Running a member function in a QtConcurrent thread

[dwilliams]

I have a member function that runs to call a device SDK. It works, but I need to run it in a thread.

//Working method:
void DtXrayDetector::startDeviceAcquisition(QString debugID) {
    writeDebugLogEntryWithMutex("DtxRayDetector::startDeviceAcquistions for " + debugID);

    _dt.xAcq->Snap();
}

//Desired method:
void DtXrayDetector::startDeviceAcquisition(QString debugID) {
    writeDebugLogEntryWithMutex("DtxRayDetector::startDeviceAcquistions for " + debugID);
    QFuture<void> qf;
    qf = QtConcurrent::run(_dt.xAcq->Snap());

}

I get an error: No matching function for call to run.

I'm guessing this is a syntax issue that I just don't understand. I've tried a couple of variations that haven't worked. Do you see what I need to do differently?

@dwilliams said in Running a member function in a QtConcurrent thread:

Is _dt.xAcq as QObject sub-class instance and Snap() a slot?
In this case, supposing xAcq class name ist XAcq you can do:

qf = QtConcurrent::run(_dt.xAcq, &XAcq::Snap);

That worked. Thank you!
