Starting QTimer In A QThread

Question

I am trying to start a QTimer in a specific thread. However, the timer does not seem to execute and nothing is printing out. Is it something to do with the timer, the slot o

Answer 1

I have created an example that calls the timer within a lambda function:

#include 
#include 
#include 
#include 
#include 
#include 

int main(int argc, char** argv)
{
    QCoreApplication app(argc, argv);

    QThread* thread = new QThread(&app);
    QObject::connect(thread, &QThread::started, [=]()
    {
        qInfo() << "Thread started";
        QTimer* timer1 = new QTimer(thread);
        timer1->setInterval(100);
        QObject::connect(timer1, &QTimer::timeout, [=]()
        {
            qInfo() << "Timer1 " << QThread::currentThreadId();
        });
        timer1->start();
    });
    thread->start();

    QTimer timer2(&app);
    QObject::connect(&timer2, &QTimer::timeout, [=]()
    {
        qInfo() << "Timer2 " << QThread::currentThreadId();
    });
    timer2.setInterval(100);
    timer2.start();

    return app.exec();
}
