Qt6 anki problem about ankirandomfont

[yaoberh]

Changing QFontDatabase().families() to QFontDatabase::families() as per qt6 changes returns this error:

When loading '⁨Randomize Fonts⁩':
⁨Traceback (most recent call last):
  File "/home/yaoberh/pyenv/lib/python3.10/site-packages/aqt/addons.py", line 239, in loadAddons

It looks like it's no longer necessary to instantiate a QFontDatabase object as of Qt6:
https://doc.qt.io/archives/qt-6.0/qfontdatabase-obsolete.html

Try QFontDatabase.families()

[yaoberh]

That seems to have solved that line, but now I'm getting an error in the next one:

    defaultFont = QFontDatabase().systemFont(QFontDatabase.GeneralFont).family()
TypeError: QFontDatabase(QFontDatabase): not enough arguments

[AustinHasten]

Looks like we'll also need to remove the parens on that same line. So:

QFontDatabase.systemFont(QFontDatabase.GeneralFont).family()

[AustinHasten]

Looks like WritingSystems used to be their own special class but now they're just python built-in enums. I don't have Anki Qt6 installed so I can't test myself, but I think we would need to update the line to be:

for font in QFontDatabase.WritingSystem[wsName];

[yaoberh]

Getting this error now :(

TypeError: 'WritingSystem' object is not iterable

[AustinHasten]

Oops, I think it might actually be

for font in QFontDatabase.families(QFontDatabase.WritingSystem[wsName]):

Thanks for testing this out and troubleshooting with me.

[yaoberh]

Error's jumping to another area now haha

[AustinHasten]

I think we just need parens after systemFont on that line.

TypeError: systemFont(QFontDatabase.SystemFont): not enough arguments

[AustinHasten]

I guess we need QFontDatabase.GeneralFont in the parenthesis after systemFont.

[yaoberh]

Yep! Anki starts with no errors now. Although it still throws this error in preview and Cards:

[AustinHasten]

That one has me a little stumped so I'll grab Anki qt6 and do some testing of my own

[AustinHasten]

init.zip

Not sure how this differs than what you have but this one is working for me.

Working! 👯
