摘要
数字电视(DTV)系统需要为用户提供良好的图形用户交互界面。在DTV平台中,如果采用QT/Embedded作为底层图形库,则需要帧缓冲(FrameBuffer)设备处理相关的底层命令。针对DTV目标平台不支持FrameBuffer的问题,对Qt/Embedded的底层图像抽象层进行了深入地分析,提出了Qt/Embedded的改造方案,将Qt/Embedded图形库成功地移植到目标平台上,对嵌入式图形库的移植有很好的借鉴价值。
DTV (digital television) system should provide a well-defined GUI to users. When adopt the QT/Embedded as the basic graphic library in a DTV platform, a framebuffer device is necessary to process the interrelated command of bottom. The basic graphic abstract layer of QT/Embedded is analyzed, a modification scheme to adapt it to the non-framebuffer DTV platform is proposed, and transplants it into the target platform successfully.
