Automagic scrolling scrollwindow

[David Kinyanjui <david i2software com>]

I don't know if my brains are in a blackout or I'm just dumb!
I need to implement the following:
gtk_container_set_focus_vadjustment (GtkContainer *container, 
GtkAdjustment *adjustment);

I need someone to provide me with an example on how to implement this.
OR
Any other example on how to automagically scroll the scrollbars 
(especially the vertical one) in a scrolledwindow.

Thanks in advance
