Development/Tutorials

Tutoriais são a maneira mais rápida de encontrar o que o KDE pode oferecer à você, e como fazê-lo. Abaixo encontra-se uma lista dos tutoriais atualmente disponíveis para KDE4. Material para KDE3 e KDE2 está disponível no final da página.

Introdução à programação para KDE 4

Você está interessado em escrever aplicações para KDE 4? Esta séria de tutoriais é completamente voltada a nova programação para o KDE.

Hello World: Uma introdução premilinar aos princípios da programação do KDE4

Criando a janela principal: Este tutorial mostra à você a mágica da coisa mais importante de uma aplicação: a janela principal, ou "main window".

Usando KActions: Como adicionar ações aos menus e barra de ferramentas.

Princípios

Migrando sua aplicação: Ajuda migrando aplicações do Qt3/KDE3 para Qt4/KDE4

Introdução ao CMake: Como usar o sistema de contrução CMake usado pelo KDE4.

Erros comuns de programação: Vários erros comuns cometidos durante o desenvolvimento de aplicações Qt e KDE e como evitá-los.

Usando Qt Designer para construir interfaces de usuário: Como criar arquivos UI com designer, e como integrá-los em um programa KDE.

Usando as opções da linha de comando: Processing and accessing command-line arguments the easy way with KDE's command line arguments classes.

Testando e Depurando

Depurando sua aplicação: Dicas, ferramentas e técnicas para usar enquanto depura sua aplicação KDE.

Escrevendo Unittests para Qt4 e KDE4 com QTestLib (Original link): Tutorial por Brad Hards que explica como escrever testes de unidade usando o framework QTestLib. Ele é apresentado como um exemplo que deu base ao tutorial, e está ainda em desenvolvimento.

Maneiras semi-automáticas de detectar erros no código: Técnicas que você pode usar para detectar erros no código KDE.

Gerenciando dados de configuração com KConfig

Introdução ao KConfig: Uma visão geral das classes KConfig e como usá-las no código da sua aplicação.

Usando KConfig XT: Tutorial de como usar de forma eficiente o framework KConfig XT.

Atualizando arquivos do KConfig: Tutorial de como escrever um script de atualização que mantém as mudanças no arquivo de configuração da sua aplicação sincronizadas com arquivo de configuração já existente do usuário

Serviços: Aplicações e 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

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.

Documentation

API Documentation: This tutorial explains how to document your APIs properly.

Man Pages: Writing and Generating Reference Manual Pages.

Application Automation and Scripting

D-Bus

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.
Accessing D-Bus Interfaces: A step-by-step guide to calling D-Bus methods and connecting to D-Bus signals using QtDBus.
Intermediate D-Bus: Tips to make use of QtDBus when faced with problematic real-world interfaces.
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.
D-Bus Autostart Services: Turn your application into a D-Bus autostart service with this tutorial. This D-Bus feature, also known as "D-Bus service activation", 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.
Porting from DCOP to D-Bus: Port your applications from DCOP to D-Bus with this handy guide.

Konqueror

Creating Konqueror Service Menus: This tutorial shows you how to create mimetype-specific actions in Konqueror's context menu (aka "servicemenus").
