Qtimer singleshot no such slot

In multithreaded applications, you can use QTimer in any thread that has an event loop. To start an event loop from a non-GUI thread, use QThread::exec(). Qt uses the timer's thread affinity to determine which thread will emit the timeout() signal. Because of this, you must start and stop the timer in its thread; it is not possible to start a timer from another thread.

The QTimer class provides repetitive and single-shot timers. As a special case, a QTimer with a timeout of 0 will time out as soon as all the events in the window system's event queue have been processed. This can be used to do heavy work while providing a snappy user interface: processOneThing ... Qt 4.1: QTimer Class Reference - California University of ... The QTimer class provides repetitive and single-shot timers. The QTimer class provides a high-level programming interface for timers.

QT定时器QTimer用法 - 程序园 - voidcn.com You can set a timer to time out only once by calling setSingleShot(true).
