A utility for converting between std::vector and plain C arrays.
This would normally only be used by glibmm or gtkmm itself, or similar libraries that wrap C APIs.
For instance:
std::vector<Glib::ustring> PixbufFormat::get_mime_types() const { return Glib::ArrayHandler<Glib::ustring>::array_to_vector(gdk_pixbuf_format_get_mime_types(const_cast<GdkPixbufFormat*>(gobj())), Glib::OWNERSHIP_DEEP); }
or
void Display::store_clipboard(const Glib::RefPtr<Gdk::Window>& clipboard_window, guint32 time_, const std::vector<Glib::ustring>& targets) { if (!targets.size ()) { gdk_display_store_clipboard(gobj(), Glib::unwrap (clipboard_window), time_, Glib::ArrayHandler<Glib::ustring, AtomUstringTraits>::vector_to_array(targets).data (), targets.size ()); } }
Note that usage below is wrong - data() returns a pointer to data owned by a temporary ArrayKeeper returned by vector_to_array(), which is destroyed at the end of this instruction. For details, see Glib::ArrayKeeper.
const char** array = Glib::ArrayHandler<Glib::ustring>::vector_to_array(vec).data ();
