PDAs, Cellphones, Wireless "Don't expect RIM to open source its entire operating system, or its radio stack. But the original smartphone company is gambling its future success on open source, and it has an expert on board to help. Mary Branscombe asked Senior Technical Director for Open Software, Eduardo Pelegri Llopart, where open source fits in at RIM."

The most interesting stuff is the Qt snippet:

"The Cascades 3D graphics framework uses Qt Core, and QML (the Qt Modelling Language) to give PlayBook 2 and BlackBerry 10 apps a new signature look."

I don't actually know if this information has been officially stated anywhere before. Using QML, RIM could create an absolutely competitive user experience, on par with iOS and WP7 (on framerate and fluidity), and easily exceeding Android UX.

And this is something that will get much better on Qt5, when the graphics model becomes more directly GPU accelerateable (ok, that's not a real word).

And once that absolutely competitive user experience is there and short before hitting the market like a bomb Microsoft comes along, partners with RIM, the absolutely competitive user experience is dead before released and RIM loses half it's merit in just some months?

It was part of the BlackBerry DevCon key note by Alec Saunders
http://www.blackberrydevcon.com/europe/webcast (Qt part beginning at about 41:15, including a demo of QtQuick on the Playbook by Lars Knoll)

I believe that RIM's QML-using framework Cascades referred to in the article is already using an OpenGL ES scene graph for rendering.

Cool, thanks for the info! Also Intel was planning to retrofit the Scene Graph for Qt 4.8, before butchering MeeGo.
