[IGSTK-Users] Pivot Calibration events problems.

[Özgür Güler]

Hi Fabian,
your callback function is not complete. The "if" and "else if" statements
do not check for a certain event invoked. Use code above as template:

  if( const igstk::PivotCalibration::DataAcquisitionEvent *evt =
     dynamic_cast< const igstk::PivotCalibration::DataAcquisitionEvent * >
(&event) )
  {
// set progress bar
  }
  else if( dynamic_cast<
          const igstk::PivotCalibration::DataAcquisitionEndEvent * >
(&event) )
  {
// do nothing
  }
  else if( const igstk::PivotCalibration::CalibrationFailureEvent *evt =
       dynamic_cast<
          const igstk::PivotCalibration::CalibrationFailureEvent * >
(&event) )
  {
 // handle error
  }
 else if( dynamic_cast<
          const igstk::PivotCalibration::CalibrationSuccessEvent * >
(&event) )
  {
// process results
}

Best,
Ozgur
