Detailed Description

template<typename T, typename Tr = Glib::Container_Helpers::TypeTraits<T>>
class Glib::SListHandler< T, Tr >

A utility for converting between std::vector and GSList.

This would normally only be used by glibmm or gtkmm itself, or similar libraries that wrap C APIs.

For instance:

std::vector< Glib::RefPtr<Display> > DisplayManager::list_displays()
{
  return Glib::SListHandler<Glib::RefPtr<Display>
>::slist_to_vector(gdk_display_manager_list_displays(gobj()), Glib::OWNERSHIP_SHALLOW);
}

or

void Stuff::set_slist(const std::vector<int>& ints)
{
  g_stuff_set_slist(gobj(), Glib::SListHandler<int>::vector_to_slist(ints).data ());
}

Note that usage below is wrong - data() returns a pointer to data owned by a temporary SListKeeper returned by vector_to_slist(), which is destroyed at the end of this instruction. For details, see Glib::SListKeeper.

GSList* gslist = Glib::SListHandler< Glib::RefPtr<Display> >::vector_to_slist(vec).data();
