Contents

QML 1.0

Plasmoids that use the QML (aka QtQuick) declarative language to describe their user interface while having the logic of the applet, in JavaScript (QML is essentially a forge between CSS and JavaScript).

This is now the recommended method of creating plasmoids, where possible. The plasmoid, or applet serves as the visualization for the data which a Plasma::DataEngine contains.

It allows easily the declaring of an interface and to easily create things like ListViews with native Plasma theming. It is what Plasma is leaning the most towards, especially in the Mobile, MediaCenter shells.

Getting Started
Creating and running your first plasmoid in QML
Basic List Plasmoid
Make a QML ListView which displays basic text objects as items. Utilizes native Plasma theming and animations.
API Reference
The QML Plasmoid API. Useful for referencing what is available in the runtime, what are the differences with the pure JavaScript ScriptEngine, the differences between pure Qt QML and Plasma, and as a study aid for the tutorials above.

C++

Plasmoids

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.
How to use extenders in your Plasmoid
A simple example that shows how to use extenders in a Plasmoid.
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.

DataEngines

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..

PackageStructures

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.

Runners

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.

Wallpapers

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.
Wallpaper Tutorial 3
This tutorial improves the wallpaper by using the so-called 'double buffer' technique.

Plasma Shells

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.

Containment actions

Creating a Plasma ContainmentAction
"This tutorial covers the essentials of writing a new Plasma ContainmentAction. You can use a ContainmentAction e.g. for desktop context menus."

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.

Plasmoids

Getting Started
Creating and running your first plasmoid in JavaScript
Getting Data
How to retrieve 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.

QML 2.0

Plasmoids that use the QML 2.0 declarative language to describe their user interface while having the logic of the applet, in JavaScript.

This is now the recommended method of creating plasmoids, where possible. The plasmoid, or applet serves as the visualization for the data which a Plasma::DataEngine contains.

It allows easily the declaring of an interface and to easily create things like ListViews with native Plasma theming. It is what Plasma is leaning the most towards, especially in the Mobile, MediaCenter shells.

Getting Started
