Actually that seems to be more a flawed API when the slot and the
accessor have the same name.

You did not use the correct syntax.

The compiler told you that the problem was that you did not select one of t=
he=20
overloads. QTcpSocket::error points to multiple functions and you need to=
=20
select one only.

To do that, you need to cast the identifier to a specific signature.

    void (QAbstractSocket:: *sig)(QAbstractSocket::SocketError) =3D
=09&QAbstractSocket::error;
    connect(tcp_socket, sig, this, &MyClass::tcpSocketError);
