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.
GList* glist = Glib::ListHandler<Glib::RefPtr<Gdk::Pixbuf> >::vector_to_list(pixbufs).data();

| Glib::OwnershipType | ownership | ||
