在先前的文章“利用reviews PreviewWidget在Ubuntu Scope中显示评价等级”中，我们展示了如何使用review PreviewWidget来显示评价的数据。在这篇文章中，我们将介绍如何使用rating-input PreviewWidget来对事物进行评价及打分。
参考我们的API介绍，rating-input PreviewWidget分为两种：
// The following shows a review rating-input
PreviewWidget w_review("review_input", "rating-input");
w_review.add_attribute_value("submit-label", Variant("Send"));
w_review.add_attribute_value("visible", Variant("review"));
w_review.add_attribute_value("required", Variant("review"));
std::string reply_label = "Reply";
std::string max_chars_label = "140 characters max";
w_review.add_attribute_value("review-label", Variant(reply_label + ": " + max_chars_label));
widgets.emplace_back(w_review);
// The follwing shows a rating rating-input
PreviewWidget w_rating("rating_input", "rating-input");
w_rating.add_attribute_value("visible", Variant("rating"));
w_rating.add_attribute_value("required", Variant("rating"));
w_rating.add_attribute_value("rating-label", Variant("Please rate this"));
widgets.emplace_back(w_rating);
