QThread:create syntax

Sailor Rick

I am trying the new QThread::create introduced in 5.10 for the first time, but I think I have syntax issues. I want to run a threaded function called "process" in my worker class and pass two arguments with it but it can not link to the public slot in the worker thread as it is not yet defined; I am using Creator 4.7.2 and QT 5.11.2

QThread *thread = QThread::create(process(data,list));  // has no reference to validate that "process" exists
    parameters_workerThread* worker = new parameters_workerThread();
    worker->moveToThread(thread);

So I re-arranged my code and added the reference to the worker class but gave me an invalid use of void.

parameters_workerThread* worker = new parameters_workerThread();  // invalid use of void
    QThread *thread = QThread::create(worker->process(data,list));
    worker->moveToThread(thread);

My worker header file looks like this:

class parameters_workerThread : public QObject
{
    Q_OBJECT
public:
    
    parameters_workerThread();
    ~parameters_workerThread();

public slots:
    void process(QByteArray list, QStringList data);

I am compiling with: MingW32- gcc version 5.1.0 (tdm64-1)
Any direction would be most appreciated

The answer is std::bind

parameters_workerThread* worker = new parameters_workerThread();
QThread *thread = QThread::create(std::bind(&parameters_workerThread::process,worker,data,list));
worker->moveToThread(thread);
thread->setParent(this);
thread->start();
