"There is no 'String' property in the 'figure' class."

Bonjour,

Je travaille actuellement sous MATLAB (GUIDE toolbox).

Je débute sous cet environnement.

J'ai réussi à créer des petits programmes qui m'ont permis de prendre en main le logiciel (par exemple récupérer le texte d'une "editbox", puis en cliquant sur un "pushbutton", afficher ce texte dans une autre editbox sans problème).

Cependant, je me suis lancé dans quelque chose d'un peu plus compliqué (pas mal d'editbox et de pushbuttons) et en voulant tester une première editbox, et en voulant juste afficher son contenu dans une editbox dite de "sortie", j'obtiens un message d'erreur.

Voici le code du pushbutton:

Code:

---

1 2 3 4 5 6 7

% --- Executes on button press in ex1. function ex1_Callback(hObject, eventdata, handles) txt1 = get(handles.RG1Y02,'String'); set(handles.sortie,'String',txt1); % hObject handle to ex1 (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA)

---

Et voici le message d'erreur :

??? Error using ==> set
There is no 'String' property in the 'figure' class.

ça fait quelques heures que je travaille sur ce problème mais je n'arrive pas à le solutionner. Si quelqu'un pouvait m'aiguiller je lui serait très reconnaissant !

Merci d'avance.

Bonsoir,

De quelle façon as-tu défini handles.sortie ? À l'aide du Tag dans GUIDE ? N'a tu pas effectué un changement dessus ?
L'erreur semble dire qu'elle contient le handle d'une figure, et non d'un objet Edit Text.

Bonsoir Winjerome,

J'ai défini le

Code:

---

sortie

---

dans le tag de GUIDE pour l'objet editbox qui doit afficher ma sortie.

J'ai écrit

Code:

---

handles.sortie

---

directement dans le code en appelant le CallBack du PushButton.

Je ne suis vraiment pas à l'aise avec la notion de "handles" (je n'ai pas encore eu le temps de me lancer dans le tuto, et normalement pour ce que j'ai à faire, j'aimerai pouvoir faire mon programme sans avoir à maitriser tous ces concepts, si possible).

C'est bien ce qu'il fallait faire :)
Mais je soupçonne qu'il y ait quelque chose dans ton code qui change cela.

:nono: C'est pas bien de dire ce genre chose.

Oui je sais, je ne devrai pas dire ce genre de choses, mais je suis assez limité par le temps en ce moment....mais bon s'il faut vraiment que je le fasse je le ferai...!

Par contre, pour ce qui est de l'erreur, c'est vraiment très particulier.

Voici le message d'erreur complet :

Je ne sais vraiment pas à quoi j'ai pu toucher sans faire expret, étant donné que mes petits programmes tout simples marchaient, et là je souhaite faire la même chose mais sur un .fig où il y a plus d'éléments.... bizarre

Bin à la valeur de handles.sortie :P

Par hazard, est-ce que c'est bien le Tag de l'objet Edit Text que tu as changé sur GUIDE et non celui de la figure ?

Oui le Tag de l'objet Edit Text est bien "sortie", et celui de la figure est encore "figure1".

C'est pour ça que je ne comprends pas l'erreur

There is no 'String' property in the 'figure' class.

ce qui sous entend que je dois définir la propriété 'string' sur la figure....je suis un peu perdu là. 8O

Donc il reste le changement dans le code.
Tu as la possibilité de le montrer ?

Oui bien sur. Il est un peu long (car beaucoup de Edit Box) :

Peut être est-ce dû au fait que le code qui représente les editbox se trouve sous le code du pushbutton ?

Ligne 56

Code:

---

handles.sortie = hObject;

je l'avais bien dit non ?

Bien vu.

Vu que je ne suis pas encore familier avec les notions de handles et hObject, je ne sais pas si je dois tout simplement supprimer cette ligne ou la modifier. Pourrais-tu m'éclairer là dessus?

Par contre, je n'ai aucune idée de comment cette ligne a pu se créer...

Cette ligne est générée automatiquement à la création du .m par GUIDE.
Elle sert à faire ressortir le handle de la figure (par la fonction OutputFcn) en appelant ton interface comme ceci :

Code:

---

handleFigure = v1

---

Pour plus de détails : comprendre la fonctionnalité de OutputFcn et OpeningFcn.

Merci de ton aide. J'ai passé la ligne en commentaire et tout est rentré en ordre.

Le but final de mon programme est d'essayer d'intégrer la toolbox "cftool" dans mon code (en vue de "fitter" un nuage de points à partir de mesures expérimentales, donc il va effectivement falloir que je me familiarise avec toutes ces notions de handle etc. si je veux essayer de comprendre ce que je fais sans recopier bêtement du code et passer mon temps à débugger :P

Merci en tout cas, je passe le topic en "résolu".
