Bug description

Cannot use Meta key in shortcuts.

Steps to reproduce
Steps to reproduce the behavior:

1. Go to Settings - Shortcuts.

3. Garbage in Key sequence field (rៀ?, Meta+Q), shortcut doesn't work.

Expected behavior

Shortcuts with Meta key worked before.

Screenshots

Environment

• OS: Exherbo Linux
• Desktop environment: none
• Crow Translate version: any recent

Additional context

Suspicion fell on newer qhotkey first, but I wasn't able to locate broken commit. Further investigation shows that this works with Qt 5.12.7, but not with current 5.14.1.

Confirmed! But, unfortunately, this is a regression in Qt, which is not related to Crow Translate :(

Workaround: open ~/.config/crow/Crow Translate.conf and manually replace ៀ?, Meta+E with Meta+E.

I see, thank you. My workaround would be to keep Qt 5.12 for a while.

Strange thing that shortcuts with Meta key works in other KDE apps, eg in Settings, here is a screencast:

It's because the bug in QKeySequenceEdit. KDE use their custom widget for it.

It's 2022 already, and this bug is still unresolved. Maybe we need to create our own widget based on QKeySequenceEdit? I don't think Qt will interested in resolving this bug in Qt 5, since they ditched LTS releases and Qt 6 will be a primary release now.

[Shatur]

I planning to migrate to Qt6 in the future :)

with the release of the new KDE plasma 6 it is a good idea to proceed to the Crow Translate upgrade

@Cherkah
None of the "stable" distributions are using KDE Plasma 6 at the moment.
