| 摘 要： | 嵌入式系统的广泛应用促进了嵌入式Linux图形用户界面(GUI)的发展,Qt/Embedded是一个易扩展且被广泛使用的嵌入式图形系统。为满足特定的界面需求,需对现有图形系统的控件进行扩展研究。分析了嵌入式图形系统Qt/Em-bedded的实现技术,然后对控件扩展方法进行了研究,在此基础上实现了一个具有特殊外观且透明度可调的容器控件,最后阐述了将扩展控件并入Qt/Embedded控件集的方法。提出的控件扩展方法,可以快速地定制出个性化控件,丰富图形界面;扩展控件合并到控件集不仅完善了原有控件功能,还提高了开发效率。

| Abstract: | With the wide use of embedded systems,it accelerates the development of GUI in embedded Linux.Qt/Embedded is an embedded graphic system which is easily extended and widely used.In order to satisfy the requirements of special interface,it is needful to research how to extend widgets on existing graphic systems.This paper analyzes the technologies of implementation of embedded graphics system Qt/Embedded in detail,and researches into the methods of extended widgets,and then implements a container widget which has a special appearance and its transparence is adjustable.Lastly,the paper expounds the method of merging extended widgets into the sets of widget in Qt/Embedded.The extended widgets can make graphic interface colorful and ameliorate the function of original widgets.The method of extending widgets which is putted forward in the paper can help us to customize special widgets quickly and improve the efficiency of programming. |
