    Building an Existing KDE Application

    If you want to improve an existing application, you can usually build and install it easily. This tutorial shows how to build an application in a way that doesn't interfere with your system. If you do not need to modify kdelibs this may be the easiest way to get started with development.

    Debugging your application
    Tips, tools and techniques to apply when debugging your KDE application
    Writing Unittests for Qt4 and KDE4 with QTestLib (Original link)

    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.
