This will tell you if there's a selection, but what you really want to do is
connect a handler to the "changed" signal of the selection object.  See the
bottom of

http://developer.gnome.org/doc/API/2.0/gtk/GtkTreeSelection.html

for the prototype of the callback.  Then in your callback you'll use
get_selected to get the selected row itself.
