<span>A <code>SpringLayout</code>根据一组约束来布置其关联容器的子项。</span>
<span>见<a href="http://docs.oracle.com/javase/tutorial/uiswing/layout/spring.html">How to Use SpringLayout</a>在<em>Java教程</em>使用的例子<code>SpringLayout</code> 。</span>
<p> <span>由<code>Spring</code>对象表示的每个约束控制两个组件边缘之间的垂直或水平距离。</span> <span>边缘可以属于容器的任何孩子，也可以属于容器本身。</span> <span>例如，可以使用控制组件的西（左）和东（右）边之间的距离的约束来表示组件的允许宽度。</span> <span>组件的允许的<em>y</em>坐标可以通过限制组件的北（顶部）边缘与其容器的北边缘之间的距离来表示。</span> </p>
<p> <span><code>SpringLayout</code>控制的容器的所有子项以及容器本身都具有与之相关联的一组约束。</span> <span>这些约束由<code>SpringLayout.Constraints</code>对象表示。</span> <span>默认情况下， <code>SpringLayout</code>产生约束，使他们的相关组件具有最小，首选，和组件的最大返回大小<a href="../../java/awt/Component.html#getMinimumSize--"><code>Component.getMinimumSize()</code></a> ， <a href="../../java/awt/Component.html#getPreferredSize--"><code>Component.getPreferredSize()</code></a>和<a href="../../java/awt/Component.html#getMaximumSize--"><code>Component.getMaximumSize()</code>种</a>方法。</span> <span><em>x</em>和<em>y</em>的位置最初不受约束，以便约束它们之前的<code>Component</code>将定位在0,0相对于<code>Insets</code>父<code>Container</code> 。</span> </p>
<p> <span>您可以通过多种方式更改组件的约束。</span> <span>您可以使用<a href="../../javax/swing/SpringLayout.html#putConstraint-java.lang.String-java.awt.Component-int-java.lang.String-java.awt.Component-"><code>putConstraint</code>中的</a>一种方法来建立一个连接同一容器中两个组件边缘的弹簧。</span> <span>或者您可以使用<a href="../../javax/swing/SpringLayout.html#getConstraints-java.awt.Component-"><code>getConstraints</code></a>获取适当的<code>SpringLayout.Constraints</code>对象，然后修改其一个或多个弹簧。</span> <span>或者您可以使用<a href="../../javax/swing/SpringLayout.html#getConstraint-java.lang.String-java.awt.Component-"><code>getConstraint</code></a>获取组件特定边缘的弹簧，并进行修改。</span> <span>您还可以通过在将组件添加到其容器中（使用<a href="../../java/awt/Container.html#add-java.awt.Component-java.lang.Object-"><code>Container.add(Component, Object)</code></a> ） <code>SpringLayout.Constraints</code>对象，将自己的<code>SpringLayout.Constraints</code>对象与组件相关联。</span> </p>
<p> <span>表示每个约束的<code>Spring</code>对象具有最小值，优先级，最大值和当前值。</span> <span>根据<a href="../../javax/swing/Spring.html#sum-javax.swing.Spring-javax.swing.Spring-"><code>Spring.sum(javax.swing.Spring, javax.swing.Spring)</code></a>方法描述中给出的公式，弹簧的当前值位于最小值和最大值之间。</span> <span>当最小值，优选值和最大值相同时，当前值总是等于它们;</span> <span>这个不灵活的弹簧叫做<em>支柱</em> 。</span> <span>您可以使用工厂方法<a href="../../javax/swing/Spring.html#constant-int-"><code>Spring.constant(int)</code></a>创建支柱。</span> <span><code>Spring</code>类还提供了制造其他类型弹簧的工厂方法，包括依靠其他弹簧的弹簧。</span> </p>
<p> <span>在<code>SpringLayout</code> ，每个边的位置取决于另一个边缘的位置。</span> <span>如果随后添加约束以创建边缘的新约束，则先前的绑定被丢弃，并且边缘依赖于单个边缘。</span> <span>弹簧只能附在容器的边缘及其直立的儿童之间;</span> <span>当提供链接来自不同容器（内部或外部）的组件的边缘的<code>SpringLayout</code>时，SpringLayout的行为是未定义的。</span> </p>
<h3> <span>SpringLayout与其他布局管理器</span> </h3>
<blockquote>
<span>
<hr/> <strong>Note:</strong> Unlike many layout managers, <code>SpringLayout</code> doesn't automatically set the location of the components it manages. If you hand-code a GUI that uses <code>SpringLayout</code>, remember to initialize component locations by constraining the west/east and north/south locations. <p> Depending on the constraints you use, you may also need to set the size of the container explicitly. </p>
<hr/></span>
</blockquote>
<p> <span>尽管SpringLayout的<code>SpringLayout</code> ，它可以模拟大多数其他布局管理器的行为。</span> <span>对于某些功能，例如由<code>FlowLayout</code>提供的<code>FlowLayout</code> ，您需要创建<code>Spring</code>类的专用子类。</span> </p>
<p> <span><code>SpringLayout</code>还提供了一种解决许多困难的布局问题的方法，这些问题无法通过嵌套<code>Box</code> es的<code>Box</code>来解决。</span> <span>也就是说， <code>SpringLayout</code>尊重<code>LayoutManager2</code>合同，因此可以嵌套其他布局管理器 - 这种技术可以优于创建其他布局管理器所暗示的约束。</span> </p>
<p> <span>SpringLayout的布局操作的<code>SpringLayout</code>度在约束（和/或组件）的数量上是线性的。</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>
