Sets the bounds of item based on the result of using. This method tries to handle cases where the item being constrained adjusts its size after a bounds change. This would be the case for an item that maintains an aspect ratio for example. The calculation is run a second time in these cases to allow any constraint to adjust as needed.

Inherited functions

distanceToNext

abstract fun distanceToNext(carousel: Carousel<T, *>, position: CarouselBehavior.Presenter.Position, offset: Vector2D, items: (CarouselBehavior.Presenter.Position) -> Carousel.PresentedItem?): CarouselBehavior.Presenter.Distance

A Carousel will call this method when trying to do manual movement. This is a fundamentally different problem than it needs to solve when skipping through items (interpolate between indexes). This requires mapping pixel offsets to indexes. Only a Carousel's Presenter knows how items are laid out and can provide any information about "distance" between them. Hence, this API.

present

abstract fun present(carousel: Carousel<T, *>, position: CarouselBehavior.Presenter.Position, progressToNext: Float, supplementalViews: List<View>, items: (at: CarouselBehavior.Presenter.Position) -> Carousel.PresentedItem?): CarouselBehavior.Presenter.Presentation

Called by Carousel to update the Presentation it should display.

update

fun Carousel<T, *>.update()

Indicate that the stage is outdated and suggest the Carousel invoke present.
