A few issue with 6.2.0

[Damien Elmes]

One other issue I forgot to mention - QByteArray can't be pickled on Python
10:

>>> from PyQt6.QtCore import QByteArray
>>> import pickle
>>> pickle.dumps(QByteArray(b"test"))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
SystemError: PY_SSIZE_T_CLEAN macro must be defined for '#' formats

Sorry, that should have read _arm64 above.

Workaround for now is to specify the older arch:

./venv2/bin/pip install pyqt6-qt6 pyqt6-webengine-qt6
--platform=macosx_10_14_arm64 --only-binary=:all: --no-deps --target
venv2/ext

I misspoke - the issue is arm64-specific - on arm64, unsigned code won't
run at all, so XCode will automatically
give outputs an 'ad-hoc' signature when they are created:

dae at armmini ~ % codesign -dvv
venv2/ext/PyQt6/Qt6/lib/QtWebEngineCore.framework/Versions/A/QtWebEngineCore
Executable=/Users/dae/venv2/ext/PyQt6/Qt6/lib/QtWebEngineCore.framework/Versions/A/QtWebEngineCore

CodeDirectory v=20400 size=1122728 flags=0x20002(adhoc,linker-signed)
hashes=35082+0 location=embedded
Signature=adhoc
[...]
dae at armmini ~ % codesign -vv
venv2/ext/PyQt6/Qt6/lib/QtWebEngineCore.framework/Versions/A/QtWebEngineCore

valid on disk
venv2/ext/PyQt6/Qt6/lib/QtWebEngineCore.framework/Versions/A/QtWebEngineCore:

The helper has an ad-hoc signature too, but it's malformed:

dae at armmini ~ % codesign -vv
venv2/ext/PyQt6/Qt6/lib/QtWebEngineCore.framework/Helpers/QtWebEngineProcess.app/Contents/MacOS/QtWebEngineProcess
venv2/ext/PyQt6/Qt6/lib/QtWebEngineCore.framework/Helpers/QtWebEngineProcess.app/Contents/MacOS/QtWebEngineProcess:
invalid signature (code or signature have been modified)

Sorry, I mistakenly lumped this one in with the other one, but it was a
different
issue that was not PyQt's fault (QComboBox::AdjustToMinimumContentsLength
needed to be changed to QComboBox::AdjustToMinimumContentsLengthWithIcon
in the UI file)

I thought I checked this after updating to PyQt6, but I can't reproduce the
issue now.

Here's a few:

        self.buttonBox.accepted.connect(ChangeMap.accept)  # type: ignore
        self.fields.doubleClicked['QModelIndex'].connect(ChangeMap.accept)
 # type: ignore

self.activeCheck.toggled['bool'].connect(self.activeList.setEnabled)  #
type: ignore

Without them, we get errors like:

aqt/forms/taglimit_qt6.py:54: error: "Callable[[], None]" has no attribute
"connect"  [attr-defined]
aqt/forms/taglimit_qt6.py:55: error: Value of type "Callable[[bool], None]"
is not indexable  [index]

Cheers,
Damien
