将file_item做为子菜单加入到file_menu
file_item.set_submenu(file_menu)
在menubar中加入菜单项
menu_bar.append(child)
比如：
menu_bar.append(file_item)
在menubar中右调整，比如help菜单等，我们使用下面的方法：
menu_item.set_right_justified(right_justified)
=========================
1.使用gtk.Menu()创建新的menu
2.gtk.MenuItem() 创建子菜单项，然后使用append()
3. set_submenu() 将子菜单项加入menu中
4.使用gtk.MenuBar()创建menubar
5.append()加入菜单项
6.设置事件
widget.connect_object("event", handler, menu)

TreeStore提供分等级，分层次的数据存储，而ListStore提供表格的数据存储,TreeModelSort提供一个排序的模型，TreeModelFilter提供数据子集。通常有以下几个步骤：
1.创建一个tree model对象，通过ListStore或TreeStore
2.TreeView widget 创建并与tree model关联
3.一个或多个TreeViewColumns被创建并插入到TreeView，每个代表一列
4.对于每个TreeViewColumn，CellRenderers被创建并加入TreeViewColumn
5.设置每个CellRenderer的属性
6.TreeView被插入并显示在Window或ScrolledWindow中
7.响应用户的操作

此外,py在WIN下需要配置环境变量:
假设python的安装路径为c:\python2.6，则修改我的电脑->属性->高级->环境变量->系统变量中的PATH为:
(为了在命令行模式下运行
Python命令，需要将python.exe所在的目录附加到PATH这个环境变量中。)
PATH=PATH;c:\python26
上述环境变量设置成功之后，就可以在命令行直接使用python命令。或执行"python *.py"运行python脚本了。
