Lawand writes "Nokia today released Qt 4.6, the latest version of the cross-platform application and UI framework. Featuring new platform support, powerful new graphical capabilities and support for multi-touch and gestures, and this is the first release to include significant code contributed from the community. This release introduces support for the Symbian platform with integration for the S60 framework, expanding the addressable market for Qt applications by over 130 million Symbian devices."

sobral writes "Following the announcement of the LGPL license model, since yesterday the Qt source code repositories are open to the public together with their roadmap. The contribution model is online and will enable developers from the community to submit patches through a single click process, avoiding the previous hassle of sending in signed paperwork. The code is hosted at qt.gitorious.org and an instant benefit of this launch is that Qt Software has been working together with Gitorious maintainers for the last four months to improve Gitorious and all these new features are already submitted upstream."

sekra writes "A new project called QGtkStyle by Trolltech Labs gives Qt4 based applications the possibility to integrate natively into Gtk based desktops like Gnome or Xfce. Instead of simply imitating Gtk styles QGtkStyle uses the Gtk theme engine directly. The project is still considered experimental, but is another step into better integration between Qt and Gtk applications. A project at Google Code has been set up as well." Anything that makes the various excellent Free software desktops work better together deserves kudos.

QtPi writes "Trolltech has announced the availability of Qt 4.4, the cross-platform software development framework. Ars Technica has an in-depth look at the release, which include an integrated WebKit-based HTML rendering engine, the new Phonon multimedia framework, support for Windows CE, and significant improvements to the QGraphicsView system. 'Qt 4.4 brings a lot of rich new capabilities to the toolkit that are sure to please open source and commercial software developers. It sounds like Trolltech already has some nice plans for Qt 4.5, and we will hopefully get to hear more about the long-term roadmap after Nokia completes its acquisition.'"

The bid was for 16 NOK per share, which values the company at an equivalent of approximately 150 million USD. The stock currently trades at 15.70 on the Oslo stack exchange, up from around 10 on Friday. The offer has already been accepted by the Trolltech BOD."

phobos13013 writes "Trolltech announced this week that they will discontinue development on their Greenphone platform. The Greenphone was advertised to be the first phone with a user-modifiable environment. Trolltech CTO Benoit Schilling stated that they are not really a hardware company and so will focus their efforts on FIC's Neo 1973, now available. However, Schilling hinted at a future Wi-Fi-enabled endeavor (possibly a VOIP phone)."

Provataki writes "Trolltech has announced that they are releasing the new version of Qtopia Phone Edition under the GPL along with a port on the FIC Neo1973 smartphone. Trolltech also continues to support Greenphone as a reference platform for mobile development within the company and through its partners. Benoit Schillings, CTO of Trolltech (also of BeOS fame as one of the original Be, Inc. engineers) commented on the news."

The 3D hardware accelerated image compositing OpenGL part of Cairo will be provided by the Glitz library. Cairo is 'possible' to be part of Qt 4.x at a later date, according to Trolltech's Qt 4 technical preview document."

The lead developer Henrik Johnson was hired by Quest Software to work further on TOra. After some time of inactivity, Henrik has put a request on the developer list, saying: 'I'm sorry for not being able to spend that much time on TOra as I should. I am now working full time on future versions of TOAD by Quest. (...) I am wondering if someone on this mailing list is willing to step up as a new maintainer of this project.' Also interesting is that the GPL'ed code base compiles for both Windows and Linux, but compiling for Windows is not allowed anymore because of the license of Trolltech's QT."

Karma Sucks writes "In 'A Taste of Qt 4', Trolltech reveals that it is positioning Qt 4 directly against Java. Qt 4 promises to be smaller and faster than its predecessors and there will be a boatload of new features including support for non-GUI applications and accessibility under Linux using Sun's ATK. More controversial is the introduction of a new and elegant foreach construct. Incidentally, for those still opposed to Qt's moc preprocessor, Havoc has some interesting comments. It is possible the idea will be adapted to provide GObject introspection in the future."

Supp0rtLinux writes "According to this article over at Linux Devices and noted on here at NewsForge.com, Motorola has released a newer version of its A76x line of cellular phones. This newest release, the A768, boasts of open source softwares from Monta Vista Linux, Trolltech, and Sleepycat. The only downside is that it appears to only be available in China right now. And the older A760 released last August is still only available in Europe and Asia. Why are we in the U.S. always the last to get new cellular toys? The good news, though, is that with a Linux base and an integrated PDA and MS Office file compatibility, at least syncing this to either a Linux system or a Windows one should be fairly seamless.

