KAuth provides a convenient, system-integrated way to offload actions that need to be performed as a privileged user to small set of helper utilities.

KBookmarks lets you access and manipulate bookmarks stored using the XBEL format.

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.

This library provides tools to annotate images.

KPlotWidget is a QWidget-derived class that provides a virtual base class for easy data-plotting. The idea behind KPlotWidget is that you only have to specify information in "data units", the natural units of the data being plotted. KPlotWidget automatically converts everything to screen pixel units.

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

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.

This library contains classes to improve the handling of icons in applications using the KDE Frameworks.

KConfigWidgets provides easy-to-use classes to create configuration dialogs, as well as a set of widgets which uses KConfig to store their settings.

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.

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.

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

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.

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

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.

This package provides library that is used when writing accessibility clients such as screen readers.

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.

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

KJobWIdgets provides widgets for showing progress of asynchronous jobs.

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

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 library contains classes to improve the handling of icons in applications using the KDE Frameworks.

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.
