Compose key support missing in QtWayland


    • Type: Bug
    • Status: Closed
    • Priority: P2: Important
    • Resolution: Done
    • Affects Version/s: 5.7.0, 5.9.3, 5.10

      Qt does not support compose key even if it's set in the keymap. This makes it impossible to e.g. input letters like ö, ä, ü, ß with an English keyboard. Those letters just were entered through the compose key on an Xwayland window.

      Steps to reproduce:
      1. Use a Wayland session (e.g. Plasma 5.7)
      2. Setup a keymap with compose key support (e.g. systemsettings -> Input Devices -> Keyboard -> Advanced -> select a "Position of compose key")
      3. Open a Qt application with --platform wayland
      4. Try to enter text with the compose key
      5. Open same application with --platform xcb
      6. Try to enter text with compose key

      Actual Result: input is wrong in case of Qt window
      Expected Result: same text entered whether it's xcb or wayland

      Please note that GTK+ on Wayland handles this correctly.
