## Detailed Description

An OptionGroup defines the options in a single group.

Libraries which need to parse commandline options are expected to provide a function that allows their OptionGroups to be added to the application's OptionContext.

## Constructor & Destructor Documentation

Glib::OptionGroup::OptionGroup | ( | const Glib::ustring& | name,
|  | const Glib::ustring& | description,
|  | const Glib::ustring& | help_description = `Glib::ustring()` |
| ) |  |  |

Glib::OptionGroup::OptionGroup | ( | GOptionGroup * | castitem | ) | `[explicit]`

This always takes ownership of the underlying GOptionGroup, so it is only useful with C functions that return newly-allocated GOptionGroups.

virtual Glib::OptionGroup::~OptionGroup | ( |  | ) | `[virtual]`
