QML context of dynamically generated items

Hello, I’m trying to figure out in which context dynamically generated items are being stored? Therefor let me explain my scenario. First I’ve registered two new QML types: qmlRegisterType<MyViewController>("uicontrollers", 1, 0, "ViewController"); qmlRegisterType<MyTabController>("uicontrollers", 1, 0, "TabController"); Then I used them in qml files: mainview.qml Rectangle {       Component     {         id: tab_factory         MyTab {}     }       TabView     {         id: a_tabview         //some code here ...     }       ViewController     {         id: view_controller         objectName: "myViewController"           onNewTab:         {             var tab_obj = tab_factory.createObject(a_tabview)             var a_tab = a_tabview.addTab(a_name, tab_obj)             a_tab.active = true         } } MyTab.qml Component {     id: the_tab       Rectangle {         id: tab_frame         border.width: 0           property string the_name: ""           SplitView         {             id: a_tab_split               // some items here ...         }           TabController         {             id: my_tab_controller             objectName: "myTabController"               Component.onCompleted:             {                 console.log(my_tab_controller)             }         }     } } Dynamic tab creation works fine from my C++ class. Therefor I use the function described below to find my ViewController and emit newTab signal. But when I try to find the created TabController in the QML context I get no results: uicontroller.h //***************************************************************************** //** Template FindMyQMLObjects //***************************************************************************** template<typename T> QList<T> FindQMLObjects(QString in_name) {     QList<T> ret;     QList<QObject*> root_obj_list = m_engine.rootObjects();       foreach(QObject* obj, root_obj_list)     {         qDebug() << "root_obj name: " << obj->objectName();         ret = obj->findChildren<T>(in_name, Qt::FindChildrenRecursively);         if (ret.size() > 0) break;     }     return ret; } Any idea where my QML objects are hiding? Thanks for your help. Best regards, Rainer
