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 Core 5.12.3 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. QTimer Class | Qt 4.8 Detailed Description. 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.. Example for a one second (1000 millisecond) timer (from the Analog ...

You should use the signal/slot mechanism to your advantage - that's what it is there for, and get rid of your interface and class entirely: a single (global/static) function is enough. Consider something like this (QTimer::singleShot itself is a good example of how you should be doing it): QTimer — PySide v1.0.7 documentation - GitHub Pages From then on, the update() slot is called every second.. You can set a timer to time out only once by calling setSingleShot(true). You can also use the static QTimer.singleShot() function to call a slot after a specified interval: QTimer Class | Qt Core 5.12 - sra.co.jp
Qt 4.3: QTimer Class Reference
[QTBUG-69800] QTimer::singleShot() requires a non-const ... The documentation of QTimer::singleShot() states that the context/receiver should be a const pointer to QObject. This is consistent with e.g. QObject::connect(). However, in reality the overloads taking a functor require a non-const pointer, which is both inconvenient and against the documentation and standard practice.
Hi I'd like to do something like this: QTimer::singleShot(5000, this, SLOT(MySlot(iID))); to get the ID (can be 1 to 16) and know which ID did kick off the singleShot. However, that seems not to be possible with on-board tools. Any idea how this can be e...
