Or go from scratch with socket() and Glib::IOChannel::create_from_fd() (IOChannels can call back when e.g. the HTTP response is arriving).
For the view, yes you can use a Gdk::Pixbuf: create a blank pixbuf and set it as the Gtk::Image's source, then render frames into the pixbuf (manipulating the guint8* RGB data returned by get_pixels() is fairly quick), calling image.queue_draw() after each frame. You may have to call image.set(pixbuf) after each frame as well, not sure if that's necessary. Good luck. _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
