The fancy effects are hard work, I think you should look in the gnome
toolbar sources to feel what is needed.

I would rather go the simple route:

AutoHide could just mean to set invisible status for all children
widgets so the container goes automatically to a few pixels of height
(given that the preferred [minimum] size is not set higher).

Move Left/Right is very similar, except the expanding button widget is
not made invisible, and the container just wraps it (some position
correcting may be needed when moving right, and expanding back)

As the documentation states, it can only use positive coordinates,
because visible things can only be drawn/interact, when in the screen
space. If something is to be hidden it should be set invisible no
fancy effects required, that's the norm on GTK/Gnome.

As I'm currently working a lot with Java and even fixing Java VMs
(JamVM/Kaffe) and GNU Classpath code, I think I may partly borrow the
title (Javaman) from my friend Bruno Souza and become the
MonoNJavaMan. Yeah, I may currently be crazier than usual...
