使い方

xxxxxx.jsonは、各自UIEditorで作成してExportしたもの。

auto layout = GUIReader::getInstance()->widgetFromJsonFile("xxxxxx.json");
auto button = dynamic_cast<Button*>(WidgetUtil::getChildByNameRecursion(layout, "xxxxx_button"));
button->addTouchEventListener([](Ref *ref, Widget::TouchEventType type) {
    if (type == Widget::TouchEventType::ENDED) {
        // 処理
        CCLOG("xxxxx_button touch end");
    }
});
