Yes, it's either (. aLayer addChild aNode) or (.addChild aLayer aNode). The latter macroexpands to the former: user=> (macroexpand-1 '(.addChild aLayer aNode)) (. aLayer addChild aNode) People here seem mostly to prefer the (.method object args) form. -- Michael Wood <esiot...@gmail.com> -- You received this message because you are subscribed to the Google Groups "Clojure" group.
