ComponentUI 
          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: 
           LayoutManager上安装LayoutManager。 PropertyChangeListener上创建/安装PropertyChangeListener,以便适当地检测和响应组件属性更改。 installUI在 
            ComponentUI 
           c - 正在安装此UI代理的组件 
           ComponentUI.uninstallUI(javax.swing.JComponent) , 
            JComponent.setUI(javax.swing.plaf.ComponentUI) , 
            JComponent.updateUI() 
           public void uninstallUI(JComponent c)
ComponentUI 
          installUI上完成的installUI 。 
           当这个UIComponent实例作为指定组件的UI委托被删除时,将调用此方法。 
           该方法应该撤消在installUI中执行的installUI ,小心使JComponent实例处于干净状态(没有无关的侦听器,外观特定属性对象等)。 
           这应该包括以下内容: 
           uninstallUI在 
            ComponentUI 
           c - 从中删除此UI代理的组件; 
            这个参数经常被忽略,但如果UI对象是无状态的并且被多个组件共享,则可能会被使用 
           ComponentUI.installUI(javax.swing.JComponent), 
            JComponent.updateUI() 
           protected void installDefaults(JComponent c)
protected void uninstallDefaults(JComponent c)
