【摘要】 概要介绍了中间件的应用现状以及中间件、菜单中间件的概念。在系统设计的描述中,按照菜单的组成分别介绍了菜单条类、菜单按钮类以及菜单项类的接口设计思路并给出面向用户的接口函数。重点介绍了设计实现中的关键技术:链表的创建及消息响应的传递。以设计中的源码作示例,详细描述了双向循环链表在菜单创建过程中的建立过程,以及菜单消息响应的创建及消息间的传递过程。更多还原

【Abstract】 The term of middleware and menu middleware are introduced summarily first. During the describing system designing, the designing thought of the interface of the cluster of menu buttons, bars, and items are introduced. Meanwhile, interface functions are given to the users. After that, the key technology of designing realization is introduced particularly: the founding of link list and the delivering of message-responding. Based on an example of the code in programming, the process to set up doubly linked list is described in details as well as the transmitting process between messages.更多还原
