[PySide] using QProcess to run python function

[Frank Rueter | OHUfx]

Hi Florian,
thanks for the reply. This entire thread was posted here, not sure why 
it wouldn't show up for you.

 >>it all really depends on how dummyFunction() looks and how it prints 
to stdout.
It's python code that calls calls other python code which eventually 
calls external image processing programs to do some heavy lifting, which 
print their progress to stdout. E.g.:
dummyFunction() calls fucntionA() which calls fucntionB() which runs the 
external program via Popen.subprocess.

I'm happy to restructure a bit as long as the functions that deal with 
managing the external program stay non-QT so they can be used via 
command line without QT present.

Cheers,
frank
