如何在GtkTreeView小部件中列出目录层次结构? [英] How to list directory hierarchy in GtkTreeView widget?

问题描述

我正在尝试在pyGTK中生成一个分层目录列表.

I am trying to generate a hierarchical directory listing in pyGTK.

目前，我有以下目录树:

Currently, I have this following directory tree:

/root
    folderA
        - subdirA
            - subA.py
        - a.py

    folderB
        - b.py 

我编写了一个几乎可以正常工作的函数:

I have written a function that -almost- seem to work:

def go(root, piter=None):

    for filename in os.listdir(root):
        isdir = os.path.isdir(os.path.join(root, filename))
        piter = self.treestore.append(piter, [filename])    

        if isdir == True:
            go(os.path.join(root, filename), piter)

这是我运行该应用程序时得到的:

This is what i get when i run the app:

我还认为我的函数效率低下，我应该使用os.walk()，因为它已经为此目的而存在.

I also think my function is inefficient and that i should be using os.walk(), since it already exists for such purpose.

我该怎么办?用pyGTK生成目录树的正确/最有效的方法是什么?

How can I, and what is the proper/most efficient way of generating a directory tree with pyGTK?

---编辑---- 我最终使用的有效代码块是:

---edit---- the block of code i ended up using, that works, is:

parents = {}
        for dir, dirs, files in os.walk(root):
            for subdir in dirs:
                parents[os.path.join(dir, subdir)] = self.treestore.append(parents.get(dir, None), [subdir])
            for item in files:
                self.treestore.append(parents.get(dir, None), [item])

推荐答案

关于性能，

About the performance, this is a FAQ. About your algorithm: when you reach subdirA piter points to subdirA, at the next iteration when you reach a.py piter still points to subdirA.

如您所说，请使用os.walk.
