在Scope利用Content sharing Widget来分享内容

在最新的Scope Widget中，有一个新的Content Sharing Widget．我们能够利用这个Widget来分享我们的图片到信息。Facebook，Twitter等渠道．比方，在我们的Scope Preview中，点击图片上的分享button。就能够把我们的内容分享出去．

它的设计也很easy明了．

我们还是从我们已经做过的练习中下载代码：

$ git clone https://github.com/liu-xiao-guo/scopetemplates_comment_input

１）加入新的图片资源

query.cpp

void Query::pushResult(sc::SearchReplyProxy const& reply,
                       const string renderer, int i) {
    stringstream ss;
    ss << i;
    string str = ss.str();

    auto cat = reply->register_category( "id" + str, "Template " + str ,
                                         "", sc::CategoryRenderer(renderer) );
    sc::CategorisedResult r(cat);
    r.set_uri( URI.toStdString() );
    r.set_art( images_[0].toStdString() );
//    r.set_art("http://api.map.baidu.com/images/weather/night/leizhenyu.png");
    r["subtitle"] = "Subtitle " + str;
    r.set_title("Title " + str);
    r["summary"] = "Summary: " + str;
    r["fulldesc"] = "fulldesc: " + str;
    r["mascot"] = icons_[0].toStdString();
    r["emblem"] = icons_[1].toStdString();
    r["background"] = background_.toStdString();
    r["overlay-color"] = "#FF0000";

    r["comment_icon"] = icons_[3].toStdString();
    r["share_icon"] = icons_[4].toStdString();
    r["share_pic"] = icons_[5].toStdString();

    QString likes = QString("%1 %2").arg(qstr(u8"\u261d "), "100");
    QString views = QString("%1 %2").arg(qstr(u8"   \u261f "), "99");
    std::string both = qstr("%1 %2").arg(likes,views).toStdString();
    sc::VariantBuilder builder;
    builder.add_tuple({
        {"value", Variant(both)}
    });
    builder.add_tuple({
        {"value", Variant("")}
    });
    r["attributes"] = builder.end();

    r["musicSource"] = "http://qqmp3.djwma.com/mp3/魔音神据极品私货这锯子拉的耳膜都要碎了.mp3";
    r["videoSource"] = "http://techslides.com/demos/sample-videos/small.mp4";
    r["screenshot"] = icons_[2].toStdString();

    // add an array to show the gallary of it
    sc::VariantArray arr;

    for(const auto &datum : icons_) {
        arr.push_back(Variant(datum.toStdString()));
    }

    r["array"] = sc::Variant(arr);

    if (!reply->push(r))
        return;
}

void Query::pushResult(sc::SearchReplyProxy const& reply,
                       const std::shared_ptr<const Category> *cat, int i) {

    stringstream ss;
    ss << i;
    string str = ss.str();

    sc::CategorisedResult r(*cat);
    r.set_uri( URI.toStdString() );
    r.set_art( images_[i].toStdString() );
    r["subtitle"] = "Subtitle " + str;
    r.set_title("Title " + str);
    r["summary"] = "Summary: " + str;
    r["fulldesc"] = "fulldesc: " + str;
    r["mascot"] = icons_[0].toStdString();
    r["emblem"] = icons_[1].toStdString();

    r["comment_icon"] = icons_[3].toStdString();
    r["share_icon"] = icons_[4].toStdString();
    r["share_pic"] = icons_[5].toStdString();

    QString likes = QString("%1 %2").arg(qstr(u8"\u261d "), "100");
    QString views = QString("%1 %2").arg(qstr(u8"   \u261f "), "99");
    std::string both = qstr("%1 %2").arg(likes,views).toStdString();
    sc::VariantBuilder builder;
    builder.add_tuple({
        {"value", Variant(both)}
    });
    builder.add_tuple({
        {"value", Variant("")}
    });
    r["attributes"] = builder.end();

    r["musicSource"] = "";
    r["videoSource"] = "";
    r["screenshot"] = "";
    // This is to ensure that the preview can well for the grid/carousel/lists...
    VariantArray arr;
    r["array"] = sc::Variant(arr);;

    if (!reply->push(r))
        return;
}

在上面我们加入了两个新的图片：

    r["share_icon"] = icons_[4].toStdString();
    r["share_pic"] = icons_[5].toStdString();

注意这里的＂share_icon＂是在Preview窗体中显示的图片．它能够和我们实际分享的照片是不一样的．在＂share_pic＂中真正定义的是我们想要分享的图片．在实际的应用中。被分享的图片也能够是一个数组．请开发人员自己參考我们的文档来实践．

２）在Preview中加入我们的Widget

preview.cpp

void Preview::run(sc::PreviewReplyProxy const& reply) {
    Result result = PreviewQueryBase::result();

    ColumnLayout layout1col(1);
    std::vector<std::string> ids = { "image", "header", "summary", "tracks",
                                    "videos", "gallery_header", "gallerys", "reviews", "exp",
                                     "review_input", "rating_input", "inputId", "img" };
//    std::vector<std::string> ids = { "inputId", "img" };

    PreviewWidgetList widgets;

    ColumnLayout layout2col(2);
    layout2col.add_column(ids);
    layout2col.add_column({});

    ColumnLayout layout3col(3);
    layout3col.add_column(ids);
    layout3col.add_column({});
    layout3col.add_column({});

    // Define the header section
    sc::PreviewWidget header("header", "header");
    // It has title and a subtitle properties
    header.add_attribute_mapping("title", "title");
    header.add_attribute_mapping("subtitle", "subtitle");
    widgets.emplace_back(header);

