How to sort a QComboBox in Qt4

[jpn]

combo->addItems(QStringList() << "B" << "C" << "A"); // "B","C","A"
// for sorting you need the following 4 lines
QSortFilterProxyModel* proxy = new QSortFilterProxyModel(combo);  // <--
proxy->setSourceModel(combo->model());                            // <--
// combo's current model must be reparented,
// otherwise QComboBox::setModel() will delete it
combo->model()->setParent(proxy);                                 // <--
combo->setModel(proxy);                                           // <--
// sort
combo->model()->sort(0); // "A","B","C"

combo->addItems(QStringList() << "B" << "C" << "A"); // "B","C","A"
// for sorting you need the following 4 lines
QSortFilterProxyModel* proxy = new QSortFilterProxyModel(combo);  // <--
