Qt 19:Qt定时器的使用(QTimer) - YouTube
The QTimer class provides repetitive and single-shot timers. The QTimer class provides a high-level programming interface for timers. To use it, create a QTimer, connect its timeout() signal to the appropriate slots, and call start(). From then on it will emit the timeout() signal at constant intervals. QTimer.singleShot in _loadFinished is slow sometimes ... I saw QTimer.singleShot executing the callback (_loadFinishedOK) after 5s and 10s when the 'wait' parameter was 1s. All slots (except the one that fired this timer) were idle. No Such Slot Qobject Connect - clinicaeverest.ro

QTimer.singleShot(200, this, SLOT(updateCaption())); In multithreaded applications, you can use QTimer in any thread that has an event loop.It should be written in such a way that it always returns quickly (typically after processing one data item) so that Qt can deliver events to widgets and stop the...
