First release of KDE Frameworks 5
July 7th, 2014. The KDE Community is proud to announce KDE Frameworks 5.0. Frameworks 5 is the next generation of KDE libraries, modularized and optimized for easy integration in Qt applications. The Frameworks offer a wide variety of commonly needed functionality in mature, peer reviewed and well tested libraries with friendly licensing terms. There are over 50 different Frameworks as part of this release providing solutions including hardware integration, file format support, additional widgets, plotting functions, spell checking and more. Many of the Frameworks are cross platform and have minimal or no extra dependencies making them easy to build and add to any Qt application.
The KDE Frameworks represent an effort to rework the powerful KDE Platform 4 libraries into a set of independent, cross platform modules that will be readily available to all Qt developers to simplify, accelerate and reduce the cost of Qt development. The individual Frameworks are cross-platform and well documented and tested and their usage will be familiar to Qt developers, following the style and standards set by the Qt Project. Frameworks are developed under the proven KDE governance model with a predictable release schedule, a clear and vendor neutral contributor process, open governance and flexible licensing (LGPL).
The Frameworks have a clear dependency structure, divided into Categories and Tiers. The Categories refer to runtime dependencies:
- Functional elements have no runtime dependencies.
- Integration designates code that may require runtime dependencies for integration depending on what the OS or platform offers.
- Solutions have mandatory runtime dependencies.
The transition from Platform to Frameworks has been in progress for over 3 years, guided by top KDE technical contributors. Learn more about Frameworks 5 in this article from last year.
There are over 50 Frameworks currently available. Browse the complete set in the online API documentation. Below an impression of some of the functionality Frameworks offers to Qt application developers.
KArchive offers support for many popular compression codecs in a self-contained, featureful and easy-to-use file archiving and extracting library. Just feed it files; there's no need to reinvent an archiving function in your Qt-based application!
ThreadWeaver offers a high-level API to manage threads using job- and queue-based interfaces. It allows easy scheduling of thread execution by specifying dependencies between the threads and executing them satisfying these dependencies, greatly simplifying the use of multiple threads.
KConfig is a Framework to deal with storing and retrieving configuration settings. It features a group-oriented API. It works with INI files and XDG-compliant cascading directories. It generates code based on XML files.
Solid offers hardware detection and can inform an application about storage devices and volumes, CPU, battery status, power management, network status and interfaces, and Bluetooth. For encrypted partitions, power and networking, running daemons are required.
KI18n adds Gettext support to applications, making it easier to integrate the translation workflow of Qt applications in the general translation infrastructure of many projects.
On Linux, using packages for your favorite distribution is the recommended way to get access to KDE Frameworks.use kdesrc-build. Frameworks 5.0 requires Qt 5.2. It represents the first in a series of planned monthly releases making improvements available to developers in a quick and predictable manner. inqlude.org, the curated archive of Qt libraries. A complete list with API documentation is on api.kde.org.
ContributeThose interested in following and contributing to the development of Frameworks can check out the git repositories, follow the discussions on the KDE Frameworks Development mailing list and contribute patches through review board. Policies and the current state of the project and plans are available at the Frameworks wiki. Real-time discussions take place on the #kde-devel IRC channel on freenode.net. You can discuss and share ideas on this release in the comments section of the dot article.
