The model must be a GtkTreeModel, the GtkTreeModel implementation can be a flat list, implementations are allowed to let rows have children (i.e. it can be a tree of data). I don't know what API python is giving to you, if it's so very different than the C API than that is a good way to obfuscate code and confuse new users. > >>> On the other hand, when I want to read list's selection all I get is >>> the GtkListStore model - list of gobjets and I have to figure out the >>> actual domain object the data comes from. >> >> You don't get a list of gobjects as far as I know, I'm not sure where you >> are >> getting that from. > > [...] > > Ok, I'm noob with Gtk/GLib, so I might've used wrong words.
