QTreeView: get current sort column and order

How can I get the current sort culumn and the order? I need this because I want to save the order to a file so I can automatically load the order on restart.

Is it possible to get the culumn width too?

use this method to determinate sort column

Code:

---

int QHeaderView::sortIndicatorSection () const

---

and use this method to determinate sort order

Code:

---

Qt::SortOrder QHeaderView::sortIndicatorOrder () const
