封装类:

StyledEditorKit

       public static class StyledEditorKit.AlignmentAction extends StyledEditorKit.StyledTextAction
      

一个用于设置段落对齐的操作。这将为目标JEditorPane当前选定范围设置StyleConstants.Alignment属性。这是通过在与目标JEditorPane关联的样式文档上调用StyledDocument.setParagraphAttributes来完成的。

如果将目标文本组件指定为ActionEvent的源并且有一个命令字符串，则命令字符串将被解释为应该是StyleConstants.Alignment属性的合法值之一的整数。

警告: 该类的序列化对象将不兼容未来的Swing版本。当前的序列化支持适用于短期存储或在运行相同Swing版本的应用程序之间的RMI。从1.4开始，已将所有JavaBeans的长期存储支持添加到java.beans包中。请参阅XMLEncoder。
