listbox.anyobj(0, 0, 20);
5. listbox is a widget_object, with template parameters drawerbase::listbox::trigger and drawerbase::listbox::scheme
amon others.
That means that listbox have a member trigger_ constructed first and accecible with get_drawer_trigger() and
a member (unique pointer to) scheme_ accesible with scheme_type& scheme() created in the constructor
with API::dev::make_scheme<Scheme>() which call API::detail::make_scheme(::nana::detail::scheme_factory<Scheme>())
which call restrict::bedrock.make_scheme(static_cast<::nana::detail::scheme_factory_base&&>(factory));
which call pi_data_->scheme.create(std::move(factory));
which call factory.create(scheme_template(std::move(factory)));
which call (new Scheme(static_cast<Scheme&>(other)));
and which in create is setted with: API::dev::set_scheme(handle_, scheme_.get()); which save the scheme pointer in
the nana::detail::basic_window member pointer scheme
\todo doc: actualize this example listbox.at(0)...
