Life of Glib::OptionEntry objects

[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.
