    Qt - 20 years leading cross-platform development

    Today we celebrate 20 years since the first release of Qt was uploaded to sunsite.unc.edu and announced, six days later, at comp.os.linux.announce. Over these years, Qt evolved from a two person Norwegian project to a full-fledged, social-technical world-wide organism that underpins free software projects, profitable companies, universities, government-related organizations, and more. It's been an exciting journey.

    An user review about the current state of the KDE Plasma 5 on an Arch Linux Workstation.

    Digia straps Qt into ejector seat

    From Trolltech to Nokia and Nokia to Digia, the programming language Qt has had a challenging corporate life even though it retained fans among developers. Now, the language's next phase of life has begun in earnest, spun out of Digia into a separate subsidiary tasked with bringing the commercial and open source Qts back into alignment.

    Digia spins off Qt as subsidiary

    Digia has spun off a subsidiary called “The Qt Company” to unify Qt’s commercial and open source efforts, and debuted a low-cost plan for mobile developers. The Linux-oriented Qt cross-platform development framework has had a tumultuous career, having been passed around Scandinavia over the yearsfrom Trolltech to Nokia and then from Nokia to Digia.

    Does Intellectual Property Need a Redesign

    Patent law in the United States has always been framed with the intent to promote innovation. Because there has generally been a large amount of capital required to produce such innovations as the railroad, the airplane...

    Amarok and digiKam on Windows

    While I do believe that most people would be better off running Linux, I fully understand that for some people this is just not feasible, for one reason or another. Even I have to run Windows occasionally at work. Fortunately, some of my favorite Linux programs are gradually becoming available in Windows. This makes using Windows at least a bit more bearable for me.

    The Qt Future - Mobile on Nokia

    When Nokia acquired Trolltech, there was a question mark over Nokia's long term strategy for the Qt framework. Qt for many, is the toolkit behind the KDE desktop and it's associated applications, so what would a phone company do with it. Over the past years, the strategy has steadily crystallised, and at this years Qt Dev Day, Rich Green, the new CTO at Nokia and first Nokia CTO to speak at the annual Qt developer conference, confirmed that Qt is core to all of Nokia's plans for mobile applications; "We're betting the whole company and smartphones on Qt" Green told the audience at the opening keynote.

    Nokia’s Maemo OS – The next big wave

    Trends in computers come in waves. Developers are like surfers on the shore spying out the horizon looking out for the next big one. Today I write about a wave that is just now starting to take shape, looks almost innocuous, but that has the potential to be a great ride as well – Nokia’s Maemo operating system.

    Community Members Invited To Qt Developer Days 2009

    The last few years has seen the company formerly known as Trolltech open their arms to one of the largest parts of their supporting community, KDE, in a new way: By offering a few members of the KDE community free admittance to the Qt Developer Days conference. This year is no different, and they have invited a number of people to attend this year's conferences. Yes, that's plural: There are two conferences. One from the 12th to 14th of October in Munich, Germany and one from the 2nd to the 4th of November in San Francisco, USA.

    Qt Publishes Roadmap, Opens Up Git Repository

    Back in March we witnessed the release of Qt 4.5 which was also met by an announcement that Qt Extended was to be discontinued and that was just weeks after the announcement came down that Qt Jambi would be discontinued. There have certainly been many changes since Nokia bought out Trolltech and then renamed it to Qt Software...

    Nokia updates Qt open source developer platform

    KDE On Windows Challenges Microsoft On Its Own Turf

    When I first heard about the project of porting KDE on windows I was very skeptical of the reason behind it but not so much of the viability of such a project since Trolltech decided to release the Qt 4 license under GPL for the windows version. KDE on windows is an audacious project aimed at porting all KDE applications on MS Windows natively. KDE also has a similar project for Mac OSX.

    KDE Voted Free Software Project of the Year

    Linux Format magazine has unveiled its annual Reader Awards (PDF) for 2008 and KDE won a 'landslide' victory in the category of Free Software Project of the year in recognition of the 'incredible' work done with KDE 4. Amarok, Qt, Konqueror and the KDE-based Asus Eee PC were also recognised in the awards. Read on for more details of the KDE related successes.

    Nokia Puts the L in License

    This time last year, the big news from the-company-formerly-known-as-Trolltech — now Qt Software — was a takeover bid from mobile-phone giant Nokia, which closed successfully in June for an estimated €104 million. Once again January brings Trolltech/Qt news from Nokia, this time announcing that beginning with the upcoming 4.5 release, the Qt framework will be licensed under the GNU Lesser General Public License.

    LGPL License Option Added to Qt

    Nokia announces that its Qt cross-platform User Interface (UI) and application framework for desktop and embedded platforms will be available under the Lesser General Public License (LGPL) version 2.1 license from the release of Qt 4.5, scheduled for March 2009. Previously, Qt has been made available to the open source community under the General Public License (GPL) license.

    Qt Everywhere: 4.5 To Be Relicensed As LGPL

    Nokia has announced that starting with version 4.5, Qt will be available under the LGPL 2.1. From the announcement, "The move to LGPL licensing will provide open source and commercial developers with more permissive licensing than GPL and so increase flexibility for developers. In addition, Qt source code repositories will be made publicly available and will encourage contributions from desktop and embedded developer communities. With these changes, developers will be able to actively drive the evolution of the Qt framework."

