For task-oriented documentation and examples of using internal frames, see <ahref="http://java.sun.com/docs/books/tutorial/uiswing/components/internalframe.html">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> <code>contentPane</code> is where you add child components. So, to create a <code>JInternalFrame</code> that has a number of buttons arranged with a <code>BorderLayout</code> object, you might do something like this: <pre> JComponent c = (JComponent) frame.getContentPane(); c.setLayout(new BorderLayout()); c.add(new JButton(), BorderLayout.NORTH); c.add(new JButton(), BorderLayout.CENTER); </pre> The <code>contentPane</code> is actually managed by an instance of <code>JRootPane</code>, which also manages a <code>layoutPane</code>, <code>glassPane</code>, and optional <code>menuBar</code> for the 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 (L&F) renditions, see the <a href="doc-files/Key-Index.html#JInternalFrame">JInternalFrame</a> key assignments. <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. A future release of Swing will provide support for long term persistence.<P><DL><DT><B>See Also: </B><DD><A HREF="../../javax/swing/JDesktopPane.html"><CODE>JDesktopPane</CODE></A>, <A HREF="../../javax/swing/DesktopManager.html"><CODE>DesktopManager</CODE></A>, <A HREF="../../javax/swing/JInternalFrame.JDesktopIcon.html"><CODE>JInternalFrame.JDesktopIcon</CODE></A>, <A HREF="../../javax/swing/JRootPane.html"><CODE>JRootPane</CODE></A>, <A HREF="../../serialized-form.html#javax.swing.JInternalFrame">Serialized Form</A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><A NAME="inner_class_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Inner Class Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected class</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/JInternalFrame.AccessibleJInternalFrame.html">JInternalFrame.AccessibleJInternalFrame</A></B></CODE><BR> This class implements accessibility support for the <code>JInternalFrame</code> class.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static class</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/JInternalFrame.JDesktopIcon.html">JInternalFrame.JDesktopIcon</A></B></CODE><BR> This component represents an iconified version of a JInternalFrame.</TD></TR></TABLE> <A NAME="inner_classes_inherited_from_class_javax.swing.JComponent"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Inner classes inherited from class javax.swing.<A HREF="../../javax/swing/JComponent.html">JComponent</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../javax/swing/JComponent.AccessibleJComponent.html">JComponent.AccessibleJComponent</A></CODE></TD></TR></TABLE> <A NAME="inner_classes_inherited_from_class_java.awt.Container"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Inner classes inherited from class java.awt.<A HREF="../../java/awt/Container.html">Container</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../java/awt/Container.AccessibleAWTContainer.html">Container.AccessibleAWTContainer</A></CODE></TD></TR></TABLE> <A NAME="inner_classes_inherited_from_class_java.awt.Component"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Inner classes inherited from class java.awt.<A HREF="../../java/awt/Component.html">Component</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../java/awt/Component.AccessibleAWTComponent.html">Component.AccessibleAWTComponent</A></CODE></TD></TR></TABLE> <!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected boolean</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/JInternalFrame.html#closable">closable</A></B></CODE><BR> The frame can be closed.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../java/lang/String.html">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/JInternalFrame.html#CONTENT_PANE_PROPERTY">CONTENT_PANE_PROPERTY</A></B></CODE><BR> Bound property name.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>protected <A HREF="../../javax/swing/JInternalFrame.JDesktopIcon.html">JInternalFrame.JDesktopIcon</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/JInternalFrame.html#desktopIcon">desktopIcon</A></B></CODE><BR> The icon that is displayed when the frame is iconized.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static <A HREF="../../java/lang/String.html">String</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/JInternalFrame.html#FRAME_ICON_PROPERTY">FRAME_ICON_PROPERTY</A></B></CODE>⌨️ 快捷键说明
