    从阶级复制的描述： ComponentUI
    配置指定的组件适当的外观和感觉。这个方法被调用时， ComponentUI实例被安装在指定组件的UI代理。这种方法应该完全配置的组件外观和感觉，包括以下内容：
    1. 在组件上安装颜色、字体、边框、图标、不透明度等的默认属性值。只要有可能，属性值由客户端程序初始化应该不被重写。
    2. 安装一个LayoutManager组件上的必要。
    3. 创建/添加任何所需的子组件到组件。
    4. 在组件上创建/安装事件侦听器。
    5. 创建/安装为组件的检测和响应组件的属性PropertyChangeListener变化适当。
    6. 安装键盘UI（助记符，遍历等）的成分。
    7. 初始化任何适当的实例数据。
