Published Thursday October 30th, 2014 | by

We are happy to announce that we released Qt Creator 3.3 beta1 today.

editordraganddrop

It comes with enhanced support for splitting editors and additional editor windows. You can now drag & drop editors between splits by dragging the new file type icon, next to the document drop down (see screenshot). Hold the Ctrl key (or Option key on OS X) to open another editor on the same document, instead of moving it. The navigation views (such as Projects and Open Documents) also support dragging files onto splits. Dropping files from the system onto a Qt Creator window now will also open the file in the appropriate split.

Qt 5.4 Beta Available

Published Friday October 17th, 2014 | by

I am extremely happy to announce that Qt 5.4 Beta is now available for download. There are a lot of new and interesting things in Qt 5.4 and I will try to summarize the most important highlights in this blog post.

Powerful Web Offering with Qt WebEngine

As the importance of HTML5 has grown we want to provide the best support for HTML5 within the Qt technology offering. The Qt WebEngine, a long-term R&D project based on the Chromium web engine has now reached fully supported version on desktop and embedded platforms.

Qt WebEngine provides a convenient API for both Qt Widgets and Qt Quick for using the Chromium web engine. Besides plain web viewing purposes Qt WebEngine takes full benefit of the whole Qt graphics stack integration allowing you to mix and overlay native Qt controls with web contents and OpenGL shaders. Of course, the fact that Qt provides a full application framework around the web engine makes Qt WebEngine truly an unparalled web engine API.

The new Qt WebChannel module acts as the bridge between QML/C++ and HTML/JavaScript allowing you to expose QObjects into the web context.

For platforms that do not allow distribution of Qt WebEngine as well as use cases where a full-blown web engine is not needed Qt 5.4 will introduce a technology preview of a new module called Qt WebView. It supports embedding the native web engines of the underlying operating system into Qt, and is currently available for Android and iOS. Because of this, Qt WebView also gives a convenient light-weight solution for simple web document integration. Qt WebView will be available with Qt 5.4 final as a separate add-on.

Qt Weekly #19: QOpenGLWidget

Published Wednesday September 10th, 2014 | by

After Qt 5.3′s introduction of QQuickWidget, Qt 5.4 adds QOpenGLWidget, the long-awaited replacement for the legacy QGLWidget. This widget retains the familiar initializeGL/resizeGL/paintGL API, while enabling full interoperability with other widgets in complex user interfaces.

Internally QOpenGLWidget is built on the same technology as QQuickWidget. Unlike QGLWidget, it is not a native window and will not turn any siblings or ancestors into native either. This avoids stacking, clipping, focus and performance issues and is expected to behave identically across all supported platforms.

Adding LGPL v3 to Qt

Published Wednesday August 20th, 2014 | by

20 years ago, Trolltech, the company that created Qt, was founded. One of its founding principles was to release Qt as free software to the open source community. In the early versions, this was limited to Unix/Linux and the X11 windowing system. Over the years, more and more platforms were included into the open source version of Qt.

At the same time, the licenses under which Qt was available evolved. The Qt 1.x source code was still released under a rather restrictive license. With Qt 2, we moved over to the QPL. Some years later, with Qt 4.0, Qt started to embrace the GPL v2, to remove some license conflicts between GPL-based applications and the QPL.

Trolltech was involved in talks with the Free Software Foundation (FSF) when the GPL v3 was created, and we added this license as an optional license for Qt after it was published by the FSF. Finally, in 2009 Nokia added LGPL v2.1 as a licensing option to Qt.

The spirit of all GNU licenses is about a strong copyleft, giving users rather strong access and rights to the source code of application and libraries. It was always meant to protect the users’ freedom to modify the application and underlying libraries and run the modified application.

Qt Creator 3.2.0 released

Published Tuesday August 19th, 2014 | by

We are happy to announce the Qt Creator 3.2.0 release today. This release adds many smaller and larger features, as well as fixing bugs. A few examples:

  • Block selections in text editors now allow you to do “column editing”, meaning that all selected lines are edited simultaneously (Qt Creator Manual)
  • Context help can now be configured to open in an external window (without disabling Help mode)
  • Support for C99 designated initializers and concatenated strings was added to the C++ code model, as well as improvements to encoding handling and lambda support and many other things
  • More panes are now searchable with Ctrl+F, for example the project tree
  • The QML profiler received many performance and stability improvements again

Enterprise Qt Creator users can now also use the QML profiler to debug their JavaScript memory usage in QML. (This is only available when using Qt 5.4 for the debugged application.)

Also have a look at our change log, for a more complete overview. I also want to thank the more than 50 contributors to this version of Qt Creator.

You find the opensource version on the Qt Project download page, and Enterprise packages on the Qt Account Portal. Please post issues in our bug tracker. You also can find us on IRC on #qt-creator on irc.freenode.net, and on the Qt Creator mailing list.

Note: With Qt Creator 3.2 we drop support for OS X 10.6 (Snow Leopard). The technical reason for this is that Apple does not support any kind of C++11 on that OS version. Of course that does not affect on which platforms you can run your Qt applications on. But it is not possible to run the Qt Creator 3.2 binaries on 10.6, and it also is not possible to compile Qt Creator 3.2 on 10.6 with the tool chains provided by Apple.

Defragmenting Qt and Uniting Our Ecosystem

Published Wednesday August 6th, 2014 | by

Over the last years, many changes have been happening in the Qt ecosystem. One of the biggest was the creation of Qt Project where Qt is now being developed as an open source project. The Qt Project was created to provide a space open for all to further develop and foster innovation for the Qt technology.

Qt has always been a commercial product. During the Trolltech days licensing income funded development of the product. While Nokia’s motivations were different, at Digia, our goal is to again make sure that Qt thrives for all industries, all companies, all users no matter what platform. That said, we need to make sure the business of selling Qt as a product is successful in order to fund its future development for the good of everyone in our ecosystem. The importance of Digia’s commercial business for securing the future of Qt cannot be underestimated as it drives Qt’s foundation and everyday operations. A look into the commit statistics shows that around 75% of all code submissions to qt-project.org come from Digia employees. In addition, Digia manages the release process and the CI and testing infrastructure, thus covering more than 85% of the costs of developing Qt.
