The methods in this interface are just <i>covers</i> for the JRootPane properties, e.g. <code>getContentPane()</code> is generally implemented like this:<pre> public Container getContentPane() { return getRootPane().getContentPane(); } </pre> This interface serves as a <i>marker</i> for Swing GUI builders that need to treat components like JFrame, that contain a single JRootPane, specially. For example in a GUI builder, dropping a component on a RootPaneContainer would be interpreted as <code>frame.getContentPane().add(child)</code>.<P><DL><DT><B>See Also: </B><DD><A HREF="../../javax/swing/JRootPane.html"><CODE>JRootPane</CODE></A>, <A HREF="../../javax/swing/JFrame.html"><CODE>JFrame</CODE></A>, <A HREF="../../javax/swing/JDialog.html"><CODE>JDialog</CODE></A>, <A HREF="../../javax/swing/JWindow.html"><CODE>JWindow</CODE></A>, <A HREF="../../javax/swing/JApplet.html"><CODE>JApplet</CODE></A>, <A HREF="../../javax/swing/JInternalFrame.html"><CODE>JInternalFrame</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../java/awt/Container.html">Container</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/RootPaneContainer.html#getContentPane()">getContentPane</A></B>()</CODE><BR> Returns the contentPane.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../java/awt/Component.html">Component</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/RootPaneContainer.html#getGlassPane()">getGlassPane</A></B>()</CODE><BR> Returns the glassPane.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../javax/swing/JLayeredPane.html">JLayeredPane</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/RootPaneContainer.html#getLayeredPane()">getLayeredPane</A></B>()</CODE><BR> Returns the layeredPane.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../javax/swing/JRootPane.html">JRootPane</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/RootPaneContainer.html#getRootPane()">getRootPane</A></B>()</CODE><BR> Return this component's single JRootPane child.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/RootPaneContainer.html#setContentPane(java.awt.Container)">setContentPane</A></B>(<A HREF="../../java/awt/Container.html">Container</A> contentPane)</CODE><BR> The "contentPane" is the primary container for application specific components.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/RootPaneContainer.html#setGlassPane(java.awt.Component)">setGlassPane</A></B>(<A HREF="../../java/awt/Component.html">Component</A> glassPane)</CODE><BR> The glassPane is always the first child of the rootPane and the rootPanes layout manager ensures that it's always as big as the rootPane.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> void</CODE></FONT></TD><TD><CODE><B><A HREF="../../javax/swing/RootPaneContainer.html#setLayeredPane(javax.swing.JLayeredPane)">setLayeredPane</A></B>(<A HREF="../../javax/swing/JLayeredPane.html">JLayeredPane</A> layeredPane)</CODE><BR> A Container that manages the contentPane and in some cases a menu bar.</TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== -->⌨️ 快捷键说明
