[Qt-interest] QDirModel v. QFileSystemModel ?

[Alexis Menard]

Yes, please use the QFileSystemModel, better tests coverage, better  
performance, better everything :D.

QDirModel is not deprecated but it doesn't receive that much love  
because we have QFileSystemModel.

setRootPath move the QFileSystemModel to the root you want to. But of  
course you have to limit the view by using
setRootIndex like you did, otherwise it will display from / (if linux)  
all the time. It's because what ever the rootPath will
be in QFileSystemModel, it always create the hierarchy from the root  
of the system. setRoothPath(/home/user/plop) will
create internally a root /, a child "home" of /, a child "user" of  
home, and a child "plop" of user. That's why QTreeView will always
display from the top unless you call setRootIndex.

Hope it helps.
