PySimpleGUI RELIEF_SUNKEN 在项目标记为可见时展开，但在标记为不可见时不收缩

Question

我是 PYSimpleGUI 和 python 一般 GUI 编程的新手。我做了一个简单的设置，我想根据需要扩展和收缩。一旦元素被标记为可见然后不可见，有没有办法让第 3 张图片类似于第 1 张图片？

图3的浮雕还在扩大。有没有办法让它再次收缩？谢谢！

请看下面的代码：

import PySimpleGUI as sg

def mkWindow():
    # Layout for the Advanced relief
    layout = [
        [sg.Frame(layout=[
            [(sg.Text('Show Advanced Settings', size=[25, 1]))],
            [sg.Radio('No', "RADIO2", key='_radio_no2_', enable_events=True, default=True, size=(5,1)), sg.Radio('Yes', "RADIO2", enable_events=True, key='_radio_yes2_')],
            [(sg.Output(key='_out_', size=[25, 27], visible=False))]], title='Advanced',title_color='red', relief=sg.RELIEF_SUNKEN)]]

    window = sg.Window('Output Test', layout, finalize=True)

    while True:
        event, wvalues = window.read()
        if(event=='_radio_yes2_'):
            window.Element('_out_').Update(visible=True)
            
        if(event=='_radio_no2_'):
            window.Element('_out_').Update(visible=False)

        if(event==sg.WIN_CLOSED):
            break

    window.close()

mkWindow()

编辑以添加代码。我将其缩减为仅在生成 GUI 时仍会产生效果的受影响框架。

Answer 1

确实文档里都有。有一个 pin 函数可以完全满足我的需求。如果在任何类型的框架内添加，框架 auto-sizes 将如预期。我相信它确实会在折叠函数中稍微移动一些东西，因为它是一个更大布局中的布局元素，但我通过将其他元素放在另一个元素中来解决这个问题，这样它们就可以对齐了。希望这可以帮助那里的人。

import PySimpleGUI as sg

Demo - "Collapsible" sections of windows

This demo shows one techinique for creating a collapsible section (Column) within your window.

It uses the "pin" function so you'll need version 4.28.0+

A number of "shortcut aliases" are used in the layouts to compact things a bit.
In case you've not encountered these shortcuts, the meaning are:
B = Button, T = Text, I = Input = InputText, k = key
Also, both methods for specifying Button colors were used (tuple / single string)
Section #2 uses them the most to show you what it's like to use more compact names.

To open/close a section, click on the arrow or name of the section.
Section 2 can also be controlled using the checkbox at the top of the window just to
show that there are multiple way to trigger events such as these.
