How to get color of pixel or point?

[qt_developer]

I have used this code and seems that works fine:

QPixmap qPix = QPixmap::grabWidget(ui->myWidget);
    QImage image(qPix.toImage());
    QColor color(image.pixel(0, 1));

QPixmap qPix = QPixmap::grabWidget(ui->myWidget);
    QImage image(qPix.toImage());
    QColor color(image.pixel(0, 1));

To copy to clipboard, switch view to plain text mode 

Thanks!
