[gtkada] Surprised by the changes to GTK 3.0

[Emmanuel Briot]

> I have been using GTK 2.x for a while and going to the 3.0 version really messed up years of personal software development.  I was wondering if anyone has a reference to how one converts from the 2.0 series to the 3.0 series?


Yes, they did make quite a lot of incompatible changes, and the result is somewhat
worth it even though it is painful.
See the GtkAda user's guide which has a partial transition guide that hopefully will
be helpful.
