Question

我在Glade 3.6.7中创建了一个简单的窗口GUI，我试图将其导入Python。每次我尝试这样做时都会出现以下错误：

(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

我的Python代码：

#!/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()

foo.glade文件：

foo.glade和上面的python脚本在同一目录中，我尝试使用完全限定的路径，但仍然得到相同的错误（我确定路径是正确的！）。

有什么想法吗？

Answer 1

您已经创建了一个GtkBuilder文件，而不是Glade文件。

您可以按照以下方式使用GtkBuilder：

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

修改：

当您在林间开始一个新项目时，它会询问您是否要创建一个新的，更灵活的林间文件或GtkBuilder文件。使用以下代码尝试构建器文件：

#!/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()

<强> EDIT2：

请注意，我在GtkBuilder文件中看不到任何处理程序

Answer 2

我有同样的问题，皮特提到过。在mg给出的答案之后，我所做的是以liblgade格式而不是GTKBuilder保存.glade文件。在“另存为...”对话框的底部，您可以选择“文件格式”，单击“liblglade”并瞧!!!!

Python Glade无法创建GladeXML对象
