I have a QTreeView in my program for picking a directory on Windows OS. It works, however, some users complain that in order to pick My Documents they must expand C:\Users\<user name>\Documents, which is quite slow. They'd prefer to access "Libraries" directly on the root level, like in Windows Explorer on the left (Documents, Music, Pictures...). How can I do this with QTreeView and QFileSystemModel? I'm in Qt 5/C++.
EDIT: Windows explorer contains also other items, which I'd like to include: Network and Favourites.
