Accessing data from a model when an item is clicked in a view

[vfernandez]

You can add a method to MovieListModel that provides the QHash for the item:

QHash<QString, QString> MovieListModel::movieData(const QModelIndex& index)
{
    if(index.row() < 0 || index.row() >= list.count()) {
        return QHash<QString, QString>();
    } else {
        return list.at(index.row());
    }
}

QHash<QString, QString> MovieListModel::movieData(const QModelIndex& index)
{
    if(index.row() < 0 || index.row() >= list.count()) {
        return QHash<QString, QString>();
    } else {
        return list.at(index.row());
    }
}

Then in loadMovieItems you can do this:

MovieItemArea::loadMovieItems(const QModelIndex& movieData)
{
    QHash<QString, QString> movieData = model->movieData(movieData);
    QMessageBox::information(this, tr("List name"), movieData.value("name"));
}

MovieItemArea::loadMovieItems(const QModelIndex& movieData)
{
    QHash<QString, QString> movieData = model->movieData(movieData);
    QMessageBox::information(this, tr("List name"), movieData.value("name"));
}
