• Qt 4.7.0 String Freeze (Qt Labs)
  Qt 4.7.0 string freeze is now in effect. No changes to strings will be accepted from this point. Qt aims at being fully internationalized by use of its own i18n framework.

• Designing code for QML UIs (Qt Labs)
  QML is starting to approach its initial release.

• When being wrong is right (Qt Labs)
  I like July. There are many good things about this month, like having no snow in Oslo or no night in Oslo (technically we do, but it’s an hour or two long only). Another one of them is, like Harald said, vacations. And though I like mine very much, the one I’m thinking of is [...]

• D’oh! (Qt Labs)
  We screwed up! A serious bug in Qt 4.6.3’s QtOpenGL module on Windows went undetected through reviewing, the auto-test system and quality assurance! The bug causes a device context leak, and after 9999 repaints, the program stops updating its widgets. The bug is fixed in our repositories and will not appear in our next releases. [...]

  One of the new Mobility API is the Telephony API. This API can be used in other applications to detect incoming phone call events.

• Fun things you can do with the Nokia Qt SDK (Qt Labs)
  Recently I presented a small Qt 4.6 based demo on the LinuxTag in Berlin, as an example of something you could do with the Nokia Qt SDK. It combined existing projects like the Tiled map editor and the Box2D physics library with Qt Mobility’s sensors API for reading out the accelerometer. It looks like this [...]

• A Lighthouse by any other name… (Qt Labs)
  Just a quick heads-up that we have chosen a new name for the Lighthouse platform (as discussed the Remodelling post). The Subcommittee of Renaming has been hard at work in the intervening months, reviewing and considering all the 17576 possible TLAs. We ended up with: QPA. Unfortunately, the precise meaning was lost in the subcommittee paperwork, so [...]

• Qt Creator 2.0 (Qt Labs)
  A major focus of the 2.0 release is the support for developing Qt applications for Symbian and Maemo. I think, we have made great progress to make it easy and fun to develop for Symbian and Maemo.
