How to sort an items from custom item role ?

Like QTableView has!

model = new QStandardItemModel(this);
_model->setSortRole(ListView::sortRole);

model = new QStandardItemModel(this);
_model->setSortRole(ListView::sortRole);

To copy to clipboard, switch view to plain text mode 

I know I can do
item->setData(Qt:isplayRole, number); but I add a widget to the item and don't want a display role here
