"""
    A PySimpleGUI or PySimpleGUIQt demo program that will display a folder heirarchy with icons for the folders and files.
    Note that if you are scanning a large folder then tkinter will eventually complain abouit too many bitmaps and crash
    Getting events back from clicks on the entries works for PySimpleGUI, but appears to not be implemented in PySimpleGUIQt
    If you need tree events using PySimpleGUIQt then post an Issue on the GitHub http://www.PySimpleGUI.com
