jtree 选择

[dzy_pb]

jtree 在编辑的时候，要控制焦点只能在当前编辑的结点上，不能选择其他结点，怎么做？？？

[IamHades]

监听当前节点失去焦点事件撒，一旦发现失去焦点，就重新设置让它获得焦点就ok了

[dzy_pb]

可以具体点吗？？？？

LZ 可以参考如下代码：

public class TreeEventHandle extends MouseAdapter implements
		TreeSelectionListener {
	// DefaultTreeModel treeModel = null;
	DefaultMutableTreeNode root;

		public TreeEventHandle() {
		try {
			jbInit();
		} catch (Exception exception) {
			exception.printStackTrace();
		}
	}

	private void jbInit() {
		root = new DefaultMutableTreeNode("系统", true);
				JTree tree = new JTree(root);
		tree.getSelectionModel().setSelectionMode(
				TreeSelectionModel.SINGLE_TREE_SELECTION);
		tree.addTreeSelectionListener(this);

		JScrollPane scrollPane = new JScrollPane();
		scrollPane.setViewportView(tree);

	}

	public void valueChanged(TreeSelectionEvent e) {
		JTree tree = (JTree) e.getSource();
		// 利用JTree的getLastSelectedPathComponent()方法取得目前选取的节点.
		DefaultMutableTreeNode selectionNode = (DefaultMutableTreeNode) tree
				.getLastSelectedPathComponent();

		if (selectionNode != null && selectionNode.isLeaf()) {
			JOptionPane.showMessageDialog(null, "叶子："
					+ selectionNode.toString());
			System.out.println("叶子：" + selectionNode.toString());
		}

	}
}

这个好象没有什么用！

[wunan320]

tree.setSelectionPath(path);
tree.scrollPathToVisible(path);
treeModel.nodeStructureChanged(node);

[dzy_pb]

如果在private class ListTreeTreeSelectionListener implements
TreeSelectionListener {
public void valueChanged(TreeSelectionEvent e) {
在这里可以通过e获old 接点，
tree.setSelectionPath(path); 后
又会触发一次valueChanged这样会死循环
