Callback d'un bouton

**dragon_clubiste** · 28/04/2009, 00h00

Salut,

C'est mon premier Sujet sur le forum et j'espère pas le dernier

Bon je suis étudiant en informatique & Multimédia et j'ai un projet sur matlab qui est de réaliser un projet avec une interface graphique permettant le choix des images et l'application de différent filtres et bruits.

Mon problème en ce moment c'est comment insérer du code sur un bouton dans GUI c'est a dire quand on clique dessus ça fait appel a une fonction ou Quitter !! enfin sa fera une action

Aider moi dans les brefs délai.

Merci

Bonjour,

Pour commencer tu devrais lire ceci:
Introduction à la programmation d'interfaces graphiques

et celà:
Développement efficace d'interfaces graphiques

Ensuite pour qu'on puisse t'aider, il faudrait que tu nous montres ce que tu as commencer à coder et où se situe précisément ton problème ou ton erreur (avec le message correspondant).

Bonne journée,
Duf

Il faut ajouter le code dans la fonction liée au Callback de ton bouton (pushbutton1_Callback)

**dragon_clubiste** · 03/05/2009, 00h18

je n'ai pû aboutir a rien
SVP faites moi un exemple un bouton qui fait un bruit sur une image

**duf42** · 03/05/2009, 09h55

Ton problème vient-il de la programmation du bouton ou du bruit sur l'image?

Quel code as-tu utilisé et quelles sont les erreurs que tu as?

Essaie par exemple d'ajouter ton code dans la fonction pushbutton1_Callback, est-ce que c'est celà que tu cherches?
