#### Description

    struct GActionEntry {
      const gchar* name;
      void (* activate) (
        GSimpleAction* action,
        GVariant* parameter,
        gpointer user_data
      );
      const gchar* parameter_type;
      const gchar* state;
      void (* change_state) (
        GSimpleAction* action,
        GVariant* value,
        gpointer user_data
      );
    }

This struct defines a single action. It is for use with g_action_map_add_action_entries().

The order of the items in the structure are intended to reflect frequency of use. It is permissible to use an incomplete initialiser in order to leave some of the later values as `NULL`. All values after `name` are optional. Additional optional fields may be added in the future.

See `g_action_map_add_action_entries()` for an example.

###### Structure members

`name`

  The name of the action.

`activate`
  No description available.
`parameter_type`

  The type of the parameter that must be passed to the activate function for this action, given as a single GVariant type string (or `NULL` for no parameter)

`state`

  The initial state for this action, given in [GVariant text format][gvariant-text]. The state is parsed with no extra type information, so type tags must be added to the string if they are necessary. Stateless actions should give `NULL` here.

`change_state`
  No description available.
