Re: [Discuss-gnuradio] "Catching" end of flowgraph execution with GUI

[Koslowski, Sebastian (CEL)]

I had a similar problem recently. My solution was to subclass the
flowgraph adding the required functionality. Check out the 
_top_block_waiter class in top_block.py. You can reimplement that logic
to e.g. add a time-out the the wait() call on the event or have a
callback executed.
