I think I prefer the old formulation of:

if (i < display_results.size()) {
  result_view->SetResult(display_results[i]);
  result_view->SetVisible(true);
} else {
  result_view->SetResult(NULL);
  result_view->SetVisible(false);
}

It's clearer than inventing a new variable just to write it conditionally, and
then act on it conditionally.

Done.

+      item = display_results[i];
+
+    result_view->SetResult(item);
+    result_view->SetVisible(item != NULL);
   }
   if (selected_index_ > last_visible_index_)
     SetSelectedIndex(last_visible_index_);
