Bonjour/Bonsoir tout le monde ! J'ai posté un thread il n'y a pas très longtemps demandant des conseils pour récupérer les données de QPlainTextEdit dans une classe X, les traités et les renvoyés dans des QTextBrowser dans la classe Y. Seulement je ne vois aucun moyen de renvoyer les données dans la classe Y. J'ai essayé de nombreuses solutions mais aucune ne semble marcher. Le code qui suit est le plus récent, il compile mais ne s'exécute pas, renvoyant un signal SIGSEGV; segmentation fault. J'aimerais avoir des conseils et si possible, un ou deux snippets de code fonctionnel s.v.p . Merci d'avance !
