Details¶

class GLib.OptionGroup¶

A GOptionGroup struct defines the options in a single group. The struct has only private fields and should not be directly accessed.

All options in a group share the same translation function. Libraries which need to parse commandline options are expected to provide a function for getting a GOptionGroup holding their options, which the application can then add to its GLib.OptionContext.

classmethod new(name, description, help_description, user_data, destroy)[source]¶

Parameters:

name (str) – the name for the option group, this is used to provide help for the options in this group with --help- name
description (str) – a description for this group to be shown in --help. This string is translated using the translation domain or translation function of the group
help_description (str) – a description for the --help- name option. This string is translated using the translation domain or translation function of the group
user_data (object or None) – user data that will be passed to the pre- and post-parse hooks, the error hook and to callbacks of GLib.OptionArg.CALLBACK options, or None
destroy (GLib.DestroyNotify or None) – a function that will be called to free user_data, or None

Returns:

a newly created option group. It should be added to a GLib.OptionContext or freed with GLib.OptionGroup.unref().

Return type:

GLib.OptionGroup

Creates a new GLib.OptionGroup.

description is typically used to provide a title for the group. If so, it is recommended that it’s written in title case, and has a trailing colon so that it matches the style of built-in GLib group titles such as ‘Application Options:’.

New in version 2.6.

add_entries(entries)[source]¶

Parameters:: entries ([GLib.OptionEntry]) – a None-terminated array of GLib.OptionEntrys

Adds the options specified in entries to self.

New in version 2.6.

free()[source]¶: Frees a GLib.OptionGroup. Note that you must not free groups which have been added to a GLib.OptionContext.

New in version 2.6.

Deprecated since version 2.44: Use GLib.OptionGroup.unref() instead.

ref()[source]¶

Returns:: a GLib.OptionGroup
Return type:: GLib.OptionGroup

Increments the reference count of self by one.

New in version 2.44.

set_translate_func(func, *data)[source]¶

Parameters:

func (GLib.TranslateFunc or None) – the GLib.TranslateFunc, or None
data (object or None) – user data to pass to func, or None

Sets the function which is used to translate user-visible strings, for --help output. Different groups can use different GLib.TranslateFuncs. If func is None, strings are not translated.

If you are using gettext(), you only need to set the translation domain, see GLib.OptionGroup.set_translation_domain().

New in version 2.6.

set_translation_domain(domain)[source]¶

Parameters:: domain (str) – the domain to use

A convenience function to use gettext() for translating user-visible strings.

New in version 2.6.

unref()[source]¶: Decrements the reference count of self by one. If the reference count drops to 0, the self will be freed. and all memory allocated by the self is released.

New in version 2.44.
