A simplest ListModel... no example :(

[tomek]

Hi!
I'm trying to make a simplest ListModel accessing QList<Class>.
Could someone take a look and tell me how it should be written?
feed.h:

class Feed
{
public:
    Feed();
    Feed(const Feed &other);
    Feed &operator=(const Feed &other);
 
    QString stringUrl;
    QDate lastFetched;
    QString htmlContent;
};

class Feed
{
public:
    Feed();
    Feed(const Feed &other);
    Feed &operator=(const Feed &other);

    QString stringUrl;
    QDate lastFetched;
    QString htmlContent;
};

To copy to clipboard, switch view to plain text mode 

feedModel.h:

class Feed;
#include <QAbstractListModel>
class FeedModel : public QAbstractListModel
{
public:
	int rowCount ( const QModelIndex & parent = QModelIndex() ) const;
	QVariant data ( const QModelIndex & index, int role = Qt::DisplayRole ) const;
private:
	QList<Feed> list;
 
};

class Feed;
#include <QAbstractListModel>
class FeedModel : public QAbstractListModel
{
public:
	int rowCount ( const QModelIndex & parent = QModelIndex() ) const;
	QVariant data ( const QModelIndex & index, int role = Qt::DisplayRole ) const;
private:
	QList<Feed> list;

};

feedModel.cpp:

#include "feedModel.h"
#include "feed.h"
 
#include <QAbstractListModel>
 
int FeedModel::rowCount ( const QModelIndex & parent ) const 
{
        if (!parent.isValid())
		return (-1);
        else
	    return list.count();
}	
 
QVariant FeedModel::data ( const QModelIndex & index, int role ) const
{
        if (!index.isValid())
            return QVariant();
 
        if (role != Qt::DisplayRole)
            return QVariant();
// This is the hardest place for me!
//        Feed *item = static_cast<Feed*>(index.internalPointer());
        Feed item = static_cast<Feed>(list.at(index.row()));
 
        switch (index.column()) {
            case 0:
                return item.stringUrl;
            default:
                return QVariant();
        }
}

#include "feedModel.h"

#include <QAbstractListModel>

int FeedModel::rowCount ( const QModelIndex & parent ) const 
{
        if (!parent.isValid())
		return (-1);
        else
	    return list.count();
}	

QVariant FeedModel::data ( const QModelIndex & index, int role ) const
{
        if (!index.isValid())
            return QVariant();

        if (role != Qt::DisplayRole)
            return QVariant();
// This is the hardest place for me!
//        Feed *item = static_cast<Feed*>(index.internalPointer());
        Feed item = static_cast<Feed>(list.at(index.row()));

        switch (index.column()) {
            case 0:
                return item.stringUrl;
            default:
                return QVariant();
        }
}
