Before I spend a lot of time attempting the following I would
appreciate any advice based on your experience:
I've got a drawing-like application where I'd like the user to be able
to rotate individual elements of the drawing. When the mouse is
hovering over an element I draw a manipulation image (a CALayer) and
what I'd like to do is to let the user mouse click in a little rotator
control nubby and drag to rotate.
I'm considering using a QCCompositionLayer and pulling in a nice
Quartz Composition I put together that behaves (at least in Quartz
Composer) as I'd like.
Is this a foolish or a wise direction to take?
Thanks,
Mike
