CDK has the CDKFSELECT widget.
It displays a list of directories and files, that might work for you, or the source code of CDKFSELECT might be leveraged for your own custom written solution.

The dialog program (which has a documented library interface) has a "tree" widget. The program works with (n)curses, and unlike CDK, is suitable for use with UTF-8.
UPDATE: 2020-10-01 - I wrote my answer back in 2010, when I wrote a tree widget for Urwid since I couldn't find anything. Urwid still has the tree widget, but these days, I would look at Python's prompt-toolkit or one of the alternatives.

“我正在尝试编写一个显示文件夹树的组件”
CDK 有
CDKFSELECT小部件。它显示可能适合您的目录和文件列表，或者
CDKFSELECT 的源代码可用于您自己的自定义编写
解决方案。

dialog程序（具有文档化的库接口）有一个 "tree" 小部件。该程序与 (n)curses 一起使用，与 CDK 不同，它适合与UTF-8。它还有一个 file(/directory ) 选择小部件。
还有
wcd（尽管就像mc一样，的可重用性库不确定）。然而，这是OP可能想要的一个很好的例子：关于
urwid，这是有争议的。在幕后你可能实际上并没有诅咒。就其价值而言，treeview 脚本的屏幕截图：并且在我的 Debian/测试系统上，该脚本不使用 ncurses。它是硬编码的（即使用
raw_display）。The

There's also
wcd(though likemc, reusability of the library is uncertain). However, it is a good example of what OP probably wants:Regarding
urwid, that's debatable. Under the hood you may not actually have curses. For what it's worth, a screenshot of the treeview script:and on my Debian/testing system, the script doesn't use ncurses. It's hardcoded (i.e., using
raw_display).Urwid 有一个树形小部件，FWIW。
更新：2020-10-01 - 我在 2010 年写了我的答案，当时我为 Urwid 编写了一个树小部件，因为我找不到任何东西。 Urwid 仍然有树小部件，但这些天，我会看看 Python 的提示工具包 或 替代方案之一。
Urwid has a tree widget, FWIW.

查看午夜指挥官源代码 (http://www.midnight-commander.org/)它有一个树存储小部件。
Look at the Midnight commander source code (http://www.midnight-commander.org/) It has a tree store widget.
