No matching member function to call for 'connect' | QEventLoop

Sloppy-1-1

Hi,
I get the following error when trying to use the connect function:

No matching member function for call to 'connect'

The code looks like this:

QEventLoop loop;
connect(OK(), SIGNAL(OK_Pressed()), &loop, SLOT(quit()));
loop.exec();

The signal is generated in the following way:

void Main::OK()
    {
        emit OK_Pressed();
    }

Basically I want to wait for a function to be called and completed (I call on OK() at the end of said function) without a while loop or a similar workaround.

I also have the methods and signals declared:

class Main : public QMainWindow
{
    Q_OBJECT

public:
    Main(QWidget *parent = nullptr);
    ~Main();

signals:
    void OK_Pressed();

private:
    Ui::Main *ui;
    void OK();
}

Hope I've provided enough information, this is my first time posting here.

Hi and welcome to devnet,

Your first parameter is wrong. Connect takes a pointer to a QObject, you pass it the return value of your OK method.
