e1027. converting a node in a jtree component to a treepath.txt

这里面包含了一百多个JAVA源文件

// If expanded, return only paths of nodes that are expanded.
    public TreePath[] getPaths(JTree tree, boolean expanded) {
        TreeNode root = (TreeNode)tree.getModel().getRoot();

        List list = new ArrayList();
    
        // Traverse tree from root adding treepaths for all nodes to list
        getPaths(tree, new TreePath(root), expanded, list);
    
        // Convert list to array
        return (TreePath[])list.toArray(new TreePath[list.size()]);
    }
    public void getPaths(JTree tree, TreePath parent, boolean expanded, List list) {
        // Return if node is not expanded
        if (expanded && !tree.isVisible(parent)) {
            return;
        }
    
        // Add node to list
        list.add(parent);
    
        // Create paths for all children
        TreeNode node = (TreeNode)parent.getLastPathComponent();
        if (node.getChildCount() >= 0) {
            for (Enumeration e=node.children(); e.hasMoreElements(); ) {
                TreeNode n = (TreeNode)e.nextElement();
                TreePath path = parent.pathByAddingChild(n);
                getPaths(tree, path, expanded, list);
            }
        }
    }
