Hi Pat,<br><br>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)<br><br>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:<br><br><br><span style=" font-family:'Courier'; font-size:8.25pt; color:#800000;">Traceback (most recent call last):</span>

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.<br>
<br>Anyway, here's some code that may work for you:<br><br>
<style>
.ExternalClass p, .ExternalClass li
{white-space:pre-wrap;}
</style>
<p style="margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px">import paraview.servermanager as sm</p>
<p style="margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px"></p>
<p style="margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px">proxies = sm.ProxyManager().GetProxiesInGroup("sources").values()</p>
<p style="margin-bottom:0px;margin-left:0px;margin-right:0px;text-indent:0px">selfProxy = [p for p in proxies if p.GetClientSideObject() is self][0]</p><br><br>Hope this helps!<br>

Hello,<br><br>I do like to program my own plugin based on a Python Programmable filter (PPF).<br>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.<br>
<br>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.<br>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)<br>
<br>Perhaps somebody of this mailing list could help me!?<br><br>With kind regards,<br><font color="#888888">Markus<br> </font></div></div>
