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()
{
>::list_to_vector(gdk_window_get_children(gobj()), Glib::OWNERSHIP_SHALLOW);
}
A utility for converting between std::vector and GList.
Definition: vectorutils.h:530
static VectorType list_to_vector(GList *glist, Glib::OwnershipType ownership)
@ OWNERSHIP_SHALLOW
Definition: containerhandle_shared.h:52

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 ());
}
static GListKeeperType vector_to_list(const VectorType &vector)
RefPtr<> is a reference-counting shared smartpointer.
Definition: refptr.h:52

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.
