Is that normal about QListView ?

[Alundra]

Hi,
I have a QListView using icon mode and QFileSystemModel.
That sort correctly by name of files but when I edit one item that doesn't update the sort, the item is at the same place.
I have tried to add a key that call model()->sort( 0 ); but that doesn't sort anything.
How make that sort the item at the end of the edit ?
Thanks for the help
