Suggestion: Populating Listbox with the folder and file

[shrivatsahosabettu]

I am following the code of yours to add images to list box, but before even trying that I want to convert the files and folders from the path to the list box. Not sure how to go ahead on this one.

Do I need to populate the data list first before even populating the tree as the treedata is converting to list box. or do I need to change my path to class structure?

I opened this here as the example which I am following is in your repository. Please let me know if I need to open this in PySimpleGUI Github

import PySimpleGUI as sg
import getpass, os, sys

default_path = os.path.join('C:\\', 'Users', getpass.getuser())
sg.set_options(font=('Roboto', 10))
back_path_holder = []
forward_path_holder = []
sg.theme('Dark Purple 4')


def list_files_and_folders(event, values, selected_folder):
    file_list = os.listdir(selected_folder)
    window['-TREE-'].update(file_list)
    print(file_list)


def prepare_header(data):
    for files_or_folders in data:
        treedata.Insert('', files_or_folders, files_or_folders, values=[], )


def common_functions(event, values):
    if back_path_holder:
        window['-BACK-'].update(disabled=False)
    else:
        window['-BACK-'].update(disabled=True)

    if forward_path_holder:
        window['-FORWARD-'].update(disabled=False)
    else:
        window['-FORWARD-'].update(disabled=True)

Not sure the question is, but

if you use the sg.Tree element, you have to convert your list into sg.TreeData firstly, then update the sg.Tree element, like

def list_files_and_folders(event, values, selected_folder):
    file_list = os.listdir(selected_folder)
    treedata = sg.TreeData()
    for i, file in enumerate(file_list):
        treedata.insert("", i, file, [] )
    window['-TREE-'].update(treedata)

or, if you use the sg,Listbox element, just update the sg.Listbox with your one-dimension file list.

def list_files_and_folders(event, values, selected_folder):
    file_list = os.listdir(selected_folder)
    window['-LISTBOX-'].update(file_list)

    window['-LISTBOX-'].update(file_list)

I think the first example suits to me. I am using the Tree. My project is about a status tracker of the files and folders. Where you can mark the status of the file/folder with the image as update in the list box saying completed, important, Remove, Need to see, etc.. These information I am planning to store in a file with Filepath as dictory key and file and inner dictionay key and these status as values. Basically dictionary of dictionary in the file. Hope this is not a complex one which cannot be done using PySimpleGUI.

Maybe you can refer this: https://github.com/jason990420/PySimpleGUI-Solution/issues/96

headings #0 is for the icon and text of heading #0, and you can put the filename and its status to values list when you insert each item into the treedata.

heading #0 or icon cannot be placed at other column and it is defined by tkinter.

treedata.insert(parent, key, text, values, icon=None)

Inserts a node into the tree. This is how user builds their tree, by Inserting Nodes This is the ONLY user callable method in the TreeData class

:param parent: the parent Node :type parent: (Node) :param key: Used to uniquely identify this node :type key: str | int | tuple | object :param text: The text that is displayed at this node's location :type text: (str) :param values: The list of values that are displayed at this node :type values: List[Any] :param icon: icon :type icon: str | bytes
