54 * @short A sort & filter model for hierarchical item models.
57 * - When sorting, numbers are treated as a whole instead of on a
58 * character-per-character basis. For example, @c myFile-10 is sorted after @c myFile-9.
59 * - When filtering, it behaves as usually is expected when the item model is hierarchical. That is,
60 * an item is shown if it matches or any of its children matches.
