Blog - Qt Qml development

We continue our series of blog posts about integrating C++ and Qml. Last time we covered registering C++ types as singletons in Qml. Today we will proceed with another frequently used technique in Qt software development ― utilizing C++ enums in Qml code. In this article we continue using the most recent method of integrating C++ code and Qml ― CMake command qt_add_qml_module().

In our previous post about integrating C++ and Qml we have explained why it is important to integrate C++ and Qml and covered the basics of this mechanism. In this article we will go into more details and discuss a specific real-life example of integrating elements which can be instantiated one-time only (aka. singletons).

This tutorial about how to expose object and register C++ class to Qml is the first post in the new post series on Scythe Studio blog. The series is going to be entitled „How to integrate Qml and C++”. With the new Qt 6 version it’s not that clear how to properly and easily implement this crucial mechanism in Qt software development. Especially as many people currently move to CMake from qmake. Therefore, we thought that it would be a nice opportunity to explain various ways of Qml and C++ integration in details.
Future posts will cover mechanisms like models and plugins, but for now let’s focus on the basics and let’s explain how to access C++ object from Qml and how to register C++ class to Qml.
