[Question] Unmodifiable (seemingly) Column padding

まず、提供されている Python 再現コードを PySimpleGUI 3.11.6 および tkinter 8.6.13 で実行し、ネストされた Column 要素と Window の element_padding 設定に注目します。Issue にはソースファイルもテストも記載されていません。可視の間隔を設定可能かどうかを判断し、その動作を文書化または修正することで完了となります。

Troubleshooting

These items may solve your problem. Please check those you've done by changing - [ ] to - [X]

• Searched main docs for your problem www.PySimpleGUI.org
• Looked for Demo Programs that are similar to your goal. It is recommend you use the Demo Browser! Demos.PySimpleGUI.org
• None of your GUI code was generated by an AI algorithm like GPT
• If not tkinter - looked for Demo Programs for specific port
• For non tkinter - Looked at readme for your specific port if not PySimpleGUI (Qt, WX, Remi)
• Run your program outside of your debugger (from a command line)
• Searched through Issues (open and closed) to see if already reported Issues.PySimpleGUI.org
• Have upgraded to the latest release of PySimpleGUI on PyPI (lastest official version)
• Tried using the PySimpleGUI.py file on GitHub. Your problem may have already been fixed but not released

Detailed Description

The sg.Column element seems to have some unmodifiable padding that is not removed by setting sg.Window's element_padding parameter to (0, 0). If same-width sg.Column's are nested with colored backgrounds (code attached), it becomes easily observable by naked eye.

Code To Duplicate

A short program that isolates and demonstrates the problem (Do not paste your massive program, but instead 10-20 lines that clearly show the problem)

import PySimpleGUI as psg


layout = [[
    psg.TabGroup(
        layout=[[
            psg.Tab(
                'Test',
                layout=[[
                    psg.Column(
                        layout=[[
                            psg.Column(
                                layout=[[psg.Column(
                                    layout=[[psg.Text('test', pad=(0, 0))]],
                                    size=(400, 50),
                                    background_color='green',
                                    pad=(0, 0),
                                )]],
                                size=(400, 100),
                                background_color='blue',
                                pad=(0, 0),
                            )
                        ]],
                        size=(400, 400),
                        background_color='red',
                        pad=(0, 0),
                    )
                ]],
            ),
        ]],
        background_color='violet',
        pad=(0, 0)
    )
]]

window = psg.Window('Test', layout, size=(500, 500), margins=(0, 0), border_depth=0, element_padding=(0, 0))

while True:
    event, values = window.read()
    if event in (psg.WIN_CLOSED, 'Exit'):
        break
window.close()