Alex Moskalyuk writes "Before Sun monopolized the notion of 'write once, run everywhere,' those who enjoy programming in C++ had the choice of using Qt libraries that provide cross-platform GUI support. C++ GUI Programming with Qt3 is written by the employees of TrollTech, the company that created and currently distributes the Qt environment." Read on for the rest of Alex's review. C++ GUI Programming with Qt 3 author Jasmin Blanchette, Mark Summerfield pages 464 publisher Prentice Hall PTR rating 9 reviewer Alex Moskalyuk ISBN 0131240722 summary Practical introduction into GUI programming with Qt

The first question that came to mind when I got this book - is there any need for it? Qt's Documentation is detailed and extensive with how-to's and an API reference available online for free. I have done GUI development in .NET (with C#) and Tk (with Perl) environments, and even though I've never tried Qt, the site with tutorials looked like a sufficiently good resource to start.

However, after getting through the first few chapters, religiously trying out the code, my opinions on whether a separate book is needed have changed. Jasmin Blanchette and Mark Summerfield's book can take a sufficiently clueless newbie with some C++ knowledge and guide him through the intricacies of GUI building, providing practical advice and some bits of experience on the way. You learn about the practicality of this book by turning to page 3 (with page 1 being the title) and seeing a code example as the second paragraph of the first chapter. Writing a basic GUI application in C++/Qt is attractively easy, to win you over and make you read the rest of the chapter, as well as finish the basic introduction by creating a windowed application with SpinBox and Slider widgets.

The table of contents is available on the publisher's Web site and looks fairly simple. Each chapter takes about 20-30 pages, with screenshots and code examples provided as part of the text. Reading the first 5 chapters, which comprise the "Basic Qt" section and take up 110 pages, should be enough for any C++ developer to build a sufficiently complex GUI application if all that's required is some graphical interface slapped on top of the functionality that's already there.

The rest of the book -- "Intermediate Qt" chapters -- take the reader into the common problems of GUI development, providing some insight into more advanced topics as well. Supporting networking, working with graphics and images, internationalization of the software application, interacting with help, reading XML through SAX and DOM APIs, accessing databases and doing inter-process communication are all covered here. The authors tended to avoid inserting huge amounts of reference material into the book, and, for example, in the XML chapter when working with Unicode you will be told to go online and download the numeric values of the Unicode characters instead of dedicating valuable book pages to it.

The language of the book is simple to follow; there are plenty of code examples (with discussion following each), and when the authors make certain choices, they also explain why. The diagrams and screenshots are clear (although not in color), and the code examples can be easily separated from the text. This is the first official TrollTech guide to Qt 3.2 programming, and the authors promise that the techniques will work with Qt 4.

Perhaps part of the positive impression that this book left is the fact that programming in Qt is easy and straightforward. At the early stages of my education, I started learning GUI programming with MFC, which left an indelible image of complexity and will probably increase psychiatrist bills in the future (to be fair to Microsoft, Windows Forms with .NET is a huge step forward). The book and the Qt library made some complex things sound quite simple and enjoyable to program. As Matthias Ettrich notes in the foreword to this book, the most important point in reasoning why Qt is so popular is "because programmers like it."

The book comes with a CD that contains non-commercial version of Qt 3.2 for Windows/Mac/Linux, Borland C++ 5.5 (Non-Commercial) and trial version of Borland C++ 6.0 compilers, SQLite database engine and book source code. The non-commercial version of Qt 3.2 for Windows can be installed for Borland C++ 5.5, Borland C++ 6.0, Microsoft Visual C++ 6 and Microsoft Visual C++.NET environments. The examples are quite conveniently located in folders with chapter numbers, followed by subfolders with example names.

Whether you're looking for general introduction to GUI development with C++ or trying to learn Qt, having worked with other libraries and toolkits before, this book is a good source of practical information and reference. The book is part of Perens' Open Source Series.

The book comes with a CD that contains non-commercial version of Qt 3.2 for Windows/Mac/Linux, Borland C++ 5.5 (Non-Commercial) and trial version of Borland C++ 6.0 compilers, SQLite database engine and book source code. The non-commercial version of Qt 3.2 for Windows can be installed for Borland C++ 5.5, Borland C++ 6.0, Microsoft Visual C++ 6 and Microsoft Visual C++.NET environments. The examples are quite conveniently located in folders with chapter numbers, followed by subfolders with example names.

