Did you look in the InitServerManager function? you can see how we manually
start up a server manager. We tell it that we are a PVBATCH (ie no connection
required from a client). All you need to do is poke around with this code and
set the application type to a CLIENT, then instantiate a connection.
Once you've done that, the proxy related stuff is all business as usual.

try ... almost everywhere in DemoCPPipeline. Proxies are used for everything.
You must need glasses if you didn't see any of it!
(and yes SMAdapator is just there for me to copy and paste stuff from. Most of
the convenience functions in the paraview source code are in pqSMadaptor, but
make use of Qt classes which I'm not interested in).

Subject: AW: [Paraview] low level C++ example how to communicate with pvserver
Dear John,
thank you very much for sharing the example. However, I don't see how I can
make
use of it in relation to my original question. I am not sure whether the reason
is that I am not enough familiar with the Paraview concepts or because the
actual server manager usage examples that I am looking for are left out in your
code.

What do you mean by "I manually instantiate the pvserver manager stuff"? Please
mention, where this takes place in your code. Can you roughly describe how
"instantiating the pvserver manager stuff" can be replaced by connecting to a
running pvserver? Because this was my actual problem.
The only relation to server manager classes (vtkSMProxies) I find in your code
is in the files SMAdaptor.h and SMAdaptor.cxx, but these are included or linked
nowhere else.
I am sure your example may give some answers to my initial question, but due to
my limited knowledge I only see a MPI VTK application without obvious
connection
to pvserver communication. Would you help with further explanations?
Regards,
Thomas
