[Paraview] Property Panel and Inheritance?

[B.W.H. van Beest]

Hi Utkarsh,

Not sure how to do that, really in Paraview. The relationshop and
dynamics between what is in the xml file, source files I write and
generated files by mysterious macros make me still a bit uncomfortable
in finding my way in ParaView.   
Maybe you could a bit more verbose?

Regards,
Bertwim
