HanDict - Hanzi Learner’s Dictionary
Currently in alpha version, and un-released, HanDict will hopefully become a full-featured Hanzi dictionary program. In the meantime in can serve as a good Gtk2Hs demonstration. It is written by Jean-Philippe Bernardy.
- plenty of Unicode, for displayng the Hanzi characters.
- plenty of TreeViews, both true trees and plain lists, and user-sortablility as well.
