基于Qtopia的数码相框软件开发

摘要

基于Qtopia的消费电子类产品应用程序的开发正日益成为嵌入式GUI开发的主流.介绍了数码相框产品开发使用的软硬件平台,描述了Linux操作系统中构建Qtopia开发环境及移植到基于S3C2440的硬件平台的过程,重点介绍了使用Qtopia程序库开发数码相框应用的关键技术环节.结果表明:Qtopia可为基于嵌入式Linux的移动设备快速开发出高品质的图形系统.%The application development of consumer electronics products based on Qtopia increasingly become the mainstream of embedded GUI development. Hardware platform and software platform used in digital photo frame is introduced. Then, the steps of building Qtopia development environment on Linux and the process of transplanting to the hardware platform based on S3C2440 are described. Finally, the key technique about developing digital photo frame application by using Qtopia Development Kit is elaborated. The results show that Qtopia can support rapid development of high quality graphics system of embedded mobile equipment using Linux.
