|

<span><code>FileView</code>定义了一个抽象类，可以实现为文件选择器提供File的UI <code>File</code> 。</span>
|
||
<span>每个L＆F <code>JFileChooserUI</code>对象实现此类来传回正确的图标，并对该L＆F特定的类型描述。</span>
|
||
<span>例如，Microsoft Windows L＆F返回用于目录和通用文件的通用Windows图标。</span>
|
||
<span>此外，您可能希望提供您自己的<code>FileView</code> <code>JFileChooser</code>以返回不同的图标或附加信息使用<a href="../../../javax/swing/JFileChooser.html#setFileView-javax.swing.filechooser.FileView-"><code>JFileChooser.setFileView(javax.swing.filechooser.FileView)</code></a> 。</span>
|
||
<p> <span><code>JFileChooser</code>首先看看是否有一个用户定义<code>FileView</code> ，如果有的话，它从那里获取类型信息。</span> <span>如果<code>FileView</code>为任何方法返回<code>null</code> ，则<code>JFileChooser</code>然后使用L＆F特定视图来获取信息。</span> <span>因此，举例来说，如果你提供了一个<code>FileView</code>类返回<code>Icon</code>为JPG文件，并返回<code>null</code>图标所有其他文件，该UI的<code>FileView</code>将为其他所有文件提供默认图标。</span> </p>
|
||
<p> <span>有关简单文件视图的示例实现，请参阅<code><i>yourJDK</i>/demo/jfc/FileChooserDemo/ExampleFileView.java</code> 。</span> <span>有关更多信息和示例，请参阅<a href="http://docs.oracle.com/javase/tutorial/uiswing/components/filechooser.html">How to Use File Choosers</a> <em>“Java教程</em> ”中<em>的</em>一节。</span> </p>
