Why is calling QSqlTablemodel::setData from const function is allowed?

I am calling QSqlTablemodel::setData from inside a const function and the compiler is not giving me an error. This doesn't seem right. Anybody know why this is allowed?

Example:

Code:

---

class myClass : public QObject
{
  public:
    myClass(QSqlDatabase *db);
    ~myClass();
  private:
    setRecord(int row, const QSqlRecord & record) const;
    mySqlTableModel *myModel;
    QSqlDatabase *dataBase;
}
 
class mySqlTableModel : public QSqlTableModel
{
   Q_OBJECT
   public:
     explicit mySqlTableModel(QWidget *parent = Q_NULLPTR, QSqlDatabase db = QSqlDatabase());
     ~mySqlTableModel();
     // various public and private members but no override of setRecord
}
 
myClass::myClass(QSqlDatabase *db) : QObject()
{
   database = db;
   myModel = new mySqlTableModel(Q_NULLPTR, *db);
}
myClass::~myClass()
{
   delete myModel;
}
bool myClass::setRecord(int row, const QSqlRecord & record) const
{
    for (int column = 0; column < recprd.count(); column++)
    {
       if (!myModel->setData(myModel->index(row, column), record.value(column)))  // no compile error for calling setData?
       {
           return false;
        }
    }
    return true;
}

Thanks!
