It is possible to change the **vtkRenderWindowInteractor** interactor style at run time ? I have tried to change it from 2D interactor style to 3D interactor style, and is not working … and I am wonder if it is possible …

I have at the start of the program, on InitialUpdate:

`m_pInteractor->SetInteractorStyle(vtkInteractorStyleImage::New());`

where **m\_pInteractor** is **vtkRenderWindowInteractor** type.

and somewhere, at some button event:

`m_pInteractor->SetInteractorStyle(vtkInteractorStyleTrackballCamera::New());`

but seem that **m\_pInteractor** has the same **vtkInteractorStyleImage** type, not **vtkInteractorStyleTrackballCamera** type.

I am really need this switch … it is possible ? And if there it is, how can I do this switch ?
