You can create a C++ method for this, expose it into a C++ singleton to easily access it:
Q_INVOKABLE QString MySingleton::idName(QObject * object) const { const auto context = qmlContext(object); return context ? context->nameForObject(object): QString("context not found"); } http://doc.qt.io/qt-5/qqmlcontext.html#nameForObject For Qml it return the context id. Other useful methods would be address and file where the object come from: Q_INVOKABLE QString MySingleton::objHexAddress(QObject * object) const { return QString().sprintf("%08p", object); } Q_INVOKABLE QUrl MySingleton::whereAmIDeclared(QObject * object) const { if (object) if (auto context = QQmlEngine::contextForObject(object)) return context->baseUrl(); return QUrl(); } This help a lot to debug into the console.
