毕业论文_基于QT的嵌入式电子相册(5)

越来越多的嵌入式终端需要一个图形化的人机接口界面(GUI),良好的人机交互界面是嵌入式系统设计的一个关键技术,尤其是在嵌入式手持设备中,对嵌入式终端的实用性、美观性和视听娱乐性提出了更高的要求。而记事本和电子相册以其实用性和良好的观赏性逐渐成为嵌入式设备中不可或缺的组成部分。开发基于嵌入式终端的界面美观、功能丰富、交互性好的记事本和电子相册,具有一定的实用意义和价值。本文的目标是设计和实现嵌入式

Embedded terminal application program development based on QT

——Development of notepad and electronic album

Abstract

More and more embbeded Embedded Terminal need graphics user interface(GUI). A good Human-Computer Interaction interface is the key technology of embedded system design. Higher demands of the practicality, aesthetics and audio-visual entertainment of embedded terminal are needed, especially in embbeded system handheld device. Notepad and electronic photo album are becoming an integral part of embedded device for their pracicality and good viewing. It has some practical significance and value to develop a notepad and an album with beautiful interface, rich functions and good interaction based on embedded terminal.

The aim of this paper is to design and implement a notepad and an album in the embeded terminal environment. This paper presented the advantage of Linux and the building of QT developing environment, focused on the programming mechanism of developing software with Qt. It analysed the needs of the design, designed the specific interface and overall structure of notepad and album in the embeded terminal environment according to features of embedded application.This project designed and implemented the relevant functions of norepad(such as new file,open file ,edit file and delete file) as well as the relevant functions of album(such as enlarge 、minify、 rotate and move the picture) based on the algorithms of notepad and album. Finally, brief disscusion about the further reaserch of this paper was presented.
