Please describe what is not working. Please include your version of wxVTK.

Yup, you are using VTK 5.x alright. Take any example using the Tcl RWI
(on UNIX) from VTK official, you'll be able to reproduce that.
I think VTK 5.0 should not produce this warning.

When the API was upgraded, a bug was introduced. But I suspect no one
saw it, as most people use another interactor style. Try the trackball
one (press 't').

Absolutely not ! Trust me, and I know the main author of wxVTK (but
don't tell him that).

Ok seriously, I don't mean to be offended here, but at least describe
your issues here. It is not perfect (wxVTK does not work with latest
wxwidget 2.8.x) but I did work hard to get it working in the wx 2.4.x
branch. 2.6.x should be ok on linux/win32.
As a side note you could have gotten a tons more answers on the wxVTK
mailing list, where you'll find the most heavy users of this class:
