类 JDesktopPane

java.lang.Object
  java.awt.Component
      java.awt.Container
          javax.swing.JComponent
              javax.swing.JLayeredPane
                  javax.swing.JDesktopPane

所有已实现的接口：

ImageObserver, MenuContainer, Serializable, Accessible

public class JDesktopPane
   
   
   
   
   
extends JLayeredPane
   
   
   
   
   
   
   
   
   
   
implements Accessible
   
   
   
   
   

用于创建多文档界面或虚拟桌面的容器。用户可创建 JInternalFrame 对象并将其添加到 JDesktopPane。JDesktopPane 扩展了 JLayeredPane，以管理可能的重叠内部窗体。它还维护了对 DesktopManager 实例的引用，这是由 UI 类为当前的外观 (L&F) 所设置的。注意，JDesktopPane 不支持边界。

此类通常用作 JInternalFrames 的父类，为 JInternalFrames 提供一个可插入的 DesktopManager 对象。特定于 L&F 的实现 installUI 负责正确设置 desktopManager 变量。JInternalFrame 的父类是 JDesktopPane 时，它应该将其大部分行为（关闭、调整大小等）委托给 desktopManager。

有关此内容更多的文档和示例，请参阅 《The Java Tutorial》的 How to Use Internal Frames 一节。

警告：此类的已序列化对象与以后的 Swing 版本不兼容。当前序列化支持适用于短期存储，或适用于在运行相同 Swing 版本的应用程序之间进行 RMI（Remote Method Invocation，远程方法调用）。从 1.4 版本开始，已在 java.beans 包中添加了支持所有 JavaBeans^TM 长期存储的功能。请参见 XMLEncoder。
