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.

ThreadWeaver is a helper for multithreaded programming. It uses a job-based interface to queue tasks and execute them in an efficient way.

This library provides tools to annotate images.

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.

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

The Qt Cryptographic Architecture (QCA) provides a straightforward and cross-platform API for a range of cryptographic features, including SSL/TLS, X.509 certificates, SASL, OpenPGP, S/MIME CMS, and smart cards.

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

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.

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.

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

KCoreAddons provides classes built on top of QtCore to perform various tasks such as manipulating mime types, autosaving files, creating backup files, generating random sequences, performing text manipulations such as macro replacement, accessing user information and many more.

KService provides a plugin framework for handling desktop services. Services can be applications or libraries. They can be bound to MIME types or handled by application specific code.

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

KUnitConversion provides functions to convert values in different physical units. It supports converting different prefixes (e.g. kilo, mega, giga) as well as converting between different unit systems (e.g. liters, gallons).

KCrash provides support for intercepting and handling application crashes.

KColorPicker is a subclass of QToolButton with color popup menu which lets you select a color. The popup features a color dialog button which can be used to add custom colors to the popup menu.

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.

The Plasma workspace provides an application called KRunner which, among other things, allows one to type into a text area which causes various actions and information that match the text appear as the text is being typed.

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.

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

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.

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.

KDESU provides functionality for building GUI front ends for (password asking) console mode programs. kdesu and kdessh use it to interface with su and ssh respectively.
