A couple of days ago, I've filled up a Qt Questionnaire and I've seen a couple of subjects that I need to revise. So, Here an Example of Flickr Downloader using QtConcurrent, High Level Network Operations (QNetworkManager), QGraphicsView and QDomElement.
The Flickr Service Class implements, only a couple of Methods. Request of Recently added and Interesting Photos, and the Search Photos Methods.
The Source Code is Available Here: QFlickr Test Source Code. (You Must Set your Flickr Key!)
