<para>
|
||||
The GLib type system provides fundamental types for enumeration and flags types. (Flags types
|
||||
are like enumerations, but allow their values to be combined by bitwise or). A registered
|
||||
enumeration or flags type associates a name and a nickname with each allowed value, and
|
||||
the methods g_enum_get_value_by_name(), g_enum_get_value_by_nick(), g_flags_get_value_by_name()
|
||||
and g_flags_get_value_by_nick() can look up values by their name or nickname.
|
||||
When an enumeration or flags type is registered with the GLib type system, it can
|
||||
be used as value type for object properties, using g_param_spec_enum() or
|
||||
g_param_spec_flags().
