Solved Depends on non-NOTIFYable properties

[Milosz]

I have implemented c++ class

class GameList : public QAbstractListModel
{
public:
    GameList(QObject *parent = nullptr);

    int rowCount(const QModelIndex &parent = QModelIndex()) const override;
    QVariant data(const QModelIndex &index, int role = Qt::DisplayRole) const override;

private:
    void fillGameList() noexcept;

private:
    QList<QString> m_gameList;
};

int GameList::rowCount(const QModelIndex &parent) const
{
    if(parent.isValid())
        return 0;

    return m_gameList.size();
}

QVariant GameList::data(const QModelIndex &index, int role) const
{

    if (!index.isValid())
        return QVariant();

    if (index.row() >= m_gameList.size() || index.row() < 0)
        return QVariant();

    if(role == Qt::DisplayRole)
    {
        return m_gameList.at(index.row());
    }
    return QVariant();
}

and QML like that:

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    Row {
        Repeater{
            model: gameList
            Text{ text: data + "  " }
        }
    }
}

I expect that I get data items (there are QString type) but on the form I have [object QObject] [object QObject] ....
and error: QQmlExpression: Expression qrc:/main.qml:13:25 depends on non-NOTIFYable properties:
QQuickText::data

What is wrong with this code?

Thanks in advance

@milosz Hi,

data is a property available from type Item in QML. You need to use display keyword to access "data" from the model.

Text{ text: display }

This is documented here QAbstractItemModel::roleNames()

Alternatively you can provide your own role names by overriding QAbstractItemModel::roleNames()

It works - thanks a lot Gojir4
