Making a sortable list

["Andersen, Jan" <jandersen informatica com>]

How do I make a list sortable - so that when I click the column header, the list is sorted by that column?

I have a GtkListStore displayed by a GtkTreeView, but the documentation gets a bit abstract on the point of sorting things and doesn't really clarify matters much beyond telling that it is 'trivial', which I suppose is a good thing.
