gtk_tree_view_scroll_to_cell() for the win!

http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeView.html#gtk-tree- 
view-scroll-to-cell


Make sure not to pass undef for the column, e.g.

   # we're already on the row, so just make sure this column is visible
   $tree_view->scroll_to_cell (undef, $column, FALSE, 0.0, 0.0);


Remember that you can get the column, if you don't already have it,  
by asking for it:

   $column = $tree_view->get_column ($index);
