Thanks for the help.   I still trying to get it going without much luck 
:(. I think the scroll to cell will work,
though i am having problems extracting the treeview from a gtkcombobox, 
and modifying the gtk
code so far has been unadventful for me so far.  Its weird though 
because gtk_tree_view_set_selection is
called in the gtk code but it isn't highlighting. Maybe its a styling 
thing.  I really havn't played with gtk
enough to know its internals.  I'll ask on the gtk-app-devel list, maybe 
someone has experence with
GtkComboBox and selections etc.
