Since I don't want to take focus away from the 4.5.1 release, I'll keep this short. We have now released an updated version of the Animation Framework solution. There are not so many visible changes to the animation classes - besides bug fixes we renamed QAbstractAnimation::iterationCount back to QAbstractAnimation::loopCount. (You don't want to know how many times we have discussed the naming of that property). And let's not forget that sub-attaq now has animated explosions! (sorry, no video) But there are more interesting changes to the state machine classes. Hopefully, this will be the last solution before it gets merged into 4.6 so this might be one of your last chances of influencing it.
