It doesn't seem clear what I was trying to say about lists not "storing" references. I guess what I was trying to say is that I think trying to extract a reference by dereferencing a list<>::iterator is not doable. I was also trying to suggest another way get at the contents of the list. There are other ways to access the list, of course. std::list<>::pop_front(), for example, removes the first element of the list and std::list<>::front() does in fact return a reference so it would be fine to initialize a Glib::RefPtr<>& with the result from that. I'm sure you probably know all this, but in case you don't I might as well add this comment in case it helps further. Also, from the docs, a std::vector can be used instead of std::list. Finally, another element you might consider when working with volume control is the Gst::Volume plug-in. According to the docs here: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-volume.html It allows the control of the volume of audio through a pipeline. I hope this all might be useful. -- José _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
