Development on the Qt 5 tool-kit under the Qt Project is coming along in earnest as it gears up for release in 2012. Committed recently were some input improvements for Qt 5.

Commit 2ace610 to the Qt Git repository extends the touch events for Qt 5. This very large commit now allows touch events to express velocity, differentiate between touches with a finger or pen, raw positions, and more. Introducd as part of this commit is a new QTouchDevice class.

From a mailing list message, "The touch event API had been extended to make way for multi-touch, differentiating between pen and finger, velocity etc. I hope there is a working high-level API :)"

As part of X Input 2.2, which should be integrated into X.Org Server 1.12, there should be proper multi-touch support on the X side. The GNOME developers working on GTK+ have also been looking towards input improvements.
