gtk_list_store_append fonctionne mal

**TONIAPEL** · 03/09/2007, 04h29

Bonjour

Je débute en GTK+, je viens de commencer un programme de gestion de compte banquaire, histoire d'apprendre à utiliser cette librairie.

J'utilise une GtkListStore comme modèle dans une GtkTreeView.
Quand j'ajoute une ligne à la liste, cette ligne est remplie de cellules vides, quelques soient les données à y placer.

Je gère sans doute mal les appels aux fonctions gtk_list_store_append et gtk_list_store_set.

Néanmoins je ne vois pas où est l'erreur, j'ai pourtant procédé de la même manière que dans les tutos...

J'ai également comparé mon code avec celui d'autres programmes utilisant les listes, sans résultat.

Pourriez-vous m'indiquer où est mon erreur ?
La fonction d'insertion de ligne est add_click. Veuillez m'excuser de poster un si long code, mais je ne situe pas précisément d'où vient l'erreur.

Code :

Veuillez m'excuser de poster un si long code, mais je ne situe pas précisément d'où vient l'erreur.

Justement, le fait de virer un maximum de code de ton programme et de localiser au maximum à quel endroit le problème se produit te permettrait peut être de comprendre tout seul ce qui ne va pas...

Rebonjour,

Excusez-moi pour le long code, j'ai réussi à sucrer pas mal de code, maintenant il est tout petit

Mais l'erreur est toujours présente, et franchement je ne vois pas ce que j'ai fait de mal

Ok, j'ai trouvé...

Il fallait ajouter l'attribut "text" ou "active" suivi du numéro de la colonne correspondante à l'appel de la fonction gtk_tree_view_column_new_with_attributes, désolé

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

gtk_tree_view_column_new_with_attributes(title_col[i],
                gtk_cell_renderer_text_new(), "text", i, NULL);

gtk_list_store_append fonctionne mal
