What design language does Aaron OS use
Qt's new commercial LTS strategy brings some problems to open source projects like KDE. But the community is now helping itself.
So far, an agreement with the KDE community has forced a certain degree of openness from Qt. A hard fork could change that in the medium term.
The Qt company is freezing the public LTS branches of its framework. Updates should only be available for paying customers.
Version 6 of the UI framework Qt is intended to simplify the use of graphics APIs. A new LTS version is to follow in 2021.

The Qt team is preparing for the upcoming version 6. LTS support for the current version will also be limited.
The corona crisis is apparently causing financial difficulties at Qt and the company is considering drastic measures. The KDE community warns.
The versions with long-term support of the Qt framework and the offline installer will only be available with a commercial license in the future. The open source community is now discussing the effects of the change.
The upcoming version 6 of the UI framework Qt is supposed to be more evolution than revolution. Important construction sites will be a complete overhaul of QML and the focus on new graphic interfaces.
The free drawing application Krita and the Qt framework used for it should get HDR support. A lot of work has to be done before the stable release and so far this is only supported under Windows anyway.
For the current Qt 5.11, the team has completely revised the QML engine and disclosed the ahead-of-time compiler for it. The framework also improves accessibility under Windows as well as HTTP / 2 and Unicode support.
Thanks to web assembly, Qt applications will soon be able to run in the browser, some demo pages already show examples. But there are still plenty of obstacles to porting.
With the current version 5.10 of Qt, UIs can be streamed via WebGL, multi-touch inputs can be better edited and QtQuick controls can be implemented using images. In addition, Qt can now use OpenSSL 1.1 and provides better random numbers.
The development team has revised its own tools for the current Qt 5.9. This should simplify the long-term maintenance of the framework. Qt 5.9 also improves the 3D functions and reduces the size of the binary code.
Design software for 3D surfaces from Nvidia will be part of the Qt framework in the future. The several hundred thousand lines of code should be available as open source and thus be able to offer the Qt ecosystem modern 3D tools.
The current version 5.9 of the KDE plasma desktop enables the use of global menus, which are also known from Ubuntus Unity or MacOS. The team has also continued to refine the design and usage, and improve Wayland support.31.01.201727 CommentsVideo
The KDE team plans to discontinue all applications of the outdated 4 series in the medium term, as these have not yet been ported to Qt5. The final end is planned for the end of next year, so maintainers would have almost 3 years for their port.
Probably the most important innovation of the new version 5.8 of the KDE plasma desktop is the planned long-term care of at least 18 months. In addition, the team continued to work on the look and feel and redesigned an application using the Kirigami components that also run on Android.05/10/20167 CommentsVideo
KDE's in-house IDE, Kdevelop, no longer uses its own analysis software in version 5.0, but instead relies on Clang, which has a number of advantages. Thanks to Qt5, a Windows port will also be possible in the future.
The browser, which was previously only available to Qt customers, is now available under a free license. The Chromium-based browser was part of the Qt for Device Creation demo and follows the new licensing scheme.
The new version 5.1 of Virtualbox relies on Qt5 for the surface. The Oracle tool development team has also reworked the audio functionality and significantly improved performance in certain situations.
The Qt team actually scrapped their webkit module and replaced it with the use of Chromium. The community is working on a new Webkit module, which is now available as a preview.
New license terms apply to the current version 5.7 of the Qt UI framework. The Qt company uses this to provide some previously proprietary modules as free software. The KDE developers are already making use of this.
With Ubuntus Snappy and Flatpak, the former XDG app, the distribution of software under Linux is to be fundamentally simplified. The KDE team is working on implementing both techniques for its applications.
Stable basis and no compromises: With Neon, the KDE developers are creating a package source that is supposed to offer an up-to-date version of the plasma desktop and some applications. The first stable version is now available for users.
Qt 5.6 was released months later than planned. The new version of the framework will be maintained for at least three years. Support for Windows 10 and very high resolutions have been improved.
At a hackathon in the summer, the KDE developers want to discuss their experiences with operating systems apart from classic Linux. The goal is more ported applications for Windows, Mac OS X and mobile operating systems.
The openness of the Qt source code is now secured for all supported operating systems in the long term. In the future, Qt will also use the LGPLv3. Some previously proprietary parts are to be disclosed.
From now on, everyone should be able to contribute to the development of the Plasma Mobile smartphone interface. There is great enthusiasm for this at the Akademy, because now the work and the handicrafts are only just beginning. The KDE community is already gaining new members.

