Subclassing widgets?

[Mike Frisch <mfrisch saturn tlug org>]

Can somebody direct me to documentation on subclassing Gtk widgets?  (if
this is even possible...)  I would like to override the List and ListItem
controls to paint the list and list items myself and control the
appearance of the List while retaining the core code. 

Thanks.

Mike.
