This is a continuation of the issue I had with the new installation not

I have installed the latest version of GNU Radio from source. When I tried to

I have an application which I can run successfully as a standalone Python
script called from the terminal. When executed, this script is in a while loop.
I would like to execute the script from GNU Radio and interact with it. I have
a toggle button which when pressed calls the script. Once the s

Paul,
Thanks for answering. The following is what I hope is a simplified presentation
of my code that is pertinent to the issue. The top flowgraph is complex. The
FT8_Receive hier block is simple. The connections section below should be
sufficient for explaining it.
I am using a gnu radio flow
Jim,
Thanks for your comments. I think I have been going down the wrong road and
need to refocus on using a callback to resolve my issue.
I have used callbacks all through my project which have been triggered by an
action such as a toggle or a radio button selection. I need to trigger the
call
Thanks for the reply. Looks like that is what I will run with.
