Expand description

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

Implementations§

source§

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

source

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.
