un premier rapport wonderland
by Remi Sussan 15 Aug '04

15 Aug '04

En exemple d'un premier "rapport" sur les problemes wonderland, je renvoie ici mon courrier de 2003 à la squeak-dev. Non pas pour recevoir une réponse (le probleme est assez tordu, j'en conviens, mais fondamental, car il remet en question le systeme de hierarchie d'objets de Wonderland et risque, si je ne me suis pas trompé et s'il n'y a pas de solution, d'invalider toute création un sophistiquée avec ce systeme), mais juste en contribution au groupe ! De plus, c'est un exemple d'utilisation un peu complexe de Wonderland, en dehors de la fenêtre script, cela peut donc faire office de petit tutoriel sur le sujet (mais un tutoriel qui echoue à la fin!)
