一、设计思路

1.用一个主窗体，在主窗体上放置两个子窗体，一个是文本面板，一个是模拟键盘面板。

2.文本面板分两个子面板，一个是已有文本，一个是输入文本，在带输入文本面板上添加文件监听器，动态改变下一个带输入的key，从而改变面板上的提示输入key。

3.通过java swing绘制好模拟键盘面板，加深键盘颜色动态提示下一个正确的key，并改变当前下压键盘键的颜色，通过paintcomponent方法实现。

4.启动线程记录游戏时间，匹配正确、错误输入字数，动态显示在面板上。

5.PublicData存放所有类共享的数据：key、text、curkey、texttag。

四、总结反思

这个程序很好的练习学习了java swing，收获最大应该是这个虚拟键盘的设计，以前对于实现这个虚拟键盘完全不知道从何做起。如果是完全没有接触过java swing的同学直接下手做项目是非常困难的，我在已经做过项目的情况下还发现Java swing有许许多多陌生和的类和方法，好的办法是先有了对基础类大致的了解下，找一个做好的项目来进行修改，不会的再单独学习某个类的使用方法，变成自己的东西。有了这些基本的框架后就可以个性化的设计自己的作品了。
