摘　　要：嵌入式GUI(Graphical User Interface)为嵌入式系统提供了一种应用于特殊场合的人机交互接口(Man-Machine Inter-face)。由于嵌入式系统本身的硬件资源有限,要求嵌入式GUI具有高度可移植性和可裁剪性,以适应不同的硬件条件和使用需求。首先介绍嵌入式Linux GUI目前的发展状况及各自的特点,然后针对目前主流的嵌入式GUI系统——Qt/Embedded,阐述其图形引擎的实现。最后,结合三星公司S3C2410的开发板,实现了一种嵌入式GUI系统在具体平台上的应用。Embedded GUI provides a man-machine interface for embedded systems that are applied to special occasions.The limitation of hardware resources of the embedded system demands its GUI to be highly portable and tailorable so as to adapt to various hardware platforms and practicalities.The article starts off by introducing the present development of embedded Linux GUIs and their respective characteristics.Next aiming at Qt/Embedded,a mainframe embedded GUI system,the article expounds how to realise its graphic engine.What＇s more,by integrating Samsung S3C2410 development board,the authors have achieved the application on a specific platform for an embedded GUI system.
