I have a gtk.ScrolledWindow, which has a gtk.VBox added with a
gtk.Viewport.
What I would like to do is be able to scroll the gtk.ScrolledWindow to
a specific location (one of the gtk.VBox children). I know how to do
the actual scrolling (using the h/vadjustments) but how do I determine
how much to scroll it by so the correct child is in view?
Thanks for the help?
Does this help you:

How do I adjust a ScrolledWindow to adjust to a given child widget?
One common request is to get a ScrolledWindow to adjust to display one
of the widgets it contains -- frequently you'd like to adjust the
scrollbar to display the widget that receives focus. This is possible by
using the set_value method of the ScrolledWindow's adjustment object in
conjunction with the child widget's `focus_in_event' signal. An
(untested) example follows:
def focus_in(widget, event, adj):
alloc = widget.get_allocation()
if alloc.y < adj.value or alloc.y > adj.value + adj.page_size:
adj.set_value(min(alloc.y, adj.upper-adj.page_size))
scrolled_window = gtk.ScrolledWindow()
adj = scrolled_window.get_vadjustment()
# ... create child widget
child.connect('focus_in_event', focus_in, adj)
This should make the scrollbar adjust automatically whenever child
receives focus.
