Struct ScrollBase 

pub struct ScrollBase {
    pub offset: Vector2D<usize>,
    pub viewport: Vector2D<usize>,
    pub render_size: TPoint,
    pub scroll_viewer: Weak<RefCell<ScrollViewer>>,
}

Base struct for storing different information required for the Scrollable trait Has all fns of Scrollable but doesn’t implement the trait

Fields

offset: Vector2D<usize>

Offset of the base 0,0 coordinate (as in rendering)

viewport: Vector2D<usize>

Viewport for the whole content to be rendered

render_size: TPoint

Actual size rendered

scroll_viewer: Weak<RefCell<ScrollViewer>>

Weak reference to the owning scroll viewer

Implementations
