Dear Racket friends, I am surprised because the following code works in "lang racket", but not in R6RS: in this last case, I got a contract violation for the value associated with "alignment within the horizontal panel. Is there a way to include such a horizontal panel in a program using R6RS, please?
#!r6rs (import (rnrs base) (rnrs io simple) (only (scheme base) define-values require)) (require scheme/contract) (require scheme/class) (require scheme/gui/base) (require framework) (define top-level (new frame% (label "Animation") (width 800) (height 800))) (define hp (new horizontal-panel% (parent top-level) (alignment '(left top)))) Many thanks in advance, J.-M.
