Python Glade konnte kein GladeXML-Objekt erstellen

Question

Ich habe in Glade 3.6.7 ein einfaches Fenster-GUI erstellt und versuche es in Python zu importieren. Jedes Mal, wenn ich versuche ich, dies zu tun, erhalten die folgende Fehlermeldung:

(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 

Mein 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() 

Und die foo.glade Datei:

foo.glade und die über Python-Skript sind im selben Verzeichnis, und ich habe versucht, einen voll qualifizierten Pfad zu verwenden, aber immer noch den gleichen Fehler (ich bin mir sicher, dass der Pfad korrekt ist!).

Irgendwelche Ideen?

Cheers,

Pete

Answer 1

Sie haben eine GtkBuilder Datei statt Glade-Datei erstellt.

können Sie GtkBuilder wie folgt verwendet werden:

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

EDIT:

Wenn Sie ein neues Projekt in Lichtung starten Sie gefragt, ob Sie eine Glade-Datei oder eine GtkBuilder Datei erstellen möchten, die ist neu und flexibler. Versuchen Sie, die Builder-Datei mit dem folgenden Code:

#!/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:

Beachten Sie, dass ich keine Handler in Ihrer GtkBuilder Datei

Answer 2

sehen hatte ich das gleiche Problem Pete erwähnt. Nach der Antwort, die mg gegeben hat, habe ich die .glade-Datei im liblgade-Format anstelle von GTKBuilder gespeichert. Im Dialogfeld "Speichern unter ..." haben Sie unten die Option "Dateiformat", klicken Sie auf "liblglade" und voila !!!!
