public void uninstallUI(JComponent c)
installUI。这个方法被调用时,这个
UIComponent实例被作为指定组件的UI代理删除。这种方法应该撤消配置进行
installUI,小心留下的
JComponent实例在干净的状态(没有多余的听众,外观和感觉的特定属性的对象,等)。这应包括以下几个方面:
uninstallUI 方法重写,继承类

public void update(Graphics g, JComponent c)
paint(SynthContext,Graphics)方法。
在一般情况下,该方法不需要由子类重写。所有的外观和感觉的渲染代码应该在paint方法。
