Could you tell me why you double define connector_moved? I haven't
written yet any GTK programm (just keep listening and when the time
comes ... :-)) but in which the above is different from
gtk_signal_connect_object (GTK_OBJECT(node1), "moved",
			GTK_SIGNAL_FUNC(connector_moved),
			GTK_OBJECT(connector));
gtk_signal_connect_object (GTK_OBJECT(node2), "moved",
			GTK_SIGNAL_FUNC(connector_moved),
			GTK_OBJECT(connector));
static void
connector_moved (Connector *conn, gdouble dx, gdouble dy, Node *node)
{
    connector_move_point (conn, get_connection_id(conn, node));
}

The answer: "RTFM _link_to_the_fine_manual_" will do :)).
