Python Glade無法創建GladeXML對象

我在Glade 3.6.7中創建了一個簡單的窗口GUI，我試圖將它導入到Python中。每次我嘗試這樣做，我得到以下錯誤：Python Glade無法創建GladeXML對象

(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代碼：

#!/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()

而且foo.glade文件：

foo.glade和上面的python腳本都在同一個目錄下，並且我嘗試過使用完全限定的路徑，但仍然得到相同的錯誤（我確信路徑是正確的！）。

任何想法？

乾杯，

gladefile的外觀如何？這是絕對路徑嗎？你確定你的程序可以訪問它嗎？ – joaquin 2010-04-19 15:29:50

我試過一個絕對路徑，只是「foo.glade」，發生了同樣的事情。在訪問文件時不應該有任何其他問題，它沒有特殊的文件限制，並且自從點擊Glade中的保存按鈕後我沒有觸及它。 – Peter 2010-04-19 15:34:41

您已經創建了一個GtkBuilder文件，而不是格萊德文件。

您可以使用GtkBuilder如下：

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

編輯：

當您在林間空地開始一個新項目，它問你，如果你想創建一個林間空地文件或GtkBuilder文件，是新的和更靈活的。嘗試建設者文件用下面的代碼：

#!/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：

當心，我看不到任何處理程序在你的GtkBuilder文件

爲了使用上面的代碼，我需要創建什麼？使用Glade如何實現？（爲了完整）:) – Peter 2010-04-19 16:10:45

Peter：GtkBuilder是首選方法，使用libglade已棄用，所以，不要。 :-) – 2010-10-29 21:10:10

有用的代碼片段，但它錯過了一個重要的步驟：builder.get_object（「windowRelevanceEvaluation」）。show_all（） – 2012-06-06 00:36:49

我不得不提到皮特同樣的問題。在mg給出的答案後，我所做的就是將.glade文件保存爲liblgade格式而不是GTKBuilder。在另存爲...對話框的底部，您可以選擇「文件格式」，點擊「liblglade」，然後瞧！

嗯......它沒有文件格式選項：/ – 2015-06-18 13:06:13
