python - 扩展布局添加的输入框的 PySimpleGui Rick Click Menu 剪贴板

Question

TL; DR：我基本上是想弄清楚如何从 PySimpleGui Github 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其中已动态创建传递给剪贴板函数的元素键...

使用 PySimpleGui 的文档以及关于 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，并且我已经为这方面的所有内容进行了排序（即使用添加元素到 GUI 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，我正在使用 Frame，并使用迭代器向其中添加 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，他们希望在其中放入一长串文本（在我的情况下为文件夹路径），因此需要“右键单击上下文菜单”，因此我想考虑添加它。

我的问题是 Multi-line Rick Click Menu Clipboard 演示需要将触发元素键传递给函数（然后用于向其中添加/删除文本），但是因为我为我需要的元素“动态生成”了键名在能够通过之前找出哪个元素键激活了右键菜单，我只是不知道该怎么做.....

我写的代码和 Layout_extend 演示基本相同.....

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 Python GUI 的唯一方法日期....

如果在现阶段无法做到这一点，那没关系，但至少我问过（当我不可避免地有人在使用它时说“我不能右键单击它真的很烦人”时，这让我感觉更好）！

一如既往地提前感谢！
