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

Hi all (again),

is there any way to catch that my flowgraph has finished execution, to reconfigure it after that and to be able to watch signals in GUI?

In my application I I would like to set some start and end values and to press some kind of start button. After that flowgraph runs for the first set of config parameters and after the execution is finished, it should reconfigure itself and restart it for the second set of parameters, and so on ... Meanwhile I would like to watch some signals in GUI.

I see that top_block_gui class calls infinite main loop and then it blocks there. I suppose that in order to acomplish above stated tast, I would need some kind of callback on flowgraph execution end. Is it possible to make something like this?
