[vtk-developers] proposition: disabling interaction in vtk3DWidgets, API addition

[Andy Cedilnik]

Hi Charl,

This should be relatively easy done, since the way I remember all events
go through one method. I do think this would be a good addition,
especially since sometimes you want to let say rotate data instead of
move 3D widget but you want the widget to stay there.
