Qt 4.8.0 available (and pics of the Qt teams!)

| December 16, 2011 | 27 Replies

Qt 4.8.0 was released yesterday featuring Qt Platform Abstraction, threaded OpenGL support, multithreaded HTTP and optimized file system access, making Qt apps even better by the day.

Please check out the Qt download page over at: http://qt.nokia.com/downloads.

Feedback can be left at the Qt bug tracker: https://bugreports.qt.nokia.com/secure/Dashboard.jspa

  • Qt Platform Abstraction (QPA)

 QPA restructures the GUI stack to enable easier porting of Qt to different windowing systems and devices. More info on: Lighthouse has grown up now.

  • Threaded OpenGL support

Enables those of us that are not OpenGL-ninjas to render OpenGL from more than one thread concurrently. More info on: Threaded OpenGL in 4.8.

  • Multithreaded HTTP

HTTP requests are now handled in a separate thread by default. This should make application guis smoother, as networking will no longer use the main event loop.

  • Optimized file system access

The file system stack received some heavy lifting under the hood. The result is better I/O performance, achieved by reducing the number of system calls performed for I/O and by better use of cached data, when available. The improvements in performance can be seen across all platforms.

Here are the teams behind it – possibly the only type of troll you’d want to meet in real life, the Nokia TrollTech Qt teams.

Brisbane Team

Munich Team

  3. lordstar says:

    This will make the qt platform more competitive. Let’s just see if developers are still willing to make apps for qt.

  4. manpreet says:

    I believe Nokia Belle is based on Qt 4.7.4 and it will be updated to 4.8 sometime next year (according to the post). Qt is a great platform, though Creator sux, it is even inferior to Nokia’s Carbide (except for gui tool) and not even close to Dev Studio or xCode. Regardless, if they want to position it as eye candy for poor people it will likely work but will have appropriate margins.
