Hello all,

(replying to myself): To add a signal in AlbumSettings class it seems
required to inherit it from QObject, which then complains about
AlbumSettings instance being private (although it was private before, as
well!): (see below)

I read the Signal/Slot tutorial but I'm not sure where to insert an
appropriate signal/slot. My idea is to insert a signal that can be emitted
in AlbumSettings class and a slot that gets connected to the signal in e.g.
DateFolderView() class, which then loads and redraws the icons with the new
settings.

I would appreciate a bit of help :)

Thanks!
