<span><code>JTextArea</code>是显示纯文本的多行区域。</span>
<span>它旨在成为一个轻量级组件，可以与<code>java.awt.TextArea</code>类合作来提供源兼容性。</span>
<span>你可以找到信息，并使用所有文本组件的例子<a href="http://docs.oracle.com/javase/tutorial/uiswing/components/text.html">Using Text Components</a> ，在<em>Java教程</em>的部分<em>。</em></span>
<p> <span>该组件具有<code>java.awt.TextArea</code>类中找不到的<code>java.awt.TextArea</code> 。</span> <span>应咨询超类以获得更多功能。</span> <span>具有更多功能的替代多行文本课程是<code>JTextPane</code>和<code>JEditorPane</code> 。</span> </p>
<p> <span><code>java.awt.TextArea</code>内部处理滚动。</span> <span><code>JTextArea</code>的不同之处在于它不管理滚动，而是实现了swing <code>Scrollable</code>界面。</span> <span>如果需要滚动行为，则允许将其放置在<code>JScrollPane</code>内，如果不需要滚动则直接使用。</span> </p>
<p> <span><code>java.awt.TextArea</code>具有进行线包装的能力。</span> <span>这是由水平滚动政策控制的。</span> <span>由于滚动不是直接由<code>JTextArea</code>完成， <code>JTextArea</code>向后兼容性必须另外提供。</span> <span><code>JTextArea</code>具有用于线条换行的绑定属性，用于控制是否将换行。</span> <span>默认情况下，换行属性设置为false（不包装）。</span> </p>
<p> <span><code>java.awt.TextArea</code>具有用于确定优选大小的两个属性<code>rows</code>和<code>columns</code> 。</span> <span><code>JTextArea</code>使用这些属性来表示当放置在<code>JScrollPane</code>以匹配java.awt.TextArea提供的<code>java.awt.TextArea</code>时视口的首选大小。</span> <span><code>JTextArea</code>有需要显示的所有文本，使其正常功能的里面有什么较好大小<code>JScrollPane</code> 。</span> <span>如果<code>rows</code>或<code>columns</code>的值等于零，则沿该轴的优选尺寸用于沿相同轴的视口优选尺寸。</span> </p>
<p> <span><code>java.awt.TextArea</code>可以通过为TextEvent添加一个<code>TextListener</code>来<code>TextEvent</code>变化。</span> <span>在<code>JTextComponent</code>基组分，更改从模型经由广播<code>DocumentEvent</code>至<code>DocumentListeners</code> 。</span> <span>如果需要， <code>DocumentEvent</code>给出了更改的位置和更改的种类。</span> <span>代码片段可能如下所示：</span> </p>
<pre> <span>DocumentListener myListener = ??;
JTextArea myArea = ??;
myArea.getDocument().addDocumentListener(myListener);</span> </pre>
