As we’ve already seen in the previous examples, properties, signals and slots offer different types of communication between C++ and QML: Slots allow communication from QML to C++: Slots are used to trigger C++ code from QML. You can use parameters and return values to pass data to and from C++.

Connect Qt QML and C++ Overview. This program demonstrates how QML and C++ can be connected through Qt signals and slots. 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.
Connecting a Qt Quick Controls signal to a C++ slot | Qt Forum Instead of connecting a QML signal to a c++ slot I usually just call the c++ slot from c++ (without any connections), that of course depends on your c++ file but you can easily register any QObject with the QML engine and then create objects of the class form QML and also call slots and any function marked with Q_INVOKEABLE. Signals & Slots | Qt Core 5.12.3 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type. How Qt Signals and Slots Work - Woboq Qt is well known for its signals and slots mechanism. But how does it work? In this blog post, we will explore the internals of QObject and QMetaObject and discover how signals and slot work under the hood. In this blog article, I show portions of Qt5 code, sometimes edited for formatting and brevity.
Hi @LeeK, you can do one thing, you can connect the "SendMsgtoQml_ChangeScreen()" signal to a slot and in that slot you can call your QML function which is in your case "onChangeScreenQml" For example:-

We need an instance of HandleTextField, and the QML Window object. Then we can connect the windows submitTextField signal to the handleSubmitTextField slot. Running the application now and you should get a debug message showing the text being passed to C++.

Connecting C++ slots to QML signals - Qt 5 Blueprints 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.
