We are planning to use TransitionPresenter with a custom Transition that provides 'swipe'-like functionality in response to touch events.. In particular the transition will follow the user's finger, if the finger is stopped then the transition will stop, if the finger is moved backwards then the transition will go backwards. Once the TouchUp event is raised, then the transition will complete like a normal animated transition, unless the position is less than a certain threshold, in which case the transition will revert to the original ('from') content, preferably animated as well.
We have implemented most of this functionality with a custom Transition, but are unable to do the last part (reverting to the 'from' content). Would it be possible to get a new CancelTransition method added to the Transition class to achieve this?
Note we also want to use standard animated transitions when the content change is triggered through other means (e.g. buttons), which is why we want to use TransitionPresenter instead of implementing something custom.
