One listview, multiple XmlListModels

  • Hi,

    i searched the forum but didn't find anything that fits to my problem. Is it possible to have more than one XmlListModel attached to a listview?

    Do i have to make something with c++ or is it possible with qml?

    Thank you.

  • A list can only have 1 model, what will it do if your 2 models do not have the same number of rows ?
    You can either use C++ to merge your 2 XML into one model and expose it to QML or bind one XmlListModel to the list and access the other manually using XmlListModel.get(index)

  • Hi,

    thank you for your answer. both models are having a "link" tag, so i thought i could bind them and query it.

    Anyway i am already making a custom model (merging them) and make it available to qml.

  • Ok i have an other related question.

    I have so far:

    • A new Model which extends QAbstractListModel.
    • QNetworkAccessManager requests (get) in the constructor.
    • A "replyFinished" slot, where i parse the requests with QXmlStreamReader
    • Add the Data to the Model (QList<News>) (in the replyfinished).
    • News is just simple a class for link,pubdate,description and headline

    this is my model
    class NewsModel : public QAbstractListModel
    enum NewsRoles
    LinkRole = Qt::UserRole + 1,

        NewsModel(QObject *parent = 0);
        void addNews(const News &news);
        int rowCount(const QModelIndex & parent = QModelIndex()) const;
        QVariant data(const QModelIndex & index, int role = Qt::DisplayRole) const;
    public slots:
        void replyFinished(QNetworkReply* reply);
        QList<News> m_news;


    if i add news on startup than they are shown in the listview, but not the one i put in the model manually (edit: not manually, through the QNetworkAccessManager in the replyfinished method).
    NewsModel newsModel;
    view.rootContext()->setContextProperty("newsmodel", &newsModel);

    Do i have to fire a event? Or am i missing a method?


    I just had to look into the addNews method, which was working, so you don't need to fire a event:
    beginInsertRows(QModelIndex(), rowCount(), rowCount());
