Comunication from C++ and Qml interface

[mikecurl91]

Hi,
I've a user interface made by QML, and now I'm starting to develop the backend engine of the application (the C++ core).
I've see on doc guide, that there are a lot of different ways to establish comunication from these two part of the application: what is the best, and simpliest?
Thanks

None is best, most are simple once you get the idea ;)

I usually attach QObject-derivatives as global context properties to QML for stuff that I need everywhere (for example, app settings). Then I also use custom QQuickItem subclasses and register them to do some more hardcore integration with C++ (and save some memory and CPU power) in some cases.

The least useful (in my specific use case!) is the "static" context property: I only use it to manage relative paths (I have a PWD property that holds the root dir).
