【文章內(nèi)容簡介】 GUI時，初始化模塊只提供了一個整體的GUI初始化函數(shù)和清除功能，initialize the various pans of the GUI through calling a GUI initialization function ． to make the GUI work normally ． The clearance function of GUI termination is responsible for the pletion of all relevant clearance work in the termination因此界面的入口函數(shù)可以通過調(diào)用GUI初始化函數(shù)初始化GUI的各種操作，使GUI正常工作。清除功能的GUI終止是負(fù)責(zé)在終止所有相關(guān)的清理工作完成of the 。 F. Timer Timer is a very important ponent of the GUI ． When users need to timely process a certain operation it will be used, and also used in the system ． Users must first set the timer before using it, and it in TJMER module i5 expressed by the data structure TIMER, Timer limit value refers to that when the recording value of the timer greater than it ． it will send a MSGTIMER message to the window the tim定時器是一個GUI的非常重要的組成部分，當(dāng)用戶需要及時處理時將使用它，并在系統(tǒng)中使用一定的操作。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。G.

INTRODUCTIONWith the development of puter technology, embedded system has bee an important part of the puter field．The socalled embedded system, that is, a special puter system with application as center, puter technology as the basis，software and hardware can be tailored to meet the application System strict requirements for functionality, reliability, cost, size，and power consumption．Embedded puter far exceeds a variety of generalpurpose puters in the number of the applications，manufacturing industry, process control, munications，equipment, instruments，automobiles，ships，aviation, aerospace，military equipment, and consumer products are all the application field of the embedded puter．Ⅱ． USER INTERFACE BASED ON EMBEDDED LINUXA. Embedded operation systemEmbedded system has useroriented, productoriented, applicationoriented features．Different from general—purpose puters，embedded system is a special system for specific applications，generally is costsensitive， and its hardware and software must be efficiently designed, tailored to remove redundancy．A good embedded system is the minimum system to plete the target functions．In embedded system development, embedded software is
