"Animation and multi-touch
Qt 4.6 introduces a new Animation Framework, which lets developers animate Qt elements called QObjects, including QWidgets, and enables custom animations and interpolation functions. "Our main focus for 4.6 has been on our Animation Framework," said Kenchamanna. "It allows developers to create a very dynamic, fluid UI, with support for transitions and multi-touch. Animation performance is also improved, and we now offer a synchronized timer to better manage CPU utilization.

"New graphics effects are said to include opacity, drop shadows, glow, and filtering. In addition, animations can now controlled using easing curves and can be grouped together.

"The new multi-touch capabilities include gesture-based input methods such as flicking and kinetic scrolling (see the YouTube demo at the bottom of the page). Several basic gestures have been pre-programmed, with tools available for developing more advanced gesture input methods, said Kenchamanna. Due out next year, Maemo 6 will provide a full slate of gestures based on the technology, and the multi-touch effects will be widely used on netbooks running Linux and Windows 7, he added."
