Integrate a textual GUI with a blocking poll like API.

[chaudron]

Hi,

I would like to integrate a TUI using textual to some of the BCC scripts I've written. However, BCC uses a blocking poll approach with a callback.

So a short snippet:

def callback():
}
   # Update some TUI widget instead of doing a print() with some data
}
...
...
    while 1:
        try:
            b.ring_buffer_poll()    # This will call a previously assigned callback when something is in the buffer.           
        except KeyboardInterrupt:
            break
...

I was wondering if someone can give some pointers on how I could simply integrate this with a textual App like approach.

Thanks,

Eelco
