研究了 Qtopia 体系结构和在 Linux系统下建立 Qtopia交叉开发编译环境，在此基础上设计电子菜单的开发框架以及应用程序，开发基于 Qtopia图形化的人机接口界面（ GUI ），并用中文显示，移植到ARM9开发板中，界面友好，运行正常，有效地改善了人机接口操作效率，提高了产品的质量。%The archtitecture of Qtopia and the establishment of cross-compiler development environment under Linux system are introduced in this paper. Then,the development framework and application program of electronic menu system are designed. The Graphical User Interfaces ( GUI) based on Qtopia and displayed in Chinese,is de-veloped and transplanted to ARM9 development board. The running result shows a friendly interface and smooth op-eration. Qtopia is employed as support environment of human-machine interface in embeded constant system appli-cation program,which greatly improve the operation efficiency of GUI and upgrade the product quality.