    Mobile and Embedded Day at Akademy

    This year Akademy held a dedicated day for mobile and embedded talks. With Trolltech being owned by Nokia, mobile is suddenly a hot topic for KDE and several variants of Qt and KDE on mobiles were in progress at Akademy. Read on for an overview of the talks. The day opened with Kate Alhola from Nokia showing off the Nokia N810. As already reported, the talk was followed by handing out the devices to the audience. Her blog says she hopes to see lots of Qt and KDE applications in Maemo Garage soon.

    Integration at Akademy

    An important topic at Akademy is modularisation and integration. It has been the main topic of one talk but you will find it comes up in many others. It is clearly on the minds of many hackers here.

    Interview: Qt Comes to Mozilla and Firefox

    Developers from Nokia and Mozilla have been working hard to port the Mozilla Platform and Firefox to Qt and there are now some solid results available. An experimental build of Firefox Qt is available, and you can download the sources from Mozilla's mercurial repository. The plan is to merge the Qt branch into the central Mozilla branch to make the port official. KDE Dot News spoke to developer Oleg Romaxa from Nokia who came to Akademy 2008 from Finland.

    Qt 4.5 to Dramatically Improve QtWebKit and QGraphicsView Through Animations and Speed Ups

    At Akademy 2008 in Belgium, Qt developers Simon Hausmann and Andreas Aardal Hanssen announced dramatic improvements in the web browser engine in Qt and the canvas that is used by, for example, the Plasma desktop shell. Video support, animations and transitions, optimisations to speed up painting and animations, and new graphical effects open up nearly endless new possibilities for developers to present their user interfaces with.

    Tokamak Sprint Turns Plasma Upside-Down

    Tokamak, the first International meeting of Plasma was held in Milano in northern Italy over the last weekend. 14 people joined the fun and spent some days hacking on the KDE 4 desktop shell. For the most part, it was like meeting friends, only that some had never met each other in person before. The meeting was filled with small sessions, such as discussing target users for Plasma to optimise the Plasma interface for. Topics were target users, underlying technology, scripting, integration with other parts, webservice integration, visual presentation, porting of Plasma to new technology in Qt, Italian profanity and how everybody loves pizza.

    Closed source is dead, open source is the way to innovation!

    LXer Feature: 2-Jan-2008

    Lately, some articles appeared which stated the open-source way of development didn't bring us any innovation. Jaron Lanier even goes further by saying closed source is the better approach to innovation. However, these people miss a lot of important points and facts about innovation, and therefore the conclusions they make are false. Having read a lot about innovation myself lately, I will try to show that the open-source way of doing things leads to more innovation, and more important, I will give some real life examples showing the closed-source inventions aren't that innovative at all, and pointing to some open-source inventions the other writers missed.

    Phonon: Where QT and KDE meet

    Trolltech has recently announced that its graphic library Qt will be using Phonon, he new multimedia library created by the KDE developers. This is good news for Qt4 users allowing Qt to be better and simpler and it's a good sign of a great collaboration between Trolltech and the other Free software projects.

    Dear Glyn Moody

    Dear Glyn Moody: I found how you trotted out an age old and long since dealt with issue, namely the licensing of Qt1, as a way to discuss what you consider to be "the growing tensions between the KDE and GNOME camps" to be tasteless and ironic. If you want to help mend fences (we need all the hands we can get), the last thing to do is drag long-since dealt with issues that have been irrelevant for years back to the surface.

    Trolltech contributes new Phonon backends to KDE

    Trolltech, the company behind the Qt widget toolkit used in KDE, released today several new Phonon backends that facilitate cross-platform multimedia support. Phonon is media engine abstraction layer that was originally developed for KDE 4. Phonon simplifies multimedia application development and makes it possible to swap seamlessly between various underlying media libraries without having to reimplement application code.

    Trolltech Hosting Phonon Backends in KDE Subversion Repository

    Trolltech announced today that the Phonon backends, which they have been developing for inclusion in Qt, are being transferred into the KDE source code repository. Phonon is the KDE 4 API for multimedia and is also set to be part of Qt 4.4, scheduled for the end of Q1 2008. You heard it right folks, a part of Qt will be officially hosted and developed inside KDE's very own Subversion repository, from whose loins Phonon first sprung, and be freely available to all under the LGPL.

    Mobile Linux device stack gains motion detection

    Trolltech is extending its Qtopia embedded Linux development platform with iPhone-like motion control. Thanks to a partnership with motion-control software firm F-Origin, Qtopia developers will soon be able to trick out their mobile devices with interfaces that respond to landscape/portrait rotation, gestures, and gravity.

    Trolltech axes the Greenphone

    The Linux developer says it will now focus on its Qtopia platform and leave the hassles of hardware to other companies.

    The Book of QT 4: The Art of Building QT Applications

    One of the "holy grails" of software development is the ability to write a program that will operate across platforms without you (the coder) having to rewrite for each platform. Enter Qt 4, a toolkit used largely for developing GUI applications for Linux, UNIX, Mac, and Windows. Qt 4 seems to fit the bill and be the answer to this "crusade", but can the same be said about "The Book of QT 4"?

    Linux picks up pace on cellphones

    There has been growing talk of Linux's adoption on cellphone platforms. Yesterday Trolltech announced the release of its application platform under the GPL as well as a partnership with OpenMoko to do development on the Neo1973, the potential iPhone killer. A the same time Broadcom joined the Linux Mobile Foundation.
