file_menu = gtk.Menu()

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。
