GNOME Bugzilla – Bug 62175
Simple tree widget
Last modified: 2015-02-16 14:01:26 UTC
It might be nice to have a super-simple wrapper around GtkTreeView that hides all the auxiliary objects and so on, but isn't very flexible at all.
gtkmm has achieved this, so it would be worth looking at the gtkmm TreeView API for inspiration: http://www.gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/ch08s02.html#id2515252
Nobody has worked on this in 14 years. Time to retire this request.
