Hello folks!

In my plugin I use a dedicated interactor called 
"SegmentationInteractor" which derives from DisplayInteractor

You can see below how I load it.

So far, so good, but it looks like the original DisplayInteractor is 
still active because I get two mouse wheel events instead of a single 
one. In consequence, the scroll through planes steps every two instead 
of one.

Changing the active slice through up/down arrow keys works fine (single 
event triggered)

Any clue regarding this misbehavior?

thanks,
sebastian

Here's how I use it:

    us::Module* module = us::GetModuleContext()->GetModule();
     std::vector<us::ModuleResource> resources = 
module->FindResources("/", "*", true);
     for (std::vector<us::ModuleResource>::iterator iter = 
resources.begin(); iter != resources.end(); ++iter)
     {
       MITK_INFO << iter->GetResourcePath();
     }

     m_Interactor = mitk::SegmentationInteractor::New();
     if (!m_Interactor->LoadStateMachine("SegmentationInteraction.xml", 
module))
     {
       MITK_WARN << "Error loading state machine";
     }

     if (!m_Interactor->SetEventConfig ("ConfigSegmentation.xml", module))
     {
       MITK_WARN << "Error loading state machine configuration";
     }

     // Register as listener via micro services
     us::ServiceProperties props;
     props["name"] = std::string("SegmentationInteraction");
     m_ServiceRegistration = 
us::GetModuleContext()->RegisterService<mitk::InteractionEventObserver>( 
m_Interactor.GetPointer(), props);
