Detailed Description

QObject::setProperty() sends this event of type QEvent::DynamicPropertyChange to the object when a dynamic property is added, changed or removed. Handle it by reimplementing QObject::event():

bool Widget::event(QEvent *e) {
    if (e->type() == QEvent::DynamicPropertyChange)
        qDebug() << static_cast<QDynamicPropertyChangeEvent *>(e)->propertyName();
    return QObject::event(e);
}

Differences from Qt

None.
