When using application manager to launch the out-of-process application with TextField, the property text is not set when the field loses focus.

The issue can be reproduced on yocto imx8 linux with Qt 6.8.3 using application manager to launch the out-of-process application where virtual keyboard is in the system-ui and it’s set to simple Chinese. When using mouse event over vnc, the code works correctly.

The following code is used in the out-of-process application:

TextField {
    id: root
    onFocusChanged: {
        if (!root.focus && root.preeditText !== "") {
            Qt.inputMethod.commit()
        }
    }
}

Once the TextField loses focus, the predict text is displayed over the text, but the property text is not used.

As a workaround, instead of calling Qt.inputMethod.commit() the text can be set with:

root.text = root.preeditText
