How to call a function periodically in Qt?

Question

Is it possible to call a function periodically in C++ with Qt function ?
And how to stop the timed function after it is set to be called periodically ?

Answer 1

You can use the QTimer class.

Just declare a QTimer with the desired time interval, wrap your function in a QObject as a slot, and connect the QTimer's timeout() signal to the slot you just declared.

Then, when the condition for stopping calling the function is met, just call QTimer::stop().
