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 }
}
