QDirModel - show directory ".."?

[jamd]

Using QTreeView and QDirModel can access local
file system but the directory ".." does not appear.

How to show directory ".."?

Appears on the following way:

(none)
|-AA
|-BB

|-AA
|-BB

Using QTreeView and QDirModel can access local

It is because ".." is really not part of the directory tree, it is only needed if you have a flat, table-like, view.

How to show directory ".."?
Two ways:
1. Subclass QDirModel and reimplement for example data(), rowCount() and maybe some others
2. Subclass QAbstractProxyModel and implement a proxy between the dir model and the view which will add the item on the view's side.
