EventLoopType and asynchrony

	class EventLoopType(Enum):
	DEFAULT = "asyncio"
	QT = "Qt"
	SYNC = "sync"

Can I use Python’s built-in async/await coroutines with the QT event loop?

[jamesdbrock]

The only documentation I can find about PySide6 asynchrony is very vague. What’s the best way to do coroutines in collagraph?

It's complicated: https://github.com/harvimt/quamash

Personally I think until Pyside6 supports it natively we won't really be able to do it in an elegant/efficient manner.

Your first link is the best you can do with Qt today. I guess you could try to generalize that AsyncHelper.
I can explain the technical details but there's a lot to unpack here.

[jamesdbrock]

What do you think about https://github.com/CabbageDevelopment/qasync ? It says that it is a successor to quamash.

I think it's not worth the added complexity and adding a dependency to this project. We can design something ourselves based on that AsyncHelper pattern you referenced which seems like it should perform similarly with a lot less complicated code.
