Well, yes, maybe I am more confused than you, but I believe that
gtk_widget_show_all() in gtknotebooks doesn't show the notebook labels,
which it's a bit strange (but maybe only a lack of documentation about
which are the children of the notebook as a container).
By the way, another problem related to notebooks:
Putting eventboxes as labels of notebooks cause strange things. For example
when you press on the eventbox label, the label doesn't get selected.
Does anybody know if the notebook widget has or should have any technical
problems managing this correctly?
