# With GTK+, for more GUIes coherency, GtkOptionMenu is recommended instead of a

# That is, non-editable combo boxes are not encouraged. GtkOptionMenu is much
# easier to use than GtkCombo as well. Use GtkCombo only when you need the
# editable text entry.
#
# GtkOptionMenu is a much better-implemented widget and also the right UI for
# noneditable sets of choices.)

# GtkList. GtkOption menu is deprecated in order to have an unified widget.
