If that really bugs you, autoconnect connects the signal handler
swapping the user_data with the widget's instance, like if you would use
g_signal_connect_swapped () in your code to connect to that signal.
Whatever you can use as your user data with autoconnect is limited to
the individual widgets from your glade file. I advise against using
glade_xml_signal_autoconnect () for anything but simplest projects. Use
glade_xml_signal_connect_data () instead, when you need to pass
allocated data around.
