maximizing dock items...

[Chris Phelps <chicane reninet com>]

Does anyone know how one would have a dock item expand as wide as the
app that it is in? I know that there must be a way, because my menu's
and my toolbar both go all the way across, just not the dock item that I
added with gnome_app_add_docked(yadda, yadda);

Thanks for any help,
