forcing GtkText to always show last line.

[Bertrand Guiheneuf <Bertrand Guiheneuf inria fr>]

Hi,

Is there an (elegant) way to force GtkText to always show last inserted lines.

calling 
 gtk_adjustment_set_value(adj,adj->upper-adj->page_size);
just after inserting text does not work (it does not take newly inserted text 
into account).

Thanks in advance.
