Hi James,

The place you should be looking for examples is:
 http://www.vtk.org/Wiki/VTK/Examples

You need to subclass the interactor style OR create observers, not both.

Here is an example of how to subclass the interactor style:

<http://www.vtk.org/Wiki/VTK/Examples/Interaction/MouseEvents>Here is an
example of how to use an observer:

Good luck!
