<div dir="ltr">Hi all.<div><br></div><div>Im trying to ise the igstk::PivotCalibration class. Im using the igstkPivotCalibratioFLTKWidget class as a guideline.</div><div><br></div><div>The problem I have is that I do not receive some calibration events. I get the following events:</div>
<div><br></div><div>igstk::PivotCalibration::InitializationFailureEvent()</div><div>igstk::PivotCalibration::InitializationSuccessEvent()<br></div><div>igstk::PivotCalibration::DataAcquisitionStartEvent()<br></div><div><br>
