What to do after finishing your first simple Kirigami application
Last updated
Over the past few tutorials you have built a basic but functional Kirigami application that lets you add, edit, and delete date countdowns. In doing so we have learned about Kirigami and QtQuick components, some of how QML works, basic application layouts, and more. Not bad at all!
You now have a grasp of the basics that make up many of KDE's most popular applications. You might be asking yourself: what now?
Well, don't worry: we have taken the time to provide some pointers as to where you can go from here.
One of the best ways to improve your development skills is by putting them into practice. KDE's community is welcoming and always looking for more passionate developers!
We have several pieces of documentation that can help guide you towards becoming a contributor. We recommend you take a look at the developer-specific section of our which can help you learn more about the KDE Community's development workflow. We also recommend you take a look at our documentation for KDE's GitLab instance, called , as you will likely need to interact with it during the development process. The KDE Community interacts mainly through Matrix, and we also have that will guide you through setting up with your very own account.
With your newfound skills you are in a good position to begin contributing to Kirigami projects. Thankfully, many of KDE's most popular applications and components are built with this framework. Here are a list of projects you are welcome to help with.
A touch friendly calendar application designed for mobile devices.
An image viewer designed for desktop and touch devices.
A color contrast checker that tells you if your color combinations are accessible for people with color vision deficiencies.
An app to help you choose the license to go with your project.
A welcome app for the Plasma desktop that lets you create new pages with QML.
An application that helps you find and install applications, games, and tools.
A music player that strives to be simple and nice to use.
A multi-platform app that allows your devices to communicate (eg: your phone and your computer).
A companion application for conference attendees.
A client for Matrix, the decentralized communication protocol for instant messaging.
Not feeling quite ready yet? That's okay too.
Many of the projects listed above are invaluable learning resources. You can poke through the code and see how experienced developers have created fully-featured applications, and use these techniques yourself.
If you feel you need a more gentle approach, we have also compiled some resources we think you might find useful.
While we have learned a lot about QML, we haven't really touched upon how to handle backend code all that much. This is, however, an essential facet of KDE application development.
C++/Qt with Kirigami
In the advanced section of this Kirigami documentation we have some pages that can help you get started:
Learn all about CMake and how to compile your applications.
Getting to grips with the central C++ file that handles your application's initialisation.
Add advanced functionality to your Kirigami application and connect it to your UI.
Add an "About Page" to your UI.
Beginner C++ resources
If you are completely new to C++, there are numerous resources available throughout the web. Here are some that may be useful.
A comprehensive wikibook with C++ lessons and exercises
A set of C++ tutorials and other resources aimed at beginners
Tutorials to get to grips with C++
A reference site for C++
If you'd like to work on KDE applications such as Dolphin, Kontact, or Kate, you will need to learn how to use QtWidgets, which uses a completely different way of developing user interfaces with Qt. More complex KDE applications or applications that follow a traditional design tend to be built with QtWidgets.
The Qt project is extensive, and so are QML and QtQuick. There is a lot of functionality we haven't covered, but there is a lot of documentation we can pull from to find out more.
This documentation includes a lot more about Kirigami. You can poke through some of the Components pages to find out more about some of the QML components that Kirigami provides for you to use.
Don't be intimidated by all the material on here! No one starts off being able to create something like Plasma from scratch. But KDE is no multi-billion dollar company with a high barrier for entry (we have no five-round coding interviews!) and as long as you are nice, you will be welcomed.
Good luck!

We also provide a list of continuously updated resources to learn C++ in .
QtWidgets is somewhat more daunting to work with than QML (and much more C++ intensive!). Luckily, we have in the KDE Docs that will help you become more familiar with them.
If you want to look up what specific components do, look no further than
If you are looking for a more guided approach to learning, is a great place to start.
We recommend you also take a look at , an application designed by KDE developers to demonstrate Kirigami's tools and capabilities. It provides both interactive examples of Kirigami components as well as links to the source code of these examples so you can see how they were built.
