Supporting non-QWERTY keyboards about userspace-tablet-driver-gui

[kurikaesu]

I've asked a question on stack-overflow to see if there is a proper way to do it here: https://stackoverflow.com/questions/69337117/linux-x11-getting-international-keyboard-key-from-scancode

Ok, definitely doesn't seem like we've missed anything obvious then since i run Ubuntu 20 on my development desktop.
I'll be out on holiday from tomorrow until the 6th of October so I won't really be able to troubleshoot much during the period. However when I get back I'll source a French keyboard and work on fixing the mapping issues.

[kurikaesu]

Great call out. Currently I am assuming the raw scan code to qwerty map like it is done in the kernel: https://github.com/torvalds/linux/blob/master/include/uapi/linux/input-event-codes.h#L91-L96

NativeKeyEvent.keyChar() translates the pressed keys to the actual layout keys but that only works during entry. When the configuration is loading, we aren't able to use the NativeKeyEvent functions to get the native unicode characters.

Likely need to work out how to query the keys from X11 and use the mapping directly there instead.

Could you pull in commit 8678e5d and see if that fixes the layout mapping for you?

I made the PRs, unfortunately the new commit does not seem to solve the problem: the keys still register as QWERTY entries... did it work on your JIS keyboard?

[kurikaesu]

Yeah on my JIS keyboard the keys like "@" show up correctly.
I may get a French keyboard to test with moving forward as having the shortcut keys localized is a good thing.

[Silmathoron]

OK, weird... is there a chance I need to rebuild from scratch or remove some previous files for it to work? Everything else worked even though I just reran build as I fixed previous issues so I did not try that...
But if you know French people who can lend you a keyboard I guess that's good too ^^

[kurikaesu]

Oh that's weird, are the keys all working now?
Every time I've made a change to the code it immediately picks up the changes.

[Silmathoron]

No sorry, I meant "I did not do that, could it be the problem?"
But I also don't think so, other changes were immediately picked up... or maybe are there other dependencies that the code introduced and that I may be missing?

[kurikaesu]

I don't think you've missed anything here. Which Linux distribution do you use?

[Silmathoron]

It's on my wife's computer which is a Pop!OS 21.04 so Ubuntu-based

I have ordered a French keyboard. I will hopefully receive it this week and get time to look into the mapping.

[kurikaesu]

French keyboard arrived today. Commit b5c9d3e should have fixed the layout for AZERTY keyboards.

It is not 100% fixed as if you are like me and have two non-us keyboards that you can switch between (In my case, JP and now FR) then I can't reliably check what is the currently active layout.

[Silmathoron]

Just checked and it works perfectly, thanks :)
As far as I'm concerned I think current keyboard support is good enough (what you mention really feels like an edge case) so feel free to close this issue

[kurikaesu]

Alright, thanks for confirming!
