QTimer start specific time

Question

I try to start timer at specific time like 02:30. Every day it starts at 02.30.

Is it possible? Do you have any idea?

Thank a lot.

Answer 1

QTimer doesn't handle specific times of day natively, but you could use it in conjunction with QDateTime to get what you want. That is, use QDateTime objects to figure out how many seconds are between (right now) and 2:30 (QDateTime::msecsTo() looks particularly appropriate here), then set your QTimer to go off after that many seconds. Repeat as necessary.

Answer 2

Depending on the required resolution, you could use an ordinary QTimer that fires let's say every minute.
In the timerEvent, you could check if you are on the right time (using QDateTime), and trigger the necessary event.
