QML ListView in qml is not updated when model changed - c++

Question

I am trying to update a model in a QML ListView from a cpp file..
Here is my implemenation. I copied evrything to this therfore it will be a little bit bigger from code size.
this is my model implementation albummodel.h
#include <QAbstractListModel>
#include <QStringList>
#include <QQmlListProperty>
class Album
{
public:
Album(const QString &type, const QString &size);
QString type() const;
QString size() const;
private:
QString m_type;
QString m_size;
};
class AlbumModel : public QAbstractListModel
{
Q_OBJECT
Q_PROPERTY(QQmlListProperty<QObject> myModel NOTIFY listChanged)
public:
enum AlbumRoles {
TypeRole = Qt::UserRole + 1,
SizeRole
};
AlbumModel(QObject *parent = 0);
//QQmlListProperty<QObject> getList();
void addAlbum(const Album &album);
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<Album> m_albums;
signals:
void listChanged();
#include <QAbstractListModel>
#include <QStringList>
#include <QQmlListProperty>
class Album
{
public:
Album(const QString &type, const QString &size);
QString type() const;
QString size() const;
private:
QString m_type;
QString m_size;
};
class AlbumModel : public QAbstractListModel
{
Q_OBJECT
Q_PROPERTY(QQmlListProperty<QObject> myModel NOTIFY listChanged)
public:
enum AlbumRoles {
TypeRole = Qt::UserRole + 1,
SizeRole
};
AlbumModel(QObject *parent = 0);
//QQmlListProperty<QObject> getList();
void addAlbum(const Album &album);
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<Album> m_albums;
signals:
void listChanged();
};
This is my albummodel.cpp
#include "albummodel_mediaplayer.h"
Album::Album(const QString &type, const QString &size)
: m_type(type), m_size(size)
{
}
QString Album::type() const
{
return m_type;
}
QString Album::size() const
{
return m_size;
}
AlbumModel::AlbumModel(QObject *parent)
: QAbstractListModel(parent)
{
}
void AlbumModel::addAlbum(const Album &album)
{
beginInsertRows(QModelIndex(), rowCount(), rowCount());
m_albums << album;
endInsertRows();
emit listChanged();
}
int AlbumModel::rowCount(const QModelIndex & parent) const {
Q_UNUSED(parent);
return m_albums.count();
}
QVariant AlbumModel::data(const QModelIndex & index, int role) const {
if (index.row() < 0 || index.row() >= m_albums.count())
return QVariant();
const Album &Album = m_albums[index.row()];
if (role == TypeRole)
return Album.type();
else if (role == SizeRole)
return Album.size();
return QVariant();
}
QHash<int, QByteArray> AlbumModel::roleNames() const {
QHash<int, QByteArray> roles;
roles[TypeRole] = "type";
roles[SizeRole] = "size";
return roles;
}
/*QQmlListProperty<QObject> AlbumModel::getList(){
return QQmlListProperty<QObject>(this, *list);
}*/
and my qml file
import AlbumModel 1.0
ListView {
model: AlbumModel.myModel
delegate: playListThumbnail
Component {
id: playListThumbnail
Item {
Text {
id: albumTitleText
text: type//item_title
}}
....
}
I added the main Programm Code. Hope this is enough for a mvp
Main.cpp
void main() {
qmlRegisterType<AlbumModel>("AlbumModel",1,0,"AlbumModel");
Album g("test", "test");
AlbumModel h();
h.addAlbum(g);
}
But the model isn't updated. Which signal did i miss?
