[vtkusers] Python wrapped custom classes missing inherited methods

[David Gobbi]

Hi Eric,

I can guess what might have caused it.  Yesterday I added some extra
checks to handle rare VTK classes that use multiple inheritance, to
make sure that non-vtkObjectBase superclasses are rejected.  My guess
is the wrappers aren't recognizing the superclass for wrapped custom
classes.

Please send me the generated Python.cxx file for your class by private
email, I should be able to sort out the problem fairly quickly.

   David

An example would be the vtkImageFoo class, which inherits from vtkThreadedImageAlgorithm: I only get the methods defined in vtkImageFoo.h, and not all the ones from its parent class. So, things like SetNumberOfThreads() and SplitExtent() are missing, while SetFoo() is there. All of the "standard" classes inheriting from vtkThreadedImageAlgorithm look fine (e.g. vtkImageAppend still has SetNumberOfThreads()).
