Detailed Description

I am trying to get the items within a column to expand in the x-Axis. Naturally I decided to add the Column within a Pane, only to notice that the scrollable feature of the column vanishes once it is inside the pane. Is there a way to force a scrollable column within a pane?

Code To Duplicate

import PySimpleGUI as sg    # pip install pysimplegui

right_list = [[sg.Button(f'Test Stuff {val}', expand_x=True)] for val in range(40)]

left_list = [[sg.Button(f'Test Stuff {val}', expand_x=True)] for val in range(40)]

layout = [[
    sg.Column(left_list, expand_x=True, justification='c', scrollable=True, vertical_scroll_only=True),
    sg.Pane([
        sg.Column(right_list, expand_x=True, justification='c', scrollable=True, vertical_scroll_only=True)],
    orientation='h', relief=sg.RELIEF_SUNKEN, key='-P-')
]]

window = sg.Window('Indexing Options', layout, border_depth=0, modal=True, finalize=True, size=(600, 600))
window['-P-'].expand(True, True, True)

while True:
    event, values = window.read()
    print(event, values)
    if event == sg.WIN_CLOSED:
        break

window.close()

As you can see on the image, the left side is a plain column that is nicely scrollable, except with the Buttons within there not streching to the X-Axis. Using the Column inside a Pane seems to allow the Buttons to strech to the X-Axis, but it also removes the scrolling feature of the column sadly.

Watcha Makin?

Hehe, same as the last time, working on a custom Image Converter for my little image file format for embedded systems. I'm tacking the custom indexed colors option, where I will need to be able to list up to 256 different colors, so a scrollable column seemed logical then to me. tool_screenshot
