Question

最近我开始学习pygtk。作为练习，我计划建立一个小型的阅读器。目前我有以下（工作）代码：

#!/usr/bin/env python

import pygtk
pygtk.require('2.0')
import gtk

class FeedbarWindow():
    prop_file = 'feedbar.prop' #Properties File
    menu_bar_ui =   """ 
                    <ui>
                        <menubar name="MenuBar">

                                <menuitem action="RefreshAll"/>
                                <menuitem action="MarkAllAsRead"/>
                            </menu>

    feedbar.main()

一切正常，但菜单中的图片没有显示出来。你有任何提示吗？这是一个程序员的失明之类的东西，我在路上失去了一些东西吗？

图标显示在菜单中，确保您启用了菜单图标。来自终端：gconftool-2 --type bool --set /desktop/gnome/interface/menus_have_icons True

PyGTk图片未显示在菜单中
