QThread: Rarely. Very little in the average application requires threads in Qt.
QTimer: Quite often. Useful for repeating tasks or delayed execution of single tasks.

The two are not related.

Thankyou
But in my application i have to read data from piece of hardware and plotting this into qwtplot widget,so if i choose QTimer for updating plot it is very slow compared to QThread.

It's not about choosing the right technique that matters, it is about proper usage of the one you choose.
