Glib::OptionEntry lifespan

[Matt Bucknall <matt mattbucknall com>]

Hi,

Do Glib::OptionEntry objects that have been added to a Glib::OptionGroup object get copied, or do they have to exist for as long as the Glib::OptionGroup object exists (in much the same way Glib::OptionGroup objects have to exist for the lifetime of a Glib::OptionContext object)?

Thanks,
Matt.
