I solve it by 1) allocating a struct (then you should use the _full connect
function and pass g_free as the desroy handler) 2) setting named data on the
object I'm connecting the singal on e.g.

/*in signal handler*/
char *data1 = gtk_object_get_data(object,"data1");
GtkWidget *data2 = gtk_object_get_data(object,"data2");

/*when connecting
char *data1;
GtkWidget *data2;
...
gtk_object_set_data(object,"data1",data1);
gtk_object_set_data(object,"data2",data2);
gtk_signal_connect(object,"some_signal",GTK_SIGNAL_FUNC(handler),NULL);


This seems to meto be cleaner then defining a new struct, but I've been
accused in the past of liking _get/_set_data WAAAAY too much :)
