I thought of this function, but then I need to make it top-down. I can 
in no way just say that I want to see the page (and its parents) 
containing a specific widget?
I can probably use the gtk_widget_get_parent/gtk_widget_get_ancestor to 
find the parent notebook(s), so I try that even though it seems a little 
clumsy.

BTW When I used gtk_widget_get_ancestor(notebook1, GTK_TYPE_NOTEBOOK), I 
got the pointer equal to 'notebook1', not the parent notebook as I had 
expected. Is this the intended behaviour of gtk_widget_get_ancestor() or 
is it a simple bug? (It is easy to work around in a consistent way, so 
it is no big deal.)

It is 'any widget', so it can not be expected to be a clever widget :-)
But how do I get the position of the widget, so that I can set the 
adjustment?

Basicly what I have access to is the widget pointer. So I have to 
determine the position of the widget relative to the scrolled window 
somehow...??
