QTimer from a non QThread

[A Former User]

Can QTimer be called from a normal C++ main and not a QThread or a main using a QCoreApplication?

Can QTimer be called from

What does this mean?
A timer object will generate the timeout() signal at (almost) regular intervals, you can subscribe to that and do whatever you want. What do you want to call from a QTimer instance? If you mean to use QTimer without an event loop (i.e. without QCoreApplication), well then, no you can't do that.

No. If you want to use QTimer, then you need QCoreApplication::exec() or QThread::exec().
