I want to base it off the 2.8 release later this summer I'll post to the list once I have it "together". I have no plans to maintian perfect compatibility with the desktop version but want to keep the changes resonable i.e. no uneeded floating point reduced widget set etc. One of the biggest changes I have in mind is rewriting GObject to use libffi and simplifying the constructor chain. Anyone who is intrested in embedded GTK or doing a serious rewrite of GObject using libffi and simplification of the constructors please email me. If there is enough intrest we could start the project now. Mike _______________________________________________ gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
