KTextTemplate is to make it easier for application developers to separate the structure of documents from the data they contain.

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

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.

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.

KFileMetaData provides a simple library for extracting the text and metadata from a number of different files. This library is typically used by file indexers to retrieve the metadata. This library can also be used by applications to write metadata.

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.

KArchive provides classes for easy reading, creation and manipulation of archive formats like ZIP and TAR.

It also provides transparent compression and decompression of data, like the GZip format, via a subclass of QIODevice.

Baloo provides file searching and indexing. It does so by maintaining an index of the contents of your files.

KFileMetaData provides a simple library for extracting the text and metadata from a number of different files. This library is typically used by file indexers to retrieve the metadata. This library can also be used by applications to write metadata.

ModemManagerQt provides access to all ModemManager features exposed on DBus. It allows you to manage modem devices and access to information available for your modem devices, like signal, location and messages.

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.

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.

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.

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.

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

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

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

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

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

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.

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 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.

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.
