继承循环

qmllint 将此警告类别拼写为[inheritance-cycle] 。

组件属于继承循环的一部分

发生了什么？

某个组件直接或间接地从自身继承。

通常，组件可以从其他组件继承属性、方法、信号和枚举。

如果一个组件直接或通过另一个基组件间接继承了自身，则会形成一个继承循环。该警告表明当前组件处于继承循环之中，请参见示例。

这有什么问题？

存在继承循环的组件在运行时不会被创建：它们将被视为 null。

示例

import QtQuick

Item {
    component Cycle: Cycle {} // not ok: directly inherits from itself
    component C: C2 {}        // not ok: indirectly inherits from itself
    component C2: C{}
}

要解决此警告，请打破继承循环：

import QtQuick

Item {
    component Cycle: Item {}  // ok: does not inherit from itself
    component C: C2 {}        // ok: does not indirectly inherits from itself anymore
    component C2: Cycle{}
}
