[vtkusers] python wrapping local classes

[Ed Bachta]

Thanks for the suggestion, but that didn't do it...

[ebachta at jackson vtkHistogramColorBar]$ vtkpython
vtk version 4.3.0, vtk source $Revision: 1.1610 $, $Date: 2003/06/23
01:45:05 $
(GMT)
Python 2.2.2 (#1, Feb 24 2003, 19:13:11)
[GCC 3.2.2 20030222 (Red Hat Linux 3.2.2-4)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from vtkpython import *
>>> ren = vtk.vtkRenderer()
>>> hcb = vtk.vtkHistogramColorBar()
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
AttributeError: 'module' object has no attribute 'vtkHistogramColorBar'
>>> from libvtkLocalPython import *
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
ImportError: /usr/local/src/VTK/bin/libvtkLocalPython.so: undefined

Btw, this is what my Local/CMakeLists.txt looks like (before the "common
section" that I pasted in):

SET(KIT Local)
SET(UKIT LOCAL)
SET(KIT_PYTHON_LIBS vtkCommonPython)
SET(KIT_LIBS vtkCommon)
                                                                                
SET( Kit_SRCS
vtkHistogramColorBar.cxx
)
                                                                                
SET(Kit_EXTRA_SRCS)
SET(Kit_EXTRA_CMDS)
SET(Kit_TCL_EXTRA_SRCS)
SET(Kit_PYTHON_EXTRA_SRCS)
SET(Kit_JAVA_EXTRA_SRCS)
