摘要：针对当前在嵌入式图形用户界面(GUI)开发中存在的运行效率偏低、可移植性较差等问题，提出了一种基于Qt/Embedded的嵌入式GUI实现方法。详细描述了GUI开发所必需的X11虚拟编译平台搭建技术与交叉编译环境实现技术。根据具体嵌入式目标对Qt库文件进行了裁剪，实现了对汉字与图片的显示，并通过应用实例证明了该方法的有效性。

Abstract: Against some problems which exist in the current embedded graphical user interface(GUI) development, such as low efficiency in the operating, poor portability and so on, an embedded GUI development method based on Qt/Embedded was presented. Firstly, the construction technology of X11 virtual compiler platform and the implementation technology of crosscompile environment were described in details which were necessary in GUI development. Follow, the Qt library file was cut, and the picture was displayed with chinesecharacters in accordance with the specific embedded goal. In the end, the valid of the development method was proved based on Qt/Embedded through applications.
Key words: embedded; graphical user interface(GUI); signal and slot; cross compile
