未解析的别名
qmllint 将此警告类别拼写为“[unresolved-alias] ”。
未解析的别名
发生了什么？
属性别名应持有对另一个属性的引用，另请参阅《QML 对象属性——属性别名》。在此情况下，它持有对一个未找到的属性的引用。
为什么这有问题？
包含未解析别名的组件实例在运行时将无法创建：它们将被设为 null。
示例
import QtQuick
Item {
id: someId
property int helloWorld
property alias helloWorldAlias: helloWorld // not ok: aliases have to refer by id
property alias helloWorldAlias2: someId.helloWorlddd // not ok: no helloWorlddd in someId
property alias helloWorldAlias3: someIddd.helloWorld // not ok: someIddd does not exist
}要解决此警告，请确保别名属性中的 id 和 property 确实存在：
import QtQuick
Item {
id: someId
property int helloWorld
property alias helloWorldAlias: someId.helloWorld // ok: alias refers by id
property alias helloWorldAlias2: someId.helloWorld // ok: helloWorld does exist in someId
property alias helloWorldAlias3: someId.helloWorld // ok: someId does exist
