[Paraview-developers] ParaView XML menu - some queries

[Chiranjib Sur]

Hi Utkarsh,
I am revisiting this section now. I was wondering if you or anybody else in
your team ever considered to give some code snippets in the wiki page? For
example, when I browse the wiki section you have mentioned, it would have
been really helpful if once could browse the code snippet for the
corresponding screenshot (or the pointer to the code snippets from the PV
code base).
Just a suggestions.

Thanks,
Chiranjib
