Qt NextItemFocusChain函数在mac上的qml中不工作？

我有一个表单，其中我做了一个自定义字段，它只接受顶部、右侧和底部箭头

但要接受选项卡导航，我将使用以下功能链：

nextItemInFocusChain（）.forceActiveFocus（）

问题是，这在

windows

上起作用，但在

mac上不起作用

我有一个公式集来说明问题，在“代码文本字段”旁边，我有一个
组合框
，当用户单击“代码文本字段”中的
选项卡
进行导航时

它似乎只导航到其他
textFields
，而一个
spinBox
，就像我在示例中所做的那样，似乎有一个
textField
作为
contentItem

main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>

int main(int argc, char *argv[])
{
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

    QGuiApplication app(argc, argv);

    QQmlApplicationEngine engine;
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
    if (engine.rootObjects().isEmpty())
        return -1;

    return app.exec();
}

我是否对mac os x做了一些错误的操作，或者是否有解决方法？
打开
系统首选项>键盘>快捷键
，然后选择
所有控件
。默认情况下，macOS仅允许在“仅文本框和列表”之间进行选项卡导航

我明白了，但有没有办法绕过操作系统的限制？我不知道。
