how to pass a model to playlist qml type?

[newbiSoso]

I'm trying to implement a music player using Playlist type but didn't know how to pass my model to it, it's a c++ model that contains the URL's of my music:

static QStringList pathList;

….
int main(int argc, char *argv[]){
…..
QDirIterator it("E:/", QStringList() << "*.mp3", QDir::Files, QDirIterator::Subdirectories);
        while (it.hasNext()){
            qDebug() << it.next();
            pathList.append(it.next());
        }
    QQmlContext *ctxt1 = engine.rootContext();
    ctxt1->setContextProperty("pathModel", QVariant::fromValue(pathList)); //used model pathmodel

….
}

and my playlist code on the qml side:

Rectangle{
                width: page.width
                height: page.height
                Audio {
                       id: player;
                       playlist: Playlist {
                           id: playlist
                           PlaylistItem { source: "song1.ogg"; } //I want this process to be automated instead of doing it manually
                           PlaylistItem { source: "song2.ogg"; }
                           PlaylistItem { source: "song3.ogg"; }
                       }
                   }
                   ListView {
                       model: playlist;
                       delegate: Text {
                           font.pixelSize: 16;
                           text: source;
                       }
                   }
                   MouseArea {
                       anchors.fill: parent;
                       onPressed: {
                           if (player.playbackState != Audio.PlayingState) {
                               player.play();
                           } else {
                               player.pause();
                           }
                       }
                   }
            }

I tried using App list view type but I only managed to play/pause a song on click and couldn't implement functions like autoplay next when a song finishes or stop the current one when another song is selected.
