Actually, this code is not directly from glade-2, but created on the
fly via some code orginally adapted from glade (I basically changed
the variable names, and c99-ified it). I'm using stock gtk from Fedora
Core 4 and don't appear to have glade3.

Here is the snippet that creates the expander:

    GtkWidget *expander = gtk_expander_new(NULL);
    gtk_expander_set_expanded(GTK_EXPANDER(expander), TRUE);
    gtk_box_pack_start(GTK_BOX(plots), expander, FALSE, FALSE, 0);
    
    GtkWidget *hbox = gtk_hbox_new(FALSE, 0);
    gtk_expander_set_label_widget(GTK_EXPANDER(expander), hbox);

    GtkLabel *label = GTK_LABEL(gtk_label_new(plotname));
    gtk_box_pack_start(GTK_BOX(hbox), GTK_WIDGET(label), TRUE, TRUE, 0);
    gtk_widget_set_sensitive(GTK_WIDGET(label), TRUE);

    GtkWidget *edit_button = gtk_button_new_with_mnemonic("Edit");
    gtk_box_pack_start(GTK_BOX(hbox), edit_button, FALSE, FALSE, 0);
    gtk_widget_set_sensitive(edit_button, TRUE);
    g_signal_connect(edit_button, "clicked",
                     G_CALLBACK(EditPlot), 
                     (gpointer)p);

    GtkWidget *delete_button = gtk_button_new_with_mnemonic("Delete");
    gtk_box_pack_start(GTK_BOX(hbox), delete_button, FALSE, FALSE, 0);
    gtk_widget_set_sensitive(delete_button, TRUE);
    g_signal_connect(delete_button, "clicked",
                     G_CALLBACK(DeletePlot), 
                     (gpointer)p);

    GtkWidget *vbox = gtk_vbox_new(FALSE, 0);
    gtk_container_add(GTK_CONTAINER(expander), vbox);
    // ... put some junk in the vbox

Any help you could provide would be greatly appreciated.
