KDBusAddons provides convenience classes on top of QtDBus, as well as an API to create KDED modules.

The KDE GUI addons provide utilities for graphical user interfaces in the areas of colors, fonts, text, images, keyboard input.

Provides tools to generate documentation in various format from DocBook files.

This framework helps implement autocompletion in Qt-based applications. It provides a set of completion-ready widgets, or can be integrated it into your application's other widgets.

Solid is a device integration framework. It provides a way of querying and interacting with hardware independently of the underlying operating system.

KNotification is used to notify the user of an event. It covers feedback and persistent events.

KIdleTime is a singleton reporting information on idle time. It is useful not only for finding out about the current idle time of the PC, but also for getting notified upon idle time events, such as custom timeouts, or user activity.

This framework offers the possibility to create integrate services and actions on any application without having to implement them specifically. Purpose will offer them mechanisms to list the different alternatives to execute given the requested action type and will facilitate components so that all the plugins can receive all the information they need.

This library provides tools to annotate images.

KGlobalAccel allows you to have global accelerators that are independent of the focused window. Unlike regular shortcuts, the application's window does not need focus for them to be activated.

KItemModels provides the following models:

1. KBreadcrumbSelectionModel - Selects the parents of selected items to create breadcrumbs.

2. KCheckableProxyModel - Adds a checkable capability to a source model.

3. KConcatenateRowsProxyModel - Concatenates rows from multiple source models.

4. KDescendantsProxyModel - Proxy Model for restructuring a Tree into a list.

5. KExtraColumnsProxyModel - Adds columns after existing columns.

6. KLinkItemSelectionModel - Share a selection in multiple views which do not have the same source model.

7. KModelIndexProxyMapper - Mapping of indexes and selections through proxy models.

8. KRearrangeColumnsProxyModel - Can reorder and hide columns from the source model.

9. KRecursiveFilterProxyModel - Recursive filtering of models.

10. KSelectionProxyModel - A Proxy Model which presents a subset of its source model to observers

As the names suggest they implement a Client respectively a Server API for the Wayland protocol. The API is Qt-styled removing the needs to interact with a for a Qt developer uncomfortable low-level C-API. For example the callback mechanism from the Wayland API is replaced by signals, data types are adjusted to be what a Qt developer expects - two arguments of int are represented by a QPoint or a QSize.

This is a DAV protocol implementation with KJobs. Calendars and todos are supported, using either GroupDAV or CalDAV, and contacts are supported using GroupDAV or CardDAV.

KCMUtils provides various classes to work with KCModules. KCModules can be created with the KConfigWidgets framework.

Kirigami is a set of high level QtQuick components looking and feeling well on both mobile and desktop devices. They ease the creation of applications that follow the Kirigami Human Interface Guidelines.

Attica is a Qt library that implements the Open Collaboration Services API version 1.6.

It grants easy access to the services such as querying information about persons and contents. The library is used in KNewStuff3 as content provider. In order to integrate with KDE's Plasma Desktop, a platform plugin exists in kdebase.

The REST API is defined here: http://freedesktop.org/wiki/Specifications/open-collaboration-services/

This framework implements a lot of file management functions. It supports accessing files locally as well as via HTTP and FTP out of the box and can be extended by plugins to support other protocols as well. There is a variety of plugins available, e.g. to support access via SSH. The framework can also be used to bridge a native protocol to a file-based interface. This makes the data accessible in all applications using the KDE file dialog or any other KIO enabled infrastructure.

This library implements the framework for KDE parts, which are widgets with a user-interface defined in terms of actions.

KConfig provides an advanced configuration system. It is made of two parts: KConfigCore and KConfigGui.

KConfigCore provides access to the configuration files themselves. It features:

1. Code generation: describe your configuration in an XML file, and use `kconfig_compiler to generate classes that read and write configuration entries.

2. Cascading configuration files (global settings overridden by local settings).

3. Optional shell expansion support (see docs/options.md).

4. The ability to lock down configuration options (see docs/options.md).

KConfigGui provides a way to hook widgets to the configuration so that they are automatically initialized from the configuration and automatically propagate their changes to their respective configuration files.

Sonnet is a plugin-based spell checking library for Qt-based applications. It supports several different plugins, including HSpell, Enchant, ASpell and HUNSPELL.

This package contains XML files describing non-standard Wayland protocols used in KDE Plasma.

KNotifyConfig provides a configuration dialog for desktop notifications which can be embedded in your application.
