VirtualScrollView component properties.

Fields

theme: Option<ScrollViewThemeWith>

Theme override.

length: usize

Quantity of items in the VirtualScrollView.

item_size: f32

Size of the items, height for vertical direction and width for horizontal.

builder: Box<dyn Fn((usize, usize, &'a Scoped<'a, VirtualScrollViewProps<'a, T>>, &'a Option<T>)) -> LazyNodes<'a, 'a>>

The item builder function.

builder_values: Option<T>

Custom values to pass to the builder function.

direction: String

Direction of the VirtualScrollView, vertical or horizontal.

show_scrollbar: bool

Show the scrollbar, visible by default.

scroll_with_arrows: bool

Enable scrolling with arrow keys.

Implementations

impl<'a, T> VirtualScrollViewProps<'a, T>where T: 'a,

pub fn builder( ) -> VirtualScrollViewPropsBuilder<'a, ((), (), (), (), (), (), (), ()), T>

Create a builder for building VirtualScrollViewProps. On the builder, call .theme(...)(optional), .length(...), .item_size(...), .builder(...), .builder_values(...)(optional), .direction(...)(optional), .show_scrollbar(...)(optional), .scroll_with_arrows(...)(optional) to set the values of the fields. Finally, call .build() to create the instance of VirtualScrollViewProps.

Trait Implementations

impl<'a, T> Properties for VirtualScrollViewProps<'a, T>where T: 'a,

type Builder = VirtualScrollViewPropsBuilder<'a, ((), (), (), (), (), (), (), ()), T>

The type of the builder for this component. Used to create “in-progress” versions of the props.

const IS_STATIC: bool = false

An indication if these props are can be memoized automatically.

fn builder() -> <VirtualScrollViewProps<'a, T> as Properties>::Builder

Create a builder for this component.

unsafe fn memoize(&self, other: &VirtualScrollViewProps<'a, T>) -> bool

Memoization can only happen if the props are valid for the ’static lifetime
