<span>显示对象列表并允许用户选择一个或多个项目的组件。</span>
<span>单独的模型<code>ListModel</code>维护列表的内容。</span>
<p> <span>可以很容易地显示对象的数组或向量，使用<code>JList</code>构造函数自动构建只读<code>ListModel</code>实例为您提供：</span> </p>
<pre>  <span><code> // Create a JList that displays strings from an array String[] data = {"one", "two", "three", "four"}; JList&lt;String&gt; myList = new JList&lt;String&gt;(data); // Create a JList that displays the superclasses of JList.class, by // creating it with a Vector populated with this data Vector&lt;Class&lt;?&gt;&gt; superClasses = new Vector&lt;Class&lt;?&gt;&gt;(); Class&lt;JList&gt; rootClass = javax.swing.JList.class; for(Class&lt;?&gt; cls = rootClass; cls != null; cls = cls.getSuperclass()) { superClasses.addElement(cls); } JList&lt;Class&lt;?&gt;&gt; myList = new JList&lt;Class&lt;?&gt;&gt;(superClasses); // The automatically created model is stored in JList's "model" // property, which you can retrieve ListModel&lt;Class&lt;?&gt;&gt; model = myList.getModel(); for(int i = 0; i &lt; model.getSize(); i++) { System.out.println(model.getElementAt(i)); } </code></span> </pre>
<p> <span>甲<code>ListModel</code>可以直接提供给<code>JList</code>由一个构造的方式或<code>setModel</code>方法。</span> <span>内容不需要是静态的 - 项目的数量和项目的值可以随着时间的推移而改变。</span> <span>正确的<code>ListModel</code>实现通知已经添加到它的<code>javax.swing.event.ListDataListener</code> s的集合，每次发生更改。</span> <span>这些更改的特征在于<code>javax.swing.event.ListDataEvent</code> ，它标识已修改，添加或删除的列表索引的范围。</span> <span><code>JList</code>的<code>ListUI</code>负责与变化保持视觉呈现最新，通过监听模式。</span> </p>
<p> <span>简单，动态内容， <code>JList</code>程序可以使用<code>DefaultListModel</code>类来维护列表元素。</span> <span>该类实现了<code>ListModel</code>接口，并提供了一个类似<code>java.util.Vector</code>的API。</span> <span>需要更自定义<code>ListModel</code>程序可能希望子类化<code>AbstractListModel</code> ，它为管理和通知监听器提供了基本的支持。</span> <span>例如，只读实现<code>AbstractListModel</code> ：</span> </p>
<pre>  <span><code> // This list model has about 2^16 elements. Enjoy scrolling. ListModel&lt;String&gt; bigData = new AbstractListModel&lt;String&gt;() { public int getSize() { return Short.MAX_VALUE; } public String getElementAt(int index) { return "Index " + index; } }; </code></span> </pre>
<p> <span>一个的选择状态<code>JList</code>被另一个单独的模型，的一个实例管理<code>ListSelectionModel</code> 。</span> <span><code>JList</code>在构建中使用选择模型初始化，并且还包含查询或设置此选择模型的方法。</span> <span>另外， <code>JList</code>提供了便于管理选择的方便的方法。</span> <span>这些方法，例如<code>setSelectedIndex</code>和<code>getSelectedValue</code> ，是涵盖与选择模型交互的细节的覆盖方法。</span> <span>默认情况下， <code>JList</code>的选择模型被配置为允许每次选择项目的任意组合;</span> <span>选择模式<code>MULTIPLE_INTERVAL_SELECTION</code> 。</span> <span>选择模式可以直接在选型上更改，也可以通过<code>JList</code>的封面方式进行更改。</span> <span>响应用户手势更新选择模型的责任在于列表的<code>ListUI</code> 。</span> </p>
<p> <span>正确的<code>ListSelectionModel</code>实现通知每次发生更改选择时已添加到其中的<code>javax.swing.event.ListSelectionListener</code> s的集合。</span> <span>这些更改的特征是<code>javax.swing.event.ListSelectionEvent</code> ，它标识选择更改的范围。</span> </p>
<p> <span>收听列表选择更改的首选方法是直接添加<code>ListSelectionListener</code> s到<code>JList</code> 。</span> <span><code>JList</code>然后照顾听选择模型并通知你的听众的变化。</span> </p>
