A few gtk/glib related questions

[galtgendo o2 pl]

What would be the correct way of removing all rows from a text combobox, 
as I'm trying not to use a full combobox. Now I'm thinking about 
something along the lines of:

i = gtk_tree_model_iter_n_children (gtk_combo_box_get_model(combobox), 
NULL);
while (i>0) {i--; gtk_combo_box_remove_text(combobox, i);}

but I want to make sure that's correct.

Next question: when going from GnomeUIInfo to GtkUIManager stock menu 
items stay translated, but is there a way to do it for menus (File, 
Edit, etc.)?
Finally, what are the important differences between using 
AM_GNU_GETTEXT([external]) and AM_GLIB_GNU_GETTEXT ?

And yeah, I still think that having no other way than 
gtk_rc_parse_string of forcing combobox to become a list really sucks.
