GtkArgFlags is deprecated and should not be used in newly-written code.
Possible flags indicating how an argument should be treated. Deprecated in favor of GParamSpec features.
|1||Gtk::ARG_READABLE||The argument is readable. (i.e. can be queried).|
|2||Gtk::ARG_WRITABLE||The argument is writable. (i.e. settable).|
|4||Gtk::ARG_CONSTRUCT||The argument needs construction.|
|8||Gtk::ARG_CONSTRUCT_ONLY||The argument needs construction (and will be set once during object creation), but is otherwise cannot be set. Hence this flag is not allowed with Gtk::ARG_WRITABLE, and is redundant with Gtk::ARG_CONSTRUCT.|
|16||Gtk::ARG_CHILD_ARG||An argument type that applies to (and may be different for) each child. Used by GtkContainer.|
