Python Glade konnte nicht GladeXML Objekt erstellen

Question

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

(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 der obige Python-Skript ist im gleichen Verzeichnis, und ich habe versucht, einen voll qualifizierten Pfad, aber immer noch die gleichen Fehler (ich bin sicher, dass der Pfad korrekt! Ist).

Irgendwelche Ideen?

Cheers,

Pete

Answer 1

Sie haben eine GtkBuilder Datei statt Glade-Datei erstellt.

Sie können GtkBuilder wie folgt verwendet werden:

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

Bearbeiten :

Wenn Sie ein neues Projekt in Lichtung starten Sie gefragt, ob Sie eine Glade-Datei oder eine GtkBuilder Datei erstellen möchten, die neue und flexibler ist. 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 sehen

Answer 2

Ich hatte das gleiche Problem Pete erwähnt. Nach der Antwort, dass mg gab, was ich tat, ist die .glade Datei in einem liblgade Format statt GTKBuilder zu speichern. Auf dem Speichern unter .. Dialogfeld am unteren Rand haben Sie die Option „Dateiformat“ klicken Sie auf „liblglade“ und voila !!!!
