<span>一个菜单的实现 - 一个包含<code>JMenuItem</code> s的弹出窗口，当用户在<code>JMenuBar</code>上选择一个项目时<code>JMenuBar</code> 。</span>
<span>除了<code>JMenuItem</code> s，一个<code>JMenu</code>也可以包含<code>JSeparator</code> s。</span>
<p> <span>实质上，菜单是一个带有关联的按钮<code>JPopupMenu</code> 。</span> <span>当按下“按钮”时，出现<code>JPopupMenu</code> 。</span> <span>如果“按钮”在<code>JMenuBar</code> ，菜单是顶级窗口。</span> <span>如果“按钮”是另一个菜单项，则<code>JPopupMenu</code>是“右 - 右”菜单。</span> </p>
<p> <span>菜单可以配置，并在一定程度上由<code><a href="Action.html">Action</a></code> s控制。</span> <span>使用带有菜单的<code>Action</code>除了直接配置菜单之外，还有很多好处。</span> <span>请参阅<a href="Action.html#buttonActions">Swing Components Supporting <code>Action</code></a>了解更多详情，您可以找到更多信息<a href="http://docs.oracle.com/javase/tutorial/uiswing/misc/action.html">How to Use Actions</a> ，在<em>Java教程</em>的部分。</span> </p>
