We are doing that, but still it doesn't run very smoothly. One problem
is that we have to read every 50 ms since that's the frequency how fast
the data can come in. In the meantime, we would like to be able to click
buttons in the GUI (which also receives the data), but that's hardly
possible.

I have to say that all that, in particular the other side of the socket
connection (C++) is mainly written by somebody else, so I don't have a
full understanding. I just started the discussion because I was curious
if we could have timers without widgets.
