用Eclipse开发的一点困惑，求关于Tree

[queenxxj]

要写一个文件系统的树
其实不是很难
可是程序有点大，想分为几个小部分作

看了一本书，说在swing下面有TreeModel可以使用
想请教一下在Eclipse下边有对应的吗
如果没有，自己写一个Eclipse下边的TreeModel是不是很麻烦呢

谢谢大家

Eclipse只是IDE，不提供任何库。
想要现成库的话，到sourceforge上去搜搜

你指的应该是swt，它的类库中是有个类叫Tree，和Swing中的JTree相对应给你一个简单的例子，是eclipse提供的

DefaultMutableTreeNode r;
JTree tree;
root = new DefaultMutableTreeNode("Root");
tree = new JTree(root);//首先创建一个有根的树
.....
//然后构建你的子树，这里假设用数组构建
r = new DefaultMutableTreeNode(data[0]);
for (int i = 2; i < data.length; i++)
r.add(new DefaultMutableTreeNode(data[i]));
最后把子树不断的插入到其父节点中，可以用parent.add(TreeNode son)方法插入，注意类型变换
