This library provides a C++ API that determines holiday and other special events for a geographical region.

KTextEditor provides a powerful text editor component that you can embed in your application, either as a KPart or using the KF5::TextEditor library.

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

This library provides access to and handling of calendar data. It supports the standard formats iCalendar and vCalendar and the group scheduling standard iTIP.

A calendar contains information like incidences (events, to-dos, journals), alarms, time zones, and other useful information. This API provides access to that calendar information via well known calendar formats iCalendar (or iCal) and the older vCalendar.

This library provides primitives to interface with pseudo terminal devices as well as a KProcess derived class for running child processes and communicating with them using a pty.

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 provides additional image format plugins for QtGui. As such it is not required for the compilation of any other software, but may be a runtime requirement for Qt-based software to support certain image formats.

KCodecs provide a collection of methods to manipulate strings using various encodings.

It can automatically determine the charset of a string, translate XML entities, validate email addresses, and find encodings by name in a more tolerant way than QTextCodec (useful e.g. for data coming from the Internet).

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.

This framework contains an interface to KWallet, a safe desktop-wide storage for passwords and the kwalletd daemon used to safely store the passwords on KDE work spaces.

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.

A library for rendering SVG-based themes with stylesheet re-coloring and on-disk caching.

This framework contains scripts and data for building API documentation (dox) in a standard format and style for KDE.

For the actual documentation extraction and formatting the Doxygen tool is used, but this framework provides a wrapper script to make generating the documentation more convenient (including reading settings from the target framework or other module) and a standard template for the generated documentation.

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.

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

KDeclarative provides integration of QML and KDE work spaces. It's comprises two parts: a library used by the C++ part of your application to integrate QML with KDE Frameworks specific features, and a series of QML imports that offer bindings to some of the Frameworks.

The Package framework lets the user install and load packages of non binary content such as scripted extensions or graphic assets, as if they were traditional plugins.

Provided are action classes that can be added to toolbars or menus, a wide range of widgets for selecting characters, fonts, colors, actions, dates and times, or MIME types, as well as platform-aware dialogs for configuration pages, message boxes, and password requests.

KDED stands for KDE Daemon. KDED runs in the background and performs a number of small tasks. Some of these tasks are built in, others are started on demand.

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

KCrash provides support for intercepting and handling application crashes.

This package provides Kirigami components usable by both touch and desktop experiences.

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

KI18n provides functionality for internationalizing user interface text in applications, based on the GNU Gettext translation system. It wraps the standard Gettext functionality, so that the programmers and translators can use the familiar Gettext tools and workflows.

KI18n provides additional functionality as well, for both programmers and translators, which can help to achieve a higher overall quality of source and translated text. This includes argument capturing, customizable markup, and translation scripting.
