[vtkusers] Contents of vtk-developers Digest, Vol 146, Issue 17 -RE: [vtk-developers] vtkAxesActor within VTK 7.0 and QVTKWidget

Thu Jun 16 16:40:47 EDT 2016

Hi Sankhesh,

Got this, was missing those two highlighted yellow lines:

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

viewPortOMWidget->SetOrientationMarker(viewPortAxActor);

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

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

              viewPortOMWidget->SetEnabled(1); //missing

              viewPortOMWidget->InteractiveOn();//missing

Thank you,

Hi Luis,

I don't see anything obvious but I noticed that you are initializing vtkRenderingOpenGL i.e. using the OpenGL backend. Mind trying the OpenGL2 backend to find out whether the issue is specific to the old backend.

Hello everyone,

I had migrated my VTK platform from 6.1 to 7.0. I had noticed some changes, and one of those is giving me a hard work to do that is to render  vtkSmartPointer<vtkAxesActor>::New() within QVTWidget. Previously, was easily,  with VTK 6.1. Now, I am trying that and I got the Cone working/rendering well and its interactions. However, I haven't gotten absolutely nothing on my viewport from my vtkAxesActor even been shown . Following my code (C++), regarding that this works outside QVTWidget viewport.

I appreciate any ideas and help.
