How to rotate both axes vtkResliceCursorWidget

How to rotate both axes of the reslicecursorwidget together…ie orthogonally It works by using CTRL key as modifier. But i want both axes to rotate together by default without using any modifier key. I tried setting the Setmanipulationmode ;
rep = dynamic_cast<vtkResliceCursorLineRepresentation*>(m_ResliceImageViewerAxial->GetResliceCursorWidget()->GetRepresentation());
rep->SetManipulationMode(vtkResliceCursorLineRepresentation::RotateBothAxes);
but not working.
Can anyone guide me.
