"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."
