[vtkusers] ResetCamera() via 'r' Key - disable or manipulate?

[reppesis at gmail.com]

I semi-solved this by doing the following, but as you suspected: Some weird
stuff happens when holding the 'r' key.

renderer.AddObserver("ResetCameraEvent", PostResetCamera)
def PostResetCamera(obj, event):
    active_camera = obj.GetActiveCamera()
    active_camera.Zoom(1.3)

So after all I'd love to override OnChar() but I can't adapt the example
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Interaction/KeypressEvents to
Python.


class MyInteractorStyle(vtkInteractorStyleTrackballCamera):
    def OnKeyPress(self):
        print "hallo"

doesn't do anything at all, those macros don't seem to exist :S
