Research And Application Of Cross-platform Human-computer Interface Based On Qt

With the rapid development of computer technology, various new platform and new technology emerged continuously, which made computer software manufacturer and the designers face some problems such as how to adapt to various platform, the problem that operating system coexists.The development of human-computer interface occupies more and more important position in the development of modern software and it connects the computer technology with people, which makes the computer technology reach the humanity to the greatest degree. Meanwhile, the development of human-computer interface closely connects with the systematic platform in a set of software, Its workload takes up the most part in the whole development work. The program with the same function can run in different systematic platform, and maintain the same interface and functionality, thereby enhancing the flexibility and portability of the procedures; the cross-platform function of the program has been caused of more concern. Qt is GUI for high performance of cross-platform software development and can be used in Windows, Linux, MacOSX and a lot of platforms. Qt has good structure:a flexible object oriented structural, distinct document as well as visual API. It has offered a good support to develop the human-computer interface across the platform application program.This paper firstly elaborated some basic concepts and the development condition of human-computer interface. It also introduced the development of cross-platform, and pointed out the background, content and the significance of this research. Then, it introduced the design content and importance of the human-computer interface which combined with the actual requirement and the characteristic of cross-platform human-computer interface as well as analyses the design law and organization principle that this system should follow in the development course. The following was about the introduction of cross-platform lib, that was the current popular cross-platform lib and its characteristic, and the focal point was about the Qt lib. Through the design of human-computer interface and the analysis cross-platform lib, combining with the self-characteristic of the software, it suggested that cross-platform method and principle of developing human-computer interface.Finally, under the guidance of these methods and principles ,a human-computer interface cross-platform was set up using Qt lib.
