Gtk.EntryCompletionMatchFunc

A function which decides whether the row indicated by iter matches a given key, and should be displayed as a possible completion for key. Note that key is normalized and case-folded (see GLib.utf8_normalize and GLib.utf8_casefold). If this is not appropriate, match functions have access to the unmodified key via <literal>gtk_entry_get_text (GTK_ENTRY (gtk_entry_completion_get_entry (<!-- -->)))</literal>.
