    描述从类别复制： ComponentUI
    适当地配置指定的组件的外观和感觉。当正在安装ComponentUI实例作为指定组件上的UI委托时，将调用此方法。该方法应该完全配置组件的外观，包括以下内容：
    1. 为组件上的颜色，字体，边框，图标，不透明度等安装默认属性值。只要有可能，由客户端程序初始化的属性值不应该被重写。
    2. 如有必要，请在LayoutManager上安装LayoutManager。
    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. 在PropertyChangeListener上创建/安装PropertyChangeListener，以便适当地检测和响应组件属性更改。
    6. 在组件上安装键盘UI（助记符，遍历等）。
    7. 初始化任何适当的实例数据。
