Abstract

cover services, .operations file, .operations dtd spec, perhaps make a service like the pastebin one or something. idk, something easy.

http://www.kde.org/standards/kcfg/1.0/kcfg.xsd

also mention how a service can access the dataengine via it's pointer(I think that's in public api), if it really really needs to(e.g. plasma-kdm can't live without that)

The Plasma Engine Explorer

A very useful tool for anyone writing services is the Plasma engine explorer. You can use it to see test services by launching them by running

<syntaxhighlight lang="bash"> plasmaengineexplorer

If the service you want to test is associated to a source, you can access a dialog to launch the service and set its parameters by using the contextual menu of the source and selecting "Get associated service"

The Code

This tutorial will cover adding a service associated with a source into an existing data engine.
