERROR: In C:\VTK\VTK-7.0.0\GUISupport\Qt\QVTKInteractor.cxx, line 147

QVTKInteractor (000000F46583D670): QVTKInteractor cannot control the event loop.

 

Following my vtkOrientationMarkerWidget snapshot:

vtkRenderWindow* renwin = vtkRenderWindow::New();

myQVTKWidgetCAmera->SetRenderWindow(renwin);

Ren1 = vtkRenderer::New();

myQVTKWidgetCAmera->GetRenderWindow()->AddRenderer(Ren1);

 

vtkAxesActor* myAxActor = vtkAxesActor::New();

vtkSmartPointer<vtkOrientationMarkerWidget> myWidget = vtkSmartPointer<vtkOrientationMarkerWidget>::New();

              myWidget ->SetOrientationMarker(myAxActor);

              myWidget ->SetInteractor(myQVTKWidgetCAmera->GetRenderWindow()->GetInteractor());

              myWidget ->SetViewport(0.7, 0.0, 1.00, 0.3);

              myWidget ->SetEnabled(1);

              myWidget ->InteractiveOn();

 

Ren1->ResetCamera();

Ren1->Render();

              

myQVTKWidgetCAmera->GetRenderWindow()->GetInteractor()->Start();

 

Thank you very much for any help,
