Qthread n QTimer Problem

[jacek]

thanks jacek! i am trying this code. My purpose is while reading from fifo gui shouldn't be blocked and it keep o updating as well. [...] Will not this code will block event loop.

It won't block the event loop, because it will happen in a different thread.

That ws the reason i was reading elements from fifo one at a time.

In that case maybe you don't need that timer at all? Maybe a QThread::sleep() will be enough? How often that device will produce data?

an algo will write points to fifo. Appx every second

If the thread only reads data, maybe it's enough to do a blocking (temporary) read in the other thread without any need for other sync mechanisms. "waitForReadyRead" may be helpfull here.
