Development/Tutorials/Plasma4/ContainmentAction
You can use Plasma ContainmentAction e.g. for Context Menus on your Plasma Desktop. They will run as plugins meaning you can add and remove them after compilation. If they exist, their name will be stored in .desktop files.
Example
A simple example for Plasma ContainmentAction plugins can be found at https://github.com/tstaerk/kde-contextmenu/tree/0.1. Let's look at it here:
