Properties for the VirtualScrollView component.

Fields

theme: Option<ScrollViewThemeWith>

Theme override.

scrollbar_theme: Option<ScrollBarThemeWith>

Theme override for the scrollbars.

length: usize

Quantity of items in the VirtualScrollView.

item_size: f32

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

builder: Builder

The item builder function.

builder_args: Option<BuilderArgs>

The values for the item 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.

cache_elements: bool

Cache elements or not, changing builder_args will invalidate the cache if enabled. Default is true.

scroll_controller: Option<ScrollController>

Implementations

impl<Builder, BuilderArgs> VirtualScrollViewProps<Builder, BuilderArgs>

where Builder: 'static + Clone + Fn(usize, &Option<BuilderArgs>) -> Result<VNode, RenderError>, BuilderArgs: Clone + 'static + PartialEq,

pub fn builder( ) -> VirtualScrollViewPropsBuilder<((), (), (), (), (), (), (), (), (), (), ()), Builder, BuilderArgs>

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

Trait Implementations

impl<Builder, BuilderArgs> Clone for VirtualScrollViewProps<Builder, BuilderArgs>

where Builder: Clone + 'static + Fn(usize, &Option<BuilderArgs>) -> Result<VNode, RenderError>, BuilderArgs: Clone + 'static + PartialEq,

fn clone(&self) -> VirtualScrollViewProps<Builder, BuilderArgs>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<BuilderArgs, Builder> PartialEq for VirtualScrollViewProps<Builder, BuilderArgs>

where BuilderArgs: Clone + PartialEq, Builder: Clone + Fn(usize, &Option<BuilderArgs>) -> Result<VNode, RenderError>,

fn eq(&self, other: &VirtualScrollViewProps<Builder, BuilderArgs>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<Builder, BuilderArgs> Properties for VirtualScrollViewProps<Builder, BuilderArgs>

where Builder: 'static + Clone + Fn(usize, &Option<BuilderArgs>) -> Result<VNode, RenderError>, BuilderArgs: Clone + 'static + PartialEq, VirtualScrollViewProps<Builder, BuilderArgs>: Clone,

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

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

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

Create a builder for this component.

fn memoize( &mut self, new: &VirtualScrollViewProps<Builder, BuilderArgs> ) -> bool

Make the old props equal to the new props. Return if the props were equal and should be memoized.

fn into_vcomponent<M>( self, render_fn: impl ComponentFunction<Self, M> ) -> VComponent

where M: 'static,

Create a component from the props.
