Enum declared outside the root element

This warning category is spelled [non-root-enum] by qmllint.

Enum declared outside the root element

What happened?

An enum was declared outside of the root element of the component.

Why is that bad?

It won't be accessible. Enums are accessed as <component name>.<optional enum name>.<enum entry>. If the enum is not at the root of the component, this lookup won't work.

Example

// Main.qml
import QtQuick

Item {
    Item {
        id: item
        enum Color { Red, Green, Blue }
    }
}

To fix this warning, move the enum to the root of the component:

// Main.qml
import QtQuick

Item {
    enum Color { Red, Green, Blue } // Accessible in Main.qml but also from other files
    Item {
        id: item
    }
}
