Re: custom widget and styles

[Tristan Van Berkom <vantr touchtunes com>]

I'm not so sure how the "syle" api
works but I don't think gtk_style_attach()
makes any duplicates. It's probably just:
GTK_WIDGET(object)->style = style and
maybe a rc_reparse or something like that.

I can tell you that if you want your style to
be on a class scope (all instances use the
same object) point to it in your class structure;
create it in _class_init; destroy it in _class_finalize;
but you probably want one "style" per instance so
create it in _init (instance_init) and in _class_init
override G_OBJECT_CLASS(obj)->finalize and destroy it
in your version of finalize.

this is the wierd thing; the tools you have in a GTypeInfo
are

instance_init
class_init
class_finalize
(base...*)

and G_OBJECT_CLASS(obj)->finalize is
actualy a method of the GObjectClass.
