Thanks for the answer but that is what I tried.  It only moved the 
scrollbar part way as so.
Before setting the value of Gtk::Range.
Gtk::Adjustment.upper returned 255.

After calling this line of code.
Gtk::Range.value = Gtk::Adjustment.upper
Gtk::Adjustment.upper returned 15.


I just found the answer and it was pretty clear when I gave it some 
thought.  To move the scrollbar all the way to the other side(or bottom) 
use Gtk::ScrolledWindow.hscrollbar/vscrollbar.adjustment.inverted = 
true.  Since the scrollbar starts at 0 and this setting will make the 
oppostie end of the scrollbar 0, it will move the slider to the 
end/bottom.  I also noticed that anytime text is appended the scrollbar 
will stay at the end/bottom.


Thanks for the help,


Carl
