Best Practice - delete pointer QAbstractButton in QMessageBox

Good day,
In this example below, delete the pointer is correct for the QAbstractButton or not I do that? What is the best practice?

Code:

---

QMessageBox msg(QMessageBox::Warning, tr("APP"),
					QMessageBox::tr("blablablablablabla"), 0, this);
 
	QAbstractButton *sim = msg.addButton(tr("&Sim"), QMessageBox::AcceptRole);
	QAbstractButton *nao = msg.addButton(tr("&Não"), QMessageBox::RejectRole);
	msg.exec();
 
	delete sim;
	delete nao;
 
	if (msg.clickedButton() == sim)
	{
              ......
        }

Those buttons are children of the messagebox and they'll get automatically destructed when the message box itself gets destructed. You don't have to delete them yourself at all. For more details, see: Object Trees and Object Ownership.
