hiding a Gnome (bonobo) toolbar?

[Eric Liprandi <eric liprandi gmail com>]

Hi again,

For the same application as mentioned in my previous question (resizing
Gnome::UI::App), would like to "hide" the toolbar.

Once again, the interface was designed with Glade and therefore a
BonoboDockItem was created to contain the toolbar.

What is the proper way of get this BonoboDockItem and then hiding it?
(not just the embedded toolbar).

Thanks in again for the help,

Eric.
