.. class:: OptionFlags
   :no-contents-entry:






Flags which modify individual options.













Fields
------

.. rst-class:: interim-class

.. class:: OptionFlags
   :no-index:
   

   .. attribute:: FILENAME

      For options of the :const:`~gi.repository.GLib.OptionArg.CALLBACK`
      kind, this flag indicates that the argument should be passed to the
      callback in the GLib filename encoding rather than UTF-8. Since 2.8







   .. attribute:: HIDDEN

      The option doesn't appear in ``--help`` output.







   .. attribute:: IN_MAIN

      The option appears in the main section of the
      ``--help`` output, even if it is defined in a group.







   .. attribute:: NOALIAS

      This flag turns off the automatic conflict
      resolution which prefixes long option names with ``groupname-`` if
      there is a conflict. This option should only be used in situations
      where aliasing is necessary to model some legacy commandline interface.
      It is not safe to use this option, unless all option groups are under
      your direct control. Since 2.8.







   .. attribute:: NONE

      No flags. Since: 2.42.







   .. attribute:: NO_ARG

      For options of the :const:`~gi.repository.GLib.OptionArg.CALLBACK` kind,
      this flag indicates that the callback does not take any argument
      (like a :const:`~gi.repository.GLib.OptionArg.NONE` option). Since 2.8







   .. attribute:: OPTIONAL_ARG

      For options of the :const:`~gi.repository.GLib.OptionArg.CALLBACK`
      kind, this flag indicates that the argument supply is optional.
      If no argument is given then data of ``%GOptionParseFunc`` will be
      set to NULL. Since 2.8







   .. attribute:: REVERSE

      For options of the :const:`~gi.repository.GLib.OptionArg.NONE` kind, this
      flag indicates that the sense of the option is reversed. i.e. :const:`False` will
      be stored into the argument rather than :const:`True`.
