Well... I don't know if you can actually do that.

There's no need to resolve anything, just build the Widgets import using 
different code depending on the platform you're building for. Code could 
be shared or not as appropriate.

I suppose you'd also need some kind of test suite that validated the 
source-compatible promise of this Widgets import.


Nothing I've heard about QML Components work has led me to believe a 
source-compatible, cross-platform API is what is being created.

eg.
http://labs.qt.nokia.com/2011/03/10/qml-components-for-desktop/
"The API is mostly aligned with our ongoing mobile SDK effort, but I 
also had to create some uniquely desktop-related widgets such as 
ScrollBar, ScrollArea and TabFrame."


Because I'm lazy, I won't be investing any effort into learning a QML 
API that only works on 1 platform.
