Tutorials are the fastest way of finding out what KDE will do for you, and how to do it. Here is a list of currently available tutorials.
- KDE 4 Programming Tutorial
- You are interested in writing applications with KDE 4? Here you get at tutorial which leads you from the beginners stuff to the advanced techniques.
- Debugging your application
- Tips, tools and techniques to apply when debugging your KDE application
- Writing Unittests for Qt4 and KDE4 with QTestLib (Original link)
- Tutorial by Brad Hards that describes how to write unit tests using the QTestLib framework. It is presented as an example based tutorial, and is still under development.
- Using Qt Designer to build user interfaces
- How to create UI files with designer, and how to integrate them into a KDE program
- Semi-automatic ways to detect code errors
- Techniques you can use to detect errors in KDE code
Managing Configuration Data With KConfig
- Using KConfig XT
- Tutorial on how to efficiently use the KConfig XT framework.
File Access With KIO
- 101: Unicode
- An introduction to what Unicode is as well as how to handle Unicode data in KDE applications.
- 110: Writing Applications With Localization in Mind
- This tutorial covers what localization is, why it's important and how to ensure your application is ready to be localized. A must read for all application developers.
- 115: Avoiding Common Localization Pitfalls
- There are several common mistakes that prevent applications from being properly localized. Find out what they are and how to easily avoid them in this tutorial.
- 120: Building KDE's Localization Module
- Building and installing language support from KDE's localization (l10n) module is a good idea for those working on applications in the main KDE repository. Doing so will allow you to test your application in another language and spot problem areas. Learn how to do just that in this tutorial.
- 200: Incorporating i18n Into the Build System
- Once your application is ready to be localized, the next step is to ensure that translation files are built automatically and kept up to date. This tutorial covers the necessary CMakeFiles.txt additions as well the process of distributing the resulting message catalogs with your application.
- 210: Common i18n Challenges and Solutions
- This tutorial covers challenges that you may eventually run into such as translating handbooks and other data that exists outside of the source code, merging and handling obsolete .po files, deeling with freezes, coding in languages other than English and creating independent releases of or moving applications between KDE modules.
Components and Plugins
Application Automation and Scripting
- 101: Introduction to D-Bus
- A straight-forward introduction to the core concepts in D-Bus from an application developer's perspective, this tutorial covers what D-Bus is and how it can be used by applications.
- 201: Accessing D-Bus Interfaces
- A step-by-step guide to calling D-Bus methods and connecting to D-Bus signals using QtDBus.
- 211: Creating D-Bus Interfaces
- Learn how to expose functionality in your application by creating and using custom D-Bus interfaces. Covers generating the XML descriptions, instantiating interfaces at run time and setting up the build system with CMake.
- 300: D-Bus Autostart Services
- Turn your application into a D-Bus autostart service with this tutorial. This D-Bus feature will ensure that even when your application isn't running that D-Bus calls made to it will work by relying on the D-Bus daemon itself to start your app if and when needed.
- Creating Konqueror Service Menus
- This tutorial shows you how to create mimetype-specific actions in Konqueror's context menu (aka "servicemenus")
How To Integrate Kross Into Your Application
Search and Metadata
- Writing file analyzers
- File analyzers extract data from files to display in the file dialogs and file managers. The data gathered this way is also used to search for files. KDE4 allows the use of multiple analyzers per file type. This tutorial describes how you can write new analyzers.
- Introduction to Solid
- An introduction to using the Solid hardware discovery and interaction system in KDE applications.
Get Hot New Stuff
- Introduction to Get Hot New Stuff
- An introduction to the developer-friendly network update system that allows KDE applications to fetch new application data at runtime in a user friendly manner.
- KNewStuffSecure: a secure way to share resources
- Tutorial showing how to share resources in a secured way (KDE 3.4 and later).
Rapid Application Development
- KDE-Python tutorial
- A python version of Daniel's KDE tutorial by Boudewijn Rempt.
- KDE Ruby Korundum tutorial
