Unable to abort the worker thread using singleshot timer

I have a Worker class with doWork() function/slot where in I do stuff using while loop coupled with QThread. I'm trying to break out of loop using a singleshot timer but doesn't seem to be working though.
Could someone guide me what's wrong in my code. Thanks.

Code:

---

#include <QCoreApplication>
#include <QThread>
#include <QTime>
#include <QTimer>
#include <QDebug>
 
class Worker : public QObject
{
	Q_OBJECT
	int m_continue;
public:
	Worker() : m_continue(1)
	{
		qDebug() << "Worker::Ctor";
		QTimer::singleShot(7000, this, SLOT(discontinue()));  // Expecting to call discontinue() after 7 secs.
	}
	~Worker() { qDebug() << "Worker::Dtor"; }
private slots:
	void doWork()
	{
		while(m_continue)
		{
			qDebug() << QTime::currentTime().toString("HH:mm");
			QThread::sleep(2);
		}
		emit done();
		qDebug() << "Done!";
	}
	void discontinue()
	{
		qDebug() << "Aborting ...";
		m_continue = 0;
	}
signals:
	void done();
};
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
	QThread thread;
	Worker worker;
	worker.moveToThread(&thread);
	QCoreApplication::connect(&thread, SIGNAL(started()), &worker, SLOT(doWork()));
	QCoreApplication::connect(&worker, SIGNAL(done()), &thread, SLOT(quit()));
	QCoreApplication::connect(&worker, SIGNAL(done()), &worker, SLOT(deleteLater()));
	QCoreApplication::connect(&thread, SIGNAL(finished()), &thread, SLOT(deleteLater()));
	thread.start();
 
	return a.exec();
}
 
#include "main.moc"

Try to change dWork to this.

Code:

---

void doWork()
{
    if(m_continue)
    {
        qDebug() << QTime::currentTime().toString("HH:mm");
        QTimer::singleShotQThread(2000, this, SLOT(doWork()));
    }
    else
    {
        emit done();
        qDebug() << "Done!";
    }
}

While loop is blocking event loop in thread.

Thank you.

Given the scenario with QThreads implementation using Worker object, what would be the correct way to implement a QThread to run continuously and with a option to abort it when required.
What I looking for is, if the above method just enough or is there a better way to do it?
Thanks!

It is simple & sufficient.

You have to remember : if You want to communicate with Worker via signals and slots You can not block thread event loop.
