/**
 * A lightweight object that provides many of the features of
 * a native frame, including dragging, closing, becoming an icon,
 * resizing, title display, and support for a menu bar.
 * For task-oriented documentation and examples of using internal frames,
 * see <a
 href="http://java.sun.com/docs/books/tutorial/uiswing/components/internalframe.html" target="_top">How to Use Internal Frames</a>,
 * a section in <em>The Java Tutorial</em>.
 *
 * <p>
 *
 * Generally,
 * you add <code>JInternalFrame</code>s to a <code>JDesktopPane</code>. The UI
 * delegates the look-and-feel-specific actions to the
 * <code>DesktopManager</code>
 * object maintained by the <code>JDesktopPane</code>.
 * <p>
 * The <code>JInternalFrame</code> content pane
 * is where you add child components.
 * So, to create a <code>JInternalFrame</code> that has a number of
 * buttons arranged 
 * with the content pane's default <code>BorderLayout</code> object,
 * you might do something like this:
 * <pre>
 *    JComponent c = (JComponent) internalFrame.getContentPane();
 *    c.add(new JButton(), BorderLayout.NORTH);
 *    c.add(new JButton(), BorderLayout.CENTER);
 * </pre>
 * The content pane is actually managed by an instance of
 * <code>JRootPane</code>,
 * which also manages a layout pane, glass pane, and 
 * optional menu bar for the internal frame. Please see the
 * <code>JRootPane</code> 
 * documentation for a complete description of these components.
 * <p>
 * For the keyboard keys used by this component in the standard look and
 * feel renditions, see the
 * <a href="doc-files/Key-Index.html#JInternalFrame"><code>JInternalFrame</code> key assignments</a>.
 * <p>
 * <strong>Warning:</strong>
 * Serialized objects of this class will not be compatible with
 * future Swing releases. The current serialization support is
 * appropriate for short term storage or RMI between applications running
 * the same version of Swing.  As of 1.4, support for long term storage
 * of all JavaBeans<sup><font size="-2">TM</font></sup>
 * has been added to the <code>java.beans</code> package.
 * Please see {@link java.beans.XMLEncoder}.
