  $cell = ($slist->get_column ($index)->get_cell_renderers)[0];
  $cell->signal_connect (toggled => sub {
        my ($cell, $text_path) = @_;
        print "toggled to ".($cell->get_active ? "on" : "off")."\n";
        # note: depending on how you connect the signal,
        # the model may or may not have been updated
        # when this handler runs.
  });


If the checkboxes are the only editable cells in each row, then you 
know that any change happening to the row is the result of the user 
toggling the checkbox.  In this case, it's simpler to do:

  $slist->get_model->signal_connect (row_changed => sub {
      my ($model, $path, $iter) = @_;
  })
