Detailed Description

template<typename T>
class Gtk::EnumList< T >

A Gio::ListModel representing values of a given enum.

Gtk::EnumList contains items of type Gtk::EnumListItem.

A simple way to use a Gtk::EnumList is to populate a Gtk::DropDown widget using the short name (or "nick") of the values of an enumeration type:

Glib::RefPtr<Gtk::EnumList<Gtk::Justification>> enum_list =
  Gtk::EnumList<Gtk::Justification>::create();
Glib::RefPtr<Gtk::PropertyExpression> expression =
  Gtk::PropertyExpression<Glib::ustring>::create(Gtk::EnumListItem::get_type(), "nick");
Gtk::DropDown* drop_down = Gtk::make_managed<Gtk::DropDown>(enum_list, expression);

All variables in the code snippet can be declared auto. The full types are shown to make it clear what they are.
