This is how to set the function:
http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeSelection.html#gtk-tree-se
lection-set-select-function

NOTE: I have used this method before and each time the selection changes,
you do not get just ONE event (if memory serves).  You get events to state
that selection has changed for each item, for example, if you select item 2,
and item 1 was selected, you receive an event to state item 1 is now NOT
selected and item 2 now IS selected. 

This can be tricky, but should do what you want.
