"This tutorial aims to demonstrate how easy it is to write plugins for KDE 2 using KParts. It took me about 20 minutes to get my first plugin working, and hopefully after reading this, you will find it just as straight forward. The same mechanism applies to any KPart based application, so once you understand what's here you should be able to write plugins for pretty much any application or component in KDE!"

"KPart based applications such as Konqueror allow you to dynamically load components and actions, and provide facilities to merge the UIs of these components with that of the application. This sounds really complicated, but all it means to us is that the KParts framework does all the work, and we can pretty much forget about it. We write our code as normal, then write a little piece of boiler plate code and an XML file to set things going."

"To KParts, a plugin is a way to extend an application, a part, or even another plugin. A plugin is only an extension to something else, and can't be used on its own. The most visible way plugins extend applications is by adding new commands to the menus and toolbars, in KParts these are automatically integrated with those of the host application using XML and KActions. In addition to this automatic functionality, the plugin can use the standard KParts interfaces and those defined by the parent application to add or change the behaviour of its host."
