<span>默认的Caret实现。</span>
<span>插入符号以相关联的JTextComponent的CaretColor属性指定的颜色呈现为垂直线。</span>
<span>它可以以BlinkRate属性指定的速率闪烁。</span>
<p> <span>此实现期望异步通知的两个来源。</span> <span>定时器线程异步触发，并使插入符简单地重新绘制最近的边界框。</span> <span>插入符号也会跟踪文档的修改。</span> <span>通常情况下，由于某些鼠标或键盘事件，事件发送线程将发生。</span> <span>同步和异步文档更新的插入行为由<code>UpdatePolicy</code>属性控制。</span> <span>在任何情况下，新插入位置的重新绘制将发生在事件线程上，因为对事件线程的调用<code>modelToView</code> 。</span> </p>
<p> <span>插入符作为鼠标和焦点侦听器在已安装的文本组件上，并根据这些事件定义插入符语义。</span> <span>可以重新实现侦听器方法来改变语义。</span> <span>默认情况下，第一个鼠标按钮将用于设置焦点和插入位置。</span> <span>使用第一个鼠标按钮拖动鼠标指针将扫出模型中连续的选择。</span> <span>如果相关联的文本组件可编辑，则在获得焦点时插入符将变得可见，并且在焦点丢失时不可见。</span> </p>
<p> <span>与相关联的文本组件绑定的荧光笔用于默认呈现选择。</span> <span>选择外观可以通过提供一个画家来定制，用于亮点。</span> <span>默认情况下，将使用一个绘画器，它将呈现<code>SelectionColor</code>属性中关联的文本组件中指定的<code>SelectionColor</code> 。</span> <span>这可以通过重新实现<a href="../../../javax/swing/text/DefaultCaret.html#getSelectionPainter--"><code>getSelectionPainter</code></a>方法来轻松改变。</span> </p>
<p> <span>可以通过重新实现涂漆方法来实现定制的插入符号外观。</span> <span>如果油漆方法发生变化，还应重新实施损坏方法，以便对所需的区域进行重新绘制，以提供插入符号。</span> <span>插入符号扩展Rectangle类，该类用于保存上一次呈现插入符的位置的边界框。</span> <span>这使得插入符号在插入符号移动时不会调用modelToView，因此在模型更新和视图修复之间是不稳定的（即不能保证传递给DocumentListeners的顺序），因此可以以线程安全的方式重绘。</span> </p>
<p> <span>当插入位置更改时，魔术插入位置设置为null。</span> <span>定时器用于确定新位置（插入符号更改后）。</span> <span>当定时器触发时，如果魔术插入位置仍为空，则它将重置为当前插入符位置。</span> <span>任何改变插入位置并希望魔术插入位置保持不变的动作必须记住魔术插入位置，更改光标，然后将魔法插入符位置设置为其原始值。</span> <span>这有一个好处，只有想要魔术插入位置的动作（如开/关）需要知道。</span> </p>
<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经添加到<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>

<span>在文档更新中设置插入符号移动策略。</span>
<span>通常情况下，插入符号在文档中更新其在插入位置之前或之后插入的绝对位置，以及插入符号位置之前的删除。</span>
<span>“绝对位置”是指相对于文档开头的位置。</span>
<span>例如，如果在可编辑的文本组件中键入字符，则插入符号位置，插入符号会由于插入而移动到文档中的下一个绝对位置，如果输入了<code>BACKSPACE</code> ，则插入符号将由于删除字符而减小其绝对位置之前。</span>
<span>有时，关闭插入符位置更新可能会很有用，以便插入符在文档位置保持在相同的绝对位置，而不管任何文档更新。</span>
<p> <span>允许以下更新策略：</span> </p>
<ul>
<li> <span><code>NEVER_UPDATE</code> ：无论文档更新如何，插入符都保持在文档的绝对位置，除非文档长度由于删除而小于当前插入符号位置。</span> <span>在这种情况下，插入位置被调整到文档的末尾。</span> <span>使用此策略时，插入符并不会通过滚动关联的视图来尝试保持其可见。</span> </li>
<li> <span><code>ALWAYS_UPDATE</code> ：插入符号始终跟踪文档更改。</span> <span>对于常规更改，如果插入发生在当前位置之前或当前位置，则会增加其位置，如果在当前位置之前发生移除，则会减小位置。</span> <span>对于撤消/重做更新，它始终移动到发生更新的位置。</span> <span>插入符号也试图通过调用<code>adjustVisibility</code>方法来保持自己的可见性。</span> </li>
<li> <span><code>UPDATE_WHEN_ON_EDT</code> ：行为像<code>ALWAYS_UPDATE</code>如果文档更新在事件调度线程执行，并且像<code>NEVER_UPDATE</code>如果更新是在其他线程执行。</span> </li>
