You can check the thread affinity of an object and the current thread that will display the problem you encounter. Use a queued signal into the QTimer thread to sent the start (it will be delayed until the thread process the event, hopefully you do no need precision there).

I'm trying to have a simple singleton class, but it doesn't appear that I can use timers? HardwareInterface::HardwareInterface(QObject *parent) : QObject(parent) { m_timer = new QTimer(this); connect(m_timer, &QTimer::timeout, this, [=](){ qDebug() << Q_FUNC_INFO; }); m_timer->start(100); // QObject::startTimer: Timers can only be used with threads started with QThread } main.cpp: int main() { ... qmlRegisterSingletonInstance("com.company.example", 1, 0, "HardwareInterface", &hardwareInterface); ... How do we go about using timers in singletons? _______________________________________________ Interest mailing list Interest@qt-project.org https://lists.qt-project.org/listinfo/interest
