Detailed Description

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

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

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

For instance:

 std::vector< Glib::RefPtr<Window> > Window::get_children()
 {
   return Glib::ListHandler<Glib::RefPtr<Window> >::list_to_vector(gdk_window_get_children(gobj()), Glib::OWNERSHIP_SHALLOW);
 }

or

 void Window::set_icon_list(const std::vector< Glib::RefPtr<Gdk::Pixbuf> >& pixbufs)
 {
   gdk_window_set_icon_list(gobj(), Glib::ListHandler<Glib::RefPtr<Gdk::Pixbuf> >::vector_to_list(pixbufs).data ());
 }

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