Detecting changes to the quickfix list

[Sylvia]

Hello everyone,

I'm writing a script that needs to trigger an action when the quickfix list changes.

After reading the docs, I tried using something like this:

autocmd QuickFixCmdPost * call MyFunction()

This works for most quickfix manipulation commands, like `cexpr`, but fails for `setqflist`. Indeed, the docs don't mention `setqflist` as one of the functions that trigger this event.

Is there any way I can detect every change to the quickfix, no matter which function was used to do it?
