Hongqi Linux Graphical Interface Chinese Input System To Achieve

Along with the development of Linux in China,the Linux internationalization and localization become a necessarily solved problem.The Input internationalization is a most important problem of them,because the input is important to interaction between human and computer,and all application software also can be inputed text.A chinese operation system must input chinese character easily,but the past UNIX system that support internationalization and localization emphasize particularly on solving the input problem of the character interface.In order to solve the internationalization graphical text input problem,the XI18N Group put forward the XIM(X Input Method)protocol,which is used to implement graphical text input in internationlization system.In order to support internationlization,most application is developed according to XIM Protocol.For the leader of Chinese operating systemRedFlag Linux,it is our basic goal and necessary function to provide a convenient chinese graphical input system for user.In this paper,firstly I introduce the background knowledge about Linux Ii 8N.Then I introuce why must develop the input method following the XIM protocol in the Linux system and the knowledge of input method,such as input context,getting input,focus management,and so on.And then introduce the basic principle of XJM Protocol in detail,including implementation model,structure of IM,event handling model,etc.In the last I expand on the input method system structure of the RedFlag Linux X Window system,and explain the design and implement of the kernel handling program,the basic development lib and input method subsystem.The Chinese Input System introduced in this paper have been implemented in the RedFlag Linux Desktop 2.4 Version.According to the result of application, its effect is very well.
