[IGSTK-Users] Pivot Calibration events problems.

[Fabian Torres]

Hi all.

Im trying to ise the igstk::PivotCalibration class. Im using the
igstkPivotCalibratioFLTKWidget class as a guideline.

The problem I have is that I do not receive some calibration events. I get
the following events:

igstk::PivotCalibration::InitializationFailureEvent()
igstk::PivotCalibration::InitializationSuccessEvent()
igstk::PivotCalibration::DataAcquisitionStartEvent()


After the InitializationSuccessEvent I use

                       pivotCalibration->RequestComputeCalibration();

and receive a  DataAcquisitionStartEvent, but after that I do not get any
event. I do not receive
a DataAcquisitionEvent, DataAcquisitionEndEvent, CalibrationSuccessEvent
or CalibrationFailureEvent.

This is my callback function for events

void NeedleCalibration::OnCalibrationEvent( itk::Object * caller, const
itk::EventObject & event )
{

std::cout<<"OnCalibrationEvent"<<std::endl;

if(dynamic_cast< const
    igstk::PivotCalibration::DataAcquisitionStartEvent * > (&event) )
{
std::cout<<"Data Acquisition Started"<<std::endl;
}
else if(dynamic_cast< const
    igstk::PivotCalibration::DataAcquisitionEvent * > (&event) )
       {
                std::cout<<"Data Acquisition"<<std::endl;
       }
else if( dynamic_cast<
  const igstk::PivotCalibration::DataAcquisitionEndEvent * > (&event) )
       {
std::cout<<"Data Acquisition Ended"<<std::endl;
       }
  else if(dynamic_cast<
const igstk::PivotCalibration::CalibrationFailureEvent * > (&event) )
       {
std::cout<<"Calibration failed"<<std::endl;
  }
else if( dynamic_cast<
  const igstk::PivotCalibration::CalibrationSuccessEvent * > (&event) )
      {
std::cout<<"Calibration Succed"<<std::endl;

      }
}

And this are my observers

typedef itk::MemberCommand<NeedleCalibration>   CalibrationObserverType;
this->m_CalibrationObserver = CalibrationObserverType::New();
this->m_CalibrationObserver->SetCallbackFunction(this,
&NeedleCalibration::OnCalibrationEvent );
pivotCalibration->AddObserver(igstk::PivotCalibration::DataAcquisitionStartEvent(),
this->m_CalibrationObserver );
pivotCalibration->AddObserver(igstk::PivotCalibration::DataAcquisitionEvent(),
this->m_CalibrationObserver );
pivotCalibration->AddObserver(igstk::PivotCalibration::DataAcquisitionEndEvent(),this->m_CalibrationObserver
);
pivotCalibration->AddObserver(igstk::PivotCalibration::CalibrationSuccessEvent(),this->m_CalibrationObserver
);
pivotCalibration->AddObserver(igstk::PivotCalibration::CalibrationFailureEvent(),this->m_CalibrationObserver
);

My tracker is in tracking state

Can anyone help me with this problem
Thanks for your time
