[Paraview-developers] Filtered choice of attributes

[Cornelis Bockemühl]

Thanks for this! And not the least also for the quick reaction you are
showing to so many questions here!!

But how do I integrate such a subclass into Paraview so that it replaces
the original class: Do I have to recompile Paraview for this (ok, can be
done - did it already...) or is there a way to "insert" this code like with
the plugins?

Kind regards, Cornelis
