[Tix] HList

Salut,

Le code ci-dessous crée un arbre, nais je bute sur la documentation de HList... Bien que j'utilise les fonctions add() et add_child() de hlist, je ne sais pas comment pointer l'objet qui est créé... Donc je n'arrive pas à le détruire, lui mettre des binds, etc... En fait, la ligne retval = tree.hlist.add(...) retourne une chaine représentant le nom de l'objet, mais pas l'objet... Quelqu'un saurait comment accéder à l'objet? Ou un lien vers une "vraie" doc de Tix, je n'ai que ce qui est accessible sous pydoc. Merci d'avance.

Salut,

Je commence à entrevoir la philosophie des arbres sous Tix. Il m'a fallu plusieurs jours pour y arriver. Je constate avec amertume que la connaissance ne se partage pas si facilement que ça... Je poste bien sûr le code, car j'ai l'esprit communautaire, moi. Le double click sur un objet provoque l'apparition d'une fenêtre.

de la doc sur tix : http://tix.sourceforge.net/
la partie turotials est plutot bien faite

Je ne comprend pas le prbleme, ton code a l'aire de bine fonctionner
