Enhancement - Is there a preferred way to terminate a subprocess started with sg.execute_command_subprocess()? (add a terminate process call)

首先查看 issue 中提到的 execute_command_subprocess 入口点以及现有的 Call Reference 和 Cookbook 部分。记录终止异步启动的子进程所支持的方式，包括一个简短的使用示例和任何相关的资源注意事项；当指南能够清楚地回答这个问题时，工作就完成了。

Anything else you think would be helpful?

This issue is really a documentation and recommended coding style question_ Perhaps it could be cleared by just by an explicit answer and example in the Call Reference and Cookbook.

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

Hi Mike! Thank you for all you are doing for PySimpleGUI!!!_

I have a program which starts up several async processes using sg.execute_command_subprocess().

I have a PYsimpleGUI button, and when the user clicks that button, I want to terminate the subprocesses started earlier, which are still running asynchronously.

I looked through the call reference and cookbook but I did not see any corresponding sg.terminate_subprocess() function.

I was wondering if calling terminate on the object like this, rather than using a PySimpleGUI command (that I didn't find) would cause any problems with resource leaks or other problems within the PySimpleGUI object.

Code To Duplicate

Since sg.execute_command_subprocess() returns a popen_object, I can just send the terminate() message to the object like this:

import PySimpleGUI as sg

popen_object = sg.sg.execute_command_subprocess(
return_info  = popen_object.terminate()
print(return_info)

Watcha Makin?

I'm writing a program that extracts still images from video streams of multiple camera sources.