Whether you're looking for general introduction to GUI development with C++ or trying to learn Qt, having worked with other libraries and toolkits before, this book is a good source of practical information and reference. The book is part of Perens' Open Source Series.

Alex Moskalyuk writes "Before Sun monopolized the notion of 'write once, run everywhere,' those who enjoy programming in C++ had the choice of using Qt libraries that provide cross-platform GUI support. C++ GUI Programming with Qt3 is written by the employees of TrollTech, the company that created and currently distributes the Qt environment." Read on for the rest of Alex's review.

The first question that came to mind when I got this book - is there any need for it? Qt's Documentation is detailed and extensive with how-to's and an API reference available online for free. I have done GUI development in .NET (with C#) and Tk (with Perl) environments, and even though I've never tried Qt, the site with tutorials looked like a sufficiently good resource to start.

However, after getting through the first few chapters, religiously trying out the code, my opinions on whether a separate book is needed have changed. Jasmin Blanchette and Mark Summerfield's book can take a sufficiently clueless newbie with some C++ knowledge and guide him through the intricacies of GUI building, providing practical advice and some bits of experience on the way. You learn about the practicality of this book by turning to page 3 (with page 1 being the title) and seeing a code example as the second paragraph of the first chapter. Writing a basic GUI application in C++/Qt is attractively easy, to win you over and make you read the rest of the chapter, as well as finish the basic introduction by creating a windowed application with SpinBox and Slider widgets.

The table of contents is available on the publisher's Web site and looks fairly simple. Each chapter takes about 20-30 pages, with screenshots and code examples provided as part of the text. Reading the first 5 chapters, which comprise the "Basic Qt" section and take up 110 pages, should be enough for any C++ developer to build a sufficiently complex GUI application if all that's required is some graphical interface slapped on top of the functionality that's already there.

The rest of the book -- "Intermediate Qt" chapters -- take the reader into the common problems of GUI development, providing some insight into more advanced topics as well. Supporting networking, working with graphics and images, internationalization of the software application, interacting with help, reading XML through SAX and DOM APIs, accessing databases and doing inter-process communication are all covered here. The authors tended to avoid inserting huge amounts of reference material into the book, and, for example, in the XML chapter when working with Unicode you will be told to go online and download the numeric values of the Unicode characters instead of dedicating valuable book pages to it.

The language of the book is simple to follow; there are plenty of code examples (with discussion following each), and when the authors make certain choices, they also explain why. The diagrams and screenshots are clear (although not in color), and the code examples can be easily separated from the text. This is the first official TrollTech guide to Qt 3.2 programming, and the authors promise that the techniques will work with Qt 4.

Perhaps part of the positive impression that this book left is the fact that programming in Qt is easy and straightforward. At the early stages of my education, I started learning GUI programming with MFC, which left an indelible image of complexity and will probably increase psychiatrist bills in the future (to be fair to Microsoft, Windows Forms with .NET is a huge step forward). The book and the Qt library made some complex things sound quite simple and enjoyable to program. As Matthias Ettrich notes in the foreword to this book, the most important point in reasoning why Qt is so popular is "because programmers like it."

An anonymous reader submits "Trolltech has quietly discontinued their non-commercial version of Qt for Windows. This eliminates Qt as a choice for those wanting to develop free multi-platform software." Actually, according to the linked page, "if you write Free software (Open Source software covered by the GPL) you are welcome to download and use the Free Edition of Qt," and Trolltech points out that one can buy the current edition of Qt -- seems fair enough.

lems1 writes "Start compiling the excuses you will tell your boss to upgrade your cell phone now. Motorola has opted to use Trolltech's Qtopia to power up the next generation of SmartPhones. Get the scoop/specs from here and a nice high-res picture from this other link. The phone will have 'digital camera, video player, MP3 player, speakerphone, advanced messaging, instant Internet access and Bluetooth wireless technology' capabilities. On top of being Linux-based of course." Update: 11/12 00:44 GMT by T : Yep, this is the same phone mentioned a few weeks ago.

An anonymous reader writes "According to a Linux Devices news item, Royal is preparing to release a Linux PDA before the end of this year with a price point of under $300. The device will use Trolltech's Qtopia, so it will share a common operating environment and application platform with the Sharp Zaurus Linux PDAs. Royal announced a Linux PDA in January 2002, but apparently discontinued that project and embarked on a new design. The Linux Devices story includes a photo of the earlier version."
