| 41 | * @title: Enumeration and Flag Types |
| 42 | * |
| 43 | * The GLib type system provides fundamental types for enumeration and |
| 44 | * flags types. (Flags types are like enumerations, but allow their |
| 45 | * values to be combined by bitwise or). A registered enumeration or |
| 46 | * flags type associates a name and a nickname with each allowed |
| 47 | * value, and the methods g_enum_get_value_by_name(), |
| 48 | * g_enum_get_value_by_nick(), g_flags_get_value_by_name() and |
| 49 | * g_flags_get_value_by_nick() can look up values by their name or |
| 50 | * nickname. When an enumeration or flags type is registered with the |
| 51 | * GLib type system, it can be used as value type for object |
| 52 | * properties, using g_param_spec_enum() or g_param_spec_flags(). |
| 53 | * |
| 54 | * GObject ships with a utility called <link |
| 55 | * linkend="glib-mkenums">glib-mkenums</link> that can construct |
| 56 | * suitable type registration functions from C enumeration |
| 57 | * definitions. |
