Qt Modeling Language (QML) is a hierarchical declarative language for user interface layout with a syntax similar to JavaScript Object Notation (JSON).
It can bind to C++ objects via Qt’s meta object system and also supports inline JavaScript. It’s much like HTML or XAML but without the XMLness.
Before we recommend the best free tutorials, here’s a special mention for a free book that will help.
Qt5 Cadaques by Jürgen Ryannel
Qt5 Cadaques provides you with a walkthrough of the different aspects of application development using Qt 5.12. It focuses on the new Qt Quick technology, but also provides necessary information about writing C++ back-ends and extension for Qt Quick.
1. QML Tutorial
This tutorial gives an introduction to QML, the language for Qt Quick UIs. It doesn’t cover everything; the emphasis is on teaching the key principles, and features are introduced as needed.
Through the different steps of this tutorial we will learn about QML basic types, we will create our own QML component with properties and signals, and we will create a simple animation with the help of states and transitions.
2. Extending QML by Qt
These tutorials show how a QML-based application can be combined with C++ code using the Qt QML module.
3. Integrating C++ with QML by Jeff Tranter
Qt makes it quite easy to expose C++ code to QML. This tutorial takes you through the basic steps.
4. Qt5 tutorial by Jan Bodnar
In this tutorial, you will learn the basics of GUI programming with Qt5 and C++. The Qt5 tutorial is suitable of beginners and intermediate programmers.
