The two <code>Component</code>s are graphically divided based on the look and feel implementation, and the two <code>Component</code>s can then be interactively resized by the user. Information on using <code>JSplitPane</code> is in <ahref="http://java.sun.com/docs/books/tutorial/uiswing/components/splitpane.html">How to Use Split Panes</a> in <em>The Java Tutorial</em>. <p> The two <code>Component</code>s in a split pane can be aligned left to right using <code>JSplitPane.HORIZONTAL_SPLIT</code>, or top to bottom using <code>JSplitPane.VERTICAL_SPLIT</code>. The preferred way to change the size of the <code>Component</code>s is to invoke <code>setDividerLocation</code> where <code>location</code> is either the new x or y position, depending on the orientation of the <code>JSplitPane</code>. <p> To resize the <code>Component</code>s to their preferred sizes invoke <code>resetToPreferredSizes</code>. <p> When the user is resizing the <code>Component</code>s the minimum size of the <code>Components</code> is used to determine the maximum/minimum position the <code>Component</code>s can be set to. If the minimum size of the two components is greater than the size of the split pane the divider will not allow you to resize it. To alter the minimum size of a <code>JComponent</code>, see <A HREF="../../javax/swing/JComponent.html#setMinimumSize(java.awt.Dimension)"><CODE>JComponent.setMinimumSize(java.awt.Dimension)</CODE></A>. <p> When the user resizes the split pane the new space is distributed between the two components based on the <code>resizeWeight</code> property. A value of 0, the default, indicates the right/bottom component gets all the space, where as a value of 1 indicates the left/top component gets all the space. <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#JSplitPane">JSplitPane</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/JSplitPane.html#setDividerLocation(double)"><CODE>setDividerLocation(double)</CODE></A>, <A HREF="../../javax/swing/JSplitPane.html#resetToPreferredSizes()"><CODE>resetToPreferredSizes()</CODE></A>, <A HREF="../../serialized-form.html#javax.swing.JSplitPane">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/JSplitPane.AccessibleJSplitPane.html">JSplitPane.AccessibleJSplitPane</A></B></CODE><BR> This class implements accessibility support for the <code>JSplitPane</code> class.</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>⌨️ 快捷键说明
