          javax.swing.JComponent
              javax.swing.JInternalFrame.JDesktopIcon

所有已实现的接口：

ImageObserver, MenuContainer, Serializable, Accessible

正在封闭类：

JInternalFrame

public static class JInternalFrame.JDesktopIcon
extends JComponent
implements Accessible

此组件表示 JInternalFrame 的图标化版本。Swing 应用程序不应使用此 API，因为随着其功能被移入 JInternalFrame，在以后的 Swing 版本中不会再出现此 API。此类只是公共的，所以 UI 对象可以显示桌面图标。如果应用程序要显示桌面图标，那么它应该创建一个 JInternalFrame 实例并将其图标化。

警告：此类的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。
