46 * GtkEntryCompletionMatchFunc:
47 * @completion: the #GtkEntryCompletion
48 * @key: the string to match, normalized and case-folded
49 * @iter: a #GtkTreeIter indicating the row to match
50 * @user_data: user data given to gtk_entry_completion_set_match_func()
51 *
52 * A function which decides whether the row indicated by @iter matches
53 * a given @key, and should be displayed as a possible completion for @key.
54 * Note that @key is normalized and case-folded (see g_utf8_normalize()
55 * and g_utf8_casefold()). If this is not appropriate, match functions
56 * have access to the unmodified key via
57 * `gtk_entry_get_text (GTK_ENTRY (gtk_entry_completion_get_entry ()))`.
58 *
59 * Returns: %TRUE if @iter should be displayed as a possible completion
60 * for @key