<p> <span>为了保持列表的视觉表示更新，聆听选择更改的责任在于列表的<code>ListUI</code> 。</span> </p>
<p> <span><a name="renderer"></a> <code>JList</code>中的单元格绘制由名为单元格渲染器的委托处理，作为<code>cellRenderer</code>属性安装在列表中。</span> <span>渲染器提供了一个<code>java.awt.Component</code> ，它像“橡皮图章”一样用于绘制单元格。</span> <span>每次单元格需要绘制时，列表的<code>ListUI</code>会向单元格渲染器询问组件，将其移动到位，并通过其<code>paint</code>方法绘制单元格的内容。</span> <span>使用<code>JLabel</code>组件渲染的默认单元格渲染器由列表的<code>ListUI</code> 。</span> <span>您可以使用以下代码替换您自己的渲染器：</span> </p>
<pre>  <span><code> // Display an icon and a string for each object in the list. class MyCellRenderer extends JLabel implements ListCellRenderer&lt;Object&gt; { final static ImageIcon longIcon = new ImageIcon("long.gif"); final static ImageIcon shortIcon = new ImageIcon("short.gif"); // This is the only method defined by ListCellRenderer. // We just reconfigure the JLabel each time we're called. public Component getListCellRendererComponent( JList&lt;?&gt; list, // the list Object value, // value to display int index, // cell index boolean isSelected, // is the cell selected boolean cellHasFocus) // does the cell have focus { String s = value.toString(); setText(s); setIcon((s.length() &gt; 10) ? longIcon : shortIcon); if (isSelected) { setBackground(list.getSelectionBackground()); setForeground(list.getSelectionForeground()); } else { setBackground(list.getBackground()); setForeground(list.getForeground()); } setEnabled(list.isEnabled()); setFont(list.getFont()); setOpaque(true); return this; } } myList.setCellRenderer(new MyCellRenderer()); </code></span> </pre>
<p> <span>单元格渲染器的另一个工作是帮助确定列表的大小信息。</span> <span>默认情况下，列表的<code>ListUI</code>通过询问单元格渲染器的每个列表项的首选大小来确定单元格的大小。</span> <span>这对于大型物品清单来说可能是昂贵的。</span> <span>为了避免这些计算，您可以在列表中设置<code>fixedCellWidth</code>和<code>fixedCellHeight</code> ，或者根据单个原型值自动计算这些值： <a name="prototype_example"></a></span> </p>
<pre>  <span><code> JList&lt;String&gt; bigDataList = new JList&lt;String&gt;(bigData); // We don't want the JList implementation to compute the width // or height of all of the list cells, so we give it a string // that's as big as we'll need for any cell. It uses this to // compute values for the fixedCellWidth and fixedCellHeight // properties. bigDataList.setPrototypeCellValue("Index 1234567890"); </code></span> </pre>
<p> <span><code>JList</code>不直接实现滚动。</span> <span>要创建一个滚动的列表，使其成为<code>JScrollPane</code>的视口视图。</span> <span>例如：</span> </p>
<pre>  <span>JScrollPane scrollPane = new JScrollPane(myList);

 // Or in two steps:
 JScrollPane scrollPane = new JScrollPane();
 scrollPane.getViewport().setView(myList);</span> </pre>
<p> <span><code>JList</code>不提供双击或三键（或N）鼠标点击的任何特殊处理，但如果您想对这些事件采取行动，可以轻松添加<code>MouseListener</code> 。</span> <span>使用<code>locationToIndex</code>方法来确定单击哪个单元格。</span> <span>例如：</span> </p>
<pre>  <span>MouseListener mouseListener = new MouseAdapter() {
     public void mouseClicked(MouseEvent e) {
         if (e.getClickCount() == 2) {
             int index = list.locationToIndex(e.getPoint());
             System.out.println("Double clicked on Item " + index);
          }
     }
 };
 list.addMouseListener(mouseListener);</span> </pre>
