查询并不意味着是复制的。请改用移动构造

问：

我一直在做一个代码，其中数据库纵，元素被 Qsqlite 数据库和查询保存和编辑，所以我使用的方式是按参数传递查询我不知道它有多糟糕，但每次它通过参数我都会收到这个警告：“ QSqlQuery 已弃用：并不意味着要复制： 改用移动构造“，我想知道正确的方法，我展示了 MainWindow 构造函数（警告在主中指示）。

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{   

    ui->setupUi(this);
    char dirNow[1024];

    db = QSqlDatabase::addDatabase("QSQLITE");
    QString dirfull = QString(_getcwd(dirNow, 1024)) + "\\inventario.db";
    db.setDatabaseName(dirfull);

    if(!db.open()){
        qDebug() << db.lastError().text();
    }

    model = new QSqlQueryModel();

    QSqlQuery query(db);



    if(!query.exec("CREATE TABLE IF NOT EXISTS articulo (codigo INTEGER NOT NULL, nombre VARCHAR(55) NOT NULL, unidades INTEGER NOT NULL, "
                   "categoria VARCHAR(55) NOT NULL, pais VARCHAR(55) NOT NULL, precio DOUBLE NOT NULL, foto VARCHAR(200) NOT NULL, id INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT) ")){
            QMessageBox::information(this, "Error", query.lastError().text());
    }

    if(!query.exec("CREATE TABLE IF NOT EXISTS categorias(valor VARCHAR(55) NOT NULL) ")){
        QMessageBox::information(this, "Error", query.lastError().text());
    }

    //query.prepare("DELETE FROM articulo WHERE  = 1");
    //query.addBindValue("");

    "Warning is here: " id = imprimirArticulos(query);

    "Warning is here: " QObject::connect(ui->registrarBtn, &QPushButton::clicked, this, [=]()->void{registrarArticulo(query); });
    QObject::connect(ui->addImagenBtn, &QPushButton::clicked, this, [=]()->void{subirFoto();});
    "Warning is here: " QObject::connect(ui->buscarBtn, &QPushButton::clicked, this, [=]()->void{filtroArticulos(query);});

    "Warning is here: " imprimirCategorias(query);
    "Warning is here: " QObject::connect(ui->categoriasCBox, &QComboBox::currentIndexChanged, this, [=]()->void{agregarCategorias(query);});

    model->setQuery(std::move(query));
}
