    Any widget that contains another widget is a GtkContainer, it is
possible that (GTK_IS_BIN(GTK_CONTAINER(widget)) == TRUE), in that case
there is only one child which you can retrieve with `gtk_bin_get_child()'
but you should be able to retrieve it with `gtk_container_get_children()'
anyway, only you will have a one element `GList *' (assuming that GtkBin
behaves properly when you call its
`GTK_CONTAINER_GET_CLASS(gtk_bin)->get_children()' method.

I hope this is enlightening for you :-P
