毕业论文--多文本编辑器设计与实现.doc

PAGE I 摘 要 在深入研究当前各种文本编辑软件优劣的前提上，分析软件开发中程序员的实际需求，发现他们有时候并不需要打开系统庞大、启动较慢的集成开发环境来阅读改写代码，只需要通过小型的文本编辑器即可。然而大多数小型文本编辑器并不能高亮显示代码中的关键字，或者软件本身闭源，不能根据需要改变高亮显示关键字列表，或者软件只有windows版或Linux版平台移植性较差，这并不能满足经常需要在各个软件系统平台之间交叉开发的程序员的需求，甚至影响了他们的工作效率。本系统运用了平台移植性较好的Qt语言来开发，不同平台之间只需要重新编译即可，且代码易读可重用性良好，程序员只需要修改代码中关键字列表或根据需要自定义自己的高亮显示关键字列表即可，这一软件为程序员阅读改写代码提供了便利。 关键词 自定义；多文本编辑器；Qt；高亮显示  The Design and Implementation of Multiple Document Editor Abstract In the further study of the current various text editing software quality on the premise of the analysis of the actual demand of software development programmers, find that they sometimes dont need to open the large system, start the slower integrated development environment to read rewrite code, you just need to through the small text editor. But most small text editor is not highlighted keywords in your code, or closed source software itself, not according to the need to change the highlighted keywords list, or software version only Windows or Linux version of the moving platform plant sex is bad, it doesnt meet often need to cross between different software system platform development demand for programmers, and even affect their work efficiency. This system USES the platform portability better Qt to develop language, you just need to recompile, between the platform and code easy to read good reusability, programmers only need to modify the code in the keywords list or according to the need to customize your highlighted keywords list, this software provides convenience for programmers to read rewriting code. Key words: multiple document editor; plugins; custom highlight 目　　录 摘要 PAGEREF _Toc389143518 \h I Abstract PAGEREF _Toc389143519 \h II 1．绪论 1 1．1现实背景和理论背景 1 1．2研究目的和意义 1 1．2．1目的 1 1．2．2意义 1 2．软件需求分析 2 3．开发模型的确定 3 3．1软件工程及其开发模型概述 3 3．1．1软件工程 3 3．1．2开发模型概述 3 3．2确定增量模型 6 4．QT简介 7 4．1 QT支持的平台 7 4．2 QT的不同发行版本 7 5．多文本编辑器的设计和实现 8 5．1信号/槽机制 8 5．1．1信号/槽机制概述 8 5．1．2一个小
