java做一个简单的文件管理器（二）

继续上一篇，得到路径之后的操作该是什么样的呢？是对node的操作还是路径的操作。这里是需要思考的问题。由于路径是从node中一步一步得到，所以我们还是得从node去操作这些。

1. 实现操作的过程。

//节点的系列操作 比如是保存节点还是删除节点还是其它操作等等 因为其实对文件的操作本质上就是对节点的操作
public class FileNodeOperation {
private I_Node node = null;
private Vector<Vector<I_Node>> copiedList = new Vector<Vector<I_Node>>();//存储复制的文件节点
private Vector<I_Node> copyFile = null;
private Vector<I_Node> multiSelectedNodeList = new Vector<I_Node>();//存储选中的节点
private Vector<String> pastedFilePath = new Vector<String>();   //存储复制文件的路径
private static Vector<I_Node> searchNodeList = new Vector<I_Node>();//存储搜索结果的节点
int index = 0;        //标记是否有
private int pos = 0;    //标记文件名在路径中的位置
private int newNodeIndex = 0;
private static I_Node tempNode = new FileNode();

public static I_Node getTempNode() {
return tempNode;
    }

public FileNodeOperation() {

    }
//获取复制文件列表
private void setCopyList(I_Node copiedNode) {
if (index++ == 0) {
            copyFile = new Vector<I_Node>();
            copyFile.add(copiedNode);
            copiedList.add(copyFile);
            pos = copiedNode.getPath().lastIndexOf(File.separator);//获取文件节点名开始的索引
        }
        File[] copieFiles = copiedNode.getFile().listFiles();
if (copieFiles != null) {
for (File file : copieFiles) {
if (file.isDirectory()) {
                    copyFile = new Vector<I_Node>();
                    I_Node Tnode = new FileNode(file);
                    copyFile.add(Tnode);
                    copiedList.add(copyFile);
                    setCopyList(Tnode);  //递归
                } else {
                    copyFile = new Vector<I_Node>();

当我们在界面中显示每一个个文件信息记录的时候，该如何对这些记录进行反应呢？这个时候我们需要接触到对于按键和鼠标左键右键的事件。
