Plasma Programming with C++

Getting Started With Plasmoids
Creating your first plasmoid in C++ with SVG background, icon and text
Getting Started With Plasmoids..Some more 
A few more starter's tips.
Writing a DataEngine
DataEngines provide a standardized interface to various (read only) data sources for visualizations to use. Learn what a DataEngine is and how to write one of your own.
Writing a Service
Services provide a standardized interface for visualizations to perform "write operations". This can be for example, uploading pasted test to a pastebin service..
Writing a PackageStructure Plugin
PackageStructure plugins allow custom Packages to be defined, installed, removed and listed as well as provide access their contents at runtime. Packages may contain any kind of data addons, including scripts.
How to use extenders in your Plasmoid
A simple example that shows how to use extenders in a Plasmoid.
Creating Runners
Runners are plugins that provide action-based search functionality in the Plasma workspace "run command" dialog. These plugins can be used by any application that links again libplasma.
Wallpaper Tutorial 1
This tutorial shows you how to make a simple Hello World plasma wallpaper plugin.
Wallpaper Tutorial 2
This tutorial covers how to add configuration options to the wallpaper.
Creating a Plasma Shell
This tutorial covers the essentials of writing a new Plasma shell from scratch. A must-read for anyone creating a new or modifying an existing Plasma Shell. Existing Plasma shells include Plasma Desktop, Plasma Netbook, Plasma Mobile, Plasma Media Center, Plasma Screensaver, Plasma KPart and Plasma KDM, and all follow the patterns documented here.
Creating Plasmoids
May 2010 article from Linux Magazine
Create Plasmoids using KDevelop
Article explaining the structure of Plasma and how to create a Plasmoid
Adding configuration to your plasmoid
Article explaining how to add a configuration dialog to your plasmoid.
Integrate Plasma in Applications
This tutorial shows you how to make an application dashboard based on Plasma technologies.

Plasma Programming with JavaScript

Plasma has built-in JavaScript (also known as ECMAScript, and often referred to as QtScript in the context of Qt) scripting support without requiring any external dependencies.


Getting Started
Creating and running your first plasmoid in JavaScript
Getting Data
How to retreive data from a data engine
Now Playing
Slightly more advanced data engine usage: displaying what's currently playing
System Monitor
How to access systemmonitor data engine
Cheat Sheet
A cheat sheet, rather than a tutorial, of things to remember and watch out for when developing JavaScript plasmoids
API Reference
The Simplified JavaScript Plasmoid API. Useful for referencing what is available in the runtime and as a study aid for the tutorials above.

Other Applications Of Javascript

Scripting Plasma Shells
The KDE Plasma Desktop and Netbook provide means to manage the desktop shell (desktop, panels, widget) via scripts written in JavaScript. This article describes how to take advantage of this feature set as well as documents the full API. This is primarily a system administration tool, but may also be of interest to power users.
Javascript Animations
How to write Animations using Javascript for use in Plasma applications
Creating Comic Plugins
This guide shows you how to create a comic plugin for the comic plasmoid.

Plasma Programming with Ruby

Getting Started
Creating and running your first plasmoid in Ruby
Using widgets
Introduction to using Plasma widgets
Writing a simple paste applet
A tutorial explaining how to set up a plasmoid, create a simple paste applet using widgets and add Plasma features seen elsewhere. Complete with tips for those who have never programmed before.
Writing DataEngines
How to write your own Plasma DataEngine using Ruby
Use SVG artwork in the simplest way possible
Follow a fellow student as he asks around about SVG usage and explains why the code examples work. This is a wiki so feel free to add your own insights until this tutorial can be considered complete.
