 ~Object () noexcept override
Protected Member Functions inherited from Glib::ObjectBase
 ObjectBase ()
 This default constructor is called implicitly from the constructor of user-derived classes, even if, for instance, Gtk::Button calls a different ObjectBase constructor.
 ObjectBase (const char * custom_type_name)
 A derived constructor always overrides this choice.
 ObjectBase (const std::type_info & custom_type_info)
 This constructor is a special feature to allow creation of derived types on the fly, without having to use g_object_new() manually.
