[−][src]Module cursive_core::view::scroll

Core mechanisms to implement scrolling.

This module is still unstable and may go through breaking changes. In addition, it is private unless you enable the unstable_scroll feature.

This modules defines:

scroll::Core: stores the state variables required to handle scrolling. Any view that needs to implement scrolling should embed a scroll::Core.
- scroll::Scroller: a trait for something that embeds a such a scroll::Core.
Some free functions to help implement the usual View trait for a type implementing scroll::Scroller. Some methods, like View::call_on_any, are not affected by scrolling and are not covered here.
- The functions defined here will usually take a reference to the Scroller object, as well as closures to implement the "inner view".

ScrollView may be an easier way to add scrolling to an existing view.
