disclaimer: i haven't actually done this, i'm just looking through the docs
for what looks like the relevant stuff given what i know about treeview.


some combination of $treeview->get_column(index) or $treeview->get_columns
will get you the column object(s) of interest.

if i'm reading correctly, $column->set_sort_column_id () will do what you
want, without the need to set up callbacks and such.

if not, you can call $column->set_clickable to make the column clickable, and
connect something to the clicked signal on $column.  from that signal handler
you'd use set_sort_indicator and set_sort_order, yadda yadda yadda.
