pysimplegui之tiee实例（附带github仓库地址地址）

本文主要是介绍pysimplegui之tiee实例（附带github仓库地址地址），对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

今天想写一个文件管理器，结果整了一下午，还是自己看的源代码少，分析别人代码少，最终还是看别人代码才找到错误原因。

    Demo program that will display a folder hierarchy with icons for the folders and files.

    This can be fixed easily enough by reusing the images within PySimpleGUI (enhancement request can be opened if you hit this problem)
