QFileSystemModel custom sorting

[Laurent Schall]

I am looking for a way to implement a custom sorting for QFileSystemModel which would not be only alphabetical. f.e. display first folder that are starting with a capital letter in alphabetical order and then display folder that are stating with a lower case letter in alphabetical order.

AAA
AAB
BBB
aaa
abb
bbb

I assume by interposing a QSortFilterProxyModel, e.g. as per start out from https://stackoverflow.com/a/20715646/489865 ?
