Sankhesh,
I believe that the problem doesn’t regard OpenGL backend ,because I succeeded trying this example (http://www.vtk.org/Wiki/VTK/Examples/Cxx/Visualization/DisplayCoordinateAxes).
Actually, I don’t have problems with anything else using VTK 7.0 as well as was backed my OpenGL. I have been setting up the Modules within my application, as following, and worked very well. Also, I am used to with QVTKWidget.
#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL);
VTK_MODULE_INIT(vtkInteractionStyle);
I don’t have problems using for example the following examples. Works smoothly.
vtkSmartPointer<vtkSliderRepresentation2D> sliderRep =
vtkSmartPointer<vtkSliderRepresentation2D>::New();
sliderRep->SetMinimumValue(0.1);
sliderRep->SetMaximumValue(100.0);
sliderRep->SetValue(10.0);
sliderRep->SetTitleText("Size");
sliderRep->GetPoint1Coordinate()->SetCoordinateSystemToDisplay();
sliderRep->GetPoint1Coordinate()->SetValue(100, 100);
sliderRep->GetPoint2Coordinate()->SetCoordinateSystemToDisplay();
sliderRep->GetPoint2Coordinate()->SetValue(300, 100);
vtkSliderWidget *sliderWidget = vtkSliderWidget::New();
sliderWidget->SetInteractor(myQVTKWidgetCamera->GetInteractor());
sliderWidget->SetRepresentation(sliderRep);
sliderWidget->SetAnimationModeToAnimate();
sliderWidget->EnabledOn();
/*****************************************************************************/
vtkTransform* transform = vtkTransform::New();
transform->Translate(1.0, 0.0, 0.0);
vtkAxesActor* viewPortAxActor = vtkAxesActor::New();
// The axes are positioned with a user transform
viewPortAxActor->SetUserTransform(transform);
Ren1->AddViewProp(viewPortAxActor);
Ren1->ResetCamera();

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,
