Hello all,
I have a QTimer in my application that runs every 40ms. It doesn't run
continuously, but I recall the start function every time my timer function
is done so that the timer doesn't drift over time. My question though is
about timeout overrun. If the system is busy, and so the timer is late,
will Qt::PreciseTimer be more likely to return on time than
Qt::CoarseTimer? In other words, I'm ok with the 5% accuracy of
Qt::CoarseTimer normally (when the system isn't busy), but when the 40ms
timer is getting close to 60ms, I want to avoid timer overrun.
Does anyone have any more precise info about Qt::PreciseTimer than the
docs which say:
"All timer types may time out later than expected if the system is busy
or unable to provide the requested accuracy. In such a case of timeout
overrun, Qt will emit activated() only once, even if multiple timeouts
have expired, and then will resume the original interval."
Thanks!
Josh
