[IGSTK-Users] Scrolling through DICOM slices

[Patrick Cheng]

Hi Maria,

The call back you are looking for is around line 3431 in Navigator.cxx file.

void Navigator::ResliceImageCallback( const itk::EventObject & event )
{

   if ( 
igstk::NavigatorQuadrantViews::ManualReslicingEvent().CheckEvent(&event))
   {
     igstk::NavigatorQuadrantViews::ManualReslicingEvent *resliceEvent =
     ( igstk::NavigatorQuadrantViews::ManualReslicingEvent *) & event;
     ImageSpatialObjectType::IndexType index = resliceEvent->Get();

     PointType point;
     m_ImageSpatialObject->TransformIndexToPhysicalPoint( index, point );

     const double *data = point.GetVnlVector().data_block();

     m_AxialPlaneSpatialObject->RequestSetCursorPosition( data );
     m_SagittalPlaneSpatialObject->RequestSetCursorPosition( data );
     m_CoronalPlaneSpatialObject->RequestSetCursorPosition( data );
     m_CrossHair->RequestSetCursorPosition( data );
   }
}
