QTableView connected with QSqlTableModel flickers (scrolls to the bottom and returns)

[ironexmaiden]

I changed my code and I remove the sql query exec I tried to modify the data with the setData but unfortunately nothing happened

bool AttributesModel::setData(const QModelIndex &index, const QVariant &value, int role)
{
    if(index.column() == STATUS_INDEX) {
        bool ret = QSqlTableModel::setData(index, value == Qt::Checked ? Qt::Unchecked : Qt::Checked, role);
        database().commit();
        this->submitAll();
        return ret;
    }
    return QSqlTableModel::setData(index, value, role);
}

bool AttributesModel::setData(const QModelIndex &index, const QVariant &value, int role)
{
    if(index.column() == STATUS_INDEX) {
        bool ret = QSqlTableModel::setData(index, value == Qt::Checked ? Qt::Unchecked : Qt::Checked, role);
        database().commit();
        this->submitAll();
        return ret;
    }
    return QSqlTableModel::setData(index, value, role);
}
