快速提示：附加属性类型

qmllint 将此警告类别拼写为“[Quick.attached-property-type] ”。

附加属性必须附加到继承自特定类型的对象上

发生了什么？

您在类型不正确的对象中实例化了一个附加属性。

这有什么问题？

该附加属性将无法正常工作。

示例

import QtQuick

Item {
    QtObject {
        LayoutMirroring.enabled: true
    }
}

要解决此警告，请将包含该属性的类型修改为继承警告消息中提到的类型：

import QtQuick

Item {
    Item {
        LayoutMirroring.enabled: true
    }
}
