tree-selection-set-select-function
http://developer.gnome.org/doc/API/2.0/gtk/ 
GtkTreeSelection.html#GtkTreeSelectionFunc

translates to perl as:

  $treeview->get_selection->set_select_function (\&selectable_filter);

  sub selectable_filter {
      my ($selection, $model, $path, $is_path_currently_selected) = @_;
      # return true if the selection state can be toggled
      return rand(10) > 5;
  }
