Working with editable cellrenderertext pygtk, obviously missing something?

[Karl Lattimer <karl qdh org uk>]

I'm trying to put together a small editable treeview using the
gtk.CellRendererText and setting it editable following the FAQ guide
here; http://faq.pygtk.org/index.py?req=show&file=faq13.010.htp

My code currently looks like this;

renderer = gtk.CellRendererText()
renderer.connect('edited', self.on_tv_cell_edited)
renderer.set_property('editable', True)
treeview.insert_column_with_attributes(-1, 'Min', renderer, text=0)
treeview.insert_column_with_attributes(-1, 'Max', renderer, text=1)
model = gtk.TreeStore(gobject.TYPE_INT, gobject.TYPE_INT)
treeview.set_model(model)
tviter = model.append(None)
model.set_value(tviter, 0, 1)
model.set_value(tviter, 1, 5)

and the callback is like this;

def on_tv_cell_edited( self, renderer, path, value ):
  print path
  print value

But I can't seem to determine any method of identifying which cell value
corresponds to. Do I need to have separate renderers for each column and
set different signals for those columns?
