There is no default method to get parents so you have to iterate using the parent() method:

QObjectList parents(QObject *qobject){
    if(!qobject)
        return {};
    QObjectList parents;
    const QObject *o = qobject;
    while (QObject *q = o->parent()) {
        parents.push_back(q);
        o = q;
    }
    return parents;
}

QObjectList boxes = parents(ui->checkBox_2);
