<span><code>LookAndFeel</code> ，顾名思义，封装外观。</span>
<span>除了安装外观，大多数开发人员不需要直接与<code>LookAndFeel</code>进行交互。</span>
<span>一般来说，创建自定义外观的开发人员只需要关注这个类。</span>
<p> <span>Swing建立在每个<code>JComponent</code>子类的基础上，具有特定的<code>ComponentUI</code>子类的实现。</span> <span><code>ComponentUI</code>通常被称为“ui”，“ui”或“look-feel delegate”。</span> <span><code>ComponentUI</code>子类负责提供组件的外观和特定功能。</span> <span>例如， <code>JTree</code>要求执行<code>ComponentUI</code>子类<code>TreeUI</code> 。</span> <span>具体<code>ComponentUI</code>子类的实现由<code>LookAndFeel</code>提供。</span> <span>每个<code>JComponent</code>子类通过<code>JComponent</code>方法<code>getUIClassID</code> <code>ComponentUI</code>子类。</span> </p>
<p> <span>每个<code>LookAndFeel</code>实现必须通过为从<code>getDefaults</code>返回的<code>UIDefaults</code>对象中的每个Swing的ui类ID指定一个值来提供适当的<code>ComponentUI</code>子类的<code>getDefaults</code> 。</span> <span>例如， <code>BasicLookAndFeel</code>使用<code>BasicTreeUI</code>作为具体实施<code>TreeUI</code> 。</span> <span>这是通过<code>BasicLookAndFeel</code>完成的，提供了键值对<code>"TreeUI"-"javax.swing.plaf.basic.BasicTreeUI"</code> ，在<code>UIDefaults</code>从<code>getDefaults</code>返回。</span> <span>有关如何获得<code>ComponentUI</code>子类的实现的详细信息，请参阅<a href="../../javax/swing/UIDefaults.html#getUI-javax.swing.JComponent-"><code>UIDefaults.getUI(JComponent)</code></a> 。</span> </p>
<p> <span>当安装<code>LookAndFeel</code>时， <code>UIManager</code>不会检查所有ui类ID是否存在条目。</span> <span>因此，如果当前的外观和感觉没有为特定的ui类id提供值，并且创建<code>JComponent</code>子类的实例，则会发生随机异常。</span> </p>
<h2> <span>外观和感觉的建议</span> </h2>
<span>如<code>UIManager</code>所述，每个<code>LookAndFeel</code>都有机会提供一组与开发人员和系统默认值分层的默认值。</span>
<span>一些Swing的组件需要外观和感觉来提供一组特定的默认值。</span>
<span>这些记录在需要特定默认值的类中。</span>
<h3> <span><a name="defaultRecommendation">ComponentUIs and defaults</a></span> </h3>
<span>所有<code>ComponentUIs</code>通常需要在设置各种属性<code>JComponent</code>的<code>ComponentUI</code>为其提供外观和感觉。</span>
<span>当<code>ComponentUI</code>在JComponent上时， <code>ComponentUI</code>会执行此<code>JComponent</code> 。</span>
<span>只有开发人员没有设置属性，才能设置属性。</span>
<span>对于非原始值，建议的<code>ComponentUI</code>仅改变在属性<code>JComponent</code>如果当前值是<code>null</code>或实现<code>UIResource</code> 。</span>
<span>如果当前值为<code>null</code>或实现<code>UIResource</code>则表明该属性尚未由开发人员设置，并且您可以自由更改该属性。</span>
<span>例如， <code>BasicButtonUI.installDefaults</code>仅改变对字体<code>JButton</code>如果从返回值<code>button.getFont()</code>是<code>null</code>或实现<code>UIResource</code> 。</span>
<span>另一方面，如果<code>button.getFont()</code>返回一个没有实现<code>UIResource</code>的<code>non-null</code>值，那么<code>BasicButtonUI.installDefaults</code>将不会更改<code>JButton</code>的字体。</span>
<p> <span>对于原始值，如<code>opaque</code> ，应调用方法<code>installProperty</code> 。</span> <span><code>installProperty</code>只有在开发人员尚未更改该值时才更改相应的属性。</span> </p>
<p> <span><code>ComponentUI</code>实现应该使用此类提供的各种安装方法，因为它们处理必要的检查并使用推荐的指导原则安装该属性。</span> </p>
<h3> <span><a name="exceptions"></a>例外</span> </h3>
<span>如果要更改的属性值为<code>null</code>或<code>UIResource</code>提供的所有安装方法<code>LookAndFeel</code>需要访问默认值。</span>
<span>例如，安装该字体将执行以下操作：</span>
<pre>  <span>JComponent c;
   Font font = c.getFont();
   if (font == null || (font instanceof UIResource)) {
       c.setFont(UIManager.getFont("fontKey"));
   }</span> </pre>
<span>如果字体是<code>null</code>或<code>UIResource</code> ，则使用键<code>fontKey</code>查询默认表。</span>
<span>所有<code>UIDefault's</code>获取方法抛出一个<code>NullPointerException</code>如果通过在<code>null</code> 。</span>
<span>因此，除非另有说明各个不同的安装方法<code>LookAndFeel</code>抛出<code>NullPointerException</code>如果当前值是<code>null</code>或<code>UIResource</code>和提供的默认密钥是<code>null</code> 。</span>
<span>此外，除非另有说明，所有的<code>install</code>方法抛出一个<code>NullPointerException</code>如果<code>null</code>组件中通过。</span>
