javax.swing.tree
类 DefaultTreeCellRenderer

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JLabel
                  javax.swing.tree.DefaultTreeCellRenderer

所有已实现的接口：: ImageObserver, MenuContainer, Serializable, Accessible, SwingConstants, TreeCellRenderer

public class DefaultTreeCellRenderer
extends JLabel

implements TreeCellRenderer
extends JLabel
implements TreeCellRenderer

显示树中的条目。DefaultTreeCellRenderer 是透明的，除非为 paint 创建子类，否则不要更改它。有关使用此类自定义节点显示的示例，请参阅《The Java Tutorial》中的 How to Use Trees 一节。

实现注意事项：此类重写 invalidate、validate、revalidate、repaint 和 firePropertyChange 只是为了提高性能。如果不重写这些方法，这些经常调用的方法将执行那些对于默认树单元格渲染器来说不必要的代码路径。如果编写自己的渲染器，则要小心权衡重写这些方法的利弊。

警告：此类的已序列化对象与以后的 Swing 版本不兼容。当前的序列化支持适用于短期存储或运行相同 Swing 版本的应用程序之间的 RMI。从 1.4 版本开始，已在 java.beans 包中添加了支持所有 JavaBeans^TM 长期存储的功能。请参见 XMLEncoder。
