Slashdot Mirror

An anonymous reader writes with news that, after a six year journey, Qt will once again be maintained by a standalone company. From the Digia weblog: ... Even though the open source project and the commercial side of Qt are highly dependent upon each other, they have over the last years drifted apart. ... Because of the separation between the open source and commercial offerings, we often end up competing against ourselves instead of competing against other technologies. ... We are now starting a conscious effort to overcome these problems. As you might have read, Digia has decided to move the Qt business into a company of its own. Thus we will soon have a company (owned by Digia), that will focus 100% on Qt. At the same time we would like to take the opportunity and retire qt.digia.com and merge it with the content from qt-project.org into a new unified web presence. The unified web page will give a broad overview of the Qt technology, both enterprise and open-source, from a technical, business and messaging perspective.

First time accepted submitter waslap writes "I have a leading role at a small software development company. I am responsible for giving guidance and making decisions on tool usage within the shop. I find the task of choosing frameworks to use within our team, and specifically UI frameworks, exceedingly difficult. A couple of years back my investigation of RIA frameworks lead me to eventually push for Adobe Flex [adobe.com] as the UI framework of choice for our future web development. This was long before anyone would have guessed that Adobe would abandon the Linux version of Flash. I chose Flex mainly for its maturity, wealth of documentation, commercial backing, and the superior abilities of Flash, at a time when HTML 5 was still in the early stages of planning. Conversely, about 15 years ago I made a switch to Qt for desktop applications and it is still around and thriving. I am trying to understand why it was the right choice and the others not. Perhaps Qt's design was done so well that it could not be improved. I'm not sure whether that assessment is accurate. I cannot find a sound decision-tree based on my experiences to assist me in making choices that have staying power. I hope the esteemed Slashdot readers can provide helpful input on the matter. We need a set of fail-safe axioms" Read on for more context. The backing of Adobe, an industry giant, gave me what I later discovered was a false sense of security. I thought that the Flex framework would not get lost in a back alley like so many open source projects. We invested heavily in Flex and were disillusioned a couple of years later when Linux support for Flash was ended. (Linux support is vital for us for reasons outside this discussion.)

I had evaluated Adobe Flex alongside OpenLaszlo, which at the time had the ability to use a DHTML back-end instead of Flash with the flick of a switch. In retrospect, this alone apparently made it a better choice in the long run regardless of its flaky state when I first looked at it.

A similar scenario arose with CodeIgniter, which we chose for getting away from classical spaghetti PHP. CodeIgniter was recently dropped after we've invested a Tesla Model X worth of money into using it. (EllisLab Seeking New Owner for CodeIgniter.)

I am standing at a cross-roads once again as people are pushing Laravel [laravel.com] for PHP, and giving other suggestions. I am scratching my (sore) head and wondering how to prevent eventual failures in the future. It seems there is no way to predict whether a tool will survive.

Even in retrospect, when I consider my decision-making processes, everything was reasonable at the time I made the choices, yet some turned out to be wrong.

Jolla's Sailfish, Canonical's recently announced Ubuntu Phone, and KDE's Plasma Active environments are all using Qt5's QML for interface design. Unfortunately, the set of UI components provided by each, although similar, are incompatible with the others. After a chat on IRC between developers of all three platforms, they've decided to discuss the reasons behind each implementation, in the hopes that they can work toward a common architecture. "There are also discussions underway regarding other aspects of the bigger puzzle such as common package formats and delivery strategies. We are poised, should we keep our heads straight and our feet moving, to evolve that holiest of grails in the mobile space: an open and vendor neutral application development strategy built around the commonality of QtQuick and Linux. This is our Rome, which will not be built in a day, but which can become something significant in the world if we keep our heads and follow through."

sfcrazy writes "The Qt project and Digia, the company behind Qt framework, have released the most awaited C++ framework for developers, Qt 5.0. The company claims it's one of the best releases to date and has invested a significant amount of time behind this release. It's an overhaul of the Qt 4.x series and makes Qt fit for the future." Update: 12/19 17:46 GMT by U L : Major new features include an overhauled graphics layer, full integration of Qt Quick for creating flexible interfaces using Javascript, and increased modularization including the first steps toward de-emphasizing QtWidgets by separating them into their own module.

First time accepted submitter MrvFD writes "Ever since the most recent layoffs were announced by Nokia last month and the end of Qt related programs at Nokia was rumored, the fate of Qt has been in the air despite it nowadays having a working open governance model. Fear no longer, Qt brand, since Digia has now announced acquiring the Qt organization from Nokia. While relatively unknown company to the masses, it has already been selling the non-free (non-LGPL) licenses of Qt for 1.5 years. Hopefully this'll mean a bright future for Qt in co-operation with other Qt wielding companies like Google, RIM, Canonical, Intel, Skype, Microsoft, Jolla and the thousands of Qt open source and commercial license users. Digia now plans to quickly enable Qt on Android, iOS and Windows 8 platforms, where work has already been underway for some time."

An anonymous reader writes "One day after word leaked out that Nokia is shutting down its Qt Australia office, which is responsible for Qt3D, QtDeclarative, QtLocation, QtMultimedia, QtSensors, and QtSystems, reports are beginning to surface that Nokia is trying to sell off all Qt assets." Seems like selling itself to Nokia wasn't the best option for Trolltech after all.

After nine months of effort, Nokia's Qt Lab has announced the availability of the alpha release of Qt 5. Goals achieved for this release include a new platform abstraction layer, a re-architected graphics stack, and the inclusion of Qt Quick as a first-class citizen (hitting version 2.0, and using Google's V8 Javascript engine to boot). Quoting Lars Knoll: "'Qt 5 should be the foundation for a new way of developing applications. While offering all of the power of native Qt using C++, the focus should shift to a model, where C++ is mainly used to implement modular backend functionality for Qt Quick.' I can say that we came a good way closer to this vision with Qt 5.0. The model is working nicely on the embedded side of Qt where UIs are full screen. On the desktop, we have laid most of the foundations required for this model, but it’ll take us until 5.1 or 5.2 to really take this into use." Nokia has posted the the source and detailed release notes on the Qt wiki.

New submitter sirjohn writes with the good news that "A small group of ICS and Nokia engineers have started working on a minimal bootstrap to bring fully functional Qt 5" to the Raspberry Pi, writing "Do you want to create the next big thing on embedded devices and have $35 to invest? You can now have a complete development environment with accelerated graphics for basically nothing. I think it's a big deal ..." Plus, Nokia is funding 400 of the boards and looking for ideas (and developers) to use them. The competition is stiff; there are already quite a few impressive ideas listed.

chill writes "Over the past year the Qt Developers have been working to sort out how they can make development of Qt even more inclusive and open. After exploring various options, they are now almost ready to go live with the new solution. It's taken a little longer than expected, but they are now very close to moving hosting of Qt to a new domain: qt-project.org [domain not yet live when posted]. The domain will be owned by a non-profit foundation whose only purpose is to host the infrastructure for the Qt project. More details of the changes are available at the Qt Open Governance Model wiki."
