Nokia have recently posted a set of QTQuick examples on Forum.Nokia. It’s a fantastic set of resources for developers looking into the platform and contains project files and source code, plus working demo’s on Windows, Maemo and Symbian. The QT Quick Playground also contains a code viewer bit so you can view and edit code on the fly.
You can get all the details at Forum.Noka through the link below.
I seriously recommend checking this one out.
