Hasnt been swigged. This would be neat because the errors could pop up
in a little message window in the GUI.

No. Its more of a global process thing, rather than a per instance.
This is basically a swig directors use case, and there isnt any public
header c++ header stuff to expose. You are basically looking at a custom
handler in the .i file,
and a little routine in the init.py
I'm not in a state of implementing it right now, but if you want some
inspiration, the python blocks code uses the existing gnuradio swig
director stuff, you should take a look:

Re: [Discuss-gnuradio] catching UHD errors in Python
Will try "try" "catch"... this very well may have been a dumb question. I blame
it on lack of sleep.

Subject: [Discuss-gnuradio] catching UHD errors in Python
Is there a good way to catch UHD errors in Python? I will look into
gr_async_msg_source for handling L's, O's, U's, and S's, but how does one catch
UHD runtime errors such as if the Ethernet cable gets disconnected from an
N200? UHD docs describe registering a handler method but has this functionality
been swigged into GNU radio?
Would it make sense to define a handler function in gr_uhd_usrp_{sink|source}?

[Discuss-gnuradio] catching UHD errors in Python
Is there a good way to catch UHD errors in Python? I will look into
gr_async_msg_source for handling L's, O's, U's, and S's, but how does one catch
UHD runtime errors such as if the Ethernet cable gets disconnected from an
N200? UHD docs describe registering a handler method but has this functionality
been swigged into GNU radio?
Would it make sense to define a handler function in gr_uhd_usrp_{sink|source}?
