【正文】 ssage queue initialization: considering the defects of the multimessage queue GUI system in system overhead and resource consumption, and there are usually very little interaction between the graphical user interface and realtime control tasks in a embedded system, so the GUI in this paper is a single message queue architecture ． The GUI system will initialize the message queue when beginning running to make it in a normal work state ．1）消息隊列初始化：考慮到多消息隊列GUI系統(tǒng)開銷和資源消耗的系統(tǒng)缺陷，通常有很少的互動關(guān)系的圖形用戶界面和實時控制任務(wù)，因此GUI本是一個單一的消息隊列架構(gòu)。 2) Message cycle: when the windows, controls the application created have been pletely displayed on the screen, to enter the message loop waiting for input events, and the message cycle flow as shown in figure 2）消息循環(huán)：當控制應(yīng)用程序窗口和控件創(chuàng)建已經(jīng)完全顯示在屏幕上，進入消息循環(huán)，等待輸入事件，消息循環(huán)流如圖4所示。message processing function ． D.

Desktop子模塊 Desktop is a very important part of the GUT system, which is equivalent to a bottom window ， all the main windows are covered On it, also it preserves many global桌面是非常重要的圖形用戶界面系統(tǒng)的一部分，這相當于一個底部窗口，它涵蓋了所有主要的窗口，也保留了許多全球業(yè)務(wù)在GUI中，如輸入消息的分布；增加影響的主要窗口的處理。l) Window addition: when the user creating a main window in the calling system API, in addition to setting its own character attribute value, also the related system information will be changed, for example, there is overlapping relationship between the new main window and the existing main window, which will be related to the operation of the Z order list: and the new added main window will lead to the change of the existing main window cut information ．1）窗口添加：除了設(shè)定自己的屬性值，當用戶在調(diào)用系統(tǒng)API創(chuàng)建一個主窗口時，相關(guān)系統(tǒng)的信息也將被改變，例如：新的主窗口和現(xiàn)有的主窗口之間有重疊的關(guān)系，這將關(guān)系到Z序列表的操作：新增加的主窗口將導(dǎo)致現(xiàn)有的主要窗口削減信息的變化。窗口模塊提供的功能來刪除通過系統(tǒng)調(diào)用的窗口，到桌面最終發(fā)送MEG_REMOVEMAINWIN的消息。需要顯示其他窗口被遮住的部分，然后更新目標窗口的移動對其他窗口的影響以及系統(tǒng)變量 。For the main window, it actually is to send a MSG_SHOWMAINWIN message to the desktop ．對于主窗口，它實際上是發(fā)送MSG_SHOWMAINWIN消息到桌面。function to plete this function, and send MSG_SHOWMAINWIN message to the desktoE. Initialization on It is a basic GUI system module ， and the beginning of each GUI operation will carry out set and initialization operations for the entire GUI environment parameters through the API function of this module ．這是一個基本的GUI系統(tǒng)模塊，每個GUI操作的開始均是通過這個模塊的API函數(shù)開展整個GUI環(huán)境參數(shù)的設(shè)置和初始化操作。清除功能的GUI終止是負責在終止所有相關(guān)的清理工作完成of the 。用戶在使用它之前必須先設(shè)置定時器，它由在TJMER模塊表示數(shù)據(jù)結(jié)構(gòu)定時器，定時器限值涉及到記錄定時器時比它更大值，它將發(fā)送一個MSGTIMER消息給所屬窗口的計時器。1 ． ABLE 1 ． WINDOWS EVENT RESPONSE SPEED 表Ⅰ.
