    Revision as of 09:10, 5 August 2016


    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 for KDE4. Older KDE versions are discussed at the bottom of this page.

    Basics of how to program with the KDE Frameworks

    Are you interested in writing applications with the KDE Frameworks? This tutorial series is aimed at those completely new to it.

    Hello World
    An introduction to the very basics of KDE Frameworks programming
    Creating the Main Window
    This tutorial shows you the magic of an application's most important thing: The main window.
    Using Actions
    How to add actions to the menus and toolbars. Based on the MainWindow tutorial.
    Physical Simulation
    How to perform a physical simulation: animation and diagram
    Saving and Loading
    Introduces the KIO library while adding loading and saving support to our application.
    Command line arguments
    Adds the ability to specify which file to open from the command line to our text editor.
    Common Programming Mistakes
    Various common mistakes made while developing Qt and KDE applications and how to avoid them.
    Session Management
    Make your application aware of X sessions
    Icons
    Deliver your application with icons that are automatically installed to the right places. Based on the Kaction Tutorial.
    Desktop File
    Let your application show up in the K menu and in application menus. Based on the Icons Tutorial.

    Managing Configuration Data With KConfig

    Introduction To KConfig
    An overview of the KConfig classes and how to use them in your application code
    Using KConfig XT
    Tutorial on how to efficiently use the KConfig XT framework.
    Updating KConfig Files
    Tutorial on how to write an update script to keep changes in your application's config file format in sync with the user's already existing config file

    Services: Applications and Plugins

    Introduction to the Services Framework
    An overview of the services framework in KDE and what it provides the application developer. Covers the system configuration cache (SyCoCa), the source data files and what the indexed information can be used for.
    Finding Services Using Trader Queries
    How to find services, such as plugins or mimetypes, that are indexed in the SyCoCa using Trader Query Syntax
    Creating and Loading Plugins Using KService
    Learn how to define custom plugin types, find installed plugins (including 3rd party plugins) and load them in an easy and portable fashion using KService.

    Localization

    See also Localization portal.

    Introduction To Unicode
    An introduction to what Unicode is as well as how to handle Unicode data in KDE applications.
    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.
    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.
    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.
    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.
    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, dealing with freezes, coding in languages other than English and creating independent releases of or moving applications between KDE modules.
    Semantic Markup of Messages
    To ensure consistent presentation and more meaningful representations of messages in applications, semantic markup can be applied to messages marked for translation using the KUIT system. This tutorial describes how this system works.
    Automated i18n Code Checking
    The Krazy code checker scans KDE's code and reports common i18n mistakes.
    Dealing with Language Changes
    This tutorial covers dealing with changing languages: How to add the function to change the language and then dynamically update the user interface when language has been changed.
    Understanding How Messages Appear to Translators
    An introduction to what context information is extracted (and what isn't) from source code for translators to see.


    Accessibility

    Accessibility Overview
    A list of accessibility tutorials and general information.
    Accessibility Checklist
    What to look for in your application to make it accessible for as many people as possible.
    Screen Reader
    This tutorial will explain some details about using screen readers with KDE applications.
    Text-To-Speech
    How to utilize Jovie text-to-speech service in your application.

    Application Automation and Scripting

    D-Bus
