PyQt6 support?

[Willy-JL]

I tried editing __init__.py mimicking PyQt5 , copy-pasting and changing to PyQt6 where relevant, but running the aiohttp example using PyQt6.QtWidgets ends up with this:

Traceback (most recent call last):
  File "/home/willyjl/.pyenv/versions/3.9.6/lib/python3.9/asyncio/selector_events.py", line 261, in _add_reader
    key = self._selector.get_key(fd)
  File "/home/willyjl/.pyenv/versions/3.9.6/lib/python3.9/selectors.py", line 193, in get_key
    raise KeyError("{!r} is not registered".format(fileobj)) from None
KeyError: '6 is not registered'

During handling of the above exception, another exception occurred:

Is PyQt6 support planned? Am I missing something?

[TheGreatCabbage]

PyQt6 isn't fully supported yet, sorry. Some changes were made for PyQt6 but it's incomplete. I can't really say when/if I'll have time to finish it.

[Willy-JL]

No worries, and thanks for even making this in the first place :D

[eyllanesc]

@Willy-JL I have created a PR #53 that supports PyQt6, hopefully it will be accepted soon.

Until my PR is accepted you could install my version through the command:

pip install git+https://github.com/eyllanesc/qasync.git@PyQt6

[sharpordie]

@eyllanesc
I have installed your version but I have this error with from __feature__ import snake_case.

AttributeError: '_SimpleTimer' object has no attribute 'startTimer'
ERROR:qasync._QEventLoop:Task was destroyed but it is pending!

[eyllanesc]

@sharpordie qasync does not support PySide6's snake_case feature, if you wish then you should create another issue pointing out your requirement more clearly.

[eyllanesc]

@TheGreatCabbage I think this issue should be closed.

[Willy-JL]

Ah, just saw the PR was merged. Thanks again mate!

Should README.md be updated to reflect this change? It specifically states "PyQt5 or PySide2".
