Developing applications using the beta GObject library (fwd)

["Fabricio Barros Cabral \"FX\"" <fbc mailbr com br>]

Hi all!

I'm trying develop an application using the beta GObject library, but I'm
very confused. I'm not understand the concepts about interfaces
(GTypeInterfaces). My object class don't need signal's, I must use
InterfaceClass, ObjectClass or both?

Somebody could me send a small example (the classical Point, Circle,
Shape is very good!) using de GObject library?


Thanks for this advance, and sorry for my bad english! :)
