[vtk-developers] vtkArrayExtents (and others) Python wrapping

[David Gobbi]

Hi Eric,

The python wrapping of the vtkArray class was broken by this commit,
which happened while I was on vacation:

http://vtk.org/gitweb?p=VTK.git;a=commit;h=ba442dcd57fe6bf52ef7fb9c21cb842e78e489cd

This commit added the typedefs CoordinateT, DimensionT, and SizeT to
vtkArray and its support classes.  The wrappers do not support
typedefs yet, except for a few like vtkIdType that have been
hard-coded.  You can try doing a checkout before the commit mentioned
above and see how things work.  I didn't have much time to experiment
with these classes.

  David

The object is obtained by calling GetExtents() on a vtkArray, and if I print the array object I can see that the proper extents are there, but I can't figure out how to access them: the only methods on the vtkArrayExtents that seem to be wrapped are Append, Contains, SameShape and ZeroBased, and the object isn't iterable or scriptable. As I started trying out other things like vtkArrayRange and vtkArrayCoordinates, I also had trouble figuring out how to use them from Python.
