Qt 4

Qt Quick has been around for a little while now, helping developers make great looking, responsive user interfaces. And it is nice to see so many applications in Ovi Store utilizing this new technology. But we want to keep taking it further and one of the ways we’re doing that is by adding ready-made UI [...]

As you might know, Qt has had support for IPv6 since quite some time. Now we have made some changes in Qt5 that relate to IPv6: Shane has improved the support for binding TCP and UDP sockets. Originally there was QHostAddress::Any which meant any IPv4 (0.0.0.0). Then at some point QHostAddress::AnyIPv6 was introduced to mean [...]

Qt has a set of auto tests that we use for regression testing and inside our CI infrastructure to prevent bad commits from entering our source tree With Qt more and more moving into open governance, people need a way to properly run those auto tests. Some of the network tests depend on the qt-test-server [...]

At the moment we have already implemented the following features: Take into account LC_MESSAGES, LC_TIME ... [More] , etc environment variables on Linux/Unix platforms; Added writing script support to QLocale; Added some currency support (the feedback [...] [Less]

We are neck deep in the final preparations for the Qt Contributors’ Summit and we have a few points to share with you: First off, thanks to everyone who has listed their topics for our event. It is looking like we are going to get a lot of really great discussions going and we can’t [...]

QString and QByteArray comes with very handy operator+ which allows you to write stuff like this: QString directory = /*...*/, name = /*...*/; QString dataFile = directory + QLatin1Char('/') + name + QLatin1String(".dat"); Very convenient. The ... [More] QLatin1Char and QLatin1String are just there for correctness, you could omit those while writing your application. We have something [...] [Less]

A couple of months ago, I posted a lengthy email to the internal discussion list about the problems with type punning and breaking of strict aliasing. At the time, my sole objective was to clean up any warnings in my build of Qt 4.7 when using GCC 4.5. Since then, GCC 4.6 was released and [...]
