Dear John,
thanks for your explanations. I roughly got an idea but I have a few questions:

This is clear.

I assume I can get *it like this:
QList<pqPipelineSource*> sources_and_filters =
pqApplicationCore::instance()->getServerManagerModel()->findItems<pqPipelineSource*>();
But where and when do I have to call that code? Because at the moment my plugin
is executed by clicking on "File / Export" in ParaView, so I don't have any GUI
related code. Everything is on the VTK side.

This sets the name on the proxy.

But what is that doing?

I dont understand how the name actually gets to my exporter. And because a list
of names is more general I would only pass this list to my exporter and not a
single name.
See vtkOpenSGExporter.h / .cxx on Github:

Thank you very much for your help!!
