[vtkusers] Simple Point Picker Question-

[Ryan Smith]

Hi-
I have an application using FLTK and VTK together via
the vtkFlRenderWindowInteractor class.  I have my point picking working
after using the following example
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/PointPicker

My concern is that I am only displaying a 2D image and after enabling
interaction, the camera swings around in 3D when the user picks a point and
distorts my image.  Can I modify the following code to allow point picking
but disable the camera view from moving?  Thanks in advance-

-Ryan


class MouseInteractorStylePP : public vtkInteractorStyleTrackballCamera{
  public:
    static MouseInteractorStylePP* New();
    vtkTypeMacro(MouseInteractorStylePP, vtkInteractorStyleTrackballCamera);

    virtual void OnLeftButtonDown()
    {
      std::cout << "Picking pixel: " <<
this->Interactor->GetEventPosition()[0] << " " <<
this->Interactor->GetEventPosition()[1] << std::endl;

      vtkInteractorStyleTrackballCamera::OnLeftButtonDown();
    }
 };
