Detailed Description

ScrollView Page Path Effect.

This effect causes Actors to follow a given path. The opacity of the actor will be 0.0 at the beginning of the path and will go to 1.0 as it is approximating to half of the path to return to 0.0 at the end of the path.

ScrollView | Page (1..n)

You should ensure ScrollView's default constraints have been removed, by calling ScrollView::RemoveConstraintsFromChildren() before applying this effect to ScrollView.

Manual operation: ApplyToPage(...) method should be called on every page.

Automatic operation: not implemented.

Since:
3.0, DALi version 1.0.0
