QLineEdit in Qt6 not work with fcitx

[jronald]

Env

• Manjaro KDE
• Qt 6.2.0
• fcitx 4.2.9.8
• ~/.pam_environment

  GTK_IM_MODULE DEFAULT=fcitx
  QT_IM_MODULE  DEFAULT=fcitx
  XMODIFIERS    DEFAULT=\@im=fcitx
  

Reproduce

1. Create a new Qt project in Qt Creator
2. Edit CmakeLists.txt to use Qt5 or Qt6
3. Add a QLineEdit on the main windows
4. Build and run
5. Focus on the QLineEdit
6. Press Ctrl+Space

Problem

• Edit CmakeLists.txt to use Qt5, Ctrl+Space can be used to switch input mehtod and it works fine
• Edit CmakeLists.txt to use Qt6, Ctrl+Space does nothing

UPDATE

Fixed by swithing to fcitx5.

BTW, it crashes by accident and be solved by deleting ~/.config/fcitx5 and reconfiguring.

did you try a more recent version of fcitx ?

Not yet, it's said fcitx 4 is under maintance only now, I'll try fcitx 5

Thanks

Hi,

While it might be a regression between Qt 5 and Qt 6, did you try a more recent version of fcitx ?