    // Define the image section
    sc::PreviewWidget image("image", "image");
    // It has a single source property, mapped to the result's art property
    image.add_attribute_mapping("source", "art");
    widgets.emplace_back(image);

    // Define the summary section
    sc::PreviewWidget description("summary", "text");
    // It has a text property, mapped to the result's description property
    description.add_attribute_mapping("text", "description");
    widgets.emplace_back(description);

    PreviewWidget listen("tracks", "audio");
    {
        VariantBuilder builder;
        builder.add_tuple({
            {"title", Variant("This is the song title")},
            {"source", Variant(result["musicSource"].get_string().c_str())}
        });
        listen.add_attribute_value("tracks", builder.end());
    }

    PreviewWidget video("videos", "video");
    video.add_attribute_value("source", Variant(result["videoSource"].get_string().c_str()));
    video.add_attribute_value("screenshot", Variant(result["screenshot"].get_string().c_str()));

    PreviewWidget header_gal("gallery_header", "header");
    header_gal.add_attribute_value("title", Variant("Gallery files are:"));

    PreviewWidget gallery("gallerys", "gallery");
    gallery.add_attribute_mapping("sources", "array");

    if ( result["musicSource"].get_string().length() != 0 ) {
        widgets.emplace_back(listen);
    }

    if( result["videoSource"].get_string().length() != 0 ) {
        widgets.emplace_back(video);
    }

    if( result["array"].get_array().size() != 0 ) {
        widgets.emplace_back(header_gal);
        widgets.emplace_back(gallery);
    }

    // The following shows the review
    PreviewWidget review("reviews", "reviews");
    VariantBuilder builder;
    builder.add_tuple({
                          {"author", Variant("John Doe")},
                          {"review", Variant("very good")},
                          {"rating", Variant(3.5)}
                      });
    builder.add_tuple({
                          {"author", Variant("Mr. Smith")},
                          {"review", Variant("very poor")},
                          {"rating", Variant(5)}
                      });
    review.add_attribute_value("reviews", builder.end());
    widgets.emplace_back(review);

    // The following shows the expandable
    PreviewWidget expandable("exp", "expandable");
    expandable.add_attribute_value("title", Variant("This is an expandable widget"));
    expandable.add_attribute_value("collapsed-widgets", Variant(1));
    PreviewWidget w1("w1", "text");
    w1.add_attribute_value("title", Variant("Subwidget 1"));
    w1.add_attribute_value("text", Variant("A text"));
    PreviewWidget w2("w2", "text");
    w2.add_attribute_value("title", Variant("Subwidget 2"));
    w2.add_attribute_value("text", Variant("A text"));
    expandable.add_widget(w1);
    expandable.add_widget(w2);
    widgets.emplace_back(expandable);

    // 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);

    PreviewWidget w_image("img", "image");
    w_image.add_attribute_value("source", Variant(result["share_icon"].get_string().c_str()));
    VariantMap share_data;
//    share_data["uri"] = Variant("http://img2.imgtn.bdimg.com/it/u=442803940,143587648&fm=21&gp=0.jpg");
    share_data["uri"] = Variant(result["share_pic"].get_string().c_str());
    share_data["content-type"] = Variant("pictures");
    w_image.add_attribute_value("share-data",  sc::Variant(share_data));
    widgets.emplace_back(w_image);

    PreviewWidget w_commentInput("inputId", "comment-input");
    w_commentInput.add_attribute_value("submit-label", Variant("Post"));
    widgets.emplace_back(w_commentInput);

    // In the following, fake some comments data
    QList<Comment> comment_list;
    std::string comment_str = "Comment ";
    for(int i = 0; i < 3;  i++) {
        Comment comment;

        comment.id         = 1.0;
        comment.publishTime = "2015-3-18";
        comment.text = comment_str;
        comment.text += std::to_string(i+1);
        comment_list.append(comment);
    }

    int index = 0;
    Q_FOREACH(const auto & comment, comment_list) {
        std::string id = "commentId_" + std::to_string(index++);
        ids.emplace_back(id);

        PreviewWidget w_comment(id, "comment");
        w_comment.add_attribute_value("comment", Variant(comment.text));
        w_comment.add_attribute_value("author", Variant("Author"));
        w_comment.add_attribute_value("source", Variant(result["comment_icon"].get_string().c_str()));
        w_comment.add_attribute_value("subtitle", Variant(comment.publishTime));
        widgets.emplace_back(w_comment);
    }

    layout1col.add_column(ids);
    reply->register_layout({layout1col, layout2col, layout3col});
    reply->push( widgets );
}

在上面的代码中，我们加入了

    PreviewWidget w_image("img", "image");
    w_image.add_attribute_value("source", Variant(result["share_icon"].get_string().c_str()));
    VariantMap share_data;
//    share_data["uri"] = Variant("http://img2.imgtn.bdimg.com/it/u=442803940,143587648&fm=21&gp=0.jpg");
    share_data["uri"] = Variant(result["share_pic"].get_string().c_str());
    share_data["content-type"] = Variant("pictures");
    w_image.add_attribute_value("share-data",  sc::Variant(share_data));
    widgets.emplace_back(w_image);

同一时候。我们也在以下的Ids中加入了新添加的img ID:

    std::vector<std::string> ids = { "image", "header", "summary", "tracks",
                                    "videos", "gallery_header", "gallerys", "reviews", "exp",
                                     "review_input", "rating_input", "inputId", "img" };

通过这个方案，当我们的照片被显示时。在图片的左下方就会出现一个分享的button．

点击我们的button就能够把我们在上面＂share_pic＂中定义的照片分享出去．这个照片也能够是网路上的一张照片．
