This tutorial will guide you through the process of creating your own convergent application using the Kirigami framework. A convergent application, in this context, means people can use the program easily regardless of the device it is running on. If it is on a desktop computer, it will adapt to a large screen and a mouse and keyboard; if it is being used on a mobile, it will accept input from a touchscreen and adapt to a smaller portrait screen. And so on.
Kirigami is built on top of the QML language and Qt Quick Controls 2 components provided by the Qt project. QML has built in support for touch systems, which makes it ideal for mobile apps. Qt Quick components are reusable visual items we can use when building our applications’ interfaces. Kirigami is a set of Qt Quick components designed for creating convergent applications.
While you will use QML to create the visual part of your application, the business logic – the code that does the heavy lifting for your application’s functionality – is usually created in C++ for performance reasons. We will also explore how to integrate our business logic with our UI in the tutorials below.
