How do I get the items selected from a QListView? - c++

Question

{
...
nrow = 10;
ncol = 1;
/*create QListView */
m_listView = new QListView(this);
m_listView->setGeometry(QRect(QPoint(0,100), QSize(100, 150)));
QStandardItemModel *model = new QStandardItemModel( nrow, 1, this );
//fill model value
for( int r=0; r<nrow; r++ )
{
QString sstr = "[ " + QString::number(r) + " ]";
QStandardItem *item = new QStandardItem(QString("Idx ") + sstr);
model->setItem(r, 0, item);
}
//set model
m_listView->setModel(model);
m_listView->setSelectionMode( QAbstractItemView::ExtendedSelection );
connect(m_listView, SIGNAL(pressed(QModelIndex)), this, SLOT(hItem(QModelIndex)));
}
void MainWindow::hItem(QModelIndex m)
{
QItemSelectionModel *selectionModel = m_listView->selectionModel();
m_txt2->setText(QString::number(selectionModel->selectedIndexes().at(0),'d',0));//???
//not sure how to get the items selected: index and string per selection
}

I just tested this for my own needs and it works in Qt 5.1.
I'm pretty new to C++ so in this line:
foreach(const QModelIndex &index, list){
I don't know if the const and the dereferencing (&) is needed - it works with or without. I cobbled this together from various examples I've seen.
Perhaps someone who understands C++ better can comment.
void MainWindow::on_keywordsList_clicked(const QModelIndex &index)
{
QModelIndexList list =keywordListView->selectionModel()->selectedIndexes();
QStringList slist;
foreach(const QModelIndex &index, list){
slist.append( index.data(Qt::DisplayRole ).toString());
}
qDebug() << slist.join(",");
}
