GtkWidgets has already support for center on focused objects (I hope
that your "active" means that).

The implementation of this feature are related with this functions and

Anyway, as you are using a common GtkScrolledWindow, probably you only
require to use the function:

LibgnomeUI has a example. It has a GtkScrolledWindow, and inside a
hbox with several buttons. Each time you click on the button, the
scrolled window centers on it.

The example is libgnomeui-2.24.1/test-gnome/testgnome.c
(I got the code using "apt-get source libgnomeui", so probably you can too)

I hope this helps.
