Qt: printscreen key in keyPressEvent

Question

When I press the keys, this code works, but not with the Print Screen button.

void KeyHooker::keyPressEvent(QKeyEvent *event)
{
    qDebug() << event->key();
}

Q. How can I capture the print screen key?

The problem is the OS grabs this before it reaches your code: http://qt-project.org/forums/viewthread/18610/#90901

For this you need to use Microsoft LowLevelKeyboardProc
