custom widget with gtk

[Doudieu Siewe Narcisse <nar6doudieu gmail com>]

Hello every world,

I have one suggestion for gnome:

Actually there is a tuto on how to make derived class from gobject but in
the case of gtk nothing is very clear no ideas of which gtk widget to
instantitate, which methods to rewrite etc...another important thing is to
tell to developper about which the parent class and instantiated class and
how to finalize both parent and instantiated class.

Actually I have some problème with gtkbin, gtk doesn't say if this widget
is a windowless widget and when I derived this gtk widget and after packing
into a topleve
l widget, gtkbin can draw its childs on the parent frame but which own a
window. So some people can tell m what is wrong or what I need to implement?
