Connect not working with vector of QThreads

[bs55]

I cannot connect my QThread's signal to my main thread slot because of a compilation issue. I guess that it is related to the fact that I use a vector of QThreads...

mainwindow.cpp

void MainWindow::startCapture() {
...
        vector<std::unique_ptr<CaptureThread>> v_ct_Threads(i_SelectedCameras);

        for(int i = 0; i < i_SelectedCameras; i++) {
            v_ct_Threads[i] = std::make_unique<CaptureThread>(i, qsb_Duration->value());
            QObject::connect(&v_ct_Threads[i], &CaptureThread::signalProgress, this, &MainWindow::updateProgress); // Faulty line
            v_ct_Threads[i]->start();
        }
...
}


void MainWindow::updateProgress(int i_Camera, int i_Progress) {
    qpb_Progress[i_Camera]->setValue(i_Progress);
}

capturethread.h

...
/class CaptureThread : public QThread {
    Q_OBJECT
public:
    CaptureThread(int i_Camera, int i_Duration);
    void run();
signals:
    void signalProgress(int i_Camera, int i_Progress);
...
};

error message

.../mainwindow.cpp:156: error: no matching function for call to ‘MainWindow::connect(__gnu_cxx::__alloc_traits<std::allocator<std::unique_ptr<CaptureThread> > >::value_type*, void (CaptureThread::*)(), MainWindow*, void (MainWindow::*)())’
             QObject::connect(&v_ct_Threads[i], &CaptureThread::signalProgress, this, &MainWindow::updateProgress);
                                                                                                                 ^

I use QTcreator 4.4.1 Qt 5.9.2, C++14 on Ubuntu 16.

Change &v_ct_Threads[i] to v_ct_Threads[i].get()
