Question

我的qt快速应用程序中有一个自定义对话框，当我点击一个按钮打开它时，我会得到以下错误：

QQuickItem :: stackBefore：无法在0x6d4bd6e220之前堆叠，这必须是兄弟

发生此错误后，main.qml页面上的所有qml项目都将禁用并且不起作用，并且不会与宽度鼠标进行交互。

main.qml

onClicked: {     
                var c= userPorfileCom.createObject(mainWindow);
                 c.open();
            }

Component{
    id:userPorfileCom
    UserProfilePage{
        id: userProfilePage
    }
}

UserProfilePage.qml

如果标签焦点链中有两个项目，而不是兄弟姐妹则不会工作，意味着标签焦点链中的内容必须具有相同的直接父级。
