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.

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 a vCard data model, vCard input/output, contact group management, locale-aware address formatting, and localized country name to ISO 3166-1 alpha 2 code mapping and vice verca.

KCrash provides support for intercepting and handling application crashes.

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.

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

KWindowSystem provides information about and allows interaction with the windowing system. It provides a high level API, which is windowing system independent and has platform specific implementations. This API is inspired by X11 and thus not all functionality is available on all windowing systems.

In addition to the high level API, this framework also provides several lower level classes for interaction with the X Windowing System.

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

This is a style for QtQuickControls2 which is using QWidget's QStyle to paint the controls in order to give it a native look and feel.

Prison is a Qt-based barcode abstraction layer/library and provides uniform access to generation of barcodes with data.

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

This is a stand-alone implementation of the Kate syntax highlighting engine. It's meant as a building block for text editors as well as for simple highlighted text rendering (e.g. as HTML), supporting both integration with a custom editor as well as a ready-to-use QSyntaxHighlighter sub-class.

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.

This framework consists of the following components:

• Libraries for use in applications.

• QML bindings for the above.

• A server application.

• A management and analytics application.

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

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.

The KNewStuff library implements collaborative data sharing for applications. It uses libattica to support the Open Collaboration Services specification.

KItemViews includes a set of views, which can be used with item models. It includes views for categorizing lists and to add search filters to flat and hierarchical lists.

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

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

Kdeinit is a process launcher similar to init used for booting UNIX. It launches processes by forking and then loading a dynamic library which contains a kdemain(…) function. Using kdeinit to launch KDE applications makes starting KDE applications faster and reduces memory consumption.

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

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

KDNSSD is a library for handling the DNS-based Service Discovery Protocol (DNS-SD), the layer of Zeroconf that allows network services, such as printers, to be discovered without any user intervention or centralized infrastructure.
