    1 answer 1

    In QTableView you can set QAbstractItemModel to display (or its successor, QStandardItemModel in your case), respectively, you need to create your own model - the heir of one of these classes, fill it from the .json file, and display it in the table using the void QTableView::setModel(QAbstractItemModel * model). method void QTableView::setModel(QAbstractItemModel * model).

    That is, as required in the lab room, it is usually done in Qt - the logic of filling-saving the model will be in a separate class.
