get a ptr of raw data from screen shot

I get a screen shot with this code:

Code:

---

QPixmap originalPixmap = QPixmap::grabWidget(this);
    QImage *image = new QImage(originalPixmap.toImage());
    image->save("/home/saman/Desktop/image.png");

---

Now, I want to send raw data grabbed from grabWidget over the socket. On the other end, machine receives this raw data and creates a gl texture of it.

As you see, the return value of grabWidget is a QPixmap, I also checked the method data_ptr(), which I think returns what I want with DataPtr format. this format is not recognizable by the compiler though! any idea how to resolve this?

You are looking for QImage::bits()

Cheers,
