I've created a simple window GUI in Glade 3.6.7 and I am trying to import it into Python. Every time I try to do so I get the following error:
(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
My 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()
And the foo.glade file:
<?xml version="1.0"?>

<requires lib="gtk+" version="2.16"/>

foo.glade and the above python script are in the same directory, and I have tried using a fully-qualified path but still get the same error (I am certain that the path is correct!).
Any ideas?
Cheers,
Pete
You have created a GtkBuilder file instead of Glade file.
You can use GtkBuilder as follow:
builder = gtk.Builder()
builder.add_from_string(string, len(string))
builder.connect_signals(anobject)
builder.get_object(name)
EDIT:
When you start a new project in glade it asks you if you want create a glade file or a GtkBuilder file, which is new and more flexible. Try the builder file with the following 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:
Beware that i cannot see any handler in your GtkBuilder file
I had the same problem Pete mentioned. After the answer that mg gave, what I did is to save the .glade file in a liblgade format instead of GTKBuilder. On the Save As.. dialog box, at the bottom you have the option "File Format" click on "liblglade" and voila!!!!
