PySimpleGui Rick 单击菜单剪贴板，用于通过 extend_layout

如何解决PySimpleGui Rick 单击菜单剪贴板，用于通过 extend_layout

TL;DR：我基本上是想弄清楚如何从 PySimpleGui Github 中合并这两个示例代码：https://github.com/PySimpleGUI/PySimpleGUI/blob/master/DemoPrograms/Demo_Layout_Extend.py 和 https://github.com/PySimpleGUI/PySimpleGUI/blob/master/DemoPrograms/Demo_Multiline_Right_Click_Menu_Clipboard.py 其中传递给剪贴板函数的元素键已动态创建...

使用 PySimpleGui 的文档以及有关 stackoverflow 和 Github 演示的大量信息，我制作了一个“简单”的 gui，可以添加和删除输入字段，并且我已针对该方面的所有内容进行了排序（即添加元素到GUI 使用 layout_extend，使用 .hide_row() 删除元素并保留已删除值的列表等...

就像 layout_extend 演示一样，我使用了一个框架，并使用迭代器向其添加 GUI 元素以确保创建唯一的“键”。

##CODE SNIPPET AS MOST OF IT IS PRETTY MUCH THE SAME AS THE EXAMPLE DEMO CODE WITH MInor CHANGES

right_click_menu = ['',['copy','Paste','Select All','Cut']]

def do_clipboard_operation(event,window,element):
    #Same as Demo Code Here No Point copying!

...
...

if event in right_click_menu[1]:
    do_clipboard_operation(event,program_window,element)
if event == '-ADdpath-':
    program_window.extend_layout(program_window['-FRAME1-'],[[sg.Text('PATH:'),sg.Input(key=f'-PATH{i}-',rick_click_menu=right_click_menu),sg.Folderbrowse(initial_folder="/base/path",key=f'-broWSEPATH{i}-'),sg.Button('Remove Path',key=f'-REMOVEPATH{i}-')]])
    i += 1
...
...

当用户看到一个输入字段时，他们想在其中放置一长串文本（在我的情况下是文件夹路径），因此需要“右键单击上下文菜单”，因此我想考虑添加

我的问题是多行 Rick 单击菜单剪贴板演示需要传递给函数的触发元素键（然后用于添加/删除文本），但因为我有“动态生成”键名元素我需要确定哪个元素键激活了右键单击菜单才能传递它，我只是不知道该怎么做.....

我写的代码和 Layout_extend demo 基本一致.....

我很欣赏 PySimpleGui，尽管它很棒，但它可能并不是处理动态 GUI 的最佳工具，但由于我一直在为 OO 编程而苦苦挣扎，这几乎是我能够构建功能性图形的唯一方法迄今为止的 Python GUI....

如果在这个阶段这不可能，那没关系，但至少我问过（这让我感觉好多了，当我不可避免地听到有人说'它真的很烦人，我不能右键单击'时，他们使用它）！！

一如既往地提前致谢！！
