To create a nested QAbstractListModel containing a QAbstractListModel

Valerian

I have a structure i.e., Menu containing sub menu
I'm creating the ListModel in Qt subclassing the QAbstractListModel

Here's the code

class MenuItem;

class MenuModel : public QAbstractListModel
{
    Q_OBJECT
public:
    enum MenuRoles {
        NameRole = Qt::UserRole + 1
    };

    MenuModel(QObject *parent = 0);

    void addMenu(const MenuItem &menuitem);

    int rowCount(const QModelIndex & parent = QModelIndex()) const;

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

protected:
    QHash<int, QByteArray> roleNames() const;

private:
    QList<MenuItem> m_menuItems;
};

class MenuItem
{
public:
    explicit MenuItem();
    ~MenuItem();
    void setName(QString name);
private:
    QString             m_strName;
    MenuModel           m_subMenuModel;
};

However I get compile time error saying " error: C2248: 'QAbstractListModel::QAbstractListModel' : cannot access private member declared in class 'QAbstractListModel' "

Is it possible to structure this way? or is there a better way?

Hi,

Where are you getting that error ?

Valerian

at line

QList<MenuItem> m_menuItems;

What private member are you trying to access ?
