[MayaVi-users] vtkRenderingPythonTkWidgets.dll in path,but vtk_test.py can't find it

[Predrag I. <pre...@pt...>]

I use Python 2.2.1 under Windows XP sp1.
MayaVi is version 1.2

After i downloaded DLL's and vtkpython from http://folks.astrian.net/godzilla/,
i started vtk_test.py from MayaVi doc directory.

VTK dll's and vtkpython files are in the path,

sys.path gives ['D:\\Python22\\Tools\\idle', 'D:\\python22', 'D:\\Python22\\Tools',
  'D:\\PYTHON22\\DLLs', 'D:\\PYTHON22\\lib', 'D:\\PYTHON22\\lib\\lib-tk',
    'D:\\PYTHON22\\lib\\site-packages', 'D:\\PYTHON22\\lib\\site-packages\\Numeric'
     ,
     'D:\\PYTHON22\\lib\\site-packages\\PIL,'D:\\PYTHON22\\lib\\site-packages\\VTK'] . <----
     

 I can see that there's vtkRenderingPythonTkWidgets.dll in VTK directory,
 yet vtk_test.py session looks like this:

 What  library is dependent on this one?I tried copying this 'nonexistent' DLL
 to Python's DLL folder,but same result.
 
 Should i download complete VTK?
 In  instalation  guide  on  MayaVi's  home  page,there is a reference to Hybrid
 classes from VTK.Is the problem lack of this classes?
      
 Am i missing something here?
 I'll google some,see what comes up.
 Suggestions etc. are very welcome.
