Nit: I'd put the !targetArea.isValid() check first, since it's inline.

This variable should be const.

endPositionRange would be a better name I think.
Actually, thinking about it, I personally prefer "final" to "end" in this context, but maybe "end" is an existing QtQuick convention. Regardless, NABD.

Good point

It is, but Pos was choosed to be similar to the QQuick API :-) setPosRange() *hint*

Yeah that is used all over in the API (and in our code)
