[Paraview] Get selection of input in Python programmable filter

[Allan Lyckegaard]

Ok, I think I found a way to do it.

First get the proxy of the filter itself (http://public.kitware.com/pipermail/paraview/2011-November/023336.html <http://public.kitware.com/pipermail/paraview/2011-November/023336.html>):

import paraview.servermanager as sm
proxies = sm.ProxyManager().GetProxiesInGroup("sources").values()
selfProxy = [p for p in proxies if p.GetClientSideObject() is self][0]

Then get the selected points of the proxy’s input like this (http://stackoverflow.com/a/27805049):

proxy = paraview.simple.GetActiveSource()
active_selection = proxy.GetSelectionInput(proxy.Port)
