Hi David! Sorry about the delay I was abroad and without any way to
connect to the internet.
Thank you very much. I've tried to put the principal inside the
timerEvent. It work but it lags. In fact I've set the interval of the
Timer to 2 seconds because the principal loop takes roughly 2seconds
but it's not very accurate...
Is there a way to do the principal loop, show it on the screen, then
redo the loop?
Thanks again!
Fabien
