Using PySimpleGUI to divide the window in columns gives an error

Question

I am tring to construct a GUi that would display two columns: one column would have all the input fields and listboxes, the second column would display some data from pandas dataframe.

I thought it would be a good idea to do this using Frames, but I am running into an error when trying to create a Frame:

layout = [sg.Frame('Input data',[[
          sg.Text('Input:'),      
          sg.Input(do_not_clear=False),      
          sg.Button('Read'), sg.Exit(),
          sg.Text('Alternatives:'),
          sg.Listbox(values=('alternatives...', ''), size=(30, 2), key='_LISTBOX_')]])]

Result:

TypeError: AddRow() argument after * must be an iterable, not Frame

How to fix this?

I am thinking if it is possible to define columns first, using Frame, and then putting the columns into the definition of layout?

which line gives error message? Always show it in question (not in comment) — furas, Jul 17 '19 at 10:58
you could create minimal working example with your problem so we could run it and search solution. — furas, Jul 17 '19 at 10:59

You have to use [[ ]]

layout = [[

]]

External [ ] means all data, internal [ ] means first row - even if you need only one row.

Working example:

import PySimpleGUI as sg

layout = [[
    sg.Frame('Input data',[[
          sg.Text('Input:'),      
          sg.Input(do_not_clear=False),      
          sg.Button('Read'), sg.Exit(),
          sg.Text('Alternatives:'),
          sg.Listbox(values=('alternatives...', ''), size=(30, 2), key='_LISTBOX_')
    ]])
]]

window = sg.Window('App', layout)
event, values = window.Read()
window.Close()

Spot on correct! All layouts in PySimpleGUI are a "list of lists of elements". That's true for all of the "Container Elements" including Column, Frame, etc. They all take that same [ [ ] ] format. – Mike from PSG Jul 17 '19 at 13:23
@MikeyB it almost the same - I called it "list of rows of elements" :) – furas Jul 17 '19 at 13:37

Correct you are. List of rows of Elements is exactly what they are. – Mike from PSG Jul 17 '19 at 16:08
