java.lang.Object java.awt.Component java.awt.Container javax.swing.JComponent javax.swing.JLabel javax.swing.DefaultListCellRenderer
public class DefaultListCellRenderer
呈现列表中的一个项。
实现注意事项: 此类重写 invalidate
、validate
、revalidate
、repaint
、isOpaque
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列表单元格渲染器不必要的代码路径。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:此类的序列化对象将与以后的 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 JavaBeansTM 长期存储的功能。请参见 XMLEncoder
。
