This is similar to C/C++ function pointers, but Dynamic language tricks in C++, using Qt - EPx Signals and slots: implementation. After having worked with languages like Python and Objective C, it is kind of instinctive to search for dynamic features in Qt, to the point that it feels impossible to do something with bare C++ (without Qt Core at least).
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. In return, any C++ signal can be received by a QML object using signal handlers. Here is a QML component with a signal named qmlSignal that is
