[vtkusers] Problem using vtkImagePlaneWidget

[Kevin Keraudren]

Hi,

I believe you are not looking at the right thing.

I do not have an explanation, but I think you should not call 
"Initialize()" or "Start()" yourself, the wx object will take care of it 
himself.

Have a look at the attached code which mixes two examples:
  - 
http://www.doc.ic.ac.uk/project/2011/530/g1153011/builds/vtk/src/VTK/Rendering/Testing/Python/TestMapperLUT.py
  - wxVTKRenderWindowInteractorConeExample() in 
wxVTKRenderWindowInteractor.py

If you leave it as it is, it works. If you uncomment the line 
"widget.Initialize()" you obtain the same crash you described.

Maybe you should try building your application step by step, first 
validating the basic functionalities before putting them all together.

Why don't you write first a working object oriented code with the plane 
widget, then you modify it to have the slice selector, validate it 
before going on with the camera stuff and so on...

Kind regards,

Kevin
