Scroll to bottom of window...

["David Conley (FRD)" <dconley frd co uk>]

I'm trying to write a app that has a small text window that fills with 
text from another thread. Its all working fine but the text is dropping 
off the end of the window. Really what I'd like is for the scroll window 
the text view is in to automatically scroll to the bottom to show the 
latest message added. I suspect I need to use
gtk_scrolled_window_set_vadjustment(GTK_SCROLLED_WINDOW(scroll), adj);
but what I set my adjustment to I have no idea. Anyone got any tips.
Thanks
