Class JInternalFrame.JDesktopIcon

java.lang.Object

java.awt.Component

java.awt.Container

javax.swing.JComponent

javax.swing.JInternalFrame.JDesktopIcon

所有已实现的接口:

ImageObserver, MenuContainer, Serializable, Accessible

封装类:

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，因为在将来的Swing版本中，其功能将被移入JInternalFrame中。此类仅为UI对象可以显示桌面图标而公开。如果应用程序想要显示桌面图标，应创建一个JInternalFrame实例并将其图标化。

警告: 此类的序列化对象将不兼容未来的Swing版本。当前的序列化支持适用于短期存储或在运行相同Swing版本的应用程序之间的RMI。从1.4开始，已将所有JavaBeans的长期存储支持添加到java.beans包中。请参阅XMLEncoder。