After failed demos and the idea of Plasma Active on the Vivaldi tablet, the KDE community tries again on a mobile port. The developer Sebastian Kügler shows the new Plasma 5 on a Nexus 5 with Android at the Akademy. The product should be competitive in a year.07/25/2015 79 CommentsVideo
With the new version 5.5 of Qt, WebGL can be used easily in Qt Quick, and OpenGL can also be used more easily. In addition, it is now possible to use route planning, and the framework is prepared for Windows 10.
At the KDE annual conference in July, some developers want to show how their technology could also be used on mobile devices - a project that has already failed once. There will also be lectures on the community itself and on new techniques such as Wayland.
The KDE developer David Edmundson shows that very high resolutions can be implemented relatively easily by the team using the latest technology. However, this could also lead to unwanted inconsistencies in the surface.
The current version of the LXDE Qt port uses some of the KDE Framework 5 libraries and relies fully on Qt 5. The desktop project still has problems with the basic libraries.
With the current plasma version of KDE, the Breeze design language becomes dominant. In addition, the team continued to port software, implemented other helpful little things and even integrated an application from Kubuntu.
While in 2014 there were always controversial discussions about Debian, Systemd and Limux, others have successfully rebuilt and are now relying on new technology. And a small company, with a lot of support, made an old idea socially acceptable.

Ports on Qt5 and Frameworks 5 of the KDE applications are available for the first time. Together with improvements to programs of the 4 series, the team now offers the collection under a new version scheme.
The release of Qt 5.4 offers new techniques for the integration of web content, full WinRT support and many improvements to the graphic components. There is also a new license and new options for commercial customers.
The porting work of the PIM components to the KDE Frameworks 5 and Qt5 is progressing well, as Aaron Seigo reports. Schedules for the release of the libraries, Kontact 5 and a newly created Akonadi are to follow.
In an interview, the developer Thomas Voss explains the technical differences between Wayland and Mir. But he can also be carried away to say that Me will be more relevant than Wayland.
The free VLC player will support the Wayland display server under Linux. The code for this comes from Rémi Denis-Courmont and allows the use of OpenGL and OpenGL ES under Wayland. The port on Qt 5 is also progressing.
With Plasma 5.1, the KDE team is bringing back some frequently used widgets and offering alternatives to them with a click of the mouse. The design of the user interface is now easier to change, and Qt4 applications also get the new look. In addition, the window management now supports the use under Wayland.
Unity 8, which is based on Qt5, will only become standard with Ubuntu 16.04, confirms the new desktop boss. Until then, the old and new versions will be developed in parallel and the new desktop is ready for testing.
Self-optimization is also possible through brain waves, proves the shooter Sebastiano Galazzo. He demonstrates other uses of the EEG with a game written with Qt. The technology should be open source and it should be possible to port it to Android and iOS.10/10/20140 CommentsVideo
The Qt business and Digia are very different. The realignment in the Qt company and the close amalgamation of free and commercial variants should significantly strengthen the framework with its large and differentiated ecosystem, says chief developer Lars Knoll.
In order to remain successful, the Qt framework will have to adapt even more to industry trends in the future, says chief developer Lars Knoll. This includes the control of devices via tablet, app stores on the desktop and cloud computing for evaluating data.
The spin-off of Digia's Qt business will be simply called The Qt Company. There is already a new website that bundles information on the commercial and free Qt version.
The new weaving engine will appear on Chromium with Qt 5.4, and the WinRT platform should also be fully supported. The Android port and graphics functions have also been improved. The first alpha can now be tested.
The KDE community prides itself on the low level of corporate influence. And although there are no products for sale, the project is well funded. But that doesn't work without committed hackers.
