Description

If you press a modifier key and scroll with a mouse wheel the modifier key is not recognized.
It's working with a touchpad like the "Magic Trackpad".
It doesn't matter if one or more input devices are connected
It was working in Qt 4

To check this behavior you can overwrite the wheelEvent function of a QWidget like this:

void wheelEvent(QWheelEvent *event) {
    if (QApplication::keyboardModifiers() & Qt::ShiftModifier) {
        printf("shift + ");
    }
    if (event->modifiers() & Qt::ControlModifier) {
        printf("ctrl + ");
    }
    if (event->modifiers() & Qt::AltModifier) {
        printf("alt + ");
    }
    if (event->modifiers() & Qt::MetaModifier) {
        printf("meta + ");
    }
    if (event->modifiers() & Qt::NoModifier) {
        printf("no modifier + ");
    }
    static int tmp = 0;
    printf("scrolling %d\n", tmp);
    tmp++;
}
