Answer 1

Если ваша постоянно работающая функция не замораживает интерфейс, т.е. выполняемые в ней действия не занимают много времени, то вам достаточно QTimer, которые предоставляет повторяющиеся и однократные таймеры.

Иначе вам ее надо поместить в дополнительно созданный поток и оттуда посредством сигналов и слотов взаимодействовать с основным интерфейсом.
