Description ratijas 2021-09-27 17:01:01 UTC 
SUMMARY
Internal error in "QtQuick/Controls.2/org.kde.desktop".

Root QML type of TextFieldContextMenu.qml is QtQuick.Controls.2/Menu, and I have no idea where i18nc is supposed to be pulled from.

STEPS TO REPRODUCE
1. Create a stub application in Qt Creator.
2. Add QuickControls2 to Qt, and `find_package(KF5Kirigami2 2.7.0)`.
3. `Import org.kde.kirigami 2.4 as Kirigami` in your main.qml.
4. Declare a QQC2/TextField item.
5. Build & Run.
6. Click on a text field to give it a focus.

ADDITIONAL INFORMATION
Comment 1 ratijas 2023-06-13 23:01:29 UTC 
The i18n() function (as well as many others in that family) comes from a context object KLocalizationContext from KF::I18n package. This object should be initialized and set to QML engine in C++ code, there's currently no way around doing that. QQC2 Desktop Style, by not being a Tier 1 framework, can expect that i18n stuff will be set up by any calling code. On the other hand, for example Kirigami is a Tier 1 framework which can not depend on KI18n, so can only use simpler qsTr() functions in its components.

So, to sum up: these reference errors are not bugs in org.kde.desktop but an issue with me using a runtime without expected context object. To solve this problem I created `kqml` — QML runtime with initialized KLocalizedContext. Read more: https://invent.kde.org/plasma/plasma-sdk/-/merge_requests/79
