[SOLVED] Subclassing QSerialPort - can't connect to slot

[frankiefrank]

I'm trying something that looks straight forward enough:

This is my header:
@
class SerialPort : public QSerialPort
{
public:
SerialPort(QObject *parent = 0);

public slots:
void handleReadyRead();
};
@

And the implementation:
@
SerialPort::SerialPort(QObject *parent)
: QSerialPort(parent)
{
// This connection fails.
bool ok = connect(this, SIGNAL(readyRead()), this, SLOT(handleReadyRead()));
}

void SerialPort::handleReadyRead()
{
}
@

When debugging, I see this warning:
QObject::connect: No such slot QSerialPort::handleReadyRead() in ..\serialport.cpp:6

But I don't understand why this fails. And why the error message refers to a slot in the parent QSerialPort and not to my subclass, SerialPort.

Could anyone spot what I'm doing wrong?

Ah I found the answer through this SO post:
http://stackoverflow.com/questions/4322224/qt-slots-and-inheritance-why-is-my-program-trying-to-connect-to-the-parent-inst

I needed to put the Q_OBJECT macro in my subclass to enable the signals and slots mechanism, even when subclassing a QObject subclass... Works now.
