[Development] HEADS UP: Changes in QStyle subclasses

[BogDan]

Hi,

Are you planning to use QStyle also to draw QML Components? 
Or we still need to create two separate implementations for the same platform?
If we still need to create two, then IMHO you should make private everything
related to QStyle.

BogDan.
