Trait ScrollbarHandle 

pub trait ScrollbarHandle: 'static {
    // Required methods
    fn offset(&self) -> Point<Pixels>;
    fn set_offset(&self, offset: Point<Pixels>);
    fn content_size(&self) -> Size<Pixels>;

    // Provided methods
    fn start_drag(&self) { ... }
    fn end_drag(&self) { ... }
}

A trait for scroll handles that can get and set offset.

Required Methods

fn offset(&self) -> Point<Pixels>

Get the current offset of the scroll handle.

fn set_offset(&self, offset: Point<Pixels>)

Set the offset of the scroll handle.

fn content_size(&self) -> Size<Pixels>

The full size of the content, including padding.

Provided Methods

fn start_drag(&self)

Called when start dragging the scrollbar thumb.

fn end_drag(&self)

Called when end dragging the scrollbar thumb.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
