Can we connect QTimer::SingleShot with a slot taking ... Hi all, I have a short question: Is it possible for this kind of connection to work: (Assume that all we need is defined) QTimer::singleShot(1000,this,SLOT(vSlot(2,3))); I know that it is possible to connect a QTimer::singleShot(...) with a slot not taking any args, but Can we do the same with a slot taking arg? QTimer Class | Qt 4.8 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. Qt 4.8: QTimer Class Reference - University of Texas at Austin 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.

Qt - QTimer::singleShot equivalent for QML
Класс QTimer содержит статический метод singleshot() для одноразового режима отработки таймера ( singleshot). С его помощью можно запустить одноразовый таймер без создания объекта класса QTimer. Первый параметр метода задает интервал запуска, а второй... Не срабатывает QTimer singleShot Не срабатывает слот, передаваемый в QTimer::singleShot, если: 1. Вызвать QTimer::singleShot, передать слот и задать интервал 2. Свернуть приложение 3. Подождать интервал Если успеть развернуть до того, как интервал закончится, то слот выполнится. В то время как анимации...
