* Alias PyQt5 to PyQt6 on PyQt6 builds
Restores basic compatibility with PyQt5 add-ons
* Register QtCore early to work around sip error
* Monkey-patch unscoped enums that are in use by add-ons back in
Enums whose namespace moved with PyQt6 were determined using the tooling in https://github.com/qutebrowser/qutebrowser/issues/5904
Relevant enums for the Anki add-on ecosystem were found by grepping through all AnkiWeb add-ons and a selection of GitHub-released add-ons.
* Add full Qt.Key namespace
Maintains compatibility with add-ons that allow specifying key bindings via Qt.Key enums
* Reintroduce PyQt6.Qt as an alias for QtCore.Qt
* Alias classes shifted from QtWidgets to QtGui
* Add missing enums
Adds ≈200 enums that were missed during the initial grep
* Map exec_ calls to exec
* Tweak section headers
* Fix QtWebEngineWidgets imports failing due to delayed import
Addesses: "QtWebEngineWidgets must be imported before a QCoreApplication instance is created"
* Register additional aliases for top-level Qt modules
Given how we have had to deal with side-effects when not registering other aliased imports ahead of time, it seems safer to also register the remaining few with sys.modules.
* Handle calls to deprecated PyQt resource API graciously
* Create QtWebEngineWidgets aliases for classes moved to QtWebEngineCore
* Alias QShortcut
* Restore QWebEnginePage.view()
* Alias sip to PyQt6.sip
* Alias QtCore.QRegExp to QtCore.QRegularExpression
* Restructure aqt.qt into package
Pre-requirement for aliasing the PyQt5.Qt namespace correctly.
Should hopefully also make it easier to keep an overview as Qt-compat-related modules were proliferating.
* Properly alias PyQt5.Qt
PyQt5.Qt used to serve as a common namespace for all Qt classes, not just QtCore.Qt.*
While this changes does not make all classes accessible via PyQt5.Qt, it does so for the most important Qt submodules, which should cover most add-on breakages.
* Simplify Qt resource system legacy handling
* Also alias PyQt6.Qt
Covers imports of the form `from PyQt5 import import Qt` (due to previous aliasing of PyQt5 to PyQt6)
* Add missing enums
Better approach to grepping through add-ons yielded additional hits
* Run formatters
* Satisfy pylint
The enum changes should work on PyQt 5.x, and are required in PyQt 6.x.
They are not supported by the PyQt5 typings however, so we need to run
our tests with PyQt6.
The type hints allow mypy to check the gui_hook calls, revealing a
bunch of places that are broken as they expect no arguments like the
legacy hooks.
To make mypy happy about PyQt's signal.connect(func), a qconnect()
helper has been added.
