My understanding is that QML describes the interface, but the actual application logic is written in something else. From Ubuntu's developer portal: > While Ubuntu and the applications that come with Ubuntu are written in many different languages, from C to Java to Haskell, when writing something new we recommend using Python. Many important parts of Ubuntu are already written directly in Python, and we work to make every important API and framework within Ubuntu available from Python. Python includes a rich standard library and a vast set of third party modules, so there are libraries available for just about everything you can think of. http://developer.ubuntu.com/resources/programming-languages/python/ http://developer.ubuntu.com/resources/programming-languages/... I've not gotten far into it though, and likely won't for a month or two. My experience lies almost completely on the web; I've never written a native mobile app or released desktop software.
