用AWT来生成图形化用户界面时,组件和容器的概念非常重要。组件是各种各样的类,封装了图形系统的许多最小单位,例如按钮、窗口等等;而容器也是组件,它的最主要的作用是装载其它组件,但是象Panel这样的容器也经常被当作组件添加到其它容器中,以便完成杂的界面设计。布局管理器是java语言与其它编程语言在图形系统方面较为显著的区别,容器中各个组件的位置是由布局管理器来决定的,共有5种布局管理器,每种布局管理器都有自己的放置规律。事件处理机制能够让图形界面响应用户的操作,主要涉及到事件源、事件、事件处理者等三方,事件源就是图形界面上的组件,事件就是对用户操作的描述,而事件处理者是处理事件的类。因此,对于AWT中所提供的各个组件,我们都需要了解该组件经常发生的事件以及处理该事件的相应的监听器接口。-used to generate graphical user interfaces, components and packaging concept is very important. Components are a variety of categories, Packaging, a graphics system many smallest unit, such as buttons, windows, etc.; Also containers and components, and its main role is to carry other components, such as the Panel of containers are often used as components added to the other containers, in order to complete the miscellaneous sector face design. Layout Manager is java programming language and other languages in the graphics system is more notable distinction, packaging various components from the location of the layout manager to decide, there were five types of layout manager, each layout manager has its own laws placed.
