Introduction to the Plasmoid QML Declarative API

This document provides an overview/reference of the Declarative QML API for Plasmoids. It isn't a full binding to all of Qt or KDE's libraries, but a focused set of bindings designed to make writing Plasmoids fast and easy, while remaining powerful.

The API in this documentation covers the API of the Plasma specific QML components, so only the Declarative part of the API.

The QML ScriptEngine is bassed upon the Plasma JavaScript engine, making the API of the JavaScript part identical to the one of the JavaScript plasmoids engine. To see the api of the global Plasmoid object, see the JavaScript API documentation. (TODO: the JavaScript api paged should probably be copied and stripped down the imperative bits not present there, it would make harder to update tough)

What Is A Simplified JavaScript Plasmoid?

To denote that this Plasmoid is a Declarative widget, ensure that in the metadata.desktop file there is this line:

X-Plasma-API=declarativeappletscript

What follows is a description of the Plasma declarative classes instantiable from QML.
