/** A list model for directory listings.
 *
 * %Gtk::DirectoryList is a list model that wraps Gio::File::enumerate_children_async().
 * It presents a Gio::ListModel and fills it asynchronously with the Gio::FileInfo%s
 * returned from that function.
 *
 * Enumeration will start automatically when the property_file() property
 * is set.
 *
 * While the %Gtk::DirectoryList is being filled, the property_loading()
 * property will be set to <tt>true</tt>. You can listen to that property if you want
 * to show information like a Gtk::Spinner or a "Loading..." text.
 *
 * If loading fails at any point, the property_error() property will be
 * set to give more indication about the failure.
 *
 * The Gio::FileInfo%s returned from a %Gtk::DirectoryList have the "standard::file"
 * attribute set to the Gio::File they refer to. This way you can get at the file
 * that is referred to in the same way you would via Gio::File::enumerator_get_child().
 * This means you do not need access to the %Gtk::DirectoryList but can access
 * the Gio::File directly from the Gio::FileInfo when operating with a Gtk::ListView
 * or similar.
