Enum OverscrollBehavior

pub enum OverscrollBehavior {
    Chain,
    Contain,
}

Expand description

Controls whether a scrollable surface chains scroll events to its ancestor when it reaches a boundary — the equivalent of CSS overscroll-behavior.

Variants§

Chain

At a boundary, decline the event (Ignored) so it propagates to the next ancestor scrollable. The default (overscroll-behavior: auto).

Note: a scrollable whose content fits entirely (nothing to scroll on either axis) is always at its boundary, so under Chain it lets the wheel through to an ancestor rather than swallowing it. This matches the web; set Contain on a fit-to-content panel that should absorb the wheel regardless.

Contain

Always absorb the event (Handled), even at the boundary — no chaining. Equivalent to overscroll-behavior: contain.

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
