[Gtk-sharp-list] [Mono GTK#] Bind Object List to ComboBox

[Jay Spencer]

That should work quite well...especially as the list is short...

Further in my project I deserialize a xml file into a list object class and
will need to populate a combobox as well...again no problem with winforms...

Could I do a foreach loop and populate the list store like that...

So from the class into the listview via a foreach loop ?
