Sorry I missed the specific approach. The docs say for NSGraphicsContext -isFlipped: "The state is determined by sending isFlipped to the receiver’s view that has focus. If no view has focus, returns NO unless the receiver is instantiated usinggraphicsContextWithGraphicsPort:flipped: specifying YES as the flipped parameter." HTH, Keary Suska Esoteritech, Inc.
