<span>对于在多个不同文本组件之间共享的键绑定，Action实现非常有用。</span>
<span>因为行动是共享的，它必须有一种方法来达到目标。</span>
<span>该类提供了支持来尝试查找要操作的文本组件。</span>
<span>获取组件的首选方法是通过接收到的ActionEvent。</span>
<span>如果getSource返回的对象可以缩小为一个文本组件，那么它将被使用。</span>
<span>如果action事件为空或不能缩小，则会尝试最后一个聚焦的文本组件。</span>
<span>这通过与JTextController结合使用来确定，JTextController安排用TextAction共享该信息。</span>
<p> <span><strong>警告：</strong>此类的序列化对象与将来的Swing版本不兼容。</span> <span>当前的序列化支持适用于运行相同版本的Swing的应用程序之间的短期存储或RMI。</span> <span>从1.4开始，对所有JavaBeans的长期存储的支持已被添加到<code>java.beans</code>包中。</span> <span>请参阅<a href="../../../java/beans/XMLEncoder.html" title="java.beans中的类"><code>XMLEncoder</code></a> 。</span> </p>
