[Paraview] Property Panel and Inheritance?

[B.W.H. van Beest]

It seems to work. Inheritance of the vtkCubeSource methods just works.
Also when I reverse the inheritance order, or when I have single
inheritance (of vtkCubeSource), in the xml-file I can just refer to the
methods of the base class vtkCubeSource (say SetLength()) and it works.
But not so for the oher base class!

So I *think* I am using the two baseclasses the same way, the effect
however, is asymmetrial.

I looked, as you suggested,  into sphBoxSourceClientServer.h  The
methods of the baseclasses (vtkCubeSource), e.g. SetXLength(), do not
show-up there either. But it works, so that might not be the place where
to look.

Any other ideas?

Bertwim
