Is there a way to create GtkComboBox menus with submenus?
The logical way to achieve this would be to use a GtkTreeStore model,
and indeed it works as expected,
except that each first level item appears also as a second level title,
that can be selected...
disabling a first level item disables the whole subtree, so this cannot
be used to disable the second level titles...
Or the only solution is to use
gtk_combo_box_set_wrap_width (GTK_COMBO_BOX (combo), width)
with width > 1? My data has some nice structure, so the submenus
approach looks slightly better...
Cheers,
Carlos
