Re: [Vala] [Genie] Chain up TextBuffer

[Jamie McCracken <jamie mccrack gmail com>]

you can use super to access the parent class you are inheriting from
(similar to super in python)

Ergo i belive you need to call super.insert_text (blah) at end of your
overriden call if you want that call to chain up
