[Paraview] Python Programmable Filter: Get Filename of Import filter

[pat marion]

Hi Markus,

You can walk up the filter pipeline from the python programmable
filter like this:


filter = self

while filter.GetInput():
  filter = filter.GetInput().GetProducerPort().GetProducer()

print filter.GetClassName()



This is technique is also discouraged :)  Filters should be self
contained algorithms and that do not make assumptions about their
upstream connections.  But, if it works, it works!
