Yes, that's lazy man approach, using timer instead of parallel thread.
The advantage is that you avoid race-conditions (though I think you miss stop()
inside closeEvent()?).
The drawback is that's it's difficult to understand the interaction between
the two timers now. I stared on the code for couple minutes and it was
not clear to me what is the idea behind your stop/start changes.

JMarc's warning about ineeficiency of counting remain unaddressed, though
it migh not be visible because of 300ms update sampling frequency.
