Python Glade n'a pas pu créer l'objet GladeXML

Question

J'ai créé une interface graphique simple dans Glade 3.6.7 et j'essaie de l'importer en Python. Chaque fois que j'essaie de le faire, je l'erreur suivante:

(queryrelevanceevaluation.py:8804): libglade-WARNING **: Expected <glade-interface>. Got <interface>. 

(queryrelevanceevaluation.py:8804): libglade-WARNING **: did not finish in PARSER_FINISH state 
Traceback (most recent call last): 
    File "queryrelevanceevaluation.py", line 17, in <module> 
    app = QueryRelevanceEvaluationApp() 
    File "queryrelevanceevaluation.py", line 10, in __init__ 
    self.widgets = gtk.glade.XML(gladefile) 
RuntimeError: could not create GladeXML object 

Mon Python code:

#!/usr/bin/env python 

import gtk 
import gtk.glade 

class QueryRelevanceEvaluationApp: 

def __init__(self): 
    gladefile = "foo.glade" 
    self.widgets = gtk.glade.XML(gladefile) 
    dic = {"on_buttonGenerate_clicked" : self.on_buttonGenerate_clicked} 
    self.widgets.signal_autoconnect(dic) 

def on_buttonGenerate_clicked(self, widget): 
    print "You clicked the button" 

app = QueryRelevanceEvaluationApp() 
gtk.main() 

Et le fichier foo.glade:

foo.glade et la Au-dessus de script Python sont dans le même répertoire, et j'ai essayé d'utiliser un chemin qualifié complet, mais toujours la même erreur (je suis certain que le chemin est correct!).

Des idées?

Cheers,

Answer 1

Vous avez créé un fichier GtkBuilder au lieu de fichier Glade.

Vous pouvez utiliser GtkBuilder comme suit:

builder = gtk.Builder() 
builder.add_from_string(string, len(string)) 
builder.connect_signals(anobject) 
builder.get_object(name) 

EDIT:

Lorsque vous démarrez un nouveau projet dans Glade il vous demande si vous voulez créer un fichier Glade ou un fichier GtkBuilder, qui est nouveau et plus flexible. Essayez le fichier constructeur avec le code suivant:

#!/usr/bin/env python 

import gtk 

class QueryRelevanceEvaluationApp: 

    def __init__(self): 
     filename = "foo.glade" 
     builder = gtk.Builder() 
     builder.add_from_file(filename) 
     builder.connect_signals(self) 

    def on_buttonGenerate_clicked(self, widget): 
     print "You clicked the button" 

app = QueryRelevanceEvaluationApp() 
gtk.main() 

EDIT2:

Prenez garde que je ne vois aucun gestionnaire dans votre fichier GtkBuilder

Answer 2

J'ai eu le même problème Pete mentionné. Après la réponse que mg a donné, ce que j'ai fait est de sauvegarder le fichier .glade dans un format liblgade au lieu de GTKBuilder. Dans la boîte de dialogue Enregistrer sous .., en bas, vous avez l'option "Format de fichier", cliquez sur "liblglade" et voila !!!!
