Thanks a lot for this, Nyall. It works a treat!
I did notice a curious behavior, though. The stdout callback seems to only be
called every so often, and there doesn't seem to be a control for that in the
documentation for the relevant objects. Did I miss anything?
Cheers,
Pedro

Hello fellow QGIS'ers.
I have a (new to me) problem in my hands.
I am building an interface to run a large transportation simulation model
(https://polaris.taps.anl.gov/polaris-studio/index.html) from a QGIS plugin,
and I would like to update the interface as the simulation progresses.
The issue here is that this simulation is done inside a compiled C++ executable
from which I cannot emit any QT signals, so I have to do it "manually" by
processing the logfile generated by the application.
I currently don't see a way to do this, as the calling the simulation processes
captures the GIL and I can't update the interface, but is there another way of
doing this?
I am at a bit of a loss, so I appreciate any pointers.
I'd suggest following the approach used by the GDAL processing algorithms. See

Cheers,
Pedro
