One listview, multiple XmlListModels

qtdeveloper1

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
{
Q_OBJECT
public:
enum NewsRoles
{
LinkRole = Qt::UserRole + 1,
DescriptionRole,
DateRole,
HeadLineRole
};

    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);
private:
    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;
newsModel.addNews(News("www.test.com","test","test","test"));
view.rootContext()->setContextProperty("newsmodel", &newsModel);
@

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

EDIT:

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());
m_news.append(News("1","2","3","4"));
endInsertRows();
