Question

How can I set QFileSystemModel to display just directories?
Or is this impossible at all?

Answer 1

Have never had a chance to use the QFileSystemModel myself, but looking at the docs…did you try setFilter()?

http://doc.qt.io/qt-5/qfilesystemmodel.html#setFilter

http://doc.qt.io/qt-5/qdir.html#Filter-enum

The documentation notes, the default filter is QDir::AllEntries | QDir::NoDotAndDotDot | QDir::AllDirs. That expands to: QDir::Dirs | QDir::Files | QDir::Drives | QDir::NoDotAndDot | QDir::AllDirs, and it says AllDirs is required.

So maybe just:

model->setFilter(QDir::Dirs|QDir::Drives|QDir::NoDotAndDotDot|QDir::AllDirs);
