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: Rc<dyn Fn((usize, usize, &Option<T>)) -> Option<VNode>>

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

scroll_with_arrows: bool

Implementations

impl<T> VirtualScrollViewProps<T>where T: 'static + Clone,

pub fn builder( ) -> VirtualScrollViewPropsBuilder<((), (), (), (), (), (), (), ()), 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<T> Clone for VirtualScrollViewProps<T>where T: Clone + 'static,

fn clone(&self) -> VirtualScrollViewProps<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Properties for VirtualScrollViewProps<T>where T: 'static + Clone,

type Builder = VirtualScrollViewPropsBuilder<((), (), (), (), (), (), (), ()), T>

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

fn builder() -> <VirtualScrollViewProps<T> as Properties>::Builder

Create a builder for this component.

fn memoize(&self, other: &VirtualScrollViewProps<T>) -> bool

Compare two props to see if they are memoizable.
