嵌入式中文拼音输入法的设计
摘要
计算机技术发展到今天,嵌入式系统在各行各业的应用越来越广泛,可以说嵌入式计算机的应用在数量上远远超过了各种通用计算机。嵌入式系统是继IT网络技术之后,又一个新的技术发展方向。由于嵌入式具有体积小、性能强、功耗低、可靠性高以及面向行业应用的突出特征,目前已经广泛的应用于军事国防、消费电子、网络通讯、工业控制等各个领域。随着计算机技术和通信技术的发展,嵌入式系统的研究与开发也有着越来越重要的实际意义。
嵌入式系统的开发以成为新的行业热点。将嵌入式应用至工业控制类产品中,并开发出优秀的人机交互界面,是嵌入式发展的趋势,拥有广阔的市场前景。近年来的市场需求显示越来越多的嵌入式系统包括PDA机顶盒/DVD/VCD/播放机WAP手机均要求提供一个方便简洁的可视化操作界面,而这些都要求有一个高性能稳定可靠的图形用户界面来提供支持。国内用户对支持中文输入法的轻量级GUI的需求也日益迫切。
本文首先概述了嵌入式系统概念、组成及用户界面的发展情况,接着指出嵌入式系统下的图形用户界面具有轻型、占用资源少、高性能、高可靠性、可配置等特点。其次详细阐述了技术上涉及到的问题:选择合适的图形用户界面开发软件平台,并且进行环境搭建;利用QT中的库函数设计开发了一个带有软键盘的中文输入法。

Embedded Chinese Input Method
ABSTRACT
With the rapid development puter technology, embedded system is more and more widely used. By now, puter system is much more puter in quantity. Embedded system is a new direction of technology development after work technology. With the prominent advantages of small volume, powerful performance, low power dissipation, high reliability and special purpose, embedded system is widely used in fields of national defense, consume electronic, munication, industry control and so on. With the development puter munication technology, research and development of embedded system are more and more useful.
The development of embedded system has e a new hotspot in the business. Applying embedded system in industrial production of control class and developing outstanding puter interaction are the development trends of flush type and these will have wide market prospect, In recent years, market demand shows that more and more embedded system, such as PDA STB, DVD/VCD players, WAP mobile phone and so on, require to be supported by a convenient and visual controlling interface or a functional Web explore. And all of these need to be supported by a stable and credible GUI with high performance.
First the thesis outlines the history
