more than one file type in pysimplegui-CodePudding

The documentation defines file_types parameter as Tuple[Tuple[str,str]] Does it mean that only one tuple possible? And only one filetype?

It does not work for me with two tuples and two extensions and one tuple and a string of extensions.

sg.FilesBrowse("COMEDY", file_types= (("mkv","*.mkv"),("avi","*.avi")),initial_folder=comedy_PATH)

sg.FilesBrowse("COMEDY", file_types= (("video files","*.mkv *.avi")),initial_folder=comedy_PATH)

sg.FilesBrowse("COMEDY", file_types= (("video files",".mkv .avi")),initial_folder=comedy_PATH)

I don't get errors I get the empty list. With just one extension, it works, as tuple inside a tuple.

any suggestions?

CodePudding user response：

A comma missed in your file types, it will be Tuple[str, str], not Tuple[Tuple[str, str]]

import PySimpleGUI as sg

type_1 = (
    ("All JPG Files","*.jpg"),
    ("All PNG Files","*.png"),
)
type_2 = (
    ("All Picture Files", "*.jpg *.png"),    # A comma missed in your code
)
type_3 = (
    ("All Picture Files", ".jpg .png"),      # A comma missed in your code
)

layout = [
    [sg.Input(), sg.FilesBrowse(file_types=type_1)],
    [sg.Input(), sg.FilesBrowse(file_types=type_2)],
    [sg.Input(), sg.FilesBrowse(file_types=type_3)],
]
sg.Window('Title', layout).read(close=True)
