Updating Gtk container when adding widgets

I've got some code which populates a GtkVBox with new widgets from some data, after the UI is initially built.

So there's some code which runs later looking something like this:

gchar* str = "something or other";
ascii_labels [i] = gtk_label_new (NULL);
gtk_label_set_markup (GTK_LABEL (ascii_labels [i]), str);

ascii_event_boxes [i] = gtk_event_box_new ();

gtk_container_add (GTK_CONTAINER (ascii_event_boxes [i]),
                   ascii_labels [i]);

gtk_box_pack_start (GTK_BOX (ascii_box),
                    ascii_event_boxes [i],
                    FALSE, FALSE, 0);

in some loop. A bit later I have

gtk_widget_show_all (ascii_box);

to set visibility. This seems to work, in that when I run the resulting application with GtkParasite, I can see the widgets nested correctly in the Widget Tree and they are set to be visible.

Unfortunately, they don't actually appear in the application's window! The reason I think I'm missing some sort of "update yourself please" call is that if I toggle the visibility of one of those widgets from the GtkParasite tool, all the other widgets that were missing magically appear!

Can anyone tell me what I'm missing?

The packing looks good, but what we need here is to know what ascii_labels contains, and how it's defined. The problem is not visibility, as gtk_widget_show_all takes care of that for you.
