Jim,
This really has little to do with GNU Radio and more to do with Python/GUI
concurrency.
As a general rule, a GUI should never perform a “blocking” operation. Since
your application has its own “event loop”, it is fatal to pass control to it
from another event loop.
Rather than calling
on GNU Radio application could achieve them. Maybe
my brain is frozen in the past and it is very doable now, but that hasn’t been
my experience.
