圖形用戶(hù)界面是嵌入式系統(tǒng)中重要部分，是用戶(hù)與系統(tǒng)進(jìn)行交互的樞紐，如何建立一個(gè)有效的消息機(jī)制，實(shí)現(xiàn)消息從用戶(hù)到系統(tǒng)的傳遞，以及系統(tǒng)對(duì)消息的處理如何再反映
到圖形用戶(hù)界面是嵌入式系統(tǒng)開(kāi)發(fā)的重要環(huán)節(jié)。本文通過(guò)對(duì)MiniGUI 的消息機(jī)制的分析后，介紹一種簡(jiǎn)單的基于嵌入式系統(tǒng)的消息機(jī)制的實(shí)現(xiàn)方法，其相對(duì)于專(zhuān)業(yè)的GUI 中間件中的消息機(jī)制簡(jiǎn)單許多，但是也有著完善的結(jié)構(gòu)，便于系統(tǒng)整合在一起，非常適用于一些輕量級(jí)圖形用戶(hù)界面的嵌入式應(yīng)用。

Abstract: GUI(Graphics User Interface)is an important part of embedded system, it is the
hinge of the interaction between the users and the system. How to implement an effective message mechanism for the system to receive messages form the users and how to reflect on the GUI after dealing with the messages is a crucial step in embedded system developing. This paper analyses the message mechanism of MiniGUI and then give out a method to implement a message mechanism based on embedded system. This mechanism is simpler compared with some other professional GUI middleware, but it also has a integrated structure and easy to be integrated into the system，it is adapted to be used in the embedded systems which just need a simple GUI .
