it Works! Thank you Michael!
After having instantiated the elements you suggested, I did for my sagittal
view :
QString sagiText= "F2 : Sagittal View";
m_MeasurementInfoAnnotationSagit->SetText(2, sagiText.toLatin1().data());
mitk::VtkLayerController::GetInstance(sagittaleView->GetRenderer()->GetRenderWindow())->InsertForegroundRenderer(m_MeasurementInfoRendererSagit,
true);
And for volume rendering view I did :
QString treedText= "F1 : 3D View";
m_MeasurementInfoAnnotation3d->SetText(3, treedText.toLatin1().data());
mitk::VtkLayerController::GetInstance(renderWindow3D->GetRenderWindow())->InsertForegroundRenderer(m_MeasurementInfoRenderer3d,
true);
The problem is that now, I'm no longer able to apply rotation to the volume
with the mousse.
Probably because my "m_MeasurementInfoRenderer3d" overlaps the 3d view is
it?
Is there a way to solve that?
Thanks again,
Peter
