I'm trying to kill/cancel a QThread. I followed the implementation of <a href="https://mayaposch.wordpress.com/2011/11/01/how-to-really-truly-use-qthreads-the-full-explanation/">https://mayaposch.wordpress.com/2011/11/01/how-to-really-truly-use-qthreads-the-full-explanation/</a>
I create the QThread like this:
and try to stop it on a certain UI event by calling:
My worker looks like this:
Where process calls an API with heavy calculations
My problem is, that after calling quit on the thread, the thread keeps running ie the calculations of the API don't stop. Because the worker only calls the API, I cannot work with a cancel check in the worker loop. Any ideas?
Thanks in advance!
I create the QThread like this:
Code:
workerThread = new QThread();
ImageProcessor* worker = new ImageProcessor();
worker->moveToThread(workerThread);
connect(workerThread, SIGNAL(started()), worker, SLOT(process()));
connect(worker, SIGNAL(finished()), workerThread, SLOT(quit()));
connect(worker, SIGNAL(finished()), worker, SLOT(deleteLater()));
connect(workerThread, SIGNAL(finished()), workerThread, SLOT(deleteLater()));
workerThread->start();and try to stop it on a certain UI event by calling:
Code:
workerThread->quit();My worker looks like this:
Code:
class ImageProcessor : public QObject
{
Q_OBJECT
public:
explicit ImageProcessor(QObject *parent = 0);
~ImageProcessor();
signals:
void finished();
public slots:
void process();
private:
//...
};Where process calls an API with heavy calculations
Code:
void ImageProcessor::process()
{
// API call...
emit finished();
}My problem is, that after calling quit on the thread, the thread keeps running ie the calculations of the API don't stop. Because the worker only calls the API, I cannot work with a cancel check in the worker loop. Any ideas?
