《Java编程思想》读书笔记(7)
Swing的确是MVC模式的一个优秀例子,它将接口(图形组件)和实现(当组件发生了某个事件之后,你要运行的代码)明明白白地分开来。Swing组件能通报在它身上可以发生什么事件,以及发生了什么事件。所以,如果你对某个事件不感兴趣,比如鼠标从按钮的上方经过,你完全可以不去理会这个事件。用这种方法能非常简洁优雅地解决事件驱动的问题,一旦你理解了其基本概念,你甚至可以去直接使用过去从未看到过的Swing组件。
为了对事件驱动编程进行学习,我们还是从一个简单的HelloWorld开始说起好了,正所谓“麻雀虽小,可五脏俱全”,越是细小的东西反而更能引人思考。不废话,先上代码(^o^

此外,Swing的功能非常强大,短短几行代码就能做很多事。但是,有些时候用手写代码创建GUI表单就不那么明智了;首先是太复杂,其次也不值得。Java和Swing的设计者们是想用语言和类库去支持GUI builder工具,然后让你用工具来简化编程。实际上只要知道布局是怎么一回事,以及事件该怎么处理就行了,懂不懂手写代码控制控件的摆放,其实并不重要。你完全可以选一个趁手的工具(毕竟Java的初衷就是想让你提高编程的效率)。
