[vtkusers] Questions on vtkWindowInteractor and vtkOutputWindow

[Phil Goddard]

I'm new to VTK and am wondering if someone may be able to address the
following questions for me.
Both relate to using the SimpleVTK.java and Cone.java examples.
I'm using the CVS version of VTK, compiling with Visual Studio 2003.Net. 

1. The vtkRenderWindowInteractor seems to be on, however the interactor is
not explicitly set in the code.
Is this interactor on by default?
If so, where is it turned on, and how do I turn it off?
If not, why am I able to use the standard interaction key/mouse movements?

Also, if I only want some of the interactions, is it possible to turn only a
subset of them on/off without writing my own interactor?

2. When I keypress-w I get a vtkOutputWindow being generated and several
warning messages about vtkActor::InitPartTraversal and GetNumberOfParts
being deprecated in VTK5.2
How can I suppress these warnings, and prevent an output window being
created?

Thanks
Phil.
