Description Tyson Tan 2018-06-19 07:21:07 UTC
Created attachment 113419 [details] New tag box location Premise: Chinese, Japanese and Korean have way too many letters. Unlike western languages which can be input directly from a keyboard, CJK languages are typically input using a helper application that translates latin-formatted pronunciation into actual letters: INPUT [HUI HUA] >> OUTPUT [绘画] (Chinese word for drawing). On Linux, we call these helpers "Input sources", and we generally have two choices for Input Source Framework: ibus (GNOME) or fcitx (KDE) and scim. These are the base services for loading different input schemes like: ibus-libpinyin, fcitx-libpinyin. On Windows, these are handled as the Input Methods (IMEs). The Bug itself: CJK input method cannot be used in Brush Preset Docker's New tag input box. It can be used in the docker's Search box, but not in the right-click menu's "New tag" box. When the cursor is in the Search box, I can trigger input method with Shift/Super+Space. But for some reason, I can neither trigger them in the "new tag" box. Even when I enter the new tag box with my input method turned-on, it can only input English. This bug happens on both Linux and Windows, and the symptoms are 100% identical. I suspect it to be a deficiency from Qt. Workaround: Copy and paste existing CJK letters directly into "New tag" box.
Comment 1 Halla Rempt 2018-06-19 07:26:45 UTC
Maybe that's because this is in a popup, and the input thing is also a popup?
Comment 2 Tyson Tan 2018-06-19 07:39:19 UTC
Created attachment 113420 [details] Input method at work in Brush Preset Docker's Search box Yeah, I think an input method can be counted as a on-canvas "popup".

Comment 5 Eike Hein 2018-06-21 10:38:40 UTC
I have an automatic daily Bugzilla search set up for "Korean" because I tend to work on text input issues across KDE (I live in Seoul and type Korean frequently). I am super busy currently, but I'll try to take a look at this soon.

Oh wait, this is Windows-specific? Then I might not be able to help, I only know Linux well :(.

(In reply to Eike Hein from comment #6) > Oh wait, this is Windows-specific? Then I might not be able to help, I only > know Linux well :(. Yes you can help, they are NOT exactly Windows specific. This one is Linux / Windows shared: https://bugs.kde.org/attachment.cgi?id=113419 Although tagged as Windows only, both Linux/Windows cannot switch input method in these boxes, although on Linux, I can switch to an input method before opening the popup and I can use it, while on Windows I cannot: https://bugs.kde.org/attachment.cgi?id=113476 https://bugs.kde.org/attachment.cgi?id=113477 I suspect a Qt issue here.

(In reply to Boudewijn Rempt from comment #8) > Maybe this is a duplicate https://bugs.kde.org/show_bug.cgi?id=395745 ? Probably not. I cannot recreate the same situation with either Linux's or Windows's Chinese input source. I guess it was that bug is specific to a Korean input source.
Comment 10 Tyson Tan 2018-10-15 02:02:44 UTC
Re-tested and Summary: ------------ ### Linux # Brush Preset Search box [Y] Input source can be switched [Y] Input source can be used # New Tag box [N] Input source can be switched [Y] Input source can be used ------------ ### Windows # Brush Preset Search box [Y] Input source can be switched [Y] Input source can be used # New Tag box [N] Input source can be switched [N] Input source can be used ------------ ### NOTES # Input source is toggled by: [Super] + [Space] # Input source's EN only mode is toggled by: [Shift] # Input source intercepts all keyboard inputs, but only in *SOME* input fields where it considers to be text input. For example, it doesn't work in password field. # My guess: It's either OS/DE or Krita is suppressing [Super] and [Shift] in some case; Or It's the input field of New Tag box not being recognized by Input Sources correctly.
Comment 11 Halla Rempt 2021-03-25 14:40:15 UTC
Windragon just checked this, and it's still an issue -- and I still don't know what to do other than to change the tagging menu into a tagging dialog. That should do the trick...

Comment 13 Alvin Wong 2021-05-29 12:45:18 UTC
@Tyson I think this commit fixes the issue, at least for me on Windows, without any adverse effects. Can you give it a test on both Windows and Linux with your input methods when it gets included in the upcoming nightly build?

I will test it as soon as it's in the nightly and provide my feedback here.
Comment 15 Tyson Tan 2021-05-31 03:33:55 UTC
Hi Alvin, I have tested both the Windows and Linux Nightlies: krita-nightly-x64-5.0.0-prealpha-30754f5f40-setup.exe krita-5.0.0-prealpha-30754f5-x86_64.appimage But unfortunately, neither of them worked for me. I will mark this as reopened.

Created attachment 138887 [details] The popup location where input method doesn't work To make sure we were on the same page, here is the screenshot of the popup location related to this bug.
Comment 17 Tyson Tan 2021-05-31 03:43:02 UTC
I used fcitx under Linux, and Windows 10 (20H2/21H1)'s system input method (not 3rd party) during the testing. I could use them in all other Krita input boxes except the tag popup. When the cursor was focused on that popup with Input Method already enabled, it will immediately cease to keep its state and fallback to System Base Keyboard (English).
Comment 18 Alvin Wong 2021-05-31 07:17:55 UTC
True, there are more popups with this behaviour. Maybe I should look into fixing it properly from within Qt instead?... I can try applying the same fix from Krita for them. Did you notice any more popups with this issue?
Comment 19 Tyson Tan 2021-05-31 07:32:40 UTC
So far the popup in Comment 16 is the only one I know that still not working. You have fixed every other similar input boxes that I know of (if they were broken). Sorry I have only checked that one because it was why I reported this bug. I totally forgot we have other popups like this.

Please let me know if it doesn't work, or if you find more popups with the same issue.

Created attachment 138924 [details] F5/F6 panel search box cannot switch input method after popup box switched Hi Alvin, Thank you for the last fix! Now the popups can switch input method. However, with that fix a new glitch has occurred: In F5/F6 panels, if I switched input method in a popup first, then I won't be able to switch input method in the search box. This issue doesn't affect Docker panels. The Docker panel's popup and search box remember their input method states individually. Workaround: Close and reopen the F5/F6 panel.

I think this might be specific to Linux (or even specific DEs) because I can't seem to reproduce this on Windows. I can try fixing this later on master, but it will not be in the next 4.4 release.

No problem, Krita 4.4 doesn't support non-latin1 characters for tags anyway -- they disappear upon restarting Krita. And I was unable to reproduce the last glitch on Windows either. As long as the Windows version works, this doesn't need to be a priority. The Android version could be affected though. So it would be nice if we can get to the bottom of this before Krita 5.0 is out.
Comment 27 Alvin Wong 2021-06-07 09:35:46 UTC
Sorry, I can't think of a reasonable method to fix the last issue without potentially breaking other things. I guess users will have to reopen the popup to fix it. I also tried to test it on Android, but my test system does not have a functional input method that supports a physical keyboard. It works with the on-screen keyboard though. It looks like the inability to use input methods in popups is "by design" (see ), so I suppose it is accidental that my workaround even works at all. : https://bugreports.qt.io/browse/QTBUG-83490

It's not news to me that the limitations from libraries or even computer languages can make certain features unfeasible or impractical. CJK Input methods themselves are already a hack of some sort. At least you made it work for Windows and Android, and the glitch under Linux has easy and natural workaround. Thank you again for your effort! :D

The local community reported two more location where input method cannot be used. They affect only the Windows version. See Comment 29 and Comment 30 for screenshots. I'm using Linux so I wasn't able to find them last time, sorry.

For the second new issue I opened bug 438122 because that needs another approach at fixing.
