Я прочитал на хабре статью Как легко творить прекрасное и взял код из этой статьи за основу.
Была задача на сделать законченное приложение показывающее картинки из интернета и имеющее элементы управления.
"Прекрасное" с хабрахабра дало мне дополнительные силы и заставляло концентрироваться на документации.
Вот что из этого получилось.
Вся программа составляет примерно 290 срок.
Можно скопировать ее отсюда и вставить в новый проект Qt Creator, заменив содержимое main.qml
