Duplicate enum entries

This warning category is spelled [duplicate-enum-entries] by qmllint.

Enum key X has already been declared

What happened?

An enum contains two identical entries.

Why is that bad?

The same key is associated with multiple values. It isn't clear which one will be used.

Example

import QtQuick

Item {
    enum E { A = 0, B = 1, C = 2, A = 3 }
}

To fix this warning, remove or rename duplicate enum entries:

import QtQuick

Item {
    enum E { A = 0, B = 1, C = 2, D = 3 }
}
