It does this through embedding C++ code as a context property in QML rather than explicitly connecting signals and slots. When the program is started, the C++ part send a signal to QML, including a parameter. Interacting with QML Objects from C++ | Qt QML 5.9 Connecting to QML Signals. All QML signals are automatically available to C++, and can be connected to using QObject::connect() like any ordinary Qt C++ signal.
