看下下面父节点A，B，C（ 后面是子节点）
A AA AB
B BA BB
C AA AB
我是在A中加了2个叶子AA，AB，然后把AA，AB，克隆一份加到C中，
我如何选中 A下面的叶子节点，C下面2个叶子也选中，如果A下面取消选中，C下面也取消选择呢？
我是在 JTree tree = new JTree();
tree.addTreeSelectionListener( new TreeSelectionListener()
{
public void valueChanged(TreeSelectionEvent e){
//我的方法改怎么写呢？
}
}；
------解决方案--------------------
是不是你在监听A的同时 也一起监听C呢 或者说用监听器C来监听A 试一试 我很久没有做过这一类题了

这儿也来一个吧 应该是达到你的要求了
- Java code
import java.util.Enumeration;import javax.swing.BoxLayout;import javax.swing.JFrame;import javax.swing.JPanel;import javax.swing.JScrollPane;import javax.swing.JTree;import javax.swing.event.TreeSelectionEvent;import javax.swing.event.TreeSelectionListener;import javax.swing.tree.DefaultMutableTreeNode;import javax.swing.tree.DefaultTreeModel;import javax.swing.tree.TreeNode;import javax.swing.tree.TreePath;class TreeFrame implements TreeSelectionListener { private JTree example = null; public TreeFrame() { DefaultMutableTreeNode root = new DefaultMutableTreeNode(" root ", true); DefaultMutableTreeNode a = new DefaultMutableTreeNode(" A "); root.add(a); a.add(new DefaultMutableTreeNode(" AA ")); a.add(new DefaultMutableTreeNode(" AB ")); DefaultMutableTreeNode b = new DefaultMutableTreeNode(" B "); root.add(b); b.add(new DefaultMutableTreeNode(" BA ")); b.add(new DefaultMutableTreeNode(" BB ")); DefaultMutableTreeNode c = new DefaultMutableTreeNode(" C "); root.add(c); c.add(new DefaultMutableTreeNode(" AA ")); c.add(new DefaultMutableTreeNode(" AB ")); example = new JTree(root); example.addTreeSelectionListener(this); JPanel panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.X_AXIS)); panel.add(new JScrollPane(example)); JFrame frame = new JFrame(" JTreeDemo "); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setContentPane(panel); frame.setSize(250, 400); frame.setVisible(true); } public void valueChanged(TreeSelectionEvent e) { example.expandPath(e.getPath()); DefaultMutableTreeNode dm = (DefaultMutableTreeNode) e.getPath() .getLastPathComponent(); for (Enumeration em = dm.children(); em.hasMoreElements();) { TreeNode n = (TreeNode) em.nextElement(); TreePath visiblePath = new TreePath(((DefaultTreeModel) example .getModel()).getPathToRoot(n)); example.addSelectionPath(visiblePath); } }}public class TreeTest { public static void main(String[] args) { new TreeFrame(); }}

不太懂这个，期待高手尽快出现，希望楼主早点解决难题。
帮顶一下

不懂 绑定 顺便借点分

嘿嘿 在5楼那哥们基础上改了一下 不知道是楼主的要的不
- Java code
public void valueChanged(TreeSelectionEvent e) { DefaultMutableTreeNode dm = (DefaultMutableTreeNode) e.getPath().getLastPathComponent(); DefaultMutableTreeNode root = (DefaultMutableTreeNode) example.getModel().getRoot(); for (Enumeration em = dm.children(); em.hasMoreElements();) { TreeNode n = (TreeNode) em.nextElement(); for (Enumeration rootem = root.breadthFirstEnumeration(); rootem.hasMoreElements();) { TreeNode rootn = (TreeNode) rootem.nextElement(); if (String.valueOf(n).equals(String.valueOf(rootn))) { TreePath path = new TreePath(((DefaultTreeModel) example.getModel()).getPathToRoot(rootn)); example.addSelectionPath(path); } } TreePath visiblePath = new TreePath(((DefaultTreeModel) example.getModel()).getPathToRoot(n)); example.addSelectionPath(visiblePath); } }
