Connecting C++ slots to QML signals - Qt 5 Blueprints [Book] The separation of the user interface and backend allows us to connect C++ slots to the QML signals. Although it's possible to write processing functions in QML and manipulate interface items in C++, it violates the principle of the separation. Therefore, you may want to know how to connect a C++ slot to a QML signal at first.
How Qt Signals and Slots Work - Woboq
QML Signal and Handler Event System | Qt 4.8 When a signal is connected to a method, the method is automatically invoked whenever the signal is emitted. (In Qt terminology, the method is a slot that is connected to the signal; all methods defined in QML are created as Qt slots.) This enables a signal to be received by a method instead of a signal handler. Integrating C++ with QML | ICS The preceding simple example shows how easy it is to create a new QML component in C++ and expose properties, signals and slots. While much can be done with QML, C++ is still useful and typically, it will be used in conjunction with QML in any non-trivial application.
