Plugin devs: Upcoming migration to Qt 6

[lomkiri]

I wiped the dir. and DL the file again (https://download.calibre-ebook.com/b...-5.99.7.tar.xz, (sha256: cba789af28dc4cd097755e16e63ae5b3fc0d98254f9be2a9e2 c08a035658fb0a, space inside sha is added by this bb-editor and must be deleted), resulting dir, unpacked, is 382,483,553 bytes, but I still get the same error.

I tried to DL (as a zip) the git-branch qt6, same version and same error (resulting dir is 48,872,261 bytes).
Options -w and -g of calibre-debug give me the same exception.
Anyway, I'll use the 5.99.7 binaries, so it's not a problem for me, as far as it's ok for you.

Just noticed the Comments column has lost its header ("Comments") in Book Details in 5.99.7 - not sure if it was like that in prior 5.99 releases. OK in 5.36. Without it there's no separation between custom HTML long text columns and Comments column.

The Comments header was added to Book Details display when Long Text columns were enhanced, and I don't think there should be two fields titled "Column heading" in long text definitions.

I think that somehow this preference was changed to "Never". Setting it to one of the other choices works for me.

Charles,
I noticed quite a few Look and Feel type tweaks, also got forgotten
(My field orders on the form, reverted to default positions. Might have happened earlier in the Beta)

What do you mean, "forgotten"? Some names would be useful. I didn't touch any tweak that didn't have a direct relationship with edit metadata.

As for the field order, as I said here I didn't migrate that one.

I need to read better. That explains it.
Sorry for the false report

- I never knew that setting existed, or more likely I'd forgotten it.

Maybe I shouldn't have. Yet on macOS Monterey 12.3 beta, launching calibre crashes:

That will most likely be the parasites at apple leaching of libxml2, they are a trillion dollar company and libxml2 is currently without a maintainer. Makes me extremely angry. They are linking various of their system frameworks against libxml2 these days and they use incompatible versions, causing endless headaches. It's a real shame libxml2 uses an MIT license instead of the GPL3. I'll look into sometime when I have a moment.

EDIT: https://github.com/kovidgoyal/calibr...a0bbe2305056f7 I was wrong its libexpat not libxml2 in this case

[democrite]

Thanks. Version 5 continues to work if that is any help regarding fix, if that or something else.

As of 5.99.3 the betas have support for proper icon themeing with support for using different icon themes for light and dark mode and calibre switches between them automatically. In order to use icons from themes that support your plugin you should pass the plugin name to the get_icons() function to load an icon. For example:

icon = get_icons('owp_sigil.png', 'Open With')

this will load the owp_sigil.png plugin from the users installed icon theme, if present, falling back to the image in the plugin zip file. Note that if you use kiwidude's code for loading icons, you will need to adjust it, as the way it loads themed icons will no longer work.

Hi @kovidgoyal.

Where is located the theme folder now? I can't find it.
It's not on '/config_dir/resources/images' anymore.

Windows 10 Pro x64 21H2
calibre beta 5.99.7

There's no folder anymore icons are loaded from Qt resource files. You can still override individual icons using resources/images, but the actual themes are in compiled Qt resource files.

Thanks. I managed to access them with QIcon.ic('debug.png').

Released 5.99.8 with fixes for running under non Debian based linux distros and the upcoming macOS Monterey 12.3 (I hope, havent actually tested this)

[democrite]

No problems with macOS 12.3 so far. Thanks.
