Hello, flexcoders.
We tried to create an itemRenderer for that headers based on Label and TextField components applying rotation property. In this case, we got ugly offset effect and don't see any text at all. It just lifts up away. Using Rotate object we get better result - text showed in that headers has some vertical and horizontal offset. We also tried to use originX(Y) properties of Rotate object but it is hard to understand how they influence the rotation in this case. -- A vivid and creative mind characterizes you.
