gtk_combo_box_entry_new_with_model

["Fabien Vantard" <fzzzzz gmail com>]

hi all,

I'm currently writing a part of code using
gtk_combo_box_entry_new_with_model feature. (See attachment). I'm
wondering if there is a way to make unselectable (and not displaying
it) the parent element. (example in attachment : only displaying 'A -
B' in menu and not in submenu.)

Attachment example is based on 'Combo boxes' example of gtk-demo
program with replacing a gtk_combo_box_new_with_model  by a
gtk_combo_box_ENTRY_new_with_model .

regards.
