Running an IME with Qt Widget

Question

I can't get an IME to work with a Qt Widget (the goal is to write Japanese characters with a western keyboard). I can't activate the IME in the taskbar when I launch a simple test software (a QLineEdit in a QMainWidow).

I set the Qt::WA_InputMethodEnabled to true for the QLineEdit widget only, then also for the QMainWindow. This has no effect.

The IME works fine with a text editor like Xed.

I'm using:

• Linux Mint 21.1
• Qt Creator 11.02
• Qt 6.4.0

What can I do?

Answer 1

Qt5

The file libfcitxplatforminputcontextplugin.so is required in the directory:

[...]/Qt/5.xxx.xxx/gcc_64/plugins/platforminputcontexts
