How to stop QThread?

**vespasianvs** · 14th March 2010, 01:42

Hi, this problem might sound weird, but it got me crazy

as I just started using QThread. Here is a short program to test using QThread.

Qt Code:

Switch view

#include <QThread>
#include <QCoreApplication>
#include <QDebug>
 
int main (int argc, char** argv) {
	QCoreApplication app(argc, argv);
	QThread t;
	t.start();
	if (t.isRunning())
		qDebug() << "thread is started";
	//t.exit();
	//t.quit();
	t.terminate();
	qDebug() << "try to stop thread";
	if(!t.isRunning())
		qDebug() << "thread is stopped";
	return app.exec();
}

#include <QThread>
#include <QCoreApplication>
#include <QDebug>

int main (int argc, char** argv) {
	QCoreApplication app(argc, argv);
	QThread t;
	t.start();
	if (t.isRunning())
		qDebug() << "thread is started";
	//t.exit();
	//t.quit();
	t.terminate();
	qDebug() << "try to stop thread";
	if(!t.isRunning())
		qDebug() << "thread is stopped";
	return app.exec();
}

To copy to clipboard, switch view to plain text mode

I tried exit(), quit() and terminate() and waited for a long time.
The expected "thread is stopped" never ever shows up (no matter how long I waited). The thread is like running forever. Could anyone help me with this and show me how to properly stop a QThread?

Thank you.
