ID 与 shadows 成员

qmllint 将此警告类别拼写为[id-shadows-member] 。

ID 遮蔽了属性、方法或信号

发生了什么？

某个标识符可能在同一上下文中遮蔽了某个属性、方法或信号。

这有什么问题？

您将无法再通过其未限定名称访问该属性、方法或信号。原先这样操作的代码将转而默默访问该 id，这可能会导致难以发现的错误。

示例

import QtQuick

Item {
    Item { id: helloWorld }
    property int helloWorld: 42
    Component.onCompleted: console.log(helloWorld) // not 42
}

要解决此警告，请重命名该标识符或被遮蔽的成员。

import QtQuick

Item {
    Item { id: helloWorldId }
    property int helloWorld: 42
    Component.onCompleted: console.log(helloWorld) // now 42
}
