Duplicated name
This warning category is spelled [duplicated-name] by qmllint.
Duplicated property, signal, or method name
What happened?
You gave a property, signal or method a name which is already in use in the current QML component.
Why is this bad?
The QML runtime doesn't create components with duplicate member names at runtime: they will be null instead.
Example
import QtQuick Item { property int helloWorld property int helloWorld // duplicate property signal helloWorld() // duplicate signal }
To fix this warning, remove or rename the duplicate members:
