Hi Pat,
thank you for the fast help! As mentioned I am still beginner with ParaView and
do not know all the insights from ParaView. Furthermore I have to say that at
the moment (we are just beginning to use ParaView) both the server and the
client do run on the same machine (but in the future we as well like to run it
on seperate machines)
First of all I have to say that the provided solution does not work as it was
written here. It terminates with the following error:
Traceback (most recent call last):
File "<string>", line 26, in <module>
File "<string>", line 4, in RequestData
File "C:\Program Files (x86)\ParaView
3.12.0\lib\paraview-3.12\site-packages\paraview\servermanager.py", line 1502,
in GetProxiesInGroup
for aProxy in iter:
File "C:\Program Files (x86)\ParaView
3.12.0\lib\paraview-3.12\site-packages\paraview\servermanager.py", line 1706,
in next
self.AProxy = _getPyProxy(self.SMIterator.GetProxy())
File "C:\Program Files (x86)\ParaView
3.12.0\lib\paraview-3.12\site-packages\paraview\servermanager.py", line 2227,
in _getPyProxy
classForProxy = _findClassForProxy(_make_name_valid(xmlName),
smproxy.GetXMLGroup())
File "C:\Program Files (x86)\ParaView
3.12.0\lib\paraview-3.12\site-packages\paraview\servermanager.py", line 2289,
in _findClassForProxy
return filters.__dict__[xmlName]
NameError: global name 'filters' is not defined
Dealing a bit more with the python interface I found out, that Proxy is not the
correct thing I really need - I believe that I rather would need the filter.
To understand what I want to do:
-) the user loads a file series of vtu or inp files
-) then he can should apply the python programmable filter
This filter should then open a txt file (which will always be placed in the
same directory as the vtu/inp files).
The filter will then parse the txt file and according to the actual inp/vtu
file in the file series it will read a certain value from this text file. This
value will be used as x value whereas the y value is calculated by using
several vtk filters in the python programmable filter (calculating the y value
does already work properly).
In order to automatically open this txt file I would need the directory from
the first (input) filter. Furthermore I want to get the recent inp/vtu file
name of the file series in order to get the correct information (=row) out of
the txt file.
Perhaps somebody has another idea in order resolve this problem.

Hi Markus,
What you're trying to do is discouraged, you shouldn't attempt to access
proxies from within the programmable filter. If you were running paraview in a
client-server setup, it would not work because the filter and its proxy would
exist on different processes.
Anyway, here's some code that may work for you:
import paraview.servermanager as sm
proxies = sm.ProxyManager().GetProxiesInGroup("sources").values()
selfProxy = [p for p in proxies if p.GetClientSideObject() is self][0]
Hope this helps!

Hello,
I do like to program my own plugin based on a Python Programmable filter (PPF).
For some feature (I want to get the file directory of the files from the input
of the very first proxy in the pipeline) I need the proxy object of the PPF.
If I once would have this object I could then loop the Input until there is
none anymore and then read the FileInfo Field. But as described I would need
the proxy object of the PPF first.
I did several tests with the self object as well as with the proxymanager but
could not find a working solution. (I have to say that I am new to ParaView as
well)
Perhaps somebody of this mailing list could help me!?
With kind regards,
Markus
