Le bouton en question appelle la fonction OnDelete.
De plus, pour cette fonction, j'ai l'impression de m'etre un peu cassé la tete pour rien:?
Je pense, qu'il doit y avoir beaucoup plus simple...


Donc, ben si vous avez une petite idée...
Merci:D

T'as g_strdup pour dupliquer une chaîne plutôt que de tout faire à la main. Mais je ne pense pas que tu aies besoin de la dupliquer, tu dois pouvoir passer sSaisie directement à gtk_entry_set_text

Merci, je connaissais g_strdup_printf, mais pour g_strdup, je ne savais pas à quoi elle servait.

Voici donc ma nouvelle fonction:

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

void OnDelete (GtkButton * button, gpointer data) { gchar *sNewSaisie = NULL;   /* Recuperation du texte du GtkEntry */ if (strcmp ("", gtk_entry_get_text (GTK_ENTRY (((MainWindow *) data)->pEntry))) != 0) { sNewSaisie = g_strdup (gtk_entry_get_text (GTK_ENTRY (((MainWindow *) data)->pEntry)));   sNewSaisie[strlen (sNewSaisie) - sizeof (gchar)] = '\0'; gtk_entry_set_text (GTK_ENTRY (((MainWindow *) data)->pEntry), sNewSaisie); g_free (sNewSaisie); } }

---

ça marche maintenant:ccool:

Mais peut être qu'il y a plus simple:?

Pas besoin de rajouter le \0 à la main, g_strdup le fait pour toi.Et encore une fois, ça ne sert pas à grand chose de dupliquer la chaîne pour la passer à gtk_entry_set_text. Sinon dans une autre de tes fonctions, tu leakes la valeur de retour de g_strdup_printf

Citation:

---

Pas besoin de rajouter le \0 à la main, g_strdup le fait pour toi.

---

Ben non, le but est de placer la fin de la chaine, à la place du caractère à supprimer.
Le petit problème, c'est que si on veut supprimer un caractère en milieu de chaine, on supprime tout ce qu'il y a après avec:?
Donc, placer un '\0', n'est peut-être pas la meilleure solution.

Citation:

---

Sinon dans une autre de tes fonctions, tu leakes la valeur de retour de g_strdup_printf

---

Par contre, là je ne comprends pas trop ce que tu veux dire...

AH oui, j'avais oublié que tu virais les \n, pardon.

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

void OnButton (GtkButton * button, gpointer data) { const gchar *sEntry = NULL;   /* Recuperation du calcul en cours dans la chaine sEntry */ sEntry = gtk_entry_get_text (GTK_ENTRY (((MainWindow *) data)->pEntry));   /* Cocatenation du de sEntry, avec le label du bouton */ sEntry = g_strdup_printf ("%s%s", sEntry, gtk_button_get_label (button));   /* Mise a jour du GtkEntry */ gtk_entry_set_text (GTK_ENTRY (((MainWindow *) data)->pEntry), sEntry); }

---

La mémoire allouée pour sEntry (qui ne devrait aps être const char * vu que t lui assignes la valeur de retour de g_strdup_printf) n'est jamais libérée (mémoire allouée par g_strdup_printf)

alors ça donnerait plutôt ça?

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

void OnButton (GtkButton * button, gpointer data) { gchar *sEntry = NULL;   /* Recuperation du calcul en cours dans la chaine sEntry */ sEntry = (gchar *) gtk_entry_get_text (GTK_ENTRY (((MainWindow *) data)->pEntry));   /* Cocatenation du de sEntry, avec le label du bouton */ sEntry = g_strdup_printf ("%s%s", sEntry, gtk_button_get_label (button));   /* Mise a jour du GtkEntry */ gtk_entry_set_text (GTK_ENTRY (((MainWindow *) data)->pEntry), sEntry);   g_free (sEntry);     }

---

Pourtant, il me semblait que comme sEntry pointe vers l'endroit où est stockée le chaine affichée dans le GtkEntry, il ne fallait pas la libérer:?

Comme le dit la documentation:

Citation:

---

Returns :
a pointer to the contents of the widget as a string. This string points to internally allocated storage in the widget and must not be freed, modified or stored.

---

Le mieux serait dans ton cas de ne pas caster le retour de gtk_entry_get_text mais d'utiliser un pointeur sur gchar supplémentaire dans lequel tu copies la chaîne contenue dans sEntry puis ce que tu veux en plus comme tu l'as fait. Par contre ce nouveau pointeur devrait être libéré lorsque tu n'en aura plus besoin !

Code:

---

1 2 3 4 5 6

{ gchar *sEntry = NULL;   /* Recuperation du calcul en cours dans la chaine sEntry */ sEntry = (gchar *) gtk_entry_get_text (GTK_ENTRY (((MainWindow *) data)->pEntry));

---

A cet endroit, gtk_entry_get_text pointe sur de la mémoire appartenant au GtkEntry, donc il ne faut effectivement pas la libérer.

Code:

---

1 2 3

/* Cocatenation du de sEntry, avec le label du bouton */ sEntry = g_strdup_printf ("%s%s", sEntry, gtk_button_get_label (button));

---

Là tu as écrasé la valeur précédente de sEntry avec une nouvelle valeur qui a été allouée, il faut donc libérer ce nouveau contenu.

Citation:

---

Comme le dit la documentation:

Returns :
a pointer to the contents of the widget as a string. This string points to internally allocated storage in the widget and must not be freed, modified or stored.

---

Je me disais bien qu'il y avait un truc dans le genre, faudrait que je regarde plus souvent la doc...;)

Donc, voilà ce que ça me donne:

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

void OnButton (GtkButton * button, gpointer data) { const gchar *sEntry = NULL; gchar *sEntryUpdated = NULL;   /* Recuperation du calcul en cours dans la chaine sEntry */ sEntry = gtk_entry_get_text (GTK_ENTRY (((MainWindow *) data)->pEntry));   /* Cocatenation du de sEntry, avec le label du bouton */ sEntryUpdated = g_strdup_printf ("%s%s", sEntry, gtk_button_get_label (button));   /* Mise a jour du GtkEntry */ gtk_entry_set_text (GTK_ENTRY (((MainWindow *) data)->pEntry), sEntryUpdated);   /* Liberation de la memoire allouée */ g_free (sEntryUpdated); }

---

D'ailleurs, au passsage, je voulais rajouter une fenetre qui permettrai de visualiser le graphe d'une fonction.
Il faudrait donc, que j'utilise une DrawingArea, ou GtkSdl, mais pour ce dernier, il me semble qu'il n'est pas vraiment au point...
Cependant, il existe des tutos sur sdl, mais pas pour les DrawingArea:aie:

Donc, si vous pouvez me conseiller sur ce point...:D
Merci

Tu as les GtkCurve.

Oui, effectivement, ça à l'air interessant, si t'as des liens pour des tutos, parce que moi et l'anglais...:aie:
