The QML docs needs a general guide on QML/C++ integration. Currently there is

• Using QML in C++ Applications - mainly focused on using context properties, and then has some info about network components and Qt resources
• Integrating QML with existing Qt UI code - only about integration with GraphicsView
• Extending QML in C++ - mainly a reference guide for writing extensions

There is no generic guide for beginners to QML/C++ integration. It looks like "Using QML in C++ Applications" should do this but it doesn't demonstrate essential concepts like invoking QML functions from C++ and vice versa.
