Unqualified Access

What happened?

A parent element was accessed without its id .

Why is this bad?

This makes the code harder to read and impedes performance.

范例

import QtQuick
Item {
    property int helloWorld
    Item {
        property int unqualifiedAccess: helloWorld + 1 // not ok: Unqualified access here.
    }
}

You can fix this warning by referring to the parent object by id . If the object currently has no id , you will need to add one first.

import QtQuick
Item {
    id: root
    property int helloWorld
    Item {
        property int unqualifiedAccess: root.helloWorld + 1 // ok: this access is qualified now!
    }
}
