the work on the object arguments is continued in the 1.1 branch of gtk.
there are a bunch of widgets supporting them now, and i'm constantly working
on increasing the amount of widgets that feature the object arguments.
containers now implement child arguments as well. this works similar to widget
arguments, but the values are associated with a certain container<->child
relation.
e.g. if you got a hbox containing a button, you can do this:

gtk_widget_set (GTK_WIDGET (hbox),
                "homogeneous", TRUE,
                NULL);
gtk_container_child_set (GTK_CONTAINER (hbox),
                         GTK_WIDGET (button),
                         "expand", FALSE,
                         "position", 0,
                         NULL);
