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()

Screenshot, Sketch, or Drawing

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.

I didn't use the sg.Pane in any of my GUI, so not sure what it for, also anything wrong.

Line 14200 in source code of PySimpleGUI 4.57.0, it is clear that no TkScrollableFrame or TkFixedFrame used, or it replace original settings for sg.Column.

                for pane in element.PaneList:
                    pane.Widget = pane.TKColFrame = tk.Frame(element.PanedWindow)

It looks like some of options in sg.Column not work under sg.Pane, like

• scrollable
• vertical_scroll_only
• size
• right_click_menu
• maybe more options, not confirmed.
